Hassleblad 500c jamming issue

Effects

Looking for some help from Hassleblad owners here. I know I've read some people talking about them jamming before. Friend of mine was showing me his 500c and other equipment. He had an extension tube but didn't know what it was. He put it on the camera but when he removed it the shutter in the lens triggered. I now know that both the lens and the body have to be cocked to connect them together. The lens then wouldn't go back on the body as it wasn't cocked. Another lens was then put on the body and I think the body had been triggered so it didn't fit correctly together and now the lens can't be removed. The two parts that should connect together on the lens and body are not alligned together but side by side. I've tried to cock the shutter on the body using a screwdriver but it hasn't released the lens.
Has anyone had the same problem happen to them and managed to get it resolved? It's got the two of us pretty stressed out. Can anyone recommend someone to repair it if it's too complicated for us?

Seems like the same issue this guy had

Hey, if you are looking to get it unjammed shoot me a PM and Ill see what I can do. Seems to happen to a few people as I remember a short while back a tech in the US was talking about the same thing happening to a lens on a 500c.

It's kinda common from what I remember, but the extension ring thing probably complicates it a bit. My bronica has a similar snafu that can happen but it's relatively easy to fix. It appears that in some circumstances it'll require actual technical intervention to remedy , which is a bit nuts :eek:
Ping Al (fajitas) as well, I think he's encountered something similar before.

Thanks for the replies. I'll give Al a shout and see what he says. Have you ever fixed a Hassleblad before Zero?

Medium format film cameras aren't too common to come in so I haven't had a load in but a couple of Hasselblads came in (a 500c and a 500cm) with minor issues like that.
I have recently gotten to delve deep into a Mamiya RB67's internals and judging by the service manuals the mechanisms are pretty similar so it wouldn't be a bother especially the mounting mechanisms (plus being able to figure out mechanisms from drawings and without drawings is an essential skill to repairs).

He's dropped it in to a guy who repairs them quite a lot. Thanks for the help.
Hopefully it wont cost him too much.

i think (hence do not follow this advice) that you need to manipulate the screw inside the body, just under the throat, with the back removed.
sounds like the body is not cocked, so the mirror shouldn't be in the way?
