The screen is really dark and i can't see what i am tring to take a picture of but when i take the pic it showes up but i screen is really really dark what can i do to fix the problem

The screen may become dark if Picture mode is set to Cinema or Custom. If the screen continues to remain dark after changing the picture quality mode, go to the Backlight, Picture, Brightness menu and adjust the brightness to your liking. When Power Saving is fixed to Low or High, the screen becomes dark. Some TVs have a Light Sensor so the picture will just become brighter or darker depending on the lighting in the room.
You can also try programming from a different source, like a DVD player or VCR to check whether the problem is caused by the device that sends the signal to the TV.

Show a torch light on the screen for a distance, and if you can see the picture, the backlight is not lighting up. Check for its settings on the remote, if you have that option. Check also the settings of brightness/contrast/sharpness/color. If you still have problems, please call in a qualified service technician.

First press the DISP or DISPLAY button to see if that corrects the problem. If not, 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.

This is not an answer. The S3 normally does not produce dark pictures, and I have seen this issue before. It has to do with a setting somewhere on that camera that needs to be adjusted. I wish I knew what that setting was/is as my wife's camera has recently started doing this ...

It has changed the format of the picture some how.When you open the pictures on your computer you had to have deleted the memory card.Before you put them back on the memory card pay attention to the name of the file.Copy the name your camera has called the file.The last three letters of the file is the key .

Your lens is Damage. Prevent nextime from sunlight , it damage your lens if not in use.

I have the same problem but sadly no solution.

As my camera is still under warranty I took it back to Jessops.  The camera is now with Olympus for repair.  The technician in Jessops hazarded a guess that the problem is a broken processor sitting behind the lens and as such the problem is "really bad".

Here's hoping you are still under warranty.

Full card or Firmware failure Take the old images off the card and try again with an empty card. Reformat in Camera then try. Go to Tech Support Team at Kodak
