HP Pavillion dv6000 wobbly screen?

I've had my laptop for almost two years now and i've noticed the screen is starting to wobble a bit. I'm not worried, coz I know this is something that happens from opening/closing so many times it wears out. My question is not WHY... but more HOW to fix it?! Is there a way to do it at home? or do you have to take it to a specialist? If so, is it an expensive ordeal!? I'm a student and would rather not have to pay too much as its not a desperate problem.
