Hello. I have a Samsung qled model QE58Q60TAU.
The TV restarts continuously and without an image. If I disconnect either half, the TV does not restart, but in both situations I have absolutely nothing on the display, only the backlight is on. I checked the CKv signals and the rest VGH, VSS etc. I measured them against the ground and between them and found between VGH and VSS a resistance of 106 ohms on the B side of the screen (right). I isolated all the signals on the right side and covered them with scotch tape and absolutely nothing has changed, it doesn't restart but I have no picture at all. I also isolated the signals on the other side of the screen but nothing changed. The thing is that I don't have VGH and VSS at all, even if I have those routes covered, basically the screen blocks the voltages on the tcon. I checked if I have any shorted capacitors and I don't. I checked the ESD protection diodes, and I even removed them and still to no avail. On side A I also have a smd 25q32 memory, I was thinking of seeing it too, although I wouldn't believe it. Seeing that I don't have VGH and VSS voltages, I borrowed an identical motherboard but in vain, it's not from here, it's from the display. I don't know what else to do? Thanks.
