Vizio 32" Plasma question

[joshthrope]

Hey guys,

Wondering if anyone might have any insight. I have a Vizio plasma tv that was given to me a couple of years ago and it has worked fine until one day I heard a click (Not the deadly pop). The TV went out and will not come back. On inspection I find that when I turn it on it starts to go through the startup procedure and I have 5v coming out of the power supply to the Ysus board. A few seconds later I here a second click from the power supply board and the voltage is dropped out. If I unplug the ysus board and turn on the TV, the voltage does not drop out.

I do not have any popped capacitors on either board and do not see any sign of damage to either board. Wondering if this sounds like a simple power supply problem or do I need to trash the thing. Seems to be either the Ysus board or display issue. Any help would be greatly appreciated.

Sounds like a short once something is switching in.
Is it the buffer board y or y sus main? If you can get hold of a new/second hand pcb and try it, thats the way id go.
Are you uk based?

We need a model number please. If you can unplug the y board and the power supply doesn`t shut down You need a y board and possibly buffer board replaced. We could help you more if we knew who made the pdp for vizio. It could be l/g, samsung, or panasonic. Pictures help too.

Goodluck!
