Well I have 2 PS3's one which works absolutely fine and is a slimline and the other is an 80gb one which doesn't read disks, I've tried CD/DVD/BluRays to see if it will read any of them and it doesn't my brother had the same problem but his read CD's and DVD's. I was thinking about putting it on eBay for parts or spares but if anyone else has any ideas first then fire away
