Flat battery (or battery on its way out) can cause this.

I had a similar problem with my 40D. Canon diagnosed it as some type of electrical power supply issue.

Rule out the obvious. Mirror lock-up enabled? Inadvertent long shutter speed? Bad grip?

take the lens off and eyeball what happens when you push the shutter when you set shutterspeed to a few seconds. does the mirror flip up? does it stay up? can you see the shutter opening & closing?

The mirror flips up the sutter closes or opens but does not go the other why and the mirror stays up until you take bettery out and replace

maybe it's the dreaded 30D sticky button migrating to the 40D.
dirt causing contact to stay closed? keeping mirror up?

Did y ou get an ERR99?
When my shutter failed, it would click, then stop and ERR99 would be displayed. Had to have the shutter replaced by Canon. Worked great after that.
Note: I tried all the remedies that folks mentioned to me and now to you. Nothing helped so I sent it in. Thank goodness for warranty.

I have sent several items to them for repair. Typically they will repair you camera, clean it and update the firmware. So when you get it back, you should be good to go.
You could request a shutter count and see if they can retrieve it.

Good luck.
Mike
