SOURCE: turned my sanyo dp42410 off

Good day!

The problem of your TV is on the power supply.
Please follow this procedure for D.I.Y troubleshooting.

  1. Remove all screws at the back.Open the cover.
  2. Power ON the TV.Check the input voltage of power supply from the cord.If supply form the power cord replace it.
  3. If you have voltage supply from the cord.Check output voltage form the power supply board and for sure you have no supply on it because the indicator didn't lights up.
  4. Check your power supply board such as fuse if busted,power transistor and diodes if shorted,open/change value resistor and leak/bulge on top capacitor.
  5. If you found that replace it and try to power it on again.Then check the output voltage such as 5vdc for the system board,12vdc for the sounds and 24vdc for the inverter.
  6. If you got that 3 supplies your TV is OK.
Note:If this procedure is not fix your problem it means the power supply got a major trouble and not for D.I.Y..I suggest to you as a technician to buy a new power supply board or give to the qualified technician.

I hope this solution will be helpful.Thank you very much and good luck.

Dp42410 sanyo flat screen tv is not powering on


Unplug your TV and run a jumper wire between prongs. Use the ohms setting on a multimeter to verify continuity. If the cord is good it's probably your power supply.

How do I get to the service menu ? Sanyo Model DP42410


Press the volume + and channel - buttons at the same time for about 5 seconds. It must make it into service mode. But, what are you intended to do after entering this mode? There will be a special screen display, that will not resemble to normal user menu. Any data value set here should be changed very carefully. Improper data setting to this mode, might even make TV iresponsive to any external signals, means, the TV has gone for ever. If you do not know anything about this mode, and adjustments, never enter into it. Let it do by any experienced service technician. For more procedure to get into service mode and to make adjustments, check this link, if you wish.http://electronicshelponline.blogspot.com/

Sanyo TV Code for Dish remote 21.0 IR/UHF PRO only operates TV Power and Volume Functions.


Hello Witt Thomas,

I can understand the concern and wanting the remote to work the TV Menus. It is possible with our remotes, however it depends on the TV itself. I've seen instances where there are 2 TV's in one house, and 1 will do it, while the other won't.

If you have tried all of the remote codes, and none work, the only other options we have available are to try a powr scan, or teach the remote. This link http://www.mydish.com/support/teach-learning-remote-20-21 can provide the steps on how to teach that model of remote control!

Let me know if you have any other questions.

Sanyo DP42410. Everytime i turn the tv on/off it's like i'm plugging it in for the first time. I Have to set up Home or Store, etc. All the settings. We just got the tv. Set everything up, and when we turn...


I had to call Sanyo on this same problem, and I just wanted to help you out on this. When you turn on the the TV and it asks for home or store, chose home then do the channel scan. After the channel scan completes, switch to your tv source, hdmi1, then turn off the tv and back on and it should just go straight back to hdmi1. Let me Know if this works!

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.
