i read that if you are getting the dirty disc error a lot and you know it's not the games, then the lens or mirror may be dirty. so i followed the instructions on how to open the dvd drive and clean them, and so then after i put it back together, i got a dirty disc error message right away and it would not even play the disc. i tried many different discs and still got the same. so then i tried opening it back up and cleaning it again, and now it will not even recognize that a disc has been put in. it just sits at the dash. can someone please help?
