How can I fix my Emerson 3 Compact Disc Changer System?

I don't know how old your unit is but the laser scanner is good for anywhere from 7 to 15 years. The other thing that will cause your problem is the motor that spins the disc will occasionally go bad. This will cause the spin rate to be inconsistent and it will no longer consistently play your discs. You would be wise to simply replace the unit.
