There are streak artifacts on the image. After troubleshooting, I took the CPU IF, ANGLE and LOGIC, and ADC boards to another Philips CX/S CT scanner to test them. The test showed the bds except the CPU IF and ANGLE & LOGIC were good.If I inserted both CPU IF and ANGLE & Logic bds at the same time, the artifacts appeared. But if I inserted only one of the above two bds, the image is OK. I don't know the reason. So I need help urgently from you. Thanks in advance.
Well does the artifact appear when the original CPU bd is used with a substitute logic bd? If so does it go away if you use the original logic bd and a substitute CPU bd? It is obvious either 1 or both of these bds are bad. Find the problem board(s) and replace them. It is one or the other, or both. Order both of them, pre-owned and ask if you can return one of them if you don't need it? If you need a source for the part contact me and I will see if I can get what you need>> I'll need the p/n's from the boards not only the board name.

This may sound odd but if the speed of the scanner is off you wiil get intermett lines.
run scan test for gantry speed.
good luck
