Having problems with your Canon PowerShot A640 Digital Camera ?

Camera works but the screen went black A640 except for video and color swap. Did I press a button? I was shooting in cold weather.


Answers :

Think that you might have accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the LCD display on and off to save batteries. You would then use the optical viewfinder in its place. To turn the screen back on, just press the DISP button one more time.

\015\012But if you've already tried this, have you also tried downloading any of your photos taken with the black screen to your computer? Are the photos also black? If so, you might instead be experieincing a stuck shutter (possibly due to the cold weather).
\015\012
\015\012A 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).
\015\012
\015\012To 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.

Coolpix L5 was functioning perfectly until today. Now it boots normally, focuses normally when the shutter button is partially pressed, but does nothing when the button is pushed all the way down. It will not shoot stills or video or even self-time a still shot. It behaves exactly as if the actual shutter release button is broken and doesn't make contact at the full pressed position. New batteries, memory card, resetting default menu settings--none of these help. It's running firmware 1.0.

My Sony Cyber-shot DSC-S600 stopped working. I press the power button and nothing happens. I tried changing batteries, but it shows no sign of life. It was left in the trunk of my car overnight, inside a luggage bag. The temperature was close to freezing, so maybe the cold weather had something to do with the problem. I left it in my closet for about a week, and when I tried to use it, the power would not turn on. Thanks for your time.
