This Canonet QL25 does not cock the shutter: after winding the film lever, the film take-up spool moves as expected but when I press the shutter release just a faint click is heard and the shutter blades stay closed. This happens both with and without batteries. The diaphragm opens and closes as expected when I change apertures. Any sugestions for diagnosis and treatment?
And a more basic question - as it is probable that I will need to go through this: how do I remove the top, especially the winding lever ??
