SOURCE: 40 inch lcd blue line vertical

The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

It may due to the Logic board, or Logic Scan board, or the Panel failure.

This most likely a problem with the T-CON board.

If this set is under warranty you should return it to get it repaired/replaced by the seller.
IF YOU KNOW HOW TO WORK WITH ELECTRONICS REPAIR(board replacement ) or have a friend with knowledge/skill you can fix it.

Sometimes due to heating/cooling or contamination the connection pins on the T-CON board and cables do not make good contacts. The T-CON board is located in the center of the set.


After taking off the back cover and shield over the T-CON board carefully remove the flat cables connected to the T-CON board. I believe there are 4. The connectors have a lip on them to hold the cables so be careful.
Now reconnect the cables. Recheck the display now. If it has not corrected you can disconnect and reconnect again.
The very first solution I entered on fixya.com had essentially this same problem and solution.

If this does not solve the problem you can replace the T-CON board.

The T-CON board look something like;

2/5 of the screen has vertical lines multi colors. Is this a fixable problem?

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.

Further info, pics, comments, and updates on my Facebook page at

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 resolution updates will be on my Facebook page.

The right side of screen has no picture. There are multicolored vertical lines of all different colors that constantly change.Have updated the firmware but that didn't fix the problem. The picture comes...

This is something wrong with the t-con board, T-con board is a part of the panel, the part # is not available, but the Panel mode is LTA520HB0, part # 75011258 cost approx $3,210.13.

Vertical multicolored lines covering the whole screen

Just a shot in the dark, but if you are using component video cables, double check that they are in the correct inputs and outputs. If this doesn't work or you are not using component video cables then I don't have any other ideas as of now.
