Laseractive doesn't spin Mega CD disks was Re: Pioneer Laseractive Repair Info

[hardgb]

Hi, guys, I have a Pioneer LaserActive with Pack MegaDrive.
It works perfectly with the megadrive Pack but he did not preduz discs.
I opened it and noticed that it does not spin the discs. Apparently everything else works normally (gears, optical drive ...) but does not spin discs.
What think you can be? Please I need help.
