SOURCE: my sanyo plasma flat screen tv will not come on....

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.

SOURCE: I have green or purple or dark lines scrolling up the screen on my Sanyo 42 inch plasma TV

These lines are often caused by interference. Try putting a filter on the input power plug. Make sure there is nothing near by that can be causing interference, like another monitor or computer, microwave oven, fluorescent light, etc. Make sure all the antenna leads are tight and the converter box well grounded. Is this dish or cable?

Change input device to some other like a DVD player and see. Check for loose contacts in power outlet, RC cable, jack and socket.

Television comes on and then screen goes very dark. We have been able to check the menu contrast, tint, brightness, etc, but nothing helps. What do we do now?


most likely a defective Z-SUSTAIN board failure if the video looks somewhat correct and the tv is just dark. the Z-SUSTAIN board basically powers the plasma panel and if it fails a certain way it will cause this problem with the dark video. if you can get the tv taken apart and look for part numbers off of the board on the far right looking from that back then you may be able to find the part on the internet somewhere otherwise Contact Sanyo Manufacturing Corp 1-800-877-5032. good luck
