SIEMENS S1000 system maintenance

Failure phenomenon:
Siemens S1000 color super machine, the boot into the ultrasonic working interface is normal, the heart probe is used normally, but the superficial probe and the abdominal probe can only be used normally in the 0B mode, can not be used in other modes, the machine has a card screen phenomenon at the same time.

Failure analysis:
The signal processing and control module of S1000 color supercomputer is mainly composed of probe interface module, input and output module and electronic system module. The electronic system module includes TR, CB, RC, BE, VI and RM board, TR, RC board and probe interface module ( The TI Module) performs the ultrasonic signal processing functions together, collectively referred to as the front end portion; the BE, VI, and RM boards are responsible for the subsequent processing of the ultrasonic signal data and the overall control functions of the machine, collectively referred to as the back end portion. The power supply consists of four sections, an AC AC power box, a PSA analgo power module, a PSD digital power module, and a QuickStart Battery.

Firstly, if the system software error occurs, the fault occurs. After the system is reinstalled, the fault still exists, and the system software fault may be eliminated. The problem of RC and BE is initially judged from the hardware function. As the real-time control board of the front end, the RC board is also responsible for the control function of ultrasonic transmission and reception. It is also responsible for analgo-to-digital conversion of the 192 channels of received data of the TR board, thereby converting the echo signals into digital signals, which is convenient for the back-end software. Further processing of the technology. A failure of the RC board will cause all other functions of the machine to be abnormal. The BE board receives the digitized echo signals from the front RC board and processes them according to the operator's requirements. The failure of the BE board often causes one of the functions of the color Doppler to be abnormal.

The PSA and TI can be considered by the hardware replacement exclusion method to eliminate the BE and RC failures. The TI board can support 3 probes at the same time and can be switched at will, but the probe hot swap is not supported. When the TI board fails, it will cause the 2D area to have no image, card screen or boot code "US_IMG_17" and other error codes. The PSA is responsible for the front end power supply and provides the probe working voltage. If the PSA fault will cause the probe to be caused by the abnormal voltage supply. The function is not working properly.


Repair results:
Replace the PSA power supply, all the functions of the machine are used normally, and the fault is eliminated.

GE VIVID I system maintainance

First, the failure phenomenon:
The machine starts normally, and after receiving the probe, it prompts an error and the probe is not recognized.

Second, the failure analysis:
The ultrasonic probe does not recognize the power supply that normally considers the probe interface board or supplies power to the probe interface board. The machine configuration diagram shows that there is no high-voltage switch on the interface board of the model, that is, it does not affect the high-voltage output of the DC power supply, so it can pass the detection. The DC output voltage directly determines whether there is a fault in the power supply. After the detection, the machine is found to have no high-voltage output, and it is determined that the DC power supply is faulty.

Third, testing and repair:
Replace the DC-DC power supply, the probe can be recognized normally after the machine is started, and each function resumes normal operation.

In genneral, we are really experted in ultrasound repair.

Aloka Alpha 10 system Maintenance

Fault conditions

The ALOKA &α10 machine abdomen probe has no echo, the superficial probe has only a weak echo, and the heart probe has a normal echo.

Failure analysis

Since the heart probe has a normal echo, it is necessary to first eliminate the fault caused by the probe itself, and replace the other abdominal probe for testing. The test result also has no echo, and the fault is determined by the hardware of the machine itself. There is a voltage output indicator on the IO board at the rear of the machine. It is found that the +70V indicator is not lit after the machine is started, and the +90V indicator is always on. +70V, +90V supply the working voltage of the probe to the machine, combined with the echo of the abdomen probe and the normal echo of the heart probe. The fault may be caused by insufficient voltage supply of the high voltage power supply.

Troubleshooting

After replacing the high voltage power supply EU-6031, the machine resumes normal use.

 

Repair Philips CX50 Blue Screen Fault

First, the failure phenomenon:
The machine has a blue screen when it is turned on and cannot be started normally.

Second, the failure analysis:
On-site consultation using the doctor learned that the machine did not make any changes to the machine hardware and software before the blue screen appeared, the blue screen code is 0x000000ED, the code generally points to the hard disk failure. After the machine is disassembled, the hard disk of the machine is detected. It is found that the hard disk has bad sectors, and the bad sectors of the hard disk often cause the hard disk to work normally and affect the startup of the machine. Since the direct repair of bad sectors of the hard disk will result in the loss of data of some sectors of the bad track, an attempt is made to check and repair the data of the hard disk to ensure that the color system software carried in the hard disk can operate normally.

Finally, testing and repair:
Repair the system hard disk and work normally after the machine restart.

Phililps CX30 System Maintenance

The phenomenon of failure:
The system is properly starting-up, but it will crash during use.

Failure analysis:
Crashing is mainly failure of main board, and the stuck interface prompts the discovery of a new keyboard. This may be a system driver failure resulting in incompatibility or a short circuit in the numeric keypad.
Reinstall the system, the fault remains the same, consider the numeric keypad failure, but the same problem occurs when disconnecting it from the control panel. This fault occurs only when users uses panel keys,then it is suspected that there is a short circuit in the control panel part. So it needs further testing.
The ultrasound machinevuses Windows XP system, then using a keyboard test software of the system can accurately detect whether the keyboard has any problems.
Even if the the numeric keypad and the control panel is disconnected, the failure is the same. So it can be determined that the fault is caused by the short circuit of the panel, which continuously triggers the system crash caused by the numeric keypad.

Testing and repair
Replace the control panel and the machine will return to normal.

ALOKA SSD-3500 Fault Repair

1.The fault phenomenon

After closing the switch, ssd-3500 color ultrasound was started. After the "Aloka" sign appeared in the startup process, the blue bar kept moving and the panel light kept shining. The system could not enter the normal ultrasonic diagnosis interface.

2.Failure analysis

When this happens, the first thing to think about is the CPU and HDD issues that are directly related to system startup.Since the machine's data processing platform is based on Microsoft's Windows operating system, just like ordinary computers, the boot process is basically the same.
In addition to the normal CPU and hard disk data reading in the startup process of the ultrasonic device, each image processing board containing flash should be confirmed for data, so as to determine whether there is any data loss or need to update data, so as to brush flash again in the startup process.The indicator light of the hard disk is flashing constantly during the boot process, indicating that the data of the hard disk is read and written constantly and the hard disk is troubleshooting.
Next, unplug and unplug each group of wires. After re-plugging and unplugging, the fault will remain after starting up.If it is suspected to be a CPU fault, take out the CPU board and observe it to see whether there is obvious burning down or insufficient heat dissipation causing component damage. After observation, it is normal.
After the discovery of the motherboard has a button battery, removed from the measurement of only 1.6v.It is inconsistent with the actual mark of 3V, and the voltage value is obviously not enough to support the normal reading and writing of the hardware part of the chip, resulting in problems in the data communication between the CPU and the hard disk, affecting the normal loading and data update of the device.

3.Exclusion and summary

After replacing a standard 3V battery, the device starts normally and enters the ultrasonic diagnosis interface for troubleshooting.
For ssd-3500 color doppler ultrasound startup, the blue bar after the "Aloka" sign& appears in the startup process keeps circulating and the panel light circulates and shines. The system cannot enter the normal ultrasonic diagnosis interface, which basically determines that the components or hard disk on the main board have problems.

ALOKA α5 color doppler ultrasound fault repair case

ALOKA alpha 5 is equipped with advanced front-end technology, original data processing platform,high-capacity digital beam generator (12bit digital beam generator) and other technologies to ensure the high-quality image of all organs in the body.And as well as the varties probes in ALOKA, ALOKA alpha 5 can meet the needs of linical diagnosis and scientific research,At present, ALOKA alpha 5 is used in many hospitals in China. Now we will analyze one of the common faults encountered in the use of ALOKA &α5.

Faults phenomenon

When operating the CW(continuous doppler), the diagnostic instrument crashed with an error prompt, and the other functions were all normal.Error warning: the machine detects abnormal voltage, please restart the system.

Failure analysis

(1)The CW function of the diagnostic instrument can only be used in cardiac, and it has no such function in other conditions, so the CW board may be damaged.
(2) in case the appearance of the fault, the working voltage of CW measured by the attached power box drops significantly, which may be caused by the attached power box.
(3) this fault may also be caused by CW signal and loss of communication function.
(4) the heart probe (phased array probe) is composed of PW and CW, and the heart probe may be damaged.
(5) the software system is damaged, resulting in the loss of CW function.

Troubleshooting

It’s not working after replacing the attached power box and related circuit boards,the dead phenomenon didn&’t appeared when the heart probe was replaced . The problem was e circuits of the machine appeared,the restart of the machine are required.

GE Logiq P6 color ultrasonic fault

1. Faults phenomenon

After reading the tags, you will not be able to enter the operation interface.

