SOURCE: Toshiba lcd 42x3030db sound but no picture. just went black screen??what do i need to fix if possible.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, it can't be replaced. In this case; a panel replacement is the only repair.

Suddenly no sound is coming from the tv


Unplug set and or a box if used for a while and plug back to let units reboot.

Look in menu to see if speakers are switched on or off.

Look to see if a DVD etc connected to a rear input has sound or not.

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

DVD playback no playback


Sounds like the scart lead is not in straight. Scart connectors have the audio pins at one end, and the video pins at the other. If the lead isn't in straight then you often get sound and no picture and vice versa.

Check the connection by pushing the scart lead in securely. (Both DVD and TV end of the lead)

Failing that could be a dodgy lead.
