Please recheck your contacts at the back or front of your TV. Power off your TV, then pull the cables fully out the jack and back in.

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.

Tv have a problems known as a convergence problems,it dead.The tv have colors lines R,G,B mis alignments,have a colors shadows or 3D pictures look alike?Ur tv convergence board have dead 2 STK convergence ICS and some or all it resistors too.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

Best advise! Sell it or exchange it for a better TV. Your old TV
may not more than Rs. 800/=

Now a days you do not get talented technicians and original
spares. Do not attach sentiments to the TV. If so keep it in one corner
and go for another TV.

tv problems are due to problems with the horizontal frequency and the horizontal width, spare part must be replaced is electrolit condensator (elco) in horizontal area. you can find written elco size: 1uf/160volt, or 4.7 / 1 160 Volt.and uf/50 Volt. it will cost about $ 10 - $ 20

try degaussing the picture tube

my mitsubishi 73" set is 4+ years old. all of a sudden the color is all wrong. after a couple of minutes of clear picture the colors change--blue is green and red is yellow. a little while later everything has a red tint to it and there is a line going down the center of the screen. to the left the picture is still relatively sharp, but the right hand side is terrible. I'm hoping this is just the lamp.
