This is common and very likely the LCD panel has lost its connection at those points around the panel. Most repair shops don't even try to fix it as it is a huge pain to try. You should be able to get a warranty replacement if it is new.

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.

Hi:
This is due to low voltage getting to the Inverter board or the Inverter board on the bad side is not lighting the lamps. Usually bad capacitors or the power supply and the inverter will cause this symptom. You may want to replace both inverters boards on this model, new models have one inverter board for both sides of the backlight.
