Question about Sanyo DP42746 42 in. Plasma Television
My sanyo plasma model number dp4276 has no pic or sound. We tripped the curcit breaker when my son plugged something in. I should have uplugged the tv and tripped it back but we just tripped it back the tv was fine after a couple of mins the tv picture and the power light stayed on. I turned it off and on and nothing but i noticed that the green light i see in the back is not on. I wish i would i have purchases that $100.00 surge protecter. Please help called Sanyo there are no help at all tv is out of warranty. So he told me to take it to repair shop.

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.

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

If you were to log on to the
manufacturer's web site, I think you will be pleasantly surprised as
usually one is able to download, by model number, Customer
Instruction Manuals, list
of Dealers for spare part supplies as required.
The information is normally free of
I hope this helps.