2. Faultsanalysis and troubleshooting

The loss of files is usually a system fault, and the system can be restored after reinstallation. According to the customer's feedback, there are important patient information and parameters in the machine. In order to maximize the customer's interests, we try to repair the system.
Since the prompt file is missing, it is theoretically possible to recover the lost or damaged file by filling in the missing or damaged file. At the same time, because the user cannot enter the operation interface normally, the abnormal information should be found through the log file.The operation steps are as follows:

Step 1: according to the prompt path, it can be known that this file is the user's default file. After opening this file, it is known that only some basic information and Settings of the machine are recorded in it, and relevant parameters required for diagnosis are not affected.

Step 2: copy the same file in another system for replacement, connect the machine to start up and use normally, and help the customer to backup the data again.

3.Summary

Color super data should develop the habit of regular backup, so as not to cause unnecessary trouble when failure.

Maintenance of GE LOGIQ P6 Color Doppler

Fault phenomenon

All probes of GE LOGIQ P6 machine have interference in color Doppler mode.

Fault analysis

LOGIQ P6 machine plate structure is simple, plate function integration is high. The color Doppler processing function of the machine is on the SYSCOM motherboard. Generally, this kind of interference is caused by probe failure, external interference or SYSCOM motherboard and APS power supply.
Due to the interference of all probes in the machine, the possibility of failure of all probes is very small, so other probabilities should be considered first. Pushing the machine to another floor room for testing, there are still interference faults to eliminate the possibility of external interference. APS power supply failure may cause interference of machine access voltage. APS power supply failure may be eliminated after replacing the test. Finally, the SYSCOM motherboard was replaced, and the machine started to work normally. All the probes entered the working mode of color Doppler without any interference and troubleshooting.

Summary

GE LOGIQ P6 is easier to maintain than other ultrasonic machines because of its simple plate structure. Maintenance is mainly based on the specific performance of the machine fault and the working principle of the machine to analyze the fault location and take corresponding treatment measures, for the more difficult to analyze and judge the fault location should be carefully and step by step investigation, avoid random attempted maintenance

GE Logiq P9 maintenance 

Fault phenomenon
Dark lines appeared in the ultrasound images. There is a dark line on the ultrasound image of GE Logiq9 color Doppler Ultrasound. There is no echo signal in the dark line area. When the image is formed, the position of the probe is moved, while the position of the dark line is always fixed.

Fault analysis
After scanning the machine probe with the coupling agent, it is found that the edge of the dark line of the
image is obvious. According to the analysis of the principle of the formation of the ultrasound image and the structure of the color Doppler ultrasound, the cause of the failure may be the problem of the corresponding probe wafer or the corresponding channel. Switching different probes for testing, it is found that each probe has the same dark line, and each probe has the possibility of wafer damage at the same time. It can eliminate the damage of the probe, and the failure may occur on the corresponding channel board. There are 8 channel boards in the front end of GE Logiq9 color Doppler Ultrasound. The corresponding ultrasonic transmitting and receiving and A/D conversion are carried out. Eight channel boards correspond to different probe channels. Each board processes 24 channels. Mark the corresponding dark line position, shutdown and switch channel board position on the display image. When switching to the fourth channel board, the corresponding dark line position on the image moves. Then cross-check with another channel board and the fourth channel board to determine that the fault occurs on the fourth channel board.
 
Repairing
The signal processing channel boards of modern high-end color Doppler Ultrasound usually have 2, 4 or even 8 boards. These channel boards are identical. When the image is dark, the positions between the channel boards can be changed. The replacement method is used to achieve the purpose of diagnosis and lock the fault parts accurately. The machine returned to normal after replacing the fourth passage board.

GE LOGIQ P5 Troubleshooting

Failure phenomenon
LOGIQ P5 has no response at start up.

Failure analysis
Switch ON the POWER, turn ON the main switch at the back of the machine, press the "POWER ON" button, the monitor and keyboard lights are off, the cooling fan is not turned, and the machine has no response.POWER ON cannot be activated when the UPS POWER supply and the main switch of the machine are restarted. The output voltage of UPS measured on fieldis 222V,which indicating that the POWER supply is normal.After turning on the main switch of the machine, the waiting light next to the transformer can be seen from the transformer cooling hole below the machine, showing that AC 220V has entered the machine.Press POWER ON at this time, still no response, suspected the machine internal POWER supply (APS) may be faulty.

Troubleshooting
Open the side cover of the machine, observe the APS panel indicator, only the LPS indicator flashes, and the other lights do not works.According to the working principle diagram of APS, LPS is the preparation indicator light of APS, which should be in the long and bright state.Flashing indicates that the machine is in a protected state.Test the voltage at each connection from the motherboard of the machine, and the voltage deviates from the normal value, so that the lock fault is caused by APS's failure to start vibration normally.Replace the APS, and the machine is in normal use.

GE LOGIQ P6 fault repair case 1

Failure phenomenon

All probes on the GE LOGIQ P6 machine interfere with the color Doppler mode of operation.

Failure Analysis and Troubleshooting

LOGIQ P6 machine plate structure is simple, plate function integration is high, the color Doppler processing function of this machine is on SYSCOM motherboard, generally this kind of interference considers the probe itself failure, external interference or SYSCOM motherboard and APS power supply.
Since all probes of the machine have interference, all probes are unlikely to fail, so consider other faults first. Pushing the machine to another floor room for testing still has interference problems and eliminates external interference. APS power failure may cause interference to the machine's access voltage. It may be possible to eliminate the APS power failure after the replacement test. Finally, the SYSCOM motherboard was replaced, the machine started to work normally, and all the probes entered the color Doppler working mode without any interference, and the fault was eliminated.

Hitachi EUB-5500 Maintenance

Failure phenomenon

The machine can't start normally. After booting, the progress bar goes to 1/3 and is executed. After shutting down, the same fault still occurs when the machine restarts.

Fault analysis

Hitachi EUB-5500 starts normally after opening the circuit breaker switch and pressing the boot button, the background indicator light of the control panel lights up, the display displays the reading progress bar, after the reading process of the progress bar is completed, the information that the system is starting will be displayed, and then the "Now setting system data. Please wait" start-up surface will appear, and then the ultrasonic system will enter the freezing state of two-dimensional mode after starting.
When the machine goes to 1/3 of the time bar after booting, it can be inferred that the failure of the machine system or PC part results in the phenomenon of machine crash. Firstly, the machine is rebuilt and then tested. After starting the machine, it shows that the reading progress bar is still 1/3 of the machine dead, eliminating the possibility of machine system failure. Hitachi EUB-5500 machine PC part motherboard, MAP board and PB2 board failures may lead to machine startup crash. After re-plugging the MAP board and PB2 board, start-up test, the same crash failure still occurs, eliminating the possibility of bad plate contact failure.

Troubleshooting

After repalcing the main board one by one, the MAP board, PB2 board and the main board are tested. After replacing the main board, the machine starts up nomally and enters the two-dimensional working interface of ultrasound. The machine restarts several times and runs normally, and the machine troubleshoots are eliminated.

Maintenance Cases of Medison

The fault phenomenon
The color Doppler machine of SONOACE X6 operates normally, but there is no display in the image area after entering the working interface of the ultrasound.

Failure analysis
Remove the SONOACE X6 probe interface board and observe that the internal structure of the machine consists of only three plates, namely FE plate, BE plate and POWER plate. Since the probe has normal working sound after the normal start-up of the machine, and the two probes of the machine have no image display, first of all, the probes interface board and the probes themselves can be eliminated, the machine color mode and PW mode can be turned on, and the image area of the machine can display the working mode normally, eliminating the possibilities of the failure of the back part of the ultrasound, that is, the BE plate. At this time, the faults may concentrate on FE and POWER boards. The function of the front-end part of the machine is focused on FE boards, while POWER boards are responsible for the normal output of each voltage. The same faults still occur when replacing the POWER board testing machine. Finally, the FE board problem is determined.

Testing and repairing:
Replacement of FE board.

Philips CX30 system maintenance 
 
The phenomenon of failure:
 The system is properly starting-up, but it will crash during use.

Failure analysis:
Crashing is mainly failure of main board, and the stuck interface prompts the discovery of a new keyboard. This may be a system driver failure resulting in incompatibility or a short circuit in the numeric keypad.
Reinstall the system, the fault remains the same, consider the numeric keypad failure, but the same problem occurs when disconnecting it from the control panel. This fault occurs only when users uses panel keys, then it is suspected that there is a short circuit in the control panel part. So it needs further testing.
The ultrasound machine uses Windows XP system, then using a keyboard test software of the system can accurately detect whether the keyboard has any problems.
Even if the the numeric keypad and the control panel is disconnected, the failure is the same. So it can be determined that the fault is caused by the short circuit of the panel, which continuously triggers the system crash caused by the numeric keypad.
 
Third, testing and repair
Replace the control panel and the machine will return to normal.

PHILIPS HDI5000 color ultrasonic

The phenomenon of failure:
HDI5000 machine occasionally sends 0002 error when starting up, and there is no echo in the ultrasonic image area when the fault occurs.

