Recently our Vizio TV started to act wierd. Sound, chanel changing and power is all normal. When the unit is turned on the screen images are normal, but the color of everything is like looking at a photo negative. After leafing the unit on for 5 minutes the problem went away. Then ten minutes, then 20, 30 and now no matter how long you leave it on, it never corrects itself. I'm pretty handy with small electronics. Im just trying to narrow down my first move. I can get a replacement video controller card for about $65, but from reading a lot of the postings here it seems like the main board is a likely culprit. They are about $120. Any suggestions would be appreciated.

Re: Vizio 42" LCD with Screen problem
Find the LCD Controller board (TCON). Disconnect the cables from it to the LCD panel. Carefully re-connect them. Make sure the cable is properly positioned in the connector. You may have to do this several times to get it work. The flat cables are a problem.

Remove the batteries from the remote then see if the set returns to normal and you can use the buttons on the tv. If after the batteries are out and the set is still acting upreturns back to normal then the remote is bad, I have seen cases where something has been spilled on the remote and no one was told.
I had a similar 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. I didnt hear an arcing sound though.
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. I would check the ceramic fuse first on the board that gets power from the plug.
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.
Just try to reset so picture will back to normal again, some LCD TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time. 1. Unplug the LCD TV power cord from the power outlet. 2. Unplug any connected devices (DVD, Set-top boxes, etc...) 3. Press and hold the LCD TV power button for five seconds. 4. Plug the LCD TV power cord back into the power outlet and turn on the TV. 5. Open the on-screen menu to confirm that the LCD TV is responding again. 6. Turn off the LCD TV and reconnect the devices. 7. Turn on the LCD TV.
thats called PIP aka picture in picture on your remote theres a way to turn it off or change the chanel of it what it is its like another tv but with no sound and you see another chanel or video input on it and you can switch it on the remote
May be a bad power supply, which is a common problem with these units.I have a GV42L 42" manufactured in march 2007. It works perfect except the screen has a fracture on it. The warranty is voided because we damaged the screen. I can sell this to somone who has a good screen but needs boards or speakers, etc. Or I will buy your tv that has a good screen but damaged boards in it. firstname.lastname@example.org
If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on. If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
