Question about Sanyo DP42746 42 in. Plasma Television
This is a common problem with these TVs. 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 the same issue with my TV last year.
The solution is almost always to replace the Power
Board (Y-Main) 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.

It sounds like your Y Sustain panel has gone out. Locating the part and the price might put you at the 50% category in which a new set at that point would be in order..
