Hasselblad 1600F shutter release problem

I recently acquired a nice Hasselblad 1600F with the 75mm Ektar. The problem is when winding it, the mirror flips down, which is normal, but at the end of the winding of each frame, the mirror flips back up and the shutter releases, without even my having touched the shutter release button.

The shutter speeds seem accurate and the focal plane shutter curtains are not damaged.
The small red/white window which indicates that the shutter is cocked or uncocked never turns red, indicating cocked.
I guess that's why the shutter release button does nothing at all.

Any ideas?
Is this something that is a relatively easy fix?
If not, who can you recommend to service a Hasselblad 1600F?

Hasselblad no longer services these vintage cameras and my own repairman has no experience with focal plane Hasselblads.

Thanks.​

It is not only a focal plane Hasselblad, but one orphaned more than half a century ago - Kiev 88 experts might be a better address for Hasselblad 1000 series repairs than anybody servicing Hasselblad 2xx(x) cameras, as Kiev copied the original focal plane Hasselblads when their patents ran out, while Hasselblad's own return to focal plane shutters (after twenty years leaf shutter only) was a completely new design with barely anything in common with the old.

As far as the problem goes, check whether something internal to the release knob or cable release socket is stuck - that might be a DIY repair. If the shutter release catch is worn or damaged, it may be a matter for some service person that can machine a replacement part...
