I have had this problem since about superbowl time. If I powered the set off, waited 15-20 seconds, and then powered on, it would work again for a while. Repeating this drill a number of times would lead to stable operation. We resorted to a course of turning on some XM music from DirecTV when we weren't watching. I tried a technician knowledgeable on this set, and it would have cost $500-800 to repair the set. We learned from different forums that the likely culprit was either the power supply board or the LCD controller. We also picked up the rumor that Westinghouse had quit making replacement part. It would seem that the management of this organization has a death wish. TO THE CHASE: shopjimmy.com is now selling parts from canibalized sets. They have a non-DOA warranty and a good return policy. A power supply from "Jimmy" solved my problem. I have one important hint: To remove the back, take out the obvious screws and the base. Then remove the ~5/8" rods that protrude from the bottom. There is a screw up inside each rod.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Check for cold solder joints in the power supply board around the 24vdc section.

The problem can also be in the backlight inverter board also, but you need to find out if the power supply is putting out the 24vdc first.
