Plasma TVs are difficult to repair. I have not repaired the particular model you ask about. I would certainly pull the power supply board and inspect it for a bad solder ground. Many times this will repair the TV. Be sure to also take a leaf blower to the open back of the TV as well. Dust will act as an insulator, and create extra heat that will break your solder grounds. If worst is to meet worse, you may have a bad Y suspension board. The Y suspension board will take some effort to remove, and if this board is bad, send it in for repair. But let me remind you, the first note of this info is the best effort to fix at any level, and is usually the problem. Also, there may be one bad capacitor on the power supply as well, replace with same value. If you cannot repair this TV yourself, take this info to a TV Tech.Thanks for asking me!

It's either the backlight lamp or backlight inverter is busted
due to a power failure or fluctuation. Here's how to determine which is which:

Ur backlight video inverter board is dead.Buy parts like capacitors for replacement with soldering or buy the whole board.Tries these websites.Shopjimmy.com,Partstore.com or Ebay.com.

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.
