try this ..there are instructions about functions and how to handle and use it ..

The battery in the film back is only used to supply power when the back is off the camera, when it is on the body power is supplied by the six batteries in the body so try them and also make sure the film insert is properly seated.

Thanks & waiting for your feedback.

I've got the same problem :-( Help would be appreciated.

Damaged the gear which is mounted at bottom of focasing knob, ni problem if it removed only fine focas is not work.

There is good chance that the back needs a spring replaced. I've seen them fail many times.

have you tried Mamiya's website?
they have some instruction manuals to download.

Sounds like the film has come loose. Either it's not properly loaded or it has cut. Try to open the camera in a dark room and feel your way thru the inside of the film track to assure the situation.

I have a PDF version I'd be willing to send you if you still need it. What's your email address?

Did you made sure the dark slide was removed? Check to see that the firing pins on the camera back are coming through the revolving bracket okay and that they are engaging the pin on the film back (left side). Is there film loaded? You can check without film if you have the multi-exposure lever engaged (red spot visible) and dark slide pulled out.

These lenses arn't designed to be taken apart.

A camera specialist may help but they should alwys be kept dry and at room temp never warm and humid. Silicate gel in your storage bag also prevents this from happening.

Good luck

This is not the best solution as it indicates a faulty film back. The film should advance without resorting to activating the film-wind release lever. That is only for intentionally advancing a partially exposed roll of film. Make sure the multi-exposure lever is not engaged and that the counter does advance and the red mark disappears as you advance to an unexposed frame.

Very likely that some of the teeth on an internal gear are broken, or stripped. It could have been jarred or over time, just gotten brittle if its plastic.
Another poss. is that the shutter lubrication could have dried out = more resistance = snap.
sounds like it gonna require taking apart. At Minimum, a CLA, otherwise, parts too.

A yellow led indicates the wind lever isn't cocked, or a weak spring hasn't returned it to the fully up position. A red led says pull out the dark slide.

Needs film in the filmback works fine. With no film will only work in M mode (multiple exposure)
