My trusty old Pioneer CLD-704 LD player has begun giving a "no disc" error everytime a CD or LD is inserted for play. I popped the top off last night and what happens is the laser mechanism first moves to the outer LD position and lifts into place. Finding nothing there it then moves in to the CD position and lifts into place (I'm testing with a CD so I can see what's happening underneath). It doesn't recognize a disc there either so it moves back out to the standby position and gives the "no disc" error. At no point does the disc begin spinning. Does disc spin-up happen before or after it starts looking for a disc? If I knew that then I could isolate whether it's the motor or some other part that's gone south. Any help would be most appreciated as I'm hoping to get this thing running again.
