No you are incorrect, it MAY be an indication of a bad LCD panel if the problem exist in the LCD internally. Does the issue occur on a different computer? If so, read on. There are external vertical and horizontal IC driver's respectively driving a RGB grid, notice how the line colors do not stay the same in relation to the background? You should check the ribbon cable(s) corresponding to the location of the vertical lines whether on the left, middle, and/or right side that typically travel from the bottom of the LCD and terminating to the vertical IC driver on the PCB. This COULD be the issue because I have a Cintiq 18SX interactive pen display that exhibited a related problem. One way to know for certain is to push gently on the bezel below the lines, if you see the color change or lines go away, that is most certainly your problem. You may push on the ribbon cable connectors firmly after disassembly, if symptoms completely disappear you can try hot gluing or any other non-permanent means to fasten the connector down using firm clamping force and/or replace the ribbon cables. Hope this helps, please keep me updated if it does!

Hello,
These vertical line are possible causes of LCD cables from the graphics card. There is no easy fix for this issue and normally requires servicing or part replacement. Try to contact your TV support people or consult you local technicians to diagnose it properly as it might be also the panel itself failing.

Your screen is probably cracked did someone hit the screen with something? Push on the screen lightly next to one of the cracks does it get bigger near your finger? If so you will just have to deal with the lines or replace the TV as it is permanent damage with screen.

I have multi colored vertical lines across the entire screen. The menu screen is perfectly legible when selected on the remote and will go on and off like it is suppose to.


If this tv vertical colors lines problems happen by itself,tv problems not causes by u or an object by hitting forces to the tv LCD screen panel itself.The tv board that call the T-CON board it is dead,this board sit in the bottom in the middle of the LCD screen panel.Must be replaced the T-CON board to solve tv vertical colored vertical lines.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish T-CON board for the replacement.If causing by u or an object by hitting forces it to the LCD screen panel itself.The tv not worth a whole tv anymore,because by replacing the tv LCD screen panel will cost the same as a new tv.

Permanent Vertical Line on my Sony Bravia 46 inch LCD TV


What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.
