Camera powers down after lens comes out

The S2 IS is a very nice camera, but is known to be susceptible to stuck shutter problems. 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, sometimes with lines, 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.

Hi,

Based on the information you've provided, it seems that the Lens Mechanism of the Camera is damaged when it fell down. The Lens of the Camera is not focusing properly while capturing the images. As the issue is with the lens mechanism, the previously captured images are displaying normally. I suggest that you try resetting the Camera and check if the issue can be resolved.

Performing a manual power reset

Turn off the camera.

Remove the battery pack.

Press and hold the power button for 30 seconds.

Allow the camera to remain without power for 60 seconds.

Reinsert the battery pack.

Turn on the camera.

To reset the Camera back to factory default, select the INITIALIZE Option from the SET UP1 Menu of the Camera to OK.This will set the user defined settings back to factory default. The images and videos will not get deleted.

If the issue persists, service may be required.

Thanks for contacting FixYa.

I know it may sound like the shutter is moving, but you're going to have to actually look down the lens barrel to confirm it's actually moving, and not just producing a sound effect from the camera. Also keep in mind Canon's SX IS series cameras are notorious for the following problem (fantastic cameras otherwise).

The viewfinder and the picture lens are totally separate. If it looks fuzzy, and then comes out fuzzy, the capture screen inside needs cleaned. The main lens and viewfinder lenses should be cleaned too.
Get estimates before you say yes to the work. It might be cheaper to buy another camera, unless you can do the work yourself.

You mean SD400 camera doesn't show any error sign and it just doesn't have live view to shoot picture?
If yes, its problem of bad CCD imager and Canon will provide free of cost repair facility for SD400 camera.
Click Canon CCD Advisory for details.

actually when taking photos after you click the capture button you need to keep the camera still for atleast 5secs..
try this and see.you ll be able to note the difference

Try taking a picture with the camera upside down.  Sounds odd, but it's a possible check to see if the AF mirror is hanging up.

This sounds like CCD sensor is faulty and should be replaced . Camera works fine in playback mode generally with this problem but not in capture mode ( camera has gone 'blind'). Should be repaired free of charge if the camera is as old as you say.

RAW NEF images from Nikon cameras are proprietary formatted raw data directly from the cameras's sensor. If the images are improperly transferred to the computer they will not be able to be opened and will give an "Unsupported File Format" warning. Macintosh OS X has an "Image Capture" application (found in: Hard Drive/Applications/)that can be used to transfer images. If "Image Capture" is used NEF files will be corrupted and will not be able to be read. Only Nikon View, or manually dragging images from the mounted card, should be used to transfer NEF's. To disable "Image Capture": Double-click to open the hard drive and then the "Applications" folder Double-click "Image Capture" From the "Image Capture" menu choose "Preferences..." In the "When a camera is connected" pop-up choose "No Application" Close the Preferences window and Quit Image Capture After disabling Image Capture, it will not launch when the camera is connected and you can use Nikon View to properly transfer NEF images.
