The screen has colored vertical lines and becomes to a dark black band about 6 inches of width.The tv is exactly two years old by today.


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.

Turn off CC1,2,3 or 4. You are seeing a Closed caption screen with either no data or encoded data. Usually the blank CC's are 2,3, or 4.

Black square covers the center of the screen-


the closed caption is probably on. look on your remote or in the tv menu for cctv and change the setting. there are at least four different types of cctv and you may have to cycle around some to find "off.

Black screen


I have a Sharp Tv that had the same problem with a large brownish or black square right in the middle of the screen. It only left about an inch around the edges that you
could see the picture moving in behind the big black block or square.I have DISH sat-elite and the book recomending that I check and see if the "caption settings" were on
or off. They were on. I turned the caption settings off and the large square diappeared.

Black square covering up most of the screen


Try goeing into your Menu and see if you have the closed Caption on that will produce a black box on the screen if you have the owners manual look in there,if you don't have it you can go on line and download it from the manufactures website under Downloads Good luck Walter Grzybowski
