@oldturkey03 thanks for the answer. Since the TV was not purchased from an authorized LG dealer, warranty repairs were immediately denied. We opened the lid, but everything is perfect there and there are no signs of corrosion or short circuit. All wires are in place. We tried disconnecting them, inspecting them and reconnecting them, but the problem did not go away. I need a good specialist who can check the hardware or someone who has already encountered a similar problem

@oldturkey03 To the central board, apparently where the processor itself, there are two narrow cables going from the side, those that are numbers EAD63787937, EAD63787882 in the photo, and two wide cables EAD65913002 coming out that are connected at the bottom to the matrix itself. We disconnected and connected the thin ones, the image disappears and appears, but the problem does not go away. If you disconnect the wide ones, the TV turns off abnormally and there are also no changes after connecting. Perhaps you need to check these cables for breaks or the scanner board itself for correct operation? I can’t imagine how this can be done and where to look for competent service in Sacramento.