Failure analysis:
Detailed information of machine error reporting shows FEC error. According to the list of HDI5000 machine error diagnosis, 0002 represents the front-end plate fault, which may be the fault of PSM power board, AIM board, FEC board or CB board.The reason why the machine has no image display is generally that there is a fault in the high-voltage output of the machine, which is generally caused by the PSM power board or AIM board. After replacing the PSM power board and AIM board, the machine still occasionally reports an error of 0002, and the possibility of failure of the PSM power board and AIM board is excluded.Considering the occasional failure of the machine, the CB board may also be out of order. Since there are 8 CB boards in total, they need to be eliminated one by one. Judging from the logic, if the CB board is still out of order after starting up, the CB board may be out of order.

Testing and repair:
After replacing CB board (A9F), the machine starts up and returns to normal use.

Fault phenomenon
After power on, the main display indicates that the system cannot be entered, and then there is an error message in the progress bar, indicating that the system needs to be shut down, and then the black screen automatically crashes.

Fault analysis
The vivid E9& host hardware mainly consists of the following four parts:
a. Main power supply: provide power supply for the whole machine;
b. Back end processing system: system control and ultrasonic image processing;
c. Front end processing system: ultrasonic generation and reception;
d. Console: (keyboard, touch screen and display).
According to the fault performance, it is caused by the communication failure of front and rear terminals, and there are several possibilities as follows:
(1) The main board of the host back-end processing system fails;
(2) Output circuit fault of main power supply;
(3) Communication control board failure of front-end processing system;
(4) The front and rear connecting lines are faulty.

Troubleshooting
First of all, start from the simple point: connect the front and rear ends, pull and plug in the fastening connecting lines, and restart can be successful. At the initial stage, I thought that the fault had been solved. As a result, the machine broke down again after several days of use, and the fault was even more serious. After the machine was turned on, the main display had no image display. Check the back-end main board, and the CPU fan stopped running after several times. Make sure that the main board did not get up, check the back-end power indicator, and the input voltage indicator was normal. Based on the previous faults, it is judged that the main board at the back end of the host is faulty.
Replace the main board of the back-end processing system, and solve the problem.

Fault phenomenon
There are no obvious interference or problem images when examining the patient, but occasionally the image will feel like snowflakes drifting, and there will be small areas of snowflake interference when using the keyboard.

Fault analysis&Troubleshooting
First check the keyboard USB input voltage, measure the voltage is normal, there is no obvious voltage change, and the shell is not charged. Test DCDC output voltage is normal. When I checked again, I found that the keyboard popped up not smoothly and smoothly. Raised the console, and found a problem: the ground wire under the keyboard got stuck in the slideway, and it was found that the exposed metal wire of the ground wire touched a metal object, there would be interference. This ground is a protective ground. Grounding is to protect the earth leakage of electrical components when the skin is damaged. It has a certain protective effect.
When the cable was reconnected to the grounding slot, the failure did not occur again.

GE Voluson E8 no display at boot

Fault phenomenon
There is no display after booting, and an error will appear on the touch screen after a period of time.

Fault analysis
The RTV pointed to by the error belongs to the video management board. The failure of this board may indeed cause the machine to boot without display, but the failure remains after the replacement. First eliminate the possibility of the board failure.

The display function of the machine is mainly managed by the graphics card and the RTV board. Observing the output of the PC chassis line shows that after the machine is started, the image signal should be transmitted to the RTV through the graphics card, and then transmitted to the display and touch screen display.

After troubleshooting the RTV board, the graphics card is most likely to fail, and the machine will be accompanied by an alarm sound when the machine is turned on. Generally, this situation occurs only when a hardware failure is detected during the startup of the PC chassis.

After unplugging the video card, connect the DVI image transmission line of the machine directly to the DVI output port of the motherboard. After the machine starts, there is no alarm sound and the display has image display output, so it can be determined that the graphics card is faulty.

Troubleshooting
Replace the video card and the machine resumes normal operation.

Philips IU22 ultrasonic alarm is lifted

Fault phenomenon
The alarm dialog box appears about 10 minutes after the Philips IU22 ultrasound device is started: 
"System temperature alert.The system has reached a crifical temperature limit, and will power down automatically in 30 minutes.Please check the system air filters before contacting TechnicalSupport.Press OK to power down the system immediately. DiagCode:001"
The operating doctor usually clicks the "continue" button to continue to use, but the system will automatically shut down after 30 minutes, and the alarm prompt will continue to appear after restarting.

Fault analysis and Troubleshooting
The alarm is that the internal temperature sensor of the device detects that the temperature is too high, and the information of the operator of the device is fed back through the computer, and the device protects itself. The possible causes of such failures are clogged air filters, aging or damaged cooling fans, and temperature sensor failures, among which the probability of failure of the temperature sensor is the smallest.
First adopt the conventional processing method, take out the filter on the lower left of the machine, and find that the filter has a serious accumulation of dust. After booting and using, it is found that the system still displays an alarm prompt, and the system will automatically shut down when the time is up.
Walking to the back of the machine, the temperature is obviously increased, and the back cover of the machine feels hot. After turning off the machine, open the back cover of the machine, observe the internal panel, and find that there is very little dust accumulation. After turning on the machine again, check the cooling fan at the rear of the device. All five fans are rotating. Enter the temperature and voltage utility interface, and see that the return values of other temperature sensors are all 30 ~ 55 degree, but the temperature of the right graphics card is 94 degree. The reason for the failure is that the graphics card fan is aging, the necessary speed is not reached, and the insufficient heat dissipation capacity leads to high temperature Alarm, the device runs normally after replacing the fan.

Summary
The maintenance of ultrasonic equipment must first learn to analyze the error report information, analyze and locate the fault according to the specific description of the information and the error code, and then troubleshoot the fault according to the order from easy to difficult, from outside to inside. The inspection room of the ultrasonic equipment is required to maintain a certain temperature, humidity and cleanliness, and the filter screen should be cleaned regularly. It should be noted that the cleaning period of the filter screen should be appropriately shortened in the dry season.

Troubleshooting of GE LOGIQ series ultrasound system
 

Fault phenomenon:
The fault will occur during the first start-up in the morning. The start-up of the machine is in a normal state, and the probe can be effectively switched, and then the fault will occur. At this time, the clipboard of the machine will become larger, and the run key and set key at the lower right of the display will flash.

In this case, the buttons and the touch screen have failed, and pressing the shutdown button will directly pop up the display frame of the system that is not responding. You cannot use the mouse or the touch screen to select. You can only use the left and right buttons to complete the selection. Among them, the restart cannot be chose, and then it will enter the white interface, and there is no response to the forced shutdown. The only measures that can be taken are to unplug the power, and after restarting, the machine returns to normal.

Analysis and Troubleshooting
Copy out the error log in time and enter the CSD for testing. The result shows that it passes. Afterwards, the corresponding inspection of the front and rear connection cables and the hardware of plugging and unplugging the front and rear ends is carried out, and the backup software and settings are also included, and the touch screen and the trackball are replaced.

Observation and research on the error log can find that many of the trackballs and touch screens have faults, and find the relevant logs according to the time when the fault occurs. However, there is no error record in the process of failure.

Through the verification of the fault time point, it can be found that there are many contents related to the information of Tr-ballBut and TouchPush. Then, combined with the flashing problem of the run key and set key at the lower right of the display when a fault occurs, the fault location can be found out. The machine will crash itself in the process of responding to the trackball and Touchpanel, but it is not used as an error in the error log, so the trackball and touch screen can be replaced to solve the machine's faults.

Using manual analysis of the OPPanel schematic diagram, we can understand that the touch screen and trackball have been connected to the USBHub of the Maincon-trol board in the operation panel, so we can understand that the main cause of the failure is damage.
Troubleshooting of GE Vivid 7 crashes


Fault phenomenon
GE VIVID7 color ultrasound equipment crashed twice within 2 weeks, but it was normal after restarting, and it completely crashed on Monday in the third week.
Error reported at startup: DolphUI (0x490): ACQ-SRC: RFT download ing failed!
After displaying the Windows XP interface, an error is reported and the sound window cannot be entered.

Troubleshooting 
First of all, it is suspected that the system files are lost. After reinstalling the system, the failure remains. Then replace the hard disk, install with a new hard disk, enter the fifth bar of the progress bar when restarting to the Windows 2000 interface, and die. Restarting the system installation can continue, but the system files cannot be installed completely. After the hard disk is replaced with the same device, the installation is completed automatically, and the device starts normally, eliminating the hard disk failure.

Now that ultrasound technology is relatively mature, most manufacturers design ultrasound equipment into a front-end probe receiving and transmitting part and a back-end image processing part. RFT is the communication board between the front-end and back-end. According to the fault prompt, it is presumed to be a front-end and back-end communication failure of the device. If the RFT communication board is replaced with the same device, the fault remains unchanged, so it is determined to be a back-end PC motherboard failure.

After replacing the RFT board of the original device, the error report changes as follows:
DolphShell.exe has generated errors and will be closed bywindows. You will need to restart the program. An error log is being created.

