Hasselblad 500c w 150mm c lens self timer problem

According to my Hassy manual, before using the self timer the lens must be set to V and the pre-release under the winder must be released.
I did the pre-release, but now the shutter button will not depress(I tried both positions).
The dark slide is out.
The shutter is cocked.
There is no film in the camera back.
The shutter is closed.
Help!!!

Is the white dot visible on both the body and the back?

Functionally the pre-release does not have to be activated when utilising the self timer of the lens. You can pre-fire the mirror and capping plates first, or simply lift them when you start the timer running with the shutter release.

What *must* be utilised is the t switch around the shutter release. If it's not engaged, with (presumably, as you're using the timer) no finger pressure on the release, there will be no exposure on the film, because the capping plates will have already shut by the time the self timer trips the lens shutter.

First check the t switch. If no help remove the magazine and see if the capping plates are still open. Take it from there.

Assuming the timer is actually set it might have hung up. Try gently wiggling the arming lever to get it running. Tapping the lens barrel near the lever with a fingernail or knuckle can help to run it down. I am not entirely certain if the shutter release was already depressed but a Hassy won't let you depress the release if it has been fired once and not wound on. The t switch will also lock the release on. Hence checking the switch. If the capping plates are down it ought to have cycled and should be able to be wound. If they are still up and the t switch is not set—you have a problem!

Capping plates up.
Shutter closed.
Both white dots showing.
I'm not entirely sure where the lever was, but it won't fire in either position.
What will happen if I remove the lens? Will everything magically go back to normal and all I'll have to do is recheck the lens?

Also, will the camera fire if there is no film in the magazine?

I took the back off, pushed the release button and the shutter released.
I don't know why it didnt before.
I cocked the shutter, put the lens lever to V, moved the lever to T and tried to push the shutter release, but it won't move. I suppose maybe the self-timer may not work. Maybe time for a CLA.
Any insight other than the obvious that maybe I should use this camera enough that it's not a mystery every time I use it?

Take the film insert out of the back and let the counter reset. Most likely you have run the counter up to 12. After 12 it won’t let you release the shutter until the counter is reset to 1.

I think it's working.
Lens set to V.
Shutter release set to T.
Pushed shutter release, heard the barn doors and mirror open. About 8 seconds later I heard the shutter open and close(1/8 second).
But, when I tried to wind, it would not until I moved the release lever back to O. Then the mirror came back down and I could wind.
Is that how it's supposed to work?

Might have nailed it. Would explain why the body fired with the back off but not with it attached.

Almost. It is the photographer's finger on the release which keeps the capping plates (aka rear shutter) open. Let go of the release and the capping plates shut. Not a bad idea to get into the habit of using a little follow through with your finger for this reason. It's of no consequence at higher speeds but should you try to fire slower speeds with your finger for whatever reason if the shutter release is activated and then immediately returns up, the capping plates can beat the lens shutter at slower times.

Hence the T switch exists to keep the release mechanism active for Eg long exposures or when the self timer is set. Until it is returned to "O" the camera will not wind. It's not intended to. At that point the capping plates will shut. The mirror, however will not descend until the camera has been wound on. This model Hasselblad does not have an instant return mirror.

Don't ever try to remove (or attach) a lens unless both the body and lens are cocked. This means drive keys on both align with their red dots. Hasselblads are basically very reliable, but this point is something of *a big deal*.
