But first you can press gently at the back of the laptop on various spots and see if the lines go away or if they get worse. Hold the LCD with both hands on both sides, then gently move it back/forth in opposite motions and see if the lines get worse or if they go away.

If the unit is not under warranty anymore you could open the LCD and reseat the LCD cable. To do this remove the rubber buttons that are located on the front LCD cover - there should be 4 or 6 or 8. Then you should see the screws. Unscrew them all. Now you can remove the front cover by taking it off gently.

Depending on the model, you need to remove the screw that hold the LCD to the backcover so you can seperate the LCD from the backcover to reseat the LCD cable on the LCD.

After reseating the cable (removing it from the LCD cable slot and connecting it again) you can close the unit.Reseat the LCD cable on the mainboard as well and see if that helps.

Furthermore if all this reseating pulling and pressing didn't help, test the unit by connecting a external monitor or LCD. If it gives a clear good picture on your external, then you know your LCD might be faulty.

Blue vertical lines

Hi, I am sorry you are having issues with your graphics card.

Yes the oven trick does work but it is only temporary and you will have to do that process over and over until the card just all out quits responding. Once a GPU begins to display multicolored or blue lines across the monitor its time to put it out to pasture so to speak.

Screen is going crazy

Okay, it could be two things, 1.) Your graphics card is either overheated or going out. 2.) it's possible you have a messed up display screen. I'd try looking at your computer display settings and see if you can calibrate the color on your screen to see if it helps or not.

If you need further help, I’m available over the phone at


The left side of my laptop screen wet all white with red green yellow blue lines running veretical lines running through it. looks like someone spilled paint on it


Vertical lines are usually caused by 2 things, either your graphics card is going bad or your screen is going bad. How you check if it is your graphics card is by plugging it into an external monitor (if you have one).
If the lines still appear on the external monitor then you know its the graphics card going bad, which isn't probably worth fixing these days if you take into account how must laptop pricing has dropped.

I hope this helps.

Best of luck!!

I have vertical lines on screen I have changed the whole screen assembley but lines are still thers , exactly in same place

Hey There,

The reason this happens is because the graphics card is either loose burned out or jsut needs to be cleaned... to clean it use a pencil rubber in the gold tips that connect it, blow on the card to remove any dust build ups and reconnect the graphics card when done (make sure its clipped in properly).... different brands of computers will do different things such as the different coloured lines and screens flashing red. My dell latitude 630 had green and blue verticle lines. Just follow what i said and it should be fine

Hope this will help you in Resolving the issue with the vertical Lines on the screen.

Vertical lines in lcd

sounds like your graphic card is bad, try first to download updated drivers from the internet and see what happens, also try to connect an external monitor and see what happens.

Thick Vertical White Line Through My LCD Monitor!!!

You can check if it is a screen or not. Connect another screen to your laptop. If you dont have anotherone you can use your friends screen or go to the nerest computer store and test one there. That way you know 100% it is the screen or another thing: video card wireing...
