cd player not reading a disc? Laser dirty?

Hey, thanks Mental. Never thought of looking for that on u-toob. My 3910 gets erratic disk read errors and eventually stops reading altogether. I had to bring it in for service, but I bet I can follow a DIY video. I'll give it a try.

You can buy a laser lens cleaning cd disc at best buy for about 10 bucks. Just a series of soft little brushes on the disc. They work pretty good. I'd try that before anything else.

FWIW. The problem is worse when the unit is well warmed up, say after playing a dvd.
