No picture


A very dim picture in this case may be damage to the power supply of the set---If a LCD set it may use back lights of some type--if not on or at full brightness the picture will be very dark.

If I was looking at this set I would open and check to see if voltage for the back lights is correct first.

Colour on the tv is too green and red model 26av502U. Less then three years old. Reset to factory default settings per manual instructions and it didn't work


If you are using component cables change them out. It sounds like they're faulty. Try another device like a dvd player on a different input with different cables to see if the picture is still too red or too green. If so then the tv needs servicing. If not you can rule out the television.

We just purcased Toshiba 26AV502U, now the screen is blank


Heard back from Toshiba. They said to unplug the TV, wait at least 3 minutes, and then plug it back in. This should allow it to reset itself. Sounded too simple, but after doing just that the tv has worked fine for the last three days! Toshiba noted that if this didn't resolve the problem we should contact them to have a Toshiba Authorized service person come check out the tv. It worked for us, hopefully it'll work for you too. Good Luck

Toshiba 26AV502U (new) video dropout if VHS tapeis not perfect


Had problem checked by local outfit called "Circuit Pro"; their analysis was compatibility.
Actual answer was that the Toshiba required a better quality input from "any" VHS source.
I finally took a "less than perfect" VHS tape with me when I returned the Toshiba TV to the store and demonstrated the problem to one of the TV sales people. He played the VHS tape through a display VHS/DVD player to three different brands of TV. The picture was often "black screen" on a Toshiba, but was merely poor quality on the other two brands. I upgraded to a Sony KDL26M4000 from the Toshiba 26AV502U.
