Question about Televison & Video
When I turn on my tv from a cold start I only get a picture on the right side of the screen. The left side has only multi colored vertical lines. After warm-up< (aproximately 30 Min.) I get a normal screen. After about an hour the left half goes out again.
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.

I had a similar issue. Took it in and apparently i had 4 bad capacitors and after replacing those, my tv was perfect. But I think I lucked out on this one. :) try it.
