SOURCE: 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

SOURCE: TV set self turn off after few seconds

It sounds like the voltage regulator in your power circuit. Also you have a capacitor that's going bad somewhere and won't hold a charge. That's why the picture is fine for a while then turns green. Unless you service TV's this one will have to be brought into the shop. Unfortunately it'll cost more than the TV is worth to get it fixed unless it's still under warranty. These days TV's that small aren't worth fixing. You're better off buying a new TV.

LE46M86BD SAMSUNG LCD Picture issues (turning off after 5 secs)


you will need a tech to isolate the fault. could be power supply board or the main board but I suspect it is the lcd panel itself that is failing.

White line accross screen holds when picture goes up and down.


This can be caused by the contrast being set too high. Typically, for a Sky box the TV's contrast should be set to around 65.

If this does not help, then the LCD panel is probably at fault.

Blank screen, no sound


If ti blinks three times, then it may be an issue with the flyback transformer. It's called "three strikes"...it tries three times to come on, and after that enters a safety shutdown mode to protect the TV. Might need to have a professional shop take a look at it.
