HD TV flat screen

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.

Check its T'Con board. This is a common fault to all type of LCD TVs

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.

Connect the cable to your TV's antenna input jack. Through the TV setup menu, perform a digital cable search. This is a separate operation from the full channel scan. The TV manual says this may take up to 10 minutes, so be patient. The set should find the channels on your system. When you want to watch TV, press the INPUT button on your remote to select Digital RF as the source. Press INPUT again to select any other source (DVD, etc.) you have connected when you want to watch that.

I was wrong about needing a converter. This TV has a tuner that can pick up the cable channels if they use a system called QAM. Verizon says QAM-capable sets don't need a box for non-scrambled or premium channel, so you should be good once you have the TV scan channels.

I couldn't find the DP26648 manual at Sanyo's site, so my solution is based on the DP26647 manual. They should be similar. You can download the manual here if you don't have the manual for your set.

I called sanyo ,they had me try this and that and then said a tech guy would call back he did i am taking the tv to a repair shop and it will be fixd under the warranty.

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.
