mine also got the same prob...now the ps3 is in sony singapore

from Djinn..

I think the cause of my disc detection failure is bcoz of switching on/off too often. Coz at that time i was fixing my speakers and av receivers..so..after fixing..i was testing my ps3...sound did not load..then off ps3..check cable..refix everything..and on ps3 again...these steps were done couple of time..then finally everything was working fine..was playing a bluray movie...suddenly it hang..i removed the disc..off the ps3 and on it again..from here onwards..it cannot detect the disc
