Question about Vizio VW42LF 42 in. LCD HDTV
The Visio logo on under the screen will light up when the TV is turned on. The remote and the button on the unit work for this. The screen is black and there is no sound. Tried a different TV wtih cable box and it works, so I know it it not a problem with the feed. To turn off the tv, you have to unplug it. It will not respond to the remote or the button on the unit.
I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.
HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine.I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

I don't know have you done an all factory preset to this set, after replacing the main board. If you have already done it, and still you do not get a stady picture, firmware update may necessary. If you haven't done a factory reset till now do it.
From Menu, press 'Down" button to highlight "Reset All" setting selection.
Press "Right" button to reset the TV to its original factory settings. Once the adjustments are completed press the 'LAST" button repeatedly to exict the OSD completly. This does not reset the Parential Pasword set if any.
