Answer to: How do I fix playstation 3 it wont play discsThis problem is caused by sony's crapy system. It happens when you install a new game and then run a system update. Next time you start the system it stops playing game discs. I had this happen 3 times already to my system. Even though it is Sony's fault they refuse to fix it and want $150 for the repair. My system has been a $700 paper weight for most of the time since I bought it on launch day.
