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.
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.
Philips IE33 is the world's most advanced ultrasonic diagnostic device for cardiac ultrasound, which can dynamically display the intracardiac structure, heart beat and blood flow. It has a new field of vision to probe the cardiac structure, real-time multi-dimensional imaging and parameter quantification, making diagnosis faster and more accurate.Superior angiography performance, greatly increased color blood flow sensitivity, for the observation of the heart, large vessels, peripheral vessels and viscera vessels pathophysiological changes, known as "non-traumatic angiography".

Troubleshooting
Rebrush the SIP and DSC software and the problem reappears after a few days of normal use.See system error code, prompt DSC problem: prompt message is data refresh timeout.According to this error message, it is suspected to be a fault of DSC, but it needs to be confirmed that this error message is the root cause of the system problem.Check the initial error message and the prompt is not DSC: the problem with this error message is Dolphin's communication. Continue to check the log: the prompt points to Node ID4, the Dolphin board of HOST.Replace the dolphin card and IPL line of HOST, and reinstall the software for troubleshooting.
Fault phenomenon
System error"602"
Troubleshooting
Most of the 602 errors are due to memory: loose connections between memory and slots, or poor contact due to oxidation or dirt on the surface of memory gold fingers.First eliminate 602 errors due to incorrect BIOS memory hole setup (use FII Instruction to verify the hard-ware /Software memory hole setup for the current Software version).After cleaning and refixing the memory, the equipment started normally, troubleshooting.

After that, the phenomenon of image delay appears every day. It will be fine after shutdown and restart, but it will appear again after a long time.
Troubleshooting
Check the fault log, and all the errors point to sip. Focus on troubleshooting sip. First, plug and unplug the PCI wiring of dolphin on SIP, and then plug and unplug the board card on SIP. The fault is still the same. Then swap SIP with host's dolphin, and the fault is still there. After several operations, it was found that the sound of a CPU fan of SIP was sometimes abnormal. After careful observation, it is found that the fan speed is not normal sometimes. Check the log again and select temperature. It is found that the temperature of SIP / CPU is too high to 82 ℃ (normally, it should be around 45 ℃), which results in the decline of SIP processing function and image delay. Replace CPU fan and sip, fan temperature returns to normal, troubleshooting.
Fault phenomenon
The 17-inch LCD monitor is discolored and streaked, but the image displayed on the workstation is normal.
Fault analysis
According to the failure phenomenon, it is judged that the graphics card output of the machine is normal, which is a problem of the display itself. First, save a few pictures, then check the monitor's POWER / USB CABLE and HDMI CABLE, and connect the HDMI CABLE to the external display to find that the displayed image is normal, indicating that the HDMI CABLE is intact and the output signal is normal.
Then, open the back cover of the monitor and reconnect the internal wiring one by one according to the Main 17-inch LCD Monitor Block Diagram.
When touching the flat cable connected to VIDEOCNTL, the image displayed on the monitor is normal. In order to confirm that it was not the occasional accidental recovery of the display, the flat cable was slightly shaken, and the display was discolored and water streaked again, and the fault point was finally determined. The flat cable was originally designed to be directly connected, and now it is fastened with hot melt adhesive after improvement. After the flat cable is fastened, the display image is normal, and the image previously saved on the clipboard is also normal!
Troubleshooting
Use hot-melt adhesive to fasten the flat cable connected to the VIDEO CNTL inside the display, and the fault is resolved.
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.
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.
Philips IU22 ultrasound cannot be turned on
Failure phenomenons:
GE Vivid E9 ultrasound equipment, there is no obvious interference or problem images when examining patients, but occasionally the images will feel like snowflakes drifting, and there will be small areas of snowflake interference when using the keyboard.
Fault analysis:
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.
Raise the operating platform and find that the ground wire under the keyboard is stuck in the slideway, and it is found that the bare metal wire of the ground wire touches the metal object, causing interference. This grounding is a protective grounding, which is different from the general grounding. The protective grounding is a leakage protection grounding to prevent the damage of the surface of electrical components, and it has a certain protective effect.
Troubleshooting:
When the cable was reconnected to the grounding slot, the failure did not occur again.
Fault phenomenon
The screen of Philips IU22 color ultrasound device stays on the scroll bar interface when it is turned on. After 30 s, a dialog box error code 518 appears. You can choose to enter the settings or directly shut down the dialog box below, but you cannot enter the system operation interface. Restarting the device cannot be solved.
Fault analysis and Troubleshooting
Enter the setting interface, use U disk to export the system error log, analyze it by the manufacturer engineer using Philips special software, and determine that there is a problem with the system file. It is recommended to reinstall the system.
Previously, the hard drives removed from scrapped computers and equipment used hard drive burners to make hard drive backups for Philips IU22 and IE33 and other common devices. IU22 has 3 hard drives, labeled HDD0, HDD1 and HDD2, where HDD0 is the system drive, HDD1 and HDD2 realize image storage.
Replace the system hard disk first, and report 602 error after booting. It is analyzed that the codes of the software and sub-hard disks do not match. After the backup HDD1 and HDD2 are replaced, the device boots normally, enters the system operation interface, and tests all functions are normal.
Summary
When conditions permit, it is important to do a good job of backing up equipment systems and data. At the same time, the hard disk of the scrapped equipment can be used to back up the system and data of commonly used ultrasound equipment, which can effectively use resources.
The hard disk capacity of the early ultrasound equipment is mostly 500G, and hard disks above 4T may not be recognized. The backup should be performed with 1T or 500G hard disks.
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.
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.
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.

5. Replace the machine parts according to the instructions and maintenance manual. The filter and sealing ring have been used for about half a year to a year, and should be replaced in time.
6. After the color Doppler ultrasound is fully cleaned and disinfected, it is assembled and corrected, and the tightness of each nozzle is strictly checked. Use a clean cloth to cover the equipment, and affix a sign of standby status. The equipment should be placed in a suitable environment as required for easy use at any time.
7. For equipment that has not been used for more than one month, the equipment should be cleaned completely, the cleaning time should be more than one hour, and the equipment should be tested and tested according to the maintenance manual and instructions to check whether the equipment is operating normally. It must be taken seriously and not perfunctory.
8. Carry out the cleaning of the surface of the equipment, check whether there are stains on the surface, whether the shell is smooth, whether the spin keys and buttons are normal. For equipment packaging and appearance damage, it is necessary to make a record and take photos of the inspector and the acceptance report.
9. According to the contract configuration requirements, carefully check and record the model, name, specification and quantity of the equipment on the packing list. Check whether the performance and quality of the equipment are in good condition. If the model and quantity do not meet the list, make a record and save the original packaging of the equipment to facilitate the request for compensation or replacement by the manufacturer.
In summary, the frequency of use of color Doppler ultrasound is increasing, which increases the probability of color Doppler ultrasound failure. Therefore, it is necessary to do a good job in the daily maintenance and repair of color Doppler ultrasound, comprehensively guarantee the safety and quality of color Doppler ultrasound, ensure the smooth progress of various medical tasks, and improve the treatment effect of patients.
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 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.

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.

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 .
