SOURCE: Thin vertical line running down the right side of the screen

See if you can use the remote to shift the picture to the right. It depend on how far the line is to the right. If that don't fix the problem the set will need to have internal boards replaced. It may be the logic board and the logic buffers...

One of your system boards is failing. Possibly the "Y" convergeance board. The LCD Capacitors will most likely have to be replaced.

SOURCE: Vertical colored lines on left half of screen.

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.

This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.

I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.

Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.
