it's just not displaying what BD-ROM i've inserted.
My PS3 did the same, as has a few friends. The problem that plagued the PS2 seems to be back, everything works great, then the laser/drive just dies for no apparent reason. I think I owned about 5 PS2s in total all died due to this problem

I phoned sony, made a fuss and they picked mine up and replaced / repaired it. Took a while though.