After replacing the VGA (Video Capture Card, hard disk module), the failure remains unchanged, and after replacing the power supply, the failure remains unchanged, so the main board failure is judged.

Because the front-end and back-end communications are serial links, start with serial communications. The back-end computer has the same serial port structure as the desktop computer for office use. When the serial port of the computer is normal, its 17 feet should be level-free. If you remove the three insurances of the parallel port and there is no level, you should suspect it is a serial management chip The problem. After replacing the serial port management chip GD75232, the fault is resolved and the device returns to normal.

 
GE Vivid 7 Failure to boot Troubleshooting


Fault phenomenon
The GE Vivid7 color Doppler ultrasound diagnostic system is used as an example. After the device is turned on normally for about half an hour, the screen goes blank momentarily, and there is no response after turning on the device.

Fault analysis and Troubleshooting
The first step is to check the color Doppler ultrasound diagnostic instrument connected to the AC 220V power supply and the AC fuse. If there is no abnormality, eliminate the fault caused by the input part;

The second step is to open the case cover of the color Doppler ultrasound diagnostic instrument. It can be seen that the circuit boards in the case are arranged in a compact manner, and a large amount of dust is attached to the surface of the circuit board. After the dust removal treatment of the circuit board, the experimental boot test shows that the color The Doppler ultrasound diagnostic instrument starts to return to normal, and all functions can be operated normally, but the color Doppler ultrasound diagnostic instrument shuts down again and the black screen cannot be turned on again after about 0.5h after startup, and the fault phenomenon is exactly the same as before;

In the third step, the observation shows that the CPU cooling fan of the color Doppler ultrasound diagnostic system cannot run normally. After the shutdown, the cooling fan is directly replaced, and the failure is finally eliminated, indicating that the failure is caused by the failure of the CPU cooling fan.

Summary 
In the practical application of color Doppler ultrasound diagnostic equipment, there are many reasons that cause the CPU to overheat. In addition to damage to the cooling fan, it may also be caused by factors such as too compact device design and accumulation of dust on the surface of the circuit board.

In addition to the need to replace the damaged cooling fan in time to help the color Doppler ultrasound system to reduce the temperature during operation, the maintenance personnel should also carry out dedusting and maintenance on the equipment regularly to ensure the safe and reliable operation of the system.

Philips EPIQ 7 system reports error "511"

Failure phenomenon
The Philips EPIQ 7 Ultrasound was suddenly powered off during use, and then suddenly powered off after it was powered on. After encountering two sudden power failures, it turned on again. An abnormal startup failure occurred. The display stayed on the "PHILIPS" interface for a long time, and finally entered the boot interface. Error "511" is reported, and the device cannot be used normally.

Failure analysis and Trouble shooting
According to the description of the operator, re-plug the main power cord of the EPIQ7 ultrasound and press the power button to turn it on. It is found that the interface that the display stays on for a long time is the BIOS detection interface (see the figure below). Restart into the BIOS interface and check that the BIOS settings do not appear The problem, according to the BIOS test, is only for the self-test of the front end of the EPIQ7 when it is turned on. Therefore, if there is a problem with the front end of the device, it is suspected that the fault should occur outside the front end.

Unplug the ACQ and power REG PCB from the back-end PC, remove all the front-end load, and leave only the PC part. It is found that the fault remains, and it is determined that the fault should lie in the PC part.

Enter the boot interface and report the error "511", check the error log and find the message "Plantform Monitor failed to start the Digital Media Manger process", which means that some components have failed to start, so it is necessary to find the failed components to determine whether it is the root cause of the failure.

Remove all the circuit boards and cables connected to the PC motherboard, leaving only the hard disk, memory and graphics card. After restarting the EPIQ7 ultrasound, it was found that the BIOS detection interface was quickly completed, and the system was turned on normally without an error, and the fault was eliminated.

It is judged that the damaged parts are among the parts that were just removed. Insert the parts that were just removed one by one each time and then restart the device. It was found that the fault recurred after the DVD cable was plugged into the motherboard. The fault still exists after replacing the DVD cable. The DVD damage caused the EPIQ7 failure. After replacing the DVD, the EPIQ7 is normal, and it can be used again.

Philips HD15 Ultrasound System Troubleshooting 

Faults phenomenon
The HD15 ultrasound cannot be turned on. After pressing the power button, HD15 cannot start normally. Check the equipment failure, and find that the host starts and then stops when starting up, and the display is blank.

Troubleshooting
First check the power supply, the wall socket voltage is normal, and the voltage entering the main power supply of the device is also normal. Make sure that the fault lies in the HD15 device itself.

The power supply principle of HD15 is that AC current passes through the main power supply of the equipment and then enters the ATX power supply at the back end. After the ATX power supply receives the power-on signal, it passes the electricity to the PC motherboard, and the PC motherboard passes the electricity to the back-end ACB circuit through the front and rear interface boards and cables. Then the ACB circuit board will transmit the trigger signal back to the main power supply. After the main power supply receives the trigger signal, the display and the front end are finally activated, and the entire device can operate normally.

According to the power supply principle of HD15, the ATX power supply at the back end starts normally after booting, but it stops and the display is black. It is judged that the device has not been fully started. At this time, the problems of ATX power supply and trigger signal switch can be ruled out. Consider the following problems. aspect:
① The interface board and connection of the back-end PC are faulty;
② There is a problem with the front-end circuit board, and the trigger signal cannot be transmitted to the main power supply;
③ The main power supply and accessories are problematic, and the trigger signal cannot trigger the main power supply.

Check that the interface board and wiring are normal, no looseness or damage; connect the NPOWER ON pin on the front circuit board to the metal casing of the device, force the power supply to operate, and the fault still exists.

After troubleshooting the first two problems, it was determined that the fault should lie in the main power supply and accessories. Therefore, the main power supply of the HD15 device was disassembled, and the appearance of the components on the power board was carefully checked. At this time, a slight bulging phenomenon was found in a capacitor It is suspected that the capacitor is the cause of the failure. After removing the capacitor and measuring with a multimeter, it is found that the capacitor is abnormally charged and discharged. After replacing the capacitor with the same specification and re-welding, the test main power supply is normal, and the equipment failure is repaired.
Philips IU22 cannot start after ultrasonic power off
 

Fault phenomenon
Philips IU22 Ultrasound crashes during use and cannot be started after a power outage.

The operation staff of the department reported that the system crashed during use of IU22 at first, and the system crashed after being shut down and waited for 20 minutes. After a period of use, the system crashed again. The cycle repeats. After a sudden power failure occurs when the system crashes The device cannot be started.

Troubleshooting
The IU22 ultrasound cannot be started. First consider whether the power supply is normal, so first check that the input voltage 220 V, AC, and the stabilized power supply line are normal, and eliminate the abnormal power supply.

Because the IU22 ultrasound encounters a short power failure during the crash, it is suspected that the power failure may cause the IU22 to enter the over-voltage protection state, so the capacitor voltage is released after the power failure, and then the power is turned on again for testing. The IU22 resumes and starts but stays The “Loading” interface cannot enter the system. Contact the manufacturer’s engineer to suspect that the system file is lost due to the power failure. It is recommended to reinstall the system, find the local system CD and reinstall the system, and the IU22 will start normally.
Considering that the operator has reported repeated crashes, based on previous maintenance experience and the description of the operator, it is suspected that the IU22 ultrasound has poor heat dissipation, causing the phenomenon to reciprocate. Therefore, the casing is removed and it is found that dust has indeed accumulated in the casing. Then, clean the fan, remove the dust, clean the filter, and dry the filter. After installation, the IU22 starts normally, and observes the later use process. No system crashes during use. So far, the fault is repaired.
Repair case: Philips IU22 screen flickering

Failure phenomenon
The screen of the Philips IU22 color Doppler ultrasound device is blurred and there are black vertical lines, and the fault still exists after multiple restarts.

Failure analysis
The screen position covers the scanning fan-shaped area of ​​Philips color Doppler ultrasound, so it is speculated that the reasons include the following aspects:
First, the display fails.
Second, the PC graphics card is faulty.
Third, the video conversion board is faulty.

Troubleshooting
First, verify whether the display is malfunctioning. The result of using the monitor shows the same failure, so the monitor problem can be eliminated.

Second, verify whether there is a problem with the video conversion board. If you use VGA to connect to the workstation, if there is still a problem with the screen, you can troubleshoot the converter board.

Third, determine whether there is a problem with the PC graphics card. Remove the color Doppler ultrasound PC graphics card of the same model and install it on the faulty machine. As a result, the fault disappears and it can be determined that there is a graphics card problem.

The color Doppler ultrasound PC host is a special customized component. The graphics card is different from the commonly used computer, and it is difficult to buy similar products in the market. By observing the surface of the graphics card, it is found that the capacitor is swollen. After replacing the capacitor, troubleshoot the problem.

