If you mind the lines and if they are too big replacing the screen will be very expensive and there is no way to repair your current display. The way I see it if you pay more 65% of the current value of your TV is too much. You may be able to find a new TV for as much as the repair cost.

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

Vertical colour lines on whole screen


The problem is that the panel has failed. Apparently this is a common problem with LCD TV's between 18 mths and 3 yrs old. If it survives over 3 yrs it is likely to last for a few years longer. The cost of replacing the panel is more than a replacement TV!

Blue line - screen


Your control board and address circuits need to be examined. This could be a component problem or a simple fix such as installing a new ribbon cable from the control board too the address circuits on the LCD panel itself. To do this would require a technician, but before this issue gets worse you should have it repaired.....check to see if its under warranty.

Some people have tapped the back of their tv and got rid of vertical line interference. But , I wouldn't suggest that method.......

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 horizontal lines on Sony KLV-26HG2 LCD TV screen


Hello,

If you can fix it by yourself, there is a problem in horizontal circuit panel, you need to check that in series because the part appear visbly good but when tested by the exact tester you register busted. that should be replaced immediately. Check also the vertical panel parts of the circuit. but if hard you do the job you may consult the service center of your TV or the vendor of the TV.

ps. please don't rate me if you are not convince of my suggestion.

best regards, melnavz
