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!

42' HD V4 Y-MAIN
PCB: LJ41-02760A LJ41-02761A LG92-01200A BN96-03352A

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

After hunting for 2-3 months for the Y-Buffer Upper assembly, I finally found a parts dealer...

http://www.partstore.com/

Phone Number: 1-866-925-7278

PCB: LJ41-02760A - $84.36

And yes... Dell, Sanyo, Phillips, and Samsung all use the same parts.

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.
