My toshiba lcd tv has a black screen i have no picture or sound


Hello,

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.if otherwise TURN THE TV OFF AT THE MAINS. This will reset it to default. Wait 1 minute at least.

- TURN TV ON. Ensure you have sound so you know the video/audio feed is OK.

- PRESS THE TIMER BUTTON ON THE REMOTE
you should now have picture or at least response from the screen indicating what channel it is on.


I hope this will help to solve the problem..

Toshiba 22LV505 TV-DVD:


Check the DC filter caps in the power supply first. Check the 24vdc (or 18vdc for this 22" model) to see if it goes away when the screen goes black.
There are main AC fuse, backlight inverter fuses, T-CON fuses.

Screen went blank sound ok


Do yo have the remote? Do you have the manual? Manuals are usually available online.
If you are feeding the Toshiba with cable wiring then the problem is with the Toshiba. Maybe something as simple as the wrong input is selected on the remote control. If you are feeding the Toshiba with audio and video cables then the input to the Toshiba would be suspect. Either cabling (the inputs and outputs are plugged in wrong. If you changed anything I would retrace your steps.

Let me know by clicking on 'ask me' and if solved please do the rating. Thanks.

No picture


Depending on the make and model of the TV, the problem can be a poor connection such as a dry-joint on the main board or a failed line-output stage or simply a physically damaged screen. The latter problem can crop up when the TV is dropped, for example. Please feel free to specify make/model and what happened prior to the problem.
