I have a 2+ year old Toshiba 32" TV which has operated flawlessly--until our recent move. Now after being turned on for a few minutes, a vertical line 1.5 inches over from the left side of the screen appears. This line runs the entire height of the screen and is about .25 inches wide. It "pulsates" and distorts the picture "behind" it, but it is essentially fixed in location. This band does shift color as the signal changes color. In addition, at times additional (aalthough much less distinct) vertical lines will rapidly "roll" in sync together What is this problem likely caused by? How much should I expect the parts and labor to be for a repair? Could rough handling cause this problem? Thanks for your help!
