    Thanks for replying so quickly, some one else told me that it might be just a connection problem. I will check all the connection.

Hi there,

It's possible the logic board got damaged, but most of the time this is only a case of connector badly inserted. 

It usually happen after moving the TV (or if you just unpacked it). This usually require to open the TV and push on all the "things" that seem to connect to the LCD screen, follow any screen data cable or ribbon and ensure they are also well connected to the board. 

The white on an LCD come from the relaxed state of the liquid crystals. In that state all the light is permitted to pass trough. 

Because this is a end data path, no diagnostic monitoring detect this problem and power LED don't flash error code. 

In that condition the audio is usually OK, another thing that point to probably no failure of any chip. 

If you want to perform this yourself, be cautious, a TV have very high voltage inside it. You should also discharge any static you can have before performing such operation.

Good Luck!!
Thanks

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

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
