Blu-ray problems

All of a sudden my ps3 slim 120gb version won't pick up blu ray disc. It reads games and normal dvds fine but it won't even pick up a blu ray disc, it does not show any kind of disc. In the system. I've tried 3 different blu ray disc. Same story with all of them. My ps3 is up to date on all updates. Any help would be appricated. Thanks.
If this is in the wrong forum my bad I'm new to these forums.
Thanks

Dumb question: You are looking under Video for the blu ray movie, yes?

Of course aaron :) . No problems now however. Called sony. All I had to do was go to video settings and change the 1080p setting from automatic to off then back to automatic. Works fine now. Glad I called before I cracked my ps3 open. :)

Good stuff.
