PS3 not recognising BDs or DVDs.

[Bullseye]

Its an original PS3 40gig machine. Have had it almost two years with no issues until recently. About a week ago while trying to play a movie "King Kong" it played for about 15minutes and then the picture froze. I started a thread here and people recommended I check the FW which I did. At the time it was 3.01. Its not running the most up to date version. I can go on line and all the other things the player does but it won't recognise a BD disc or even a DVD disc.

Anyone else have this problem? Is there a solution?

Initially it loaded the disc this morning (Casino Royal) and I got as far as the menu. Went through the menu fine. But when I hit play movie screen went blank. Checked the disc (clean). Tried another disc. Player said "No media loaded"???

Oh and I just set up wireless connection through my router. All working fine.
