I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

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.

Call Sony my friend. I have the same exact issue with the same model. They already have a recall for the 46"XBR4. Let Sony know that us 52" owners are having the same issue. I'm essentially calling them everyday until they fix it.
