your backlight burnt out, this will be a maybe several hundred dollar repair. the screen is backilt by a very expensive flourescent light, without that light, the screen will be black.

An lcd screen cannot be repaired, only replaced and for a cost around what the went for when new. You can try looking on ebay or craigslist for the same model and swap parts. Had it happen to me, it sucks. Also your home owners insurance should cover it. Sorry thats all the help I can be.

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.

There is no solution this has happened to me 3 times in 13 months each time they replaced the screen panel (basicly the whole TV) I have a 2 year service contract, the next time it does it they will not bring it back but will write me a check for the price I payed for this peice of ****.!!! Do not bother fixing it.
