I've had the tv for less than a year, and just today when I turned it on, the colorful lines appeared across the entire screen. Last night it was working fine, and now all I hear is the fan running inside. Attached is a picture of what it looks like. When I turn it on, the black screen is on for a while, and then turns to this. Nothing seems to work, menu, volume, channel, etc.
I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.
Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.
Unfortunately, what you're describing is a repair
issue. You won't be able to address the problem with troubleshooting.
There is a part inside the TV that needs to be replaced. If you're
under warranty, this will cost you nothing. If you're not under
warranty the cost will likely be a minimum of $200 parts and labor.
However, be warned that the cost could be considerably higher.
