Sanyo plasma switching off!

[nstlfrk]

Hello all I have a Sanyo Plasma that when you turn it on it starts to light up but then shuts off. I cant find any blown fuses or shorted parts and all the caps appear to be good. It just clicks when it turn on then of course clicks when it shuts down. Sometimes it will do this multiple times and other just once or twice. Can any of you give me an idea of just what it may be or where to start?
Thanks

When you say "light up", do you mean the screen glows briefly? (if only dimly)

exactly what I mean. Does not show any information as input or video just a light glow.

OK, look at these two boards

Is an LED glowing on them? If so does it stay lit? Do both glow?

There is a green led on the one on the left for sure. It just stays lit solid.
I will have to check on the right one.

On some Panasonic panel modules, there is no LED on the SS board (right hand board)

Your TV has Sanyo main A/V board and software, but the display panel and driver electronics are manufactured by Panasonic (a good supplier.)

This is a very common problem with this model. It is a defective main board. There are repair kits on eBay for the main board but at times it's a hit and miss with it. Just wish someone would help figure out what was in those kits.

Do you still need me to check on the other board for the led?
Also why does it matter if the LED is solid, on or off?

The main board as in the one with all the inputs on it?

There is no led on the right board only the left and it stays on solid.
What do you think this means?
