My PS3 isn't reading any dvd, cd, or bluray....?

If you can hear the disc spinning but it still won't read then its a lens problem but if the game is not even spinning at all than you may need a new blu ray drive. Currently I have two PS3s my main one just died on and am currently working on replacing the lens and the other one I just bought from someone locally for $30 bucks. Thier lens went out to but they think its busted and sold it. I can now buy a new lens for about $50 and I would have a nice PS3 for $80. LOL pretty sweet. Hope this info helped.
