Question about Vizio L32 32 in. LCD HDTV
Usually if the LVDS cable between the main board and the T-CON board is bad, you will loose one of the three color signals, you may have thermal problem with the T-CON board. I would run the TV with the back open to see if it will take longer for the problem to appear, or get a can of freeze spray for electronic troubleshooting and cool down the T-CON board (board is under the metal shield that you will have to remove to get to all the cables, I would remove the shield and put the screws back in to keep the T-CON board in place).
The TV as shown in my album has bad T-CON board, the pictures get pixelated and scrambled after about 1/2 hour, I was using a small fan to keep it cool until I finally found a replacement T-CON board. Bad LVDS driver IC on the main board can also be the problem. Right now we need to find out if it is heat related problem or not.
