Question about Sanyo DP42746 42 in. Plasma Television
I was wathing tv and the tv shout donw for no reason, no more image but the green light stay on but no image. I unplug the tv for about 15 min. and i plug back and the tv got on for about 3 sec. and tourn off after with no more image.
Ok Fellas I found the Problem!
The Problem is the V4 Y-Main Board.
This board is located on the left side of the case looking upright from
the back. I spoke with may suppliers, and Sanyo all confirming this.
Apparently it has been an issue for some time. Sanyo has replaced the
V4 Y Main board with a W1 Y main board in newer models. The W1 Board is
NOT compatible for us tho. Just to be sure... If your T.V is taken
apart (like mine) Disconnect the peripheral cable from the V4 Y Main,
and turn on the set. I bet it will power up with audio and channel
function just NO picture. When you plug the board back in... POOF set
shuts down. Replacement boards are VERY hard to come by. So Happy
Hunting!

Oh yeah.. just FYI, Sanyo, Phillips, and Samsung all use the same parts. Hopefully that will help your searching.

I think the power supply or logic board have failed, both are made by Samsung. My issue is knowing where to purchase replacements.

I had the same problem and Sanyo does not make parts for this model anymore. Luckily I had the extended warrantee so they reimbursed the full purchase price.
