Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

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!

Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

Vertical hardly noticeable lines appearing on my samsung led tv


If you've cleaned the connexion between the motherboard and the display panel, I'm afraid the likely problem is the display panel.

If you have a friendly local repair shop, they might take a look at it and test with a replacement panel to diagnose the problem.

Sounds like a problem with the Vertical Video Card.

Have fun finding one. If your TV is still under warranty... send your TV off for repair.

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
