Came back from vacation, Vizio Model V0320E sound ok, but no picture, not even the blue "no signal" screen, when hooked up to DVD... Same thing, light in back (white) is on, but no picture...nada...zip.... Even when hooked to computer as monitor...no picture...help...please.

SOURCE: NO RGB SIGNAL - VIZIO HDTV TO LAPTOP

I've been online looking for a solution to this problem and couldn't find a fix until today. I just got off of the phone with a Vizio Tech. He told me that some pc's have a way for the monitor to show the screen externally, and that there's usually a button, sort of like the input option on your TV but its an output button for a laptop in my case. It should look like a picture of a TV in and out of each other. Mine was located on the number four key. I had plugged in my wires and put the TV input on RGB. then on my laptop pressed the function key and number 4 key at the same time and what do you know, I had a picture on my screen. I almost gave up on my vizio but love it even more now. I hope this helps.

SOURCE: can I purchase a replacement screen for my vizio

you can try this place that sells lcd parts shopjimmy but typically the lcd screens cost more than a new TV does.

Check the tuner i/o board connector there might be a loose connection from the soccket.

I/O board means input output board, this is where the antenna and audio video input are pack in.It is just inserted at the socket..check whethere the connectors are lock properly
