Turned my sanyo dp42410 off last nignt and now it wont turn on no led light on he front nothing

The CS-9028iT remote control isn't one that I can find a reference for. The CS-902831T was a standard accessory with several Sanyo televisions models. One of which was the Sanyo DP42410. The manual for this TV is available here: https://www.manualslib.com/manual/261846/Sanyo-Dp42410.html . The page on using the remote control is available here: https://www.manualslib.com/manual/261846/Sanyo-Dp42410.html?page=9#manual .

I hope this helps.

The main board has some issues and would need to be replaced to fix the issue

Get the codes read, this will point you in the right direction!

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/

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!

Power supply board have problems,not giving the tv,the right voltage anymore,that why the LED power light indication go off.The power supply board,that the board,where the power a/c plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

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.
