Could it be the ribbon by and chance? Thank for all the support, and just put what board I need and I’ll try and sort something out
@nugget97 so far nothing to spectacular. One are of interest is on the power board. Could just be my old eyes but the caps under the heatsink look a bit discolored and the thermal paste on the FET looks different than the others. Again, could just be my old people vision
Since this only happens in HDMI my first suspect is still the main board. Let me see if I can find anything out about this board.
