Unplug it for about an hour to let it reset itself, if it is still does not work, then you need to do some troubleshooting.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there are some troubleshoot you will have to do to find out the causes of the problem you are having.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

SOURCE: What could cause a 27" Sanyo flat panel dp26648 to lose picture, but keep sound?

There are two reasons why your Sanyo DP26648 would has sound but no image and both are equally likely in our experience.

First, you may have a problem in the section of the power board that supplies the backlight module (called inverter) with 24V.

We've seen that several times and the problem is usually minimal - only electrolytic capacitors gone bad - and other times not so minimal.

We have a repair service for that power board and we may have some boards available too...check out at

2008 sanyo lcd tv DP26648 power turns on but no picture or sound


likely a mainboard or power supply capacitor issue.
if you have the soldering skills fix it, otherwise time to replace the TV.
If you can de-solder and solder in new capacitors make sure you are using high quality capacitors be very causious of capacitors purchased from auction sites.

Sanyo DP26648 cable problems


I have a sanyo dp26648, just had it over 90 days and it quit. I can hear the sound, but no picture at all. Just a bright white screen. I can't even go to the menu. I bought the extended warranty but there in not anyone in my area to fix it. They told me I would have to wait until they found one close.