GE Vivid E9 Ultrasound Monitor Fuzzy Screen

Fault phenomenon
After powering on, the system boots normally, but the main monitor displays abnormally, and there is a blurring phenomenon. The system can start to the ultrasound application interface, the touch screen display is normal, and all the functions of the operation interface are normal.

Failure analysis and Troubleshooting
(1) Determine whether the display signal is normal. Check the workstation connected to the machine, the collected images are displayed normally, and the display signal problem is eliminated. It can be judged that the video signal output from the back end is normal.
(2) Confirm whether the DVI cable from the back end to the monitor is normal. Unplug the DVI cable from the monitor and plug it into the monitor of the workstation, the image is displayed normally. Troubleshoot the DVI cable.
(3) It can be judged that the display is abnormal due to its own failure
(4) Check whether the power supply of the monitor is normal. Disassemble the outer frame of the monitor and check the power supply line of the monitor. After measurement, 48Vdc and 12Vdc are normal.
(5) Eliminate the power supply failure of the display. Check whether the chip is damaged or the drive cable is not in bad contact. The latter is easy to operate and has a greater possibility. Since the machine has only been used for 2 years, the possibility of chip damage is small, so first open the display case and re-plug the LVDS Arrange the cables to eliminate signal cable problems. Re-plug the 4 sets of drive cables, each set of drive cables are 40 lines, the wiring is tight, a slight deviation will be out of adjustment.
If the locking ability of the 40-pin interface lock is not good, it may cause frequent display screens.

After repeated adjustments to the cables and interface tightening, the fault is eliminated.




 



GE Voluson E8 blue screen and file loss
 

Fault phenomenon
The machine has a blue screen, reporting that the system file is missing, and it is resolved after reinstalling the system, but this failure recurs after a week.

Troubleshooting
According to the description, reinstalling the system once solved the failure, indicating that it was caused by the computer system software crash, but the same failure occurred one week after it returned to normal. It is suspected that the hard disk may have bad sectors, causing the system files to be lost during startup. Open the panel, remove the hard disk, find a hard disk with the same capacity, and use Ghost to clone a hard disk with the operating system and ultrasound application software using the hard disk engraving method to complete the hard disk replacement and troubleshooting.

Summary
Most medical equipment now uses the Windows platform. The advantage is that it saves manufacturers the cost of developing software and hardware. The disadvantage is that ultrasound system software failures, such as system crashes, occur from time to time. Therefore, at the beginning of the equipment installation, you can consider doing a hard disk clone backup to prevent problems. Once the software fails, you can directly replace the hard disk to ensure the normal operation of the equipment, which not only speeds up the repair speed, but also saves the maintenance cost for the hospital. But pay attention to whether the Ghost version and the original device hard disk use data encryption technology, so as not to cause backup failure, it is recommended to replace the trial after backup to determine the result.
GE Vivid E9 ultrasound automatic shutdown

Failure phenomenon
When the Vivid E9 cardiac ultrasound system is in normal use, it suddenly shuts down automatically. After rebooting, the same situation occurred again after some time.

Fault analysis and troubleshooting
When the machine can be turned on and run, use a USB flash drive to copy the log (data that records the operating state of the device), and search for "shutdown" in the logfile (data file that records the operating state of the device), and find the description of the abnormality of the machine. The shutdown statement "DRX3_TOP=81 is greater than the upper limit 80" indicates that the temperature tested by the DRX sensor is greater than the upper limit, and then from the logfile-TempMon (data file that records the operating status of the device), compared to the same time, it is found that DRX3_TOP has Reaching 81 three times indicates that the temperature value exceeds the upper limit, causing the machine to automatically shut down. Analyze the cause of the alarm: it may be the internal temperature is too high or the DRX sensor is damaged.

Based on the principle of easy maintenance first, the first consideration is that the filter at the rear of the machine is clogged with dust, which makes air flow difficult and heat dissipation is difficult, resulting in excessive internal temperature of the machine and automatic shutdown. Turn off the machine, disconnect the power supply, take out the filter under the machine and the filter sponge at the back of the machine. It is found that there is not much dust accumulation. Observe the environment where the machine is placed again. The room is small but well ventilated. Open the cover on the right side of the machine, pull out the fan under the machine, and find serious accumulation of dust, immediately clean it and dry it. After cleaning, connect the machine power, press the power button to start the machine, the machine runs normally. After a week of observation, the machine did not automatically shut down again, and the fault was eliminated.

Summary
In this maintenance diagnosis, many faults in the operation of the machine can be found through the log to help determine the cause of the machine failure. When analyzing the temperature and voltage logfile, you can import the Txt file into the Excel table for analysis, which is convenient for clear query of the fault statement, making the analysis process extremely convenient. This failure is caused by the accumulation of dust on the cooling fan, which leads to poor cooling of the machine. Therefore, in the daily maintenance process, not only pay attention to cleaning the dust on the filter, but also pay attention to the dust cleaning of the cooling fan. In normal work, we must do a good job The formulation and implementation of daily maintenance and preventive maintenance (PM) plans can not only reduce the equipment failure rate, but also increase the equipment utilization rate more effectively.
GE LOGIQ E Portable Ultrasound Common Failure
 

Failt phenomenon
The GE LOGIQ e mainframe automatically shuts down after only half of the startup.

Fault analysis and troubleshooting
According to the fault phenomenon, first check the power supply battery voltage of the host, there is 12 V, and then measure the current, and find that the current is obviously insufficient. Therefore, it is judged that the host computer is turned off automatically after only half of the power on due to insufficient battery power. Then judge whether the charger of the machine is normal according to the phenomenon of insufficient battery power supply. When measuring the charger, it is found that there is no output voltage. Because the machine can only be powered by the battery inside the machine when in use. Therefore, based on the above phenomena, it is judged that the main reason is the problem of the charger. After replacing the charger with a new one (there is currently no substitute product on the market, you can only purchase it from the factory at a price of more than nine thousand yuan) and then troubleshoot. In the past three years of use, the charger and a battery have been replaced twice.

Summary
Due to the large number of inpatients in our hospital, bedside color Doppler ultrasound examinations are also more frequent, and the operating physicians are often taken off for examinations as soon as they are charged. This mode of operation has a great impact on the service life of the host battery. At the same time, frequent plugging and unplugging of the charger is also one of the reasons for its damage. Therefore, it is recommended to pay special attention to methods and methods in use to avoid unnecessary losses.
GE LOGIQ E9 ultrasound machine frequent crashes

Failure phenomenon
GE LOGIQ E9 color Doppler ultrasound frequently crashes after turning on.

Failure analysis
This fault is a startup fault. First, it is necessary to determine whether the fault is at the front or back end of the system.

Open the BEP shell, turn it on, and find that the rear power indicator shows the following: PS-ON and 5 V stdby LED indicators are on, other indicators are off. It can be seen that +5 V STB has output and PS-ON has action, but there is no +48 V voltage directly output by the main power supply. The reasons for this phenomenon may be:
1. The main power supply fails;
2. The +48 V load has an overcurrent short-circuit phenomenon.

After disconnecting the +48 V load, the fault remains. It is judged that the fault is caused by poor main power supply. For further confirmation, after the main power supply was removed and tested separately, it was found that the main power supply was damaged and there was no +48 V output. After replacement, the fault was eliminated.

GE Voluson E8 scan area without image
 

Failure phenomenon
After the GE Voluson E8 color Doppler ultrasound is turned on, it can enter the ultrasound system normally, and can perform operations such as probe switching, but there is no image in the scanning area, and ultrasound inspection cannot be performed.

Failure analysis
According to the above failure phenomenon, only the image is abnormal, indicating that there is no problem with the back-end startup. It is speculated that the failure occurred in the system file damage, the front end or the probe part. This faulty device is Voluson E8 of BT15 version, so the front-end failure generally occurs in the transmitter and receiver board and the probe connection Board, RFM board.

In this case, there is a problem with the entire image. Follow the principle from simple to difficult. First, connect another probe of the same model that is used normally to the device, and the fault remains. Remove the probe fault.

After reinstalling the system, the fault still remains unresolved. In this fault, the probe can be switched normally, so eliminate the fault of the probe connection board.

BT15 version Voluson E8 is an integrated transmitter-receiver board. If it is damaged, there will be no image in the entire scanning area, so the transmitter-receiver failure cannot be ruled out.

Finally, there is RFM. This board is not only responsible for the front and rear connections, but also for signal digital-to-analog conversion. Therefore, it is suspected that the RFM board or the transmitter-receiver board is faulty, so it is decided to replug the two boards.

Then open the front end, you can smell a scorching smell the moment you open it, then remove the transmitter-receiver board and RFM for careful inspection. At this time, it is found that there is a short circuit in the RFM , and the appearance of the transmitter-receiver board is not found The problem, so it is determined that the RFM board is short-circuited and burned.

Summary
When all the probes have no scanned images, most of them are caused by signal processing and transmission failures. RFM is the focus of troubleshooting. If there is no obvious failure, the same version of equipment in the hospital can also be judged by replacing the board.
Hitachi EUB-5500 ultrasound non-image

Failure phenomenon
The Hitachi EUB-5500 ultrasound equipment is turned on normally, but there is only noise and no image in the fan sweep area.

