Display has lines that run through it

My Acer laptop display first had a (horizontal) line going through it and the cursor/mouse would not move. The laptop itself is stationary, with the exception of opening and closing the display screen. It sits on a desk... The screen started to get a thin line through it, but, when the screen was moved either forward or back it would resolve itself. Now the screen has several lines through is (all horizontal) and then the lines begin to increase in width and kind of take over the screen. The mouse/cursor will not work unless the screen is clear and without lines, which now doesn't happen at all. I can't get to anything, unless I hook my laptop up to my desktop screen.

Any help would be appreciated... Thanks
