The shutter keeps getting stuck and I can not take photos. How do you prevent or how to unstuck it.

It sounds as if the drive belt or wheel that controls the carriage has perished and failed. There is normally a micro switch on the side or rear of the tray, that senses the presents of a casset. If it is closed with stikky tape or clay you may be able to simulate a casset in the machine and with manual force help the casset to open or close. alternatively a small lamp in the centre of the tray senses the tape. then you have to cover the lamp or two sensors on left and right side of the tray, to prevent detection of the broken or missing tape.

Could be related to a stuck shutter which is a common problem with this camera. Check that all physical parts are moving and do an unstuck process to free the shutter if this is the issue. See the link for more details:

Try this: Give the shutter button a few quick, hard pokes with your finger. Don't be shy, you've got to give it a few good jabs. This can get the mirror unstuck. It's helped me before...

I have a Ts3 which is very similar to your model. I had this happen today only after having this camera for 1 week. When I powered it on it would immediately focus lock and all other buttons were not usable expect for shutter button. I found some fine sand had wedged its way into the shutter button which was preventing it from fully releasing. In other words, it was acting as if it was 1/2 depressed getting ready to take a photo.. So the solution? I got the little brush out that comes with the camera and got the sand out. All works fine now.

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

Sounds like a dead CCD. Contact your local Canon service center.

First make sure the mode selector dial is set to the red camera without an M next to it (ie you're in Auto mode and NOT in manual mode). If so...

Now the A410 is not capable of taking 15 second exposures as recommended for the fix. Instead try setting the camera to manual mode, turn off the flash, got to a darkened room, and take a picture. Open the battery door while the red and yellow light are flashing. If after many tries this does not work, then consider trying Fix #5a on the site. But do so with the camera turned off and the lens retracted to lessen the chance of damaging the lens mechanism.

First make sure that you're in full auto mode and not in manual or any of the special scene modes. Check your rotating mode dial that its set to the first red camera by the blue arrow.

If you already are and were in auto, then a stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure.

Now the A460 is not capable of taking 15 second exposures as recommended for the fix. Instead try setting the camera to manual mode, turn off the flash, got to a darkened room, and take a picture. Open the battery door while the red and yellow light are flashing. Repeat as the fix recommends, but please note that there may be only a small hope that this will work as the shutter may be stuck in the open position. This is harder to get unstuck than a closed shutter.

Are you sure that you are in full "auto" mode when you are taking your pictures? Make sure that the mode selector is set to the first red camera (without the M) right next to the little blue arrow.

Your camera is not capable of taking 15 second exposures. Instead try putting it in manual mode, turn off the flash, take it in a darkened room, take the picture, and open the battery door while the red and yellow lights are blinking. Give it several tries, but note that the chances may be very slim for success as the shutter symptoms suggest that it is stuck open.

This sounds like the mechanism has worn. It is a straight forward service centre procedure, I wouldn't recommend trying to do anything that will make it worse. Leave it to Nikons engineers.
