Vertical line on side of LCD TV

My Sony KLV-40S200A TV has a vertical line on the right hand side of the screen, about an inch off the edge. The line extends from the top to about 3-quarters of the display going down. The top color is blue, and gradually changes in the middle to red and the bottom is kind of pink. It started with just a small like about 5 inches in length at the center, and over time it has extended to the top of the TV.

TV was acquired summer of 2007, and it just appeared a couple of months ago.

Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!

Sony BRAVIA KLV-37U300A 37 In LCD TV with shadow background on screen


That sounds like a defective LCD panel tab, Sony's and Samsungs are notorious for this problem. Does the problem go away when the set warms up or when you tap the screen?

Hi there are a few things that could be bad on this TV. the first thing I would check is the T-con board if that's not the problem then the signal board and last the screen itself. If you are planing on doing it yourself you can get parts from www.interliquidparts.com

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.

Sony Bravia KLV-40U100M-screen is distorted, overlay or various vertical lines


The resolution on this was to check the surge protector the television was plugged into. Once we unplugged and plugged into another surge protector, the screen went back to normal and the appearance was great. We believe this was due to one of the resistors within the surge protector may have become faulty.

Dark vertical line(s) on Lcd tv


Most likely it's the LCD panel failure. You can replace the panel if you can find a spare part. But the new panel may cost you as much as to buy a new tv. Hope that will help you.
