Visio tv L42hdtv10a - I accidently touched the input button... The tv had blue screen briefly showing "no signal" then turns off... I can't get it to stay on or reset... Please help...deb w/o tv
With out turning on the T.V., Push the [Input] button on the remote control. The TV should turn on and activate the input menu, just continue to push [Input] until it is set on TV (or HDMI, etc.). this should solve your problem.
After several hours of frustration, I finally read somewhere that you need to be sure everything is turned on....I think that I must have hit a botton that turned one of the hook ups off. Finally after three days....
You may try holding down the INPUT button during startup or pressing it a few times quickly.
If that doesn't help you may consider

TV is probably in the RGB mode. Since no computer is hooked up to the set it detects "No Signal" and will then shut off within seconds. To resolve you will need to attach a computer (laptop is easiest if you have one) to the TV RGB input. Turn on your TV and it should show what is on your computer screen. Then go to the input button on your TV and scroll to the input for the cable signal, or TV if no cable being used, and all should be good.
