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!

I know not everyone has this ability, but if you can, go to a friend's
house and hook up an external monitor to your laptop. You may need to
use the function keys to switch from LCD to external, but if the lines
go away on the external, you have a bad LCD. If the line shows up
still on the external, then your problem is either:
a) video driver (free, easy fix)
b) bad inverter (video 'outputter') ...approximately $10-50/varies + labor costs to replace
c) bad video card/motherboard ...usually between $200-$400 + labor to replace
Hope this helps - please be sure to rate my answer :)

The lines appearing on your LCD means it has a defect on the screen.
There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color
You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.
2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.
3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.
If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost
Please rate this if it this helps.

Have you tried to connect your laptop to external monitor?
If you get normal picture on external monitor, then you need to replace LCD screen, but if you get same picture on external screen, then unfortunately you will need new motherboard, because graphics card is integrated to motherboard.
