With HP the verticle lines are caused by the monitor itself not the video card...which will mostlikely fail anyways. Your problem is that your cable that is connected to *********** board is damaged.
You may have to remove your lcd monitor and unplug and plug it in your laptop, firmly but everything should fit and dont force anything.

Plug in a normal computer CRT or LCD monitor to the blue VGA output on the laptop. If you do not get lines on the external monitor, then the LCD is the problem. If you do then it is the video card.

If it is the video card then you either have to have the motherboard replaced or have the video chip reworked.

Let us know if you have something more to know else accept the suggestion.
Thank You for contacting

White line vertically on my monitor just showed up but computer seems fine

The problem seems to affect only the monitor whih means that all of your data is safe (in any case make a backup, you never know).
You should bring your computer to repair service. If your computer is in warranty you will have a free repair service.

Hi, My name is Joseph. My HP DV9930us is not displaying anything except some blurry light and when i connect it to an external monitor, it shows lines vertically. Anyone has a good suggestion for me. I...

Joseph, I've had this problem more than once by this laptop. Unfortunately this is a known issue and the only way to fix it is by sending it in. This usually indicates a motherboard / video display driver failure. Mine is still under warranty so I send mine in for repair whenever it happens.

First one and now 2 vertical lines on my HP f2105 monitor. Would this be the actual screen or a component that drives it? Thanks

Move the mouse cursor across the lines then check if it shows up fine. If it shows up fine, the problem is in the video card itself, not the monitor. It can be caused by VRAM or GPU overheating. Clean the video card thoroughly. Using a compressed air is a good alternative.

You could have a faulty LCD screen or a faulty video cable/connector.
Try reseating the video cable/connector that connects to the motherboard. If this doesn't work a replacement LCD screen may be required.
Check LCD Parts for parts and repair service, Use this link.

Black screen with vertical lines through it

Could be faulty graphics chip or faulty screen. If you can hook up external monitor and picture is fine then probably faulty screen. If external monitor shows same problem the faulty graphics chip. Take to repair shop and let them have a look.

Vertical lines in my laptop screen

Hi, that sounds like the integerated video graphics is going bad and it's not actually the screen. the zd7000's were known for video graphics failure. there was a lawsuit filed against hp for the zd models about a year ago to get a free motherboard replacement because of the video issue but it's too late to send it in now for the free repair. the zd models don't have a replacable video card in them like most laptops which the only way to fix the problem ould be to purchase another motherboard, you could try ebay but they're not that cheap.
