This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.
Repair estimates should be $250 - £350 depending on which has failed.
Stick it on eBay, it will fetch good money faulty.

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.

I just bought a Sanyo DP50747 50 inch plasma. When I pause the tv, then push play (even 1 minute or less) the sound does not start as soon as the picture starts back. I have picture first and no sound for 4 or 5 seconds then the sound continues from that point.
