500C/M stuck mirror

Hi all,
I absentmindedly pressed the shutter on my 500C/M with neither lens nor back attached. The aux shutter is open and the mirror is stuck about a cm from the top of the front opening.

Trying to resolve it I did something stupid and attached my CF60 after having turned the thing on the front that connects to the lens and pressed the shutter hoping it would resolve the problem. The result is that the lens is stuck.

Any one have an idea of how how I get out of this mess?


Edit: I should add that I shot two rolls yesterday without any hickups.

Thanks,
Carl
 
So I managed to get it unstuck and get the lens off by touching something that released the mirror inside the body.

I attached another lens and wound the shutter. Works as intended. Then I tripped the shutter again and the mirror is now stuck again in the fully open position. The lens was set to 'B' for some reason. The central shutter is closed, but the aux shutter is open and the 'pin' on the lower right hand side of the body is out.

Any tips?

Found the little screw inside the body that winds the drive shaft turned it so I got the lens off. Mirror still stuck.
 
Sounds like a broken spring or damaged component of the mirror mechanism.
Not something for amateur repairmen.

I recommend a professional check up/repair of the body.
If you are unable to find a local repair shop with Hasselblad experience try
David Knapman in Landvetter, Sweden.

Glad you managed to get the camera going again.

Keep in mind these problems are often a sign the body could do with a service by a qualified technician.

Paul,
Yes, I have thought about it. I see some foam that needs replacing in there too. I was planning to get it to Interfoto before their V-system tech retired at the end of April, but it didn't happen. Now it has to go (home) to Sweden. I think.

Pieces of foam floating around indicate the camera needs a full service.
Keep in mind the foam has influence on the position of the mirror meaning what you see on your focusing screen may not relate to what is exposed to the film plane.

Thanks, for your insight Paul, very helpful as always. For now it seems accurate enough for my purposes and I hope it will stay that way for a few months more. I souped one of the rolls from Saturday yesterday that has some fairly tight shots with the CF60 and they are as I remember them. Being an RF shooter mostly I usually tend to frame a little wider than strictly necessary. I plan to have it serviced after my summer vacation. Don't want to be without it then. The camera is from 1982 so it isn't really any wonder it needs a CLA.
Cheers,
Carl

Do keep in mind it is the focus that is influenced by the mirror not being at a 45 degree angle. The foam mentioned keeps the mirror properly positioned. Assuming the foam is in good condition, it goes without saying.

Sorry Carl, I disagree.
We aim to get the best from our gear.
The foam strips for the mirror deteriorate gradually but their influence on accurate focus is substantial.
This is especially the case with longer lenses used with full aperture.

There are two sections of foam: one to catch the mirror in the down position, the other stops the mirror after it swings up.
Release the mirror without foam and you are ready to collect pieces of a broken mirror.
