Toshiba TV problems no picture no sound
This problem, for an instance, can be caused by a variety of factors. Before you spend money on fixing or replacing your television, try diagnosing the issue. You might be able to restore the picture and sound on your television and save a lot of time and money.
Step 1
By hitting the power button on the TV’s remote or the front panel of the set, make sure the TV is turned on. This may seem obvious, but many TVs have a standby light that illuminates when the TV is turned off, giving the impression that the TV is on when it is not.
Step 2
Verify that your TV’s video inputs are set to the correct one by cycling through them. If you try to utilize a digital cable converter box with a Video 1 input and the TV is set to a Video 2 input with nothing inserted into it, the TV will not display any picture or sound and may even display “No signal” on the screen.
Use the input selection button, which is usually labeled “input,” “source,” “TV/video,” or something similar, to cycle among the inputs.
Step 3
Re-seat the video and audio input connectors to make sure a loose cable isn’t the blame for the TV’s signal loss. If you have a coaxial cable running directly from your wall cable jack to your television, it may have come loose, obliterating all sight and sound.
Find the connecting cable or cords for whichever device you’re trying to watch and disconnect them from the TV’s input. Reconnect them and look for a signal. If the picture or sound is still not working, the best choice is to contact Toshiba technical support for assistance.
