Do you have any idea what might have cause this problem? (Lightning, software bug, etc) Also, what have your tried to do to resolve the issue so far? Could you please include pictures of all of the PCB’s inside the tv? I have more experience with Macbook and iPhone board repairs. Sometimes, even if a main power line is present, it doesn’t necessarily mean the right lines are turning on to enable different parts of the board. (CPU, SMC, etc) This is harder to diagnose without schematics but is still possible. Other times, it’s easier/cheaper to buy a new set of logic boards for the TV.
