The Sanyo 50 inch plasma keeps freezing with the image of what ever we are watching on tv. It happens every three minutes or so. Also, the image from the tv will sometimes stay on the screen even after shutting off cable and shutting the tv off. We have only had this tv for less than one week!!! Help

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.

SOURCE: 50 inch Sanyo Vizon Plasma TV. Has sound but no

This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.

Quite common.

Repair estimates should be $250 - £350 depending on which has failed.

Stick it on eBay, it will fetch good money faulty.

Testimonial: "Thank you for your response. We were driving ourselves nuts - fuzes checked out fine and not other guess where to turn. We appreciate your help!"

SOURCE: sanyo 50 inch plamsa just quit!

Woke up this morning and my 50 in won't turn on. 2 years pld next month:( How to fix?

SOURCE: tv not responding to remote

This may sound silly but does the remote have a funtion button or buttons at the top of the remote? It may be set to operate a DVD or VCR instead of the TV.

Failing that check the batteries, it is very rate that your TV will stop accepting IR signals.

Hope this helps,

Cheers

For what it's worth, you can download the official Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html. I uploaded it here when I had some issues with this TV last year. The solution almost always seems to be to replace the Power Board and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but a repair shop):
1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.
