So anyone know anything about computers?

I have an HP Pavilion dv7 latop and the screen colors are distorted. My screen becomes all these funny colors when I move it.

For example, the black becomes green and the white becomes slightly purple. (I can't post pictures since my camera isn't working right now. I'll try posting them up later.) 

I already had troubles with thsi latop with the charger not working.

Plus, thisalready happened to me once, the screen being distorted and what not.

I had my cousin fix it for me the first time, and I don't want to trouble him again, especially since he lives so far away now (two hourdrive now)

I remember he said that there was a wire that was being pinched inbetween the place where you open the screen and something else.

So how do I open up the screen to fix the wire? Anyone got any ideas?

Anything would be appreciated!: D
