Plasma screen is blue it has been taken off wall think something may have been touched/flicked


Blue screen means no input. First make sure the HMDI cable and the device you get your golf results from is properly sending the signal. After that, you can then make sure that the TV screen itself works right by using the remote to change volume and ensure that it the screen shows the volume up graphic display. Once you know that is in working order, make sure you are on the right input channel by looking at where you input is plugged in to and setting the TV to that input via the remote. You can repeatedly hit the input button to cycle through the inputs if you want to be sure. (there are 8 of them) The last thing you can try is assume that the input you are using is bad and switch to another. (Go from HMDI 1 to HMDI 3)

No picture only a blue screen


A blue screen usually means no signal is recieved or supplied - try changing channels to ch. 3 or hooking up a dvd player, if available, to video inputs and select that input on the TV.

Somehow, the Input got switched to RGB,and now I can't get by the blue screen before TV (VIZIO) shuts itself off after posting a "NO SIGNAL". Is there any way to get past that blue screen so I can change...


the brand and model of the tv would have been helpful, but try connecting something to the rgb so it stays on, then use the remote to change the input on the menu or settings.

Tv screen has turned blue and I can't watch tv


i think by accident you have changed the input when you went to change the volume. look for a button labeled " input" or "video" select on the remote and scroll through the various choices. you should get your picture back.

Blue screen, no video, but has sound


Did you hit the "input" or "video source" button by mistake on the remote or TV? That would change the input from the one the cable/video source uses. You're getting sound, so it's working......sounds as if the input was maybe changed. I'd hit the input/video source button a few times to go through all the available inputs and see if you get video back.
