White screen only on Sanyo DP26648

Have had TV for 118 days, has always worked perfectly.

Today, I turned it on and it will only display a white screen. I've unplugged the power cord, cable, and all inputs and it still displays the white screen only.

    Exact same here. Have had tv for approx 180 days. Turned on yesterday and only white screen. But could still hear audio. I manage to get a picture ONCE since it happend by repeatedly pushing channel up/down and reset and powering tv on/off. Have not been able to get a picture since.

    Would love there to be a solution but I'm afraid the answer is going to be costly repair.

Your reported symptoms are odd in that most failures are related to the primary power supply but that takes down both audio and video.
The backlight is obviously working (white screen) but it is no longer receiving any video information and this points to a failure of the logic (or the output of the power supply that services logic) used to control pixels on the screen.  Some screens have the majority of the control ICs actually mounted on the LCD assembly and because of very close pin distances used on dense ICs, they are often not replaceable by hand since they were installed by robotics.
I would first suspect (and hope for) the logic voltage output of the power supply to be the culprit. 
If any of you posters have had a repair done and received any kind of a detailed report (you should), would you be kind enough to post it back as a comment to this original message?

Mainboard is out.

But, make sure output voltages are there. You will have to test it in 5 second intervals and after 3 tests remove power from unit (logic chip prevents more than 3 attempts without power reset) for 10 seconds and try obtaining voltages again 3 more times. Usually takes 5-7 on off cycles to get all the voltages.

On the link below, the answer was given to one person about a different type of TV. My TV has been doing the same thing but these two incidences might be close to the same problem. I have yet to find someone who can repair the TV though, but if I do and that person says that was the problem I will make another comment letting you know. Course I may be wrong one saying that these two incidences on two different TVs are haveing the same problem, but I thought I would share this information to others as a just in case

Hi there I got a Sanyo 26" lcd hdtv replaced the main board and tested voltages as the service manual indicated and all of them are fine, could you tell me where is the T-CONN board in this...


The t-con board is always at the top/middle if all lcd's. If it doesn't have one visible then it is built in the display and therefore non serviceable. If it is visible and after replacing it does not cure your problem then the display panel is bad then the set is scrap. The display will cost as much if not more than a new set.

Neither "solution" is a solution. Anyone actually


Hi,
Your problem is the T-con board. This is gone bad/faulty. I would advice you to replace it with new T-con board and your unit will back to normal again. You may look for the replacement online. Try ebay.com or shopjimmy.com.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

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.
