Panasonic Plasma Power issues

[Runny]

I have a Panasonic TC-P50S2 that was given to me. The TV will work for hours and then shut off, I could unplug for a minute then plug back in to have it shut off again after hours if watching. There is no blinking red light like some of the other post, and no timer settings set. I replaced the power board, and still same problem. Could the replacement board be defective too, or should I look at the y-sus board or main board. I don't see any bulging caps. Is there any post that can show me the proper steps to troubleshoot this issue.

I would tend to think A-board. Could be heat related and they can have BGA solder issues which show up with heat. Probably near impossible to fault find.

I would also think the lack of an error blink code points to the A-board too.

PTS Electronics rebuild boards but may also be tricky for them to do if the fault is not present when they get the board.
