There can be 3 possible reasons for this
1)Screen connector cable is loose. You can try to re-seat it and see if works.
2)display card problem. Connect your laptop to an external monitor and see if the problem persists. If it does not then
3)You will need to get a replacement LCD screen.
Hope this helps!

Hi mikenstacy

Try to connect a normal desktop monitor to the laptop (there will be one vga port where you can connect the monitor) and if you see those lines on external monitor as well then most probably video card has gone bad (you can try to reinstall video drivers in this case) if those lilnes are not there on external monitor then problem is with your LCD so if system is in warranty then get it replaced other wise get in touch with local compter shop and get it replaced.

let me know if this helped

At first glance, I'd say "bad video/motherboard" ...however, when you hook up an external monitor, you also need to first switch into "external LCD" mode. On the Dell laptop, hit FN and F8 I believe to switch between LCD and external. It will go through several modes...LCD only, external only, neither, and both. Keep switching until you see something on the external.

If you never see output on the external, you've got a video/motherboard problem. If under warranty, contact Dell and place a support call.

If not under warranty, you're looking at anywhere from $200-$400 for a new motherboard, plus labor for someone to install it.

Hope this helps - remember to rate :)

I had the same problem. You need a new graphics card.

Had the same problem. Fixed it though. Here's how:
You'll notice that the screen comes back to life if you press down on the very top of the green line. This is because a controller circuit board behind the LCD screen (at the top) is pressure fit flat-surface-to-flat surface to the contacts on the back of the LCD. Eventually, the sticky substance that holds this circuit board in place wears thin, collects dust, etc.. and the connection between the circuit board and the lcd contact is lost. The line appears where this break in contact has occured. 
So, the solution is to increase the pressure at that point to reestablish the connection. I wasn't able to remove the circuit board to clean beneath it as it seemed too likely to cause damage. Nor would I have had the right adhesive to connect it back, so I simply removed the LCD and put a bunch of tape at that point so that it would "push" with a little more pressure when screwed back into place. Worked great.
To remove the LCD, pull off the 6 feet around the screen. Remove the screws behind them. Carefully pry off bezel with a small flathead screwdriver working your way around it. Once removed there are simply 4 screws on the left and 4 more on the right of the LCD to remove. Pull out screen carefully and start stacking bits of tape on the spot where pressure seems to work best. Put it back in and see if you've made any difference. I did this with the computer on so I could verify my results. Just be careful not to short out any naked contacts.
If this doesn't work for you, at least you'll know you just need to replace the LCD, not the video card. Easily found on ebay.
