PS3 lens problem (cant read any discs)

[rukusa]

this usually happens if you insert discs incorrectly or operate the PS3 the wrong way.

Many people have a tendency to just reset the console when the game youre playing for example freezes.

To avoid damage to the lense you have eject the disc first before you reset the PS3. At least that way you will avoid alot less damage to the blu-ray lense.
