We have not had a storm today. The unit was working this morning without a noticeable problem.
The system has not shut off before on its own.
There is no response at all. I have pulled out the plug and re-engaged.
Following your instructions above ...there has been no change.
Unfortunately there aren't any resets or adjustments that will allow the set to power up.
There is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets. The problem could also be a cracked solder joint, or failed IC regulator, in which case it would be more cost effective to replace the board itself.
The boards are plug and play, meaning that no soldering is necessary to replace the board. If you'd like to swap out the board, and fix the TV yourself, you can purchase a brand new power supply at the link below to repair your set:
