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.

No, I'm sorry, but the technology to fix the actual lcd SCREEN is not out there yet. The reason you don't see it when it is off is because it is actually the inside of the screen that break, unlike plasma tv's, when they break there will be actual glass fragments. If the broken area is to big to deal with, then the options are; buying and installing a new screen (alway about the same price off the tv new, or more), you could sell the insides of the tv on Ebay for example, they are very much needed parts (powerboard etc)....Those are about the only options, unfortunatly...If selling the powerboard, you shopuld be able to get around$100 for it...

Once again, I'm sorry I didn't have good news, but please rate if it was usefull, thank you!

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.
