Mark III 5D

My shutter will not open when I try to look through my Viewfinder. Please help! I can take pictures through the screen but when I switch back to the view finder, it is black.

Did you remove your lens and look in the mirror box?

[KamdynFuller]

Yes, the Shutter is closed.

When you open the camera, is the shutter exposed immediately?  If so, then your mirror is stuck in the up position.

[KamdynFuller]

It seems like the Shutter is getting jammed. I can touch it and it will come back down, but as soon as it takes a picture and goes back up it jams again.

[Tronhard]

That would be normal if the camera is stuck in back in live view mode.  If you have not done so, I would definitely do a camera settings reset.   Can you confirm that the mirror, normally in front of the shutter, is always in the up position?  Don't try to force it back down!!!!

[KamdynFuller]

I have already reset the camera settings. I did not force it back down if I barely touch it, it comes down on its own and I can finally see out of the viewfinder. Once I click the button and take a picture, it takes the picture but the shutter is closed and I am no longer able to see out of the viewfinder.

Looks like you need a mirror box repair.
