My 3 year old shot water at the screen of my LCD tv. Showed the picture for awhile, then went white, now there are multicolored vertical lines. Will it dry out? How can I repair it?

Unplug it,then wait 10 minutes,then plug it back in.

If a LCD TV has vertical or horizontal lines, in most of the case the problem is a defective LCD panel.

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.

The tv could have a dead tv LCD screen panel because of it is damages by a person or an object by hitting it.Than the tv it is not worth it or repairable if it is require a new tv LCD screen panel.Will cost the same as a new tv,if tv require a new tv LCD screen panel replacement.The LCD screen panel tv that have multicolored lines run vertically on the LCD screen panel and people given it to u and said not thing.The tv probally have a dead tv LCD screen panel already,Sorry tv like this,it is a garbage tv now,it only can be used as a salvages tv only for it electronic circuitries boards only.

Unfortunately TV's aren't built to last anymore...once LED sets came out the life of them dropped in half over what they were 10 yrs ago.. 2.5 yrs isn't that far below average anymore. .There is a good chance you have Tcon board issues, you can try the old trick of cooking it in your oven and see if that helps since it started out as intermittent or would work for awhile and got worse but only about 20% at best of the time that works, you can find instructions on how to do it on youtube if you want to try, it won't hurt anything but chances are it won't fix it...next step is buy a tcon board but there are other things that could cause it , tcon would be where I would start

STK392-560 STKS convergence CHIPs Replace both of them.

it's called retrace lines ,your screens are set to high or focus block assy which has the screen adjustments on it also is faulty
