Was playing Uncharted 3 (goty edition) co-op, the game froze at the loading screen. Then I turned off the system...the PS3 beeped while turing itself off (an improper shut down maybe). After that, the PS3 stopped reading any disc (CD, DVD, BD).
It accepts the disc and after seconds it makes the ejecting sound.
I did the Restore File System thing but no luck.
I'm not careless; I keep the device clean and my discs aren't scratched.
Should I use the known lens cleaner?
Factory rest will help?
PS. this has the very same issue here:
I bought the device in Jan 2010.
Run through the steps in this guide and let me know if you continue to have problems.