Troubleshooting
Hitachi EUB-5500 Ultrasound uses Windows XP as the system software, and it directly enters the ultrasound application after booting. If the power on is normal, it means that you can enter the operating system; there is noise and no image in the fan sweep area, but the surrounding characters are displayed normally, which means that the ultrasound application is not problematic. Just in case, use the randomly configured system CD and restart it by CD-ROM. The fault is still found, so the software fault is eliminated.

When the fault occurred, a phased array probe (FPA 2.5 MHz) was used. At the same time, the ultrasound was also equipped with another linear array probe (FLA 10 MHz). Switch the probe to a linear array probe. The noise in the fan scan area changed, but it still No image, adjust the gain, no image is seen, considering that the possibility of two probes being broken at the same time is very small, so it is judged that the probe is normal.

At the same time, it was found that when the probe was switched, no buzzing sound was heard when the probe crystal started to vibrate, indicating that the ultrasound probe was not activated and no ultrasound was generated. The parts that affect the generation and emission of ultrasound are: probes, channel boards, transmitter boards, front-end control boards and high-voltage power supplies, which need to be eliminated and analyzed one by one.

Exchange the positions of the above two probes, restart, and switch back and forth, find that the fault remains, eliminate the possibility of damage to the probe and channel board; re-plug and unplug the DBF, EPI and other functional boards, no improvement after restarting, eliminate the function The board may be loose; use an oscilloscope to check the transmit pulse trigger signal on the transmitter board, it is normal, and there is no red light on the transmitter board indicator, so it is impossible to determine whether the transmitter board is damaged; check the high-voltage power supply according to the prompts on the power board, and find ± The 80 VDC output is abnormal. The power supply provides power to the transmitter board, causing the transmitter board to fail to generate ultrasonic pulses, so there is no image in the fan scan area.

Take out the power board carefully, open the metal casing, and check with a multimeter. It is found that the fuses of F1 and F2 (250 V) have burst, indicating that the circuit has overcurrent or short circuit. The two high-power tubes responsible for providing ±80 VDC have been short-circuited. Remove the burned high-power tube and check the surrounding circuits carefully. No obvious abnormality is seen. Then replace the power tube and fuse of the same model. The power-on measurement ±80 VDC has been restored. The output of other power sources is normal. Connect the load and restart. It is found that normal image signals can be seen in the fan-scanning area. After burning the machine for 3 hours, the department replied that everything is normal. The fault has been eliminated.

GE LOGIQ E9 ultrasound reports an error when booting

Failure phenomenon

The GE LOGIQ E9 color Doppler ultrasound device reports system error and invalid hardware configuration after turning on. After turning off the error, all the probes cannot be identified and the device cannot work.

Failure analysis

The error message indicates that the hardware has not been recognized. First, the software should be removed by reinstalling the system. After the system is reinstalled, the fault remains.

After comparing the normal log and the failure log, it is found that the microcontroller (microcontroller prototyping system, MPS) is not recognized normally. After unplugging the MPS and BEP communication lines on the input/output (IO) board and replacing the MPS, check the log , It is found that the MPS is still not recognized when the device is started, and the connection line on the MPS is plugged into the public interface on the back of the device and then restored to normal.

Therefore, it is judged that there is a problem with the J4 interface of the IO board, which causes the communication between MPS and BEP to be interrupted, causing this malfunction.

Troubleshooting

Replace the IO board, the MPS test passes, the IO board test passes, and the device returns to normal.

Repair Case: Philips EPIQ 7C ultrasonic boot abnormal

Failure phenomenon

After the Philips EPIQ 7C ultrasonic diagnostic apparatus is turned on normally, the screen does not light up, the power indicator is normal, the display only lights up the backlight, and the touch screen is normal.

Troubleshooting

Turn off the device and open the back cover of the monitor, check whether the cable is plugged in tightly, restart the device, and observe whether the monitor can display normally.

At this time, open the back cover of the machine and observe the LED numbers on the motherboard. The display is abnormal. Use a multimeter to measure whether the power supply voltage of the display is 12.5V.

If there is no 12.5V voltage, it means the power supply box is broken and needs to be replaced. If there is a 12.5V voltage, the next step is to connect an external display.

If it can display normally, the display is broken. . If it is not displayed, it can be preliminarily judged that the UAVIO board (audio input and output board) is broken. The UAVIO board is a standard audio and video input and output board with a voltage of +12V. Replace the UAVIO board to solve the problem.

Repair case: Philips EPIQ 7C long startup time

Failure phenomenon

The Philips EPIQ 7C ultrasound device randomly stops at the Philips logo after it is turned on. The stopping time varies, sometimes more than 5 minutes, sometimes more than 10 minutes or longer, and then continue to start. After the start, the control panel is available and the machine works normally.

Fault analysis and troubleshooting

Philips EPIQ 7C models will initialize peripherals during the boot process, and problems with peripherals or cables will cause the boot to slow down.

EPIQ 7C machine peripherals include control panel, hard disk, optical drive, back-end display module, display screen, ECG (electrocardiogram module), etc. The initialization of the interface such as the display screen and ECG does not operate the device, but only initializes the controller, which generally does not slow down.

The back-end display module is connected through the COME module. The board-to-board connection is less likely to have problems. At the same time, the normal output of the picture after startup also shows that the connection has no problem. The control panel, hard disk, and CD-ROM are all connected via cables. Problems with the cables or equipment may slow down the boot.

First, the control panel can be used normally after it is turned on, so the probability of problems is small.

Secondly, the hard disk and the connection line have experienced speed drops. There will be some sudden freezes during the reading process, and the reading speed suddenly drops. In order to solve the problem in the speed drop phenomenon, it has been replaced, but the boot timeout failure phenomenon It still exists, so it can be ruled out.

The only thing left is the optical drive and the connection cable. Unplug the DVD signal cable from the machine, and the machine's boot speed returns to normal. Confirm that the DVD drive cable causes the boot to slow down.

After taking the removed cable to another machine for testing, it is confirmed that the problem is with the cable. The client should be the fault caused by poor contact caused by the bending of the cable.

Therefore, if you encounter such problems on the client side, you can consider disconnecting or replacing the peripherals one by one to test, and locate the problem to quickly solve the problem.

Repair case: Philips EPIQ 7C Transmitting Board

Fail phenomenon

After using the Philips EPIQ 7C ultrasound device for a period of time, bright areas appear in the echo area. It was normal after the transmitter board was replaced on site, but it reappeared after a day. A similar problem occurred before. After swapping the transmitter board, it was confirmed that the transmitter board or the receiver board was the problem. However, the problem may occur again after 1-2 months of normal use after replacement. Kind of problem. Changing the launch board several times still failed to completely solve the problem.

Fault analysis and troubleshooting

After research and analysis, it is judged that the transmitter board may be burnt due to the probe itself. Therefore, when the problem occurs again after replacement, the probe (usually used for a period of time) needs to be measured. We can assume that there are several channel impedances in the probe. It is abnormal, short circuit to ground or low impedance, use a multimeter to measure the impedance to ground of the POUT channel in the probe. No need to connect the host, directly measure the independent probe. For the definition of the probe connector, the orange cells are POUT channels, and the yellow cells are ground. Under normal circumstances, the ground impedance of the probe POUT is infinite or megohm (about 35K&Î&©). If it is less than this magnitude, it is considered an abnormal situation.

As a result, the measured resistance value was only tens of ohms. If the electrolytic capacitor in the probe is damaged, there will be no voltage output; or the output voltage is not well filtered, and the circuit will have logic confusion due to voltage instability, which shows that the probe is working well and sometimes badly. Therefore, it can be judged that the probe is damaged. In order to completely solve the fault, we need to replace the transmitter board and the probe at the same time.

Philips EPIQ 7C V6-2 probe artifact troubleshooting

Failure phenomenon

The 2D image of the Philips EPIQ 7C ultrasonic three-dimensional volume probe V6-2 has an artifact on the right side of the center, and the artifact is more obvious after the image is colored.

Troubleshooting

First swap the slots between V6-2 and C5-1, and observe that the image of C5-1 is normal, and the artifacts in the middle right of the image of V6-2 still exist. It is determined that it is not the problem of the slot interface.

Then there may be bubbles in the probe V6-2, select V6-2 for the probe, turn on the 4D mode, let the motor in the probe rotate for a period of time, then switch back to the 2D mode, and hang the probe upside down for a period of time. If there are bubbles, the above two steps are mainly It is to eliminate the bubbles in front of the array element. But image artifacts still exist after the above two steps.Moreover, the artifacts are elongated after painting.

In the end, it may be that an array element in the probe is broken. Freeze the machine. Unplug all the probes and U disk to enter the maintenance service interface and perform probe test under Hardware Utilities. Copy out the test log (log) and analyze it. It is found that there are four elements in the probe damaged. In engineering practice, the energy of a single element is small when it is launched. Generally, multiple elements are combined to transmit, which plays a role in controlling the signal. Next, each array element is grouped and combined and excited in a certain way to form different emission beam scanning. If the array element is damaged, part of the image cannot be scanned.

