How to differentiate between a dirty PS3 BLUE RAY DISK AND A BROKEN DISK DRIVE?

Question

I HAVE BOUGHT A BROKEN PS3 WHICH I'M PLANNING TO FIX MYSELF BECAUSE SONY ARE ASKING A LOT TO FIX THIS. THE PS3 WON'T READ ANY TYPES OF CD OR DVD OR GAMES. BUT TURNS OKAY AND EVERYTHING ELSE WORKS FINE. THE GUY THAT HAD THIS SAID THAT ONE DAY HE INSERTED A DIRTY CD, YOU THINK THAT THAT COULD BE THE PROBLEM? THANKS IN ADVANCED.

Answer 1

Might just need to wipe the lens. It is possible if the CD was very dirty, that it transferred some of it on to the lens. Use a Q tip.

Answer 2

Try using lens cleaner. Don't go for cheap ones - they can damage the lens.
