Audio Systems: CD Changer repair, circuit city, disk error

Question
I am having a problem with my 6 disk CD changer in my mountaineer. It is a stock alpine changer from 2000. When I put a CD in it and try to play, it comes up with disk error. I have tried both burned and standard audio CDs. None work. I know that this is vague, but I've had this problem with another changer and didn't know if it was a tell tale sign of something.

Answer
All too common in my experience with changers.

Usually, it is a tell tale that it's time for a new one.
A Disk preventive cleaning device/regime can help extend the life, but once they error, it is usualy cheaper to replace than to repair them.
Of course, now that we can put 120 tunes on one cd (MP3 capable indash CD player), the single disk units are not a bad option starting around 80.00 at your local Walmart and Circuit City.
