How to clean the lense on your CD or DVD player

If your unit has some time on it it probably has a dirty lense on the laser assembly. This isn't difficult to clean but you must exercise care not to damage any components of the laser assembly.

Unplug the unit. Remove the top cover. If the disc drive has a cover, remove it. You should see the lense, which looks like a fish eye, looking up at you. The lense is mounted on a set of springs and will move around as you clean it. This is normal but do not apply anymore pressure than necessary.

The alcohol will do the work loosening the dirt. Using 200 proof grain alcohol, and commercial grade, lint free, cotton swabs, (available from any electronic parts supplier, here is an example www.mcmelectronic.com ), moisten swab and gently touch the lense while rotating the swab head.

Use a dry swab after the wet one to remove the loosened dirt. Blow dry the assembly with canned air, also available at MCM. Reassemble unit and you should have a working player.

In the unfortunate chance that you still are not reading discs you could have a defective or weak laser assembly. This would have to be replaced with a new unit. I hope this has helped you.
