Timrhu, I'm intrigued by your method in dealing with problems associated with the reading of discs, and would be grateful if you could share a little of your knowledge by elaborating in more detail on your success with the can of compressed air that you've used. Or any other methods worth trying before sending the machine for lens replacement. Not too sure what equipment did you use to force compressed air to clean the lens though.
Cheers.
Cheers.
