I have a Samsung PN50A450P1D 50" plasma TV. I've had it about 7 years with no problems. A couple of days ago about 5 columns of vertical RGB lines and a black vertical bar about 1.5" wide showed up on the screen about 12" from the right edge of the screen. From what I have read it might be a bad logic board, bad main board, loose connectors, or a bad screen. I'm willing to open it up and check connectors, replace a board, etc. if there is a decent chance that it will fix the problem. But I'd rather not go through the trouble if it's most likely a bad screen.