The device image returned to normal after the probe was replaced, and there was no failure after a period of trial.

GE vivid E9 ultrasound device high temperature alarm

Failure phenomenon

The GE vivid E9 color Doppler ultrasound device initially selects a high temperature alarm during operation, and automatically restarts.

Troubleshooting

The high temperature alarm indicates that the cause of the fault is mainly due to the high internal temperature of the equipment host and the protective restart of the equipment.

Therefore, the maintenance personnel first checked the indoor temperature and found that the indoor temperature was slightly higher than the appropriate temperature for the equipment to operate. After the air conditioner was turned on to lower the indoor temperature, the equipment was turned on again and found that the above-mentioned fault still occurred after the equipment had been running for a period of time.

After troubleshooting the fault caused by the ambient temperature, after repeated inspections of the equipment, the maintenance personnel found that the air filter under and behind the main unit of the equipment was seriously polluted. After cleaning the air filter, restarted the test operation and found that the fault disappeared.

Combined with the actual operating failure of our hospital's GE vivid E9 color Doppler ultrasound diagnostic system, the restart of the equipment due to overheating protection is more common, especially in summer. The environment of the equipment room should be cleaned and the equipment inside the equipment should be cleaned regularly. Each filter should be cleaned or replaced. If the above failure still occurs when the ambient temperature is suitable and the sanitary conditions are qualified, a cooling fan should be installed at the bottom to speed up the heat dissipation of the equipment.

Repair case: Philips IU22 screen flickering

Failure phenomenon

The screen of the Philips IU22 color Doppler ultrasound device is blurred and there are black vertical lines, and the fault still exists after multiple restarts.

Failure analysis

The screen position covers the scanning fan-shaped area of Philips color Doppler ultrasound, so it is speculated that the reasons include the following aspects: First, the display fails. Second, the PC graphics card is faulty. Third, the video conversion board is faulty.

Troubleshooting

First, verify whether the display is malfunctioning. The result of using the monitor shows the same failure, so the monitor problem can be eliminated.

Second, verify whether there is a problem with the video conversion board. If you use VGA to connect to the workstation, if there is still a problem with the screen, you can troubleshoot the converter board.

Third, determine whether there is a problem with the PC graphics card. Remove the color Doppler ultrasound PC graphics card of the same model and install it on the faulty machine.

As a result, the fault disappears and it can be determined that there is a graphics card problem. The color Doppler ultrasound PC host is a special customized component. The graphics card is different from the commonly used computer, and it is difficult to buy similar products in the market. By observing the surface of the graphics card, it is found that the capacitor is swollen. After replacing the capacitor, troubleshoot the problem.

Philips iU22 ultrasound abdominal probe PW mode error

Failure phenomenon

The abdomen probe C5-2 used for Philips iU22 ultrasound equipment is checked in 2D mode, the instrument is normal, when switching to PW mode (pulse Doppler), the instrument reports an error, after restarting the machine, the 2D mode is used normally, and the failure of switching PW mode remains. The superficial probe L11-3 is not affected in any way.

Failure analysis

There may be 3 reasons for this failure: 1. Probe failure. 2. Machine system or software problems. 3. The circuit board is faulty.

Maintenance

Replace with another C5-2 probe that is in normal use and perform the same operation, and the fault remains. Remove the probe fault. Performing the instrument self-check and software self-checking did not find any problems, restore the mirror backup software on the machine, the fault persists, and eliminate the system and software problems. Considering the reason of the circuit board, in the process of PW mode switching in C5-2, a group of high voltages will dynamically change. The front-end NewAnalog Input Module (NAIM) analog voltage modulation board is responsible for providing the front-end 320MHz master clock, providing the pulse voltage for exciting the probe, and adjusting And calibrate the high voltage pulse, also generate TGCI, TGC2 waveforms, check the overcurrent, overvoltage, front-end temperature at the same time, and manage all the front-end power supply, so it is considered that the NAIM board may be damaged. Disassemble the front chassis, pull out the NAIM board and find that the bottom filter mesh is too dusty, indicating that the board has a problem with heat dissipation. Observing the NAIM board, it is found that the R650 resistor that controls the high-voltage dynamic change part has an abnormal appearance. The resistance is measured with a multimeter to determine that the resistor is damaged. Clean and maintain the machine, replace it with a new NAIM board and restart it after resetting, the fault disappears.

9L-D Probe Image Interference Troubleshooting

Failure phenomenon
GE Vivid E9 ultrasound instrument 9L-D probe interferes in color blood flow mode, other probes and imaging modes are normal.

Troubleshooting
First judge whether the probe is faulty, take the probe to another Vivid E9 for testing, and the display is normal.

After excluding the cause of the probe itself, it was suspected to be a use environment problem, and the equipment was moved to another ultrasound clinic to start the test, and the fault disappeared. In order to determine that the fault is caused by the use environment of the equipment, it is necessary to find the source of interference.

Turn off all the electrical equipment in the clinic one by one, and the fault has not disappeared; disconnect the power connections of the electrical equipment in the clinic one by one. When the main plug of the reporting workstation is removed from the power strip, the interference is reduced, and the source of the interference is suspected to be in the workstation A link in the power supply connection.

Continue to disconnect the power outlet of the workstation, and the interference disappears. Repeat the test to confirm that the image interference is caused by the power strip connected to the workstation. Replace the power strip and solve the fault.

GE Vivid E9 cannot enter the system

Failure phenomenon

The GE Vivid E9 color Doppler ultrasound device restarts after booting through the Basic Input Output System (BIOS) self-check interface and cannot enter the system.

Troubleshooting

The abnormal startup of the ultrasound equipment is usually caused by the failure of the computer as the back end of the equipment, such as the damage or poor contact of the memory, hard disk, graphics card, motherboard and other components.

This failure occurred after the device was pushed to the ward for bedside inspection, and it was suspected to be caused by the loosening of the back-end board.

Remove the left side cover of the host, open the rear chassis, re-plug the memory, graphics card, and hard drive in sequence, and then re-plug the S-ATA cable connected to the hard drive and solve the problem.

The ultrasound back-end can be regarded as a powerful PC, and its hardware or software abnormalities often cause the ultrasound equipment to fail to start normally. In use, try to avoid severe vibration of the equipment, maintain good internal cleaning, and reduce the occurrence of hardware failures.

For software failures such as system crashes, it is necessary to fully grasp computer knowledge and learn to use Ghost, U disk boot and other tools to make system backups, so as to solve such failures in a timely and effective manner.

Mindray DC-8 ultrasound: No image in the echo zone of the probe

Failure phenomenon
After the Mindray DC-8 color Doppler ultrasound device is started normally, there is no image in the middle part of the echo area of the probe. After many times of unplugging and plugging the probe and restarting, there is no change in the fault phenomenon, and there is no prompt or error message.

Troubleshooting
According to the failure phenomenon and personal maintenance experience, judge according to the following methods:

First, replace the probe to another slot. If the fault phenomenon is the same as the original one, the fault of the probe slot can be eliminated. Then, check whether there are missing images in other probes. It is found that the image in the middle part of a convex array probe is completely missing, and two parts of the image in a linear array probe are missing. The possibility of simultaneous failure of the two probes is extremely small, and the probe failure can basically be eliminated .

Second, contact the manufacturer&’s engineer to assist in the judgment. According to the failure phenomenon, the image problem may be caused by the failure of the ultrasound transmitter board, the ultrasound receiver board, and the image signal processing board.

However, it is difficult to judge which board card caused the fault. You can use the self-check function of the ultrasonic equipment to perform auxiliary detection and judgment. Click the "Maintenance" item on the "Preset" menu, open the "Maintenance" menu, and click "Self-check" Carry out the self-check of the system, the self-check reports the error of the signal processing board. After replacing the signal processing board, the equipment returns to normal.

Philips EPIQ color Doppler ultrasound crash troubleshooting

Failure phenomenon

The Philips EPIQ 7 color Doppler ultrasound system crashes frequently during use, and it crashes again after 2h after restarting. The machine was purchased for less than half a year. Every time it is turned on, the startup process is completely normal, there is no error message, and there is no error message record in the self-check information database.

Failure analysis
The system crashes during normal use. The possible reasons are:
1. Failure of the PC terminal;
2. Color Doppler ultrasound power failure;
3. Display failure;
4. Signal control module.

Troubleshooting
(1) Check the instrument and eliminate the display failure. The output of the power supply module is normal. When the failure occurs, the status indicators on the PC side are displayed normally. Remove the PC side and connect the external display. The display is normal when the computer is turned on, and the PC side failure is eliminated. Observe the signal control circuit board, the indicator light shows normal.

