Yeah my PS2 just refuses to play games, it usually takes about 15+ mins of putting it back in the system for it to be able to read a disc. Every time it comes up with "Cannot read disc"

It's one of the original one's (I got it right when it first came out) so it's pretty old, and I know it's not the discs because the mini-PS2 at home (which i shall be stealing in a month or two) can read them fine.

So is there any quick, easy fix to make it read discs or am I doomed to dealing with this until I go back home and switch the PS2's?
