Dark band 6 inches wide middle of the screen

Usually either the main board or the power board--if set is 6 months old---no warranty?

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (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 updates will be on my Facebook page.

Important Warranty Announcement for LCD TV Owners

go to the menu and try the plasma restoration first you should leave it untill is done, usually it takes a couple of hours, now if that doesn't solve you problem you have a bad screen dell plasma are famous for this,

ps: do not perform the plasma restoration frequently that should be done only once every 6 months you could damage the screen.


good luck

Philips 50 inch plasma tv no video but has sound

I would suggest to exchange if you've noticed those lines. Do not wait for too long.
Good Luck

Sadly, the plasma screen is failing. The green strip is no longer functioning properly and the failures will continue to progress.

If still under warranty, get it exchanged.

the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger,
the small mirror is in front of the lamp and bends the light,
remove the lamp and look down the tube (light path)
