Greetings:
I am working on a GE Logiq 9. The scanning area has some dark spaces like stripes and seems to have some noise in the image. This problem occurs with all probes. Intermittently, the curved probe like E8c or 3.5 C has some artifacts like white stripes for a few seconds, then disappears. All diagnoses passed but I first replaced the EMB board as a troubleshooting and then I changed the FEPS, but still with the same problem. All FEPS LEDs are on and the EBM board has DS6 and DS7 in red. I changed the entire TD board according to the system diagram to make sure that the device has some change but is still in the same area. Is it normal for the SBC board to have a loud noise when some probes are used?
Thanks in advanced for the help
Have a great day

Permanent Noise on the scanning area

Are the stripes vertical or horizontal? I ask because certain GE scanners, when using certain presets and certain probes, can produce horizontal banding artifacts. Typically, vertical stipes, streaks and dropouts are probe or channel related. If white, shooting artifacts are observed when using the E8c, there may be some fluid invasion. The more info that you can provide, the better diagnosis we all can provide. You can even attach a photo in the area and picture's worth 1000 words.
