Model CHM-S601. At first, chager loaded each disc in succession, would
not spin up, and proceeded to next disk. Opened it up to check laser
operation. Pickup bobs up and down and light comes on for each disc.
Gave the disc a spin and it spun up really fast, then the changer tried
to change discs while it was spinning at high speed. Now each disc
will spin (but at high speed) for 20 s or so and then proceed to the
next. Any suggestions? Thanks.
