Canon EOS D40

I have same problem with my 40D. Push the shutter button and it switches off. Have to remove the bettery for it to switch on again several times but still doesn't working. When I put battery back in the camera the access lamp blinks even though power switch is off. Any ideas??

Canon 40d will not take pictures

1) CF card in camera? Won't shoot without one

2) Does mirror go up?

3) Canon had a run of bad motors for this model - if mirror does not go up, then it is the mirror motor. If mirror goes up, shutter will not fire, press release again then the mirror goes down, the shutter motor is bad (same model motor). If mirror goes up, shutter fires, both blades travel together/no exposure, probably the shutter is bad.

My shutter won't fire using 18-55 lens, either on Manual, P or Auto mode. It is set to AF. But when lens is set to MF, shutter fires. I tried switching to another lens and shutter is perfectly fine.

I could be that your lens isn't focusing. If the Auto focus can't find something to focus on the shutter won't fire. If you are shooting in low light sometimes it has trouble try shooting something that is well lit. also your auto focus point may be somewhere other than the center. there is a button on the top of your camera that looks like this [ ][ ] [ ] [ ]
More or less that will switch where your focus point is. If you look in the view finder and see a red dot when you push on the shutter button that is your focus point. push the above button until the red dot is in the centre. that may fix your problem.

When I try to take a picture I get an error 99 message. Shooting is not possible turn off power switch or remove battery

Hiyou have very common problem of canon dslr product. usually problem come from defective shutter unit. However, there is cause from lens also. Would you remove lens and push shutter button? if no error 99, then the problem come from lens---usually power diaphragm control fpc defective.If shows error 99, then you have body problem. At this point, still you have to check more. please set camera M mode and bulb shutter speed, you have to look front of camera if mirror goes up and show to you picture sensor. would you tell me more later. Thanks and best regard!

On/off switch

The Dial on the top, there is a red icon, it is the OFF button, any other button is swithched ON. Altough it doesn't matter at all because the only way the camera is ON is whenever you are flashing or shooting, or presing the shutter button halfway.

Shutter don't stop halfway

Yes, there is a small 2-stage micro switch that needs to be replaced. 1st stage is permanently pressed and not switching/returning back due to so many time it's been pressed.
It just time. Switch is right under top cover.

Shutter problems

I am having a similar problem with my eos 100QD.
shutter opens, then stays open until I depress the shutter switch again.
Sometimes about half my photos are lost on a roll, but the other photos are fine (as would be expected from how the film is wound). This problem looks like it's caused by the shutter mechanism failing, a common problem with older camera and one that is often more expensive to repair than it is to replace the body.
