White Big Horizontal Line in My LCD Monitor

Asked By adriel roberts 20 points N/A Posted on - 04/13/2012

I am using a Samsung SyncMaster 23 inch LCD screen for about 2 years now. I am a bit contented on how crisp the images are and is very useful for my photo editing work. But now my LCD screen has become an annoyance because a horizontal white line appears on the right part of my LCD screen. For every task I do in the computer, that white line exists. Even when I just open the LCD, not the computer, the white line is there.

How can I get rid of the horizontal white line in my LCD monitor?

Mr. Roberts,

I think it’s time to change your LCD. There is a problem with your LCD panel screen there is not any problem with software or CPU. And this problem will continue and this white line will start to increase.

Actually there are two parts of an LCD. One is LCD controller board and the other is LCD panel screen. It is really hard to repair an LCD panel screen or I should say that it’s impossible to repair.

Either buy a new LCD or just go to nearby repairing shop if he could help you. Anyways it’s a hardware fault not from software. You have to replace it or get it repaired. By replacing the whole LCD screen panel this can be settled.

Well here's what you need to do first, you need to check if it is the LCD that has a problem or it is caused by your video card and video driver. So first things first, try to check the LCD if it is good by plugging it on a different computer. Check if you get to see Lines as well. If you see lines when you plug it into a different computer, chances are your LCD has an issue and you need to have it repaired or replaced if it is in warranty. If you don't see lines, then that is good news, meaning there is no issue with your LCD.



Now, test a known good monitor on your computer. You can borrow an ordinary CRT monitor or another LCD from a friend, just try checking if you still see lines even when you are using a known good monitor. If you do see the same issue even when you are using a different monitor –> then it clearly indicates that you have another possible part at fault which is either the video card or just the video driver. Try uninstalling and reinstalling your video card driver and if still no go, then try swapping your system with a known good video card.



Hopefully you get to resolve you issue and that your LCD and your entire system is still in warranty.
