Question about Canon PowerShot A75 Digital Camera
Posted by Anonymous on
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:

camera uses SD memory cards. On one edge is a slider switch: towards
the electrical contacts is the unlocked position and away from them is
Unfortunately, the switch is easy to move accidentally and it's also easy for it to appear to be unlocked when it isn't. Like any mechanical component it's also possible for the switch to fail.
If the switch is in the locked position then slide it fully to the unlocked position; if it's already in the unlocked position, slide it fully to the locked position and then fully back again. There should be a soft click at each end of the switch travel, if not then the switch is definitely faulty or obstructed.
If that fails, then try looking closely at the switch in both positions to ensure that there is no debris obstructing its movement, if not then check the electrical contacts to ensure that they're completely clean and grease-free. Don't touch the contacts with your bare skin, but if the contacts need cleaning then a cotton bud (Q-tip) moistened with a little alcohol or methylated spirits can be used to clean them.
If you still have no fix, then try a different SD card as yours may have an irreparable faulty switch. If the card does prove to be faulty then on most major brands you may be able to return them to the manufacturer for exchange: I've found that they will often do this on a goodwill basis even if the card is out of warranty.
If all options regarding the memory card are unsuccessful, then you have a faulty camera and further remedies require either a professional repair or replacement of the camera.
I hope that my answer has been of use and has given you additional options to fix your problem. Please take a moment to rate my reply.
