Can someone help me. My PlayStation 3 started to have some problems reading some DVD's and blu-ray. Right now it will only read music cd's and some DVD'S. I'm was thinking about replacing the laser to see if this fixes the problem, but I need to know for sure before I spend $80 to replace it. Last night I was about to play a Christmas cartoon on the PlayStation 3 without any problems, today I tried to play the Simpsons season 5 DVD and it will not read it. It will still play the Christmas Cartoon, and an music Disc Great. Just will not play PlayStation 1 and 3 games, blu-ray and some DVD's. This is the 40GB NTSC model.
