I'm seeking for some ideas on how to repair my NEC CDROM2. When I first got it, testing it as a CD player with no briefcase attached, I would only get a 0 displayed on the LCD, but no movement. I have changed the middle gear and greased the spindle. Now the CDROM laser moves correctly and I can hear it focusing, but the CD won't spin.
My ideas are:
- possible PSU not delivering enough power (I'm using an universal PSU)
- broken laser block (how to check for this?)
- needed potentiometers adjusting
Any ideas on how to troubleshoot it?
Thanks a lot for any help
