Question about Canon EOS 40D Digital Camera
Did you figure out what this problem was? Exact same thing happens on my 40D. Push the shutter button and it switches off. Have to remove the battery for it to switch on again. After a few times of resetting it, it seems to start working fine for the rest of the day. It does however appear to be getting worse. It actually started doing this when I tried to use the pop up flash and now its moved to the shutter button. I'm about to send it in for repairs. Any ideas??
Before you send the camera in for repairs, try this free fix. The problem that you described is frequently battery related. Make sure that your batteries are the correct type for the camera, and that they are fresh/fully charged. If the batteries are OK, the problem may be due to corrosion on the contacts inside the camera. Remove the batteries and wipe the inside contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sand paper). Remove any residue that may have fallen into the battery compartment during cleaning, wipe the ends of the batteries, and replace them in the camera. This cleaning process works about 90% of the time, and I hope that it cures your problem.

Error 99 is mainly a design problem of eos 40d. i had the same problem after a 5k shots. it has 2 motors. 1 for mirror and 1 for shutter. most of the times these motor die early (like mine). first solution is giving approx.250 usd to canon to fix it (if out of warranty). other solution is buying your motor for less than 25 usd (from internet) and take it to a shop for fixing (approx 30 usd). total cost is 50-70 usd. i searched a lot and found this as the cheapest way!!
ps: i used nikon all the time for film cameras and bought a canon digital for the first time. now i understand how i mistaken... go nikon....

I'm having exactly the same problem - so far cleaning the battery doesn't make any difference. It's interesting that others are having such similar problems - how did you resolve it in the end?
