RE: [Rollei] Rollei P66S Repairs

I had that failure mode on a Rollei 35mm projector and if I'm 
not wrong, the basic layout of all Rollei projectors 
of this age is the same (excluding the Rolleivision). So 
maybe this helps:
The slide transport is triggered by a solenoid that engages a 
clutch. The clutch then stays engaged for one turn, i.e. one 
slide transport. After letting go the transport button on the 
remote control the solenoid is released and the clutch is 
pulled back by a spring. In my case the clutch operation was 
a little stiff and the spring could not pull the clutch back -
 it stayed engaged for another turn and another and another...

Watch out for a solenoid operating when pushing the transport 
button and check what happens when the solenoid is released.

Do not touch any of the funny-coloured cables inside the 
projector when it is working...
