    its an lcd...LVDS eh...suggestions on where to purchase. Was just thinking of purchasing a main board after reading a post on a GV42LF as the symptons were similar.

  • crewzen May 18, 2009

    unless an LVDS is a main board??

  • Anonymous May 18, 2009

    Now I am hearing that I most likely have 2 LCD controllers. This true? do I need to replace both? If the whole screen is backlit with no images ever, not even menu/input/volume info...why would this be 2 LCD controllers? Starting to go back to my original thought of main board.

    Wifes about to kill me. Someone help please!!

If this is indeed an LCD and not a plasma, then you need to replace the LVDS (LCD controller) board.

    Main board is different than the LVDS. The LVDS (LCD controller) is usually mounted right on the back of the LCD panel. Main board and power supply boards are usually quite larger and have to come off in order to get to the LVDS. You'll see a brown ribbon going off this board right into the LCD panel itself. :)

Had the same thing happen to my Vizio TV. It was on warranty, and they replaced the motherboard. It's been fine since then. There appear to be only a very few parts inside. Power supply, motherboard, and display. That's it. Your power supply is good, as is your display. You just need a motherboard.

The LCD screen is dark with no sound or picture when turned on.


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:Look through the back vents for a white light to make sure the backlight still works. 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.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.
