I can view pictures that were taken on my camera but when I go to take pictures the screen is black

I can only offer this: (sorry if it does not help)
When the micro USB Cable is plugged into the camera you MAY be able to take photos. The camera MAY work normally EXCEPT for the MONITOR or Screen. The screen is TURNED off when you plug in the cord.

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. http://camerarepair.blogspot.com/2009/05/simple-fix-for-stuck-shutter.html

No this camera does not have any internal memory. All images should be written to the memory card if the memory card is inserted properly. If the memory card is not inserted correctly the camera screen will show a message of No card. Do you see that message?

Please check the image size (pixels x pixels) setting or the resolution (MP). Seems like the camera is shooting in low resolution. Have you used this memory card on a mobile phone or another camera? Format the memory card and try again.

Hello, I went and researched a few points in the manual and hope this helps to some extent. If this doesn't help, try resetting your camera by removing the batteries for 30 seconds, then reinstalling them and turning on the camera again.

Its common problem in canon cameras and I have solution. please let me know if you didn't find in chat.

Once you took pictures without a memory card, all pictures taken will automatically be saved on the INTERNAL MEMORY of the camera.
When taking pictures with a memory card, all pictures are just saved on the memory card itself.
If you are seeing 100-757 on the LCD screen. It means that there are already 757 pictures taken from the first time you've used the camera.
It is possible that some of the pictures are in the internal memory and some are in the memory card.

STEPS to DOUBLE CHECK:
1) Remove memory card out of the camera
- Turn on camera
- View pictures on the internal memory
by just pressing on the PLAY mode button
(lowest of the 3 little buttons)
- Pictures seen are just the ones saved on the internal memory

2) Return memory card back in the camera
- Turn on camera
- View pictures on the internal memory
by just pressing on the PLAY mode button (
lowest of the 3 little buttons)
- Pictures seen are just the ones saved on the memory card itself

*** If you want to transfer pictures on the internal memory of the camera to your MEMORY CARD, you just have to follow the steps below:
- Make sure there is a memory card inside the camera
- Turn on camera
- Press on PLAY mode button to view pictures
- Press MENU/OK button
- Keep scrolling to the right until you see COPY TO CARD
- Select YES using the arrow keys
- Press MENU/OK to confirm
* When you've done these steps, all pictures from the INTERNAL MEMORY of the camera will be copied to your MEMORY CARD but it depends on the space left on your memory card

** If still, you could not view the pictures, it's possible that the pictures are really gone when you have transferred the previous pictures to your computer.

** Once you have transferred pictures to your PC, and you have deleted those on your camera, the FILE NAME of the pictures will not start from 100-001 again unless you have reset the file name on the settings of your camera.

In example, i already have 256 pictures on my camera so the filename reads 100-256 for the last picture taken. And then i decided to transfer those 256 pictures to my PC and i deleted those immediately after being transferred. So, as i took another picture, FILENAME will start with 100-257 if i have not reset
the FILE NAME settings to 100-001.

Hope i've helped you enough.

My viewing screen is black. I had successfully taken a picture, viewed it, and turned the camera off. When I turned it back on about 30 seconds later, the viewing sceen was black. I can 'take' a picure, but it comes out black. Help!

When the picture does not display - do you see the normal text and icons that you would expect to see? Or, is the screen completely blank?
