Westinghouse LD 4080 when turned turn on the left side (50%) has vertical color lines and the rt side is totally fine. Suggestions?

Sorry, you have a defective LCD panel. If your TV is still under warranty, contact Sharp to get the TV exchanged. Otherwise, LCD panels cost more than the TV is worth.

This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

if the tv is less than a year old , call 1-800-SAMSUNG for warranty repair, the lcd panel is bad

One of two things could be wrong.. One is the digital board and or connector. the second is that the LCD display is going bad..

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.