(2) Observing the fault performance repeatedly, it is found that the fan at the bottom of the color Doppler ultrasound instrument has been buzzing and working after the host is forced to shut down when the host is not shut down. Refer to the operation manual of the device. It is a cooling fan. When the temperature sensor detects that the internal temperature of the color Doppler ultrasound is high, it will work. After shutting down, remove the cover screws and open the back cover and side panel of the machine. It is obvious that the internal temperature of the machine is too high. Therefore, it is judged that poor heat dissipation has caused the protective redundancy of the instrument or the signal control unit to crash after overheating.

Open the bracket around the cooling fan at the bottom and remove the filter. It is found that there is a small amount of dust. After cleaning and drying, it is installed back to the machine and restarted. The fan speed is uniform and normal, and there is no more crash.

GE VOLUSON E8 cannot start

Failure phenomenon
The GE VOLUSON E8 ultrasound power button is on, and the machine has no response when pressing the power button and cannot start.

Troubleshooting
After opening the outer cover of the machine, it is found that there is a lot of dust inside the machine, which is not convenient for maintenance. First, remove the dust from the machine.

There is no response when the device is turned on. It is judged that there may be a problem with the power supply to the main board or a faulty switch button during startup.

It is detected that the mainboard power supply is normal, but the voltage does not change when the power button is pressed. Remove the power button for measurement. When the power button is pressed, it is connected. It is suspected that the power supply to the motherboard is faulty. Replace the power supply. The device still has no response after replacing the power supply part, and troubleshoot the power supply part.

Considering that the main reason for booting may be the failure of the back-end, so I plug in and pull out the board test, leaving only the minimum bootable motherboard, memory, and power supply. You can start the basic input/output system (basicinput/utputsystem, BIOS) and add other board tests one by one. The device does not respond after the main graphics card is started, it is determined that the main graphics card is faulty. After replacing the main graphics card, the device returns to normal, and the fault is eliminated.

GE VIVID E9 ultrasound system automatically restarts and shuts down

Failure phenomenon

After the GE VIVID E9 ultrasound is turned on, the system will automatically restart when the progress bar interface is displayed, and will automatically turn off after repeating twice.

Failure analysis

The system automatically restarts and shuts down automatically, generally due to the following four reasons:

(1) Part of the power supply module is faulty;

(2) Front-end and back-end communication failure;

(3) Front-end circuit board failure;

(4) The back-end load circuit is faulty. Repair process Open the casing of the machine and start the machine. After inspection, it is found that the power module indicator is normal.

In the shutdown state, unplug and fasten the front and rear ends, the communication line and the ground wire circuit breaker (GFI) of the front control panel, and the fault is still found in the startup test operation. However, during the boot process, it was found that the power status lights of the front-end boards were not bright, indicating that the front-end power was abnormal. The analysis may be that a front-end circuit board has an overload fault.

The front-end circuit board was unplugged one by one to start the test run. It was found that after unplugging the control board GFI, the front-end board was powered on normally, and it was judged that the front-end control board GFI had an overload fault. Remove the GFI board and check it carefully.

It is found that a capacitor module on the circuit board has a faint burnt smell. Use a multimeter to measure this part of the capacitor module and find that the capacitor C84 is short-circuited. It is determined that the capacitor burns out and causes voltage overload protection. After replacing this capacitor, install the front-end control board GFI to start the test run, the machine is in normal use, and the fault is eliminated.

GE VOLUSON E10 image is whitish

Failure phenomenon

The scan area image of GE VOLUSON E10 color ultrasound system is whitish, and restarting is invalid.

Troubleshooting

Voluson E10 image problems are common front-end board problems. Diagnose according to the image conditions, replace the RFM board, and troubleshoot after reinstalling the system.

Tips: Poor contact between the various components of the ultrasound equipment is a common cause of failure of the ultrasound system. Dust pollution, contact oxidation, frequent insertion of probes, bumps during use, etc. may all lead to poor contact.

Regular dust removal, regular maintenance and preventive maintenance if possible, avoiding human damage as much as possible is an effective way to reduce the failure of the ultrasound system.

Hitachi Noblus Ultrasonic Startup

Failts phenomenon

The power button of the portable ultrasound is not working.

Troubleshooting

1. According to the fault phenomenon, the power-on button of the device is damaged. The ultrasound power button is an integrated mask unit. Therefore, the entire mask unit needs to be replaced.

2. Remove the cover on the back and remove the circuit boards layer by layer. After the final replacement, the fault is eliminated. Summary The device power-on button fails, and the contact point of the mask is damaged.

GE VOLUSON E8 system troubleshooting

Fault phenomenon

The GE VOLUSON E8 color ultrasound system has a blue screen and reports that the system file is missing. It is resolved after reinstalling the system, but this failure recurs after a week.

Troubleshooting

According to the description, reinstalling the system has solved the fault, indicating that the computer system software crashed, but the same fault occurred a week after it returned to normal. It is suspected that the hard disk may have bad sectors, causing the system file to be lost during startup and causing the fault.

Open the panel, remove the hard disk, find a hard disk with the same capacity, use Ghost to clone a hard disk with the operating system and ultrasound application software using the method of hard disk engraving, complete the hard disk replacement, and troubleshoot.

GE LOGIQ E9 ultrasound workstation has no signal input

Faults phenomenon
The GE LOGIQ E9 color Doppler ultrasound machine is operating normally, and the workstation has no video signal input.

Failure analysis
1. There is no signal connection between the machine and the workstation, and system settings, equipment hardware, and external equipment should be considered. Since this model is a 2017 new model, the system video signal output is automatically modulated without manual setting, so the system setting problem is eliminated. Next, consider the external equipment. The hospital provides a DVI display to connect to the equipment, but it still shows no signal. The display can be received normally on other equipment, so the external equipment problem can be ruled out. The hardware first considers the io board that manages the input and output of the system, and replaces the io board;

2. The signal still cannot be output after replacement. Considering that the video distribution board is faulty, the video distribution board is replaced.

Summary
Replace the video distribution board, the workstation can receive signals normally after booting, and the fault is resolved.

GE LOGIQ E9 reports system error when booting

 

Failure phenomenon

The GE LOGIQ E9 color Doppler ultrasound machine reports a system error when it is turned on.

Troubleshooting

1. Firstly, check the power supply, replace the power supply, restart the machine, and find that the fault is still there. The initial troubleshooting has nothing to do with the power supply.

2. Secondly, detect the MRX board. The MRX board combines DRX, GRX and GFI, and has the function of receiving and processing signals. Replace a tested board on the device, and the failure remains, so the possibility of MRX failure is eliminated.

3. Thirdly, check the GTX board. This board has the function of sending signals. There are three boards on the device. Remove all the three boards. Use a tested GTX board to test the three corresponding interfaces. The result is All system errors are reported. Under normal circumstances, if a GTX board is installed separately, there will only be a missing echo area and no error will be reported. Therefore, the error has nothing to do with GTX.

4. Finally, download the log file to view the error log. It is found that GFI reported an error, and GFI is integrated on the MRX, but MRX has been verified as OK, so considering the insufficient power supply to the PD board powering the MRX, the PD board is replaced and the fault is resolved .

GE LOGIQ S8 BF, control panel failure

Failure phenomenon
The two-dimensional image of the machine is abnormal, and the blood flow is abnormal; the blood flow knob is not sensitive.

Troubleshooting:
According to the above failure phenomenon, it can be judged that the image channel of the machine is abnormal. Therefore, it is suspected that there is a problem with the BF board of the machine, so replace the BF board. After replacing the BF, remove the fault.

Disassembly steps:
1. First, remove the BF board from the back of the machine.
2. Next, replace the BF board with a new one.
3. Then, turn on the machine again, and the image displays normally.
4. It was found that the blood flow knob was not sensitive during the malfunction of the machine, so the control panel of the machine was disassembled and the circuit board where the blood flow button was replaced was performed.

5. Result: After replacing the circuit board where the blood flow button is located, the knob returns to normal.

Repair result
After replacing the BF board and the circuit board where the blood flow button is located, the machine malfunction is resolved.

Hitachi ARIETTA 60 cannot be turned on normally

Failure phenomenon
After the Hitachi ARIETTA 60 machine turned on and displayed the HITACHI logo, the display and touch screen did not display, and the button lights on the control panel flashed cyclically, and the ultrasound interface could not be entered normally.

 

Failure analysis

1. After the machine is turned on, there is no display after the HITACHI logo appears, and the button light on the control panel flashes cyclically, indicating that the power supply of the machine is normal, and the fault is caused by a problem in the back of the machine.

2. The back end of the machine is composed of BE main board, CELL board and system hard disk. On the right side of the machine, you can see it after opening the casing. First, rule out whether the system is faulty. After replacing the system hard disk, the same fault still exists when the machine is turned on, so the BE motherboard fault is locked.

3. Since the BE motherboard is connected to the front-end TPRB and RDBF boards, you need to remove the front-end board first, and disconnect the other power connections of the BE motherboard.

4. After replacing the BE main board, the machine starts up normally, and all the probes and functions are in normal use.

Summary
After replacing the BE motherboard, the machine resumes normal use.
