I can solve this i think but am pretty busy right now. It's also cheap
and usually easy. If you can carefully open the shell (body) , with it
unplugged of course,note where all the thin wires belong for when you
put it together again. Assuming you have the projector open and on its
back, look near the top, centre roughly. You'll see a white, thick gear
that gets driven by a long worm gear/pulley that is driven by the motor
belt. Above the thick gear is a silver-grey metal catch or "trigger"
and resting on - or near it- will be a (usually) copper coloured thin
metal "finger.
in normal operation this finger catches on the grey metal trigger which
flips into position and catches the clutch built into that thick gear.
When you activate the slide advance, the solenoid, for a moment, pulls
the finger off the trigger which moves the triger which allows the
clutch to engage and turn the thick gear, driving the mechanism. What's
happening is that over time the light grease has thickened and the
trigger is not engaging properly.
In some cases, all you need to do is just activate that slide advance a
couple of dozen times, or let it keep advancing a few dozen times. You
might try this before takign it apart. It selldom is enough but might
be. usually though you'll need to look carefully to the pivot point of
that grey metal trigger. If you have any contact cleaner for
electronics (degreaser) get a little on and behind the rivent that
holds that trigger and let's it pivot. With your finger, getnly rock
the trigger back and forth. Repeat a few times if necessary as that
cleaner evaporates quickly. If you don't have such cleaner, you can use
a bit of WD-40 or alcohol can sometimes do the trick. Rubbing, not
whiskey! Whatever you use to clean out the old, dried lubricant there,
be careful not to let it get into other areas of the mechanism!
Especially the WD 40 whihc has both grease cutter and oil. Oil in the
wong places will give you bigger problems.
Eventually the trigger should move very easily and return to position
quickly when you release it. Now you want to put a drop or two only on
that pivot point, of the lightest oil you can find. Most easily
accessed is light sewing machine oil.
You may decide to plug in the projector now -remove the lamp first. it
is dnagerous at this point so be careful, or before you plug it in, put
the shell cover back on. If you cover it hough, you can't see what's
happening. In any case, run it, advance the slides via the remote
preferably, a few times and unplug it.Hopefully it's stopped advancing
continuously by now.
Take a look at the point where the "finger" engages the "trigger". You
want to be careful not to bend the finger or things'll get out of
whack.But IF you can (unplugged again!) spare just a tiny bit of grease
from that thick gear, put just a bit on the trigger where the finger
rests. If you can locate a clear coloured teflon added lubricant called
Super-lube (also sold under at elast one other brand name I can't
recall), that is the stuff Kodak used.
Reassemble carefully and try 'er out. If you run into any problems,
give me a shout at

you don't get spammed out.
