SOURCE: no picture

The way to isolate the failure to the power supply would be to measure the voltages going to the backlight inverter board. If all the voltages are normal then is more likely a defective backlight inverter board or LCD controller board.

Oh yeah, you can most certainly change the power supply by yourself.

It's easy to locate - just follow the power cable - and easy to replace.

Only make sure to let it discharge before you operate it. 10-15 minutes disconnected from power should do.

However, there's no guarantee that the problem is in the power board.

There is a very good chance it is, in fact, not there.

There's another board which commonly fails on many plasma TVs and the effect is exactly as you describe. It's called Y-Sustain board and you can tell which one it is by looking at the side of your TV and seeing which large board has manny plastic connections that enter the display on the side.

That board often has one or two fuses on it - I'd check those first.
