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.

No, I do not have a solution, but go ahead and post this as a solution since there are no other options for replying to a post, or commenting to say you have the same issue as "solution #1" has done.

Scratch on sanyo flat screen tv


The overlay or outer screen on any LCD or Plasma is bonded to and cannot be removed/replaced short of replacing the entire Panel or display unit which needless to say costs more than the set did when new.

If its an older projection set the outer clear screen may be available depending on brand and model number.
