I just got a brand new 20 GB PS3 and it was working fine for about 2 weeks then I updated the systems firmware to 1.51. Now nothing works. It won't boot up any discs. Blu-Ray movies and games, PS1 or PS2 games nothing. It's not even recognizing them. I put in a movie or game and nothing pops up under the game or video tab. Anyone know what's wrong or how to fix it?
