Viore PD42VH80 42" Plasma, NO Picture, YES Sound

[z0nghits]

Hey all,

I have a Viore 42" Plasma TV (PD42VH80) that has just recently lost picture. I still have sound and have tested all cables/connections. I get no video at all, no TV menu, channel numbers etc. I tried to do some research and found a previous thread from a similar TV: http://www.justanswer.com/tv-repair/...t-walmart.html

Although my TV is slightly different, I followed the same process and unplugged all cables from the power board except for the 120VAC lines in, and the white connectors at the bottom. The board to the left (y-sus) is disconnected, but it appears it shares a connector with the z-sus board too, so that is also disconnected.

Using the VA and VS test pins on the power board, when I press Power, VA goes to 53VDC and VS goes to 207VDC. However, they only sit at those voltages for a few seconds then start draining and eventually go down to 0VDC. There are 2 fuses on the power board, both check out OK.

Here are some pics..

So with the y-sus/z-sus boards disconnected, the VS/VA voltages should hold right? Is there anything else I can check on the power board to troubleshoot it?


Thanks in advance!

Any ideas?

I have no problem ordering/replacing boards just if I could narrow it down to y/z-sus or power board it would be really helpful.

Thanks
