Facing TV Problems? Ask a TV Technician.
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. Average cost to have this repaired by a shop is around $250-$275 parts and labor.
However, if you want to repair this yourself, you can save around $200. There is a video that shows you how to replace the Power Supply Board on your set below:
