You will want to check what is the model of your Sanyo, then contact Coppell TV Repair and ask if we fix the main board for this model - chances are good we do.

Prices are between $65 and $85 total as of September 2012 and you start by going to www.coppelltvrepair.com and following the "Shipping instructions" link.

But before any of that check with us if we service your particular TV model because Sanyo has lots of them and we don't do all just yet.

Try changing the input device to something you are sure, works such as a DVD player. Look for any jammed buttons on remote or on control panel.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

I have a 1 year old sanyo 42" lcd tv, model DP42849, The tv was running perfect till one day watching a movie, the screen went black and audio went all strange, i shut it off and on, and nothing, the power...


You need to find out if the power supply is putting out 24vdc for the backlight inverter board, it can be that the inverter board has short circuits which will cause the 24vdc to go into shutdown to protect itself, you can disconnect the power cables to the inverter board to see if you will get the 24vdc back.

Sanyo Vizon 42" Plasma DP42746 Was using tv when I heard a click and I lost all audio and video, could not change the channel or adjust volume. Tried unplugging and sitting for 10 minutes. Plugged back...


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.

No video but audio is fine on Sanyo 42" DP42746 TV


If you unplugged the Ysus board, then you need to replace the Ysus board, or both sustain boards. This is the part: The part is often available on Ebay, or from manufacturer. Look also at Vance baldwin or Partstore. To do a good job the Sustain boards should be tested by a tech , following service manual. It is almost for sure sustain board by the way.
