Simply right click on the track itself and select send to/DVD-RW or CR-RW depending on the type Compact disc drive you have. Then you will see a notification, "you files to be written to CD." Simply click on it or go to your Compact disc drive on My Computer and click “write these files to CD.” Then follow the screen instructions. IT is that simple. All you need to do is press and release the display button until the screen displays. Usually Canon Powershot cameras have 3 display modes:- colour, black & white, blank. Your camera is set to blank that is why you cannot see any image/screen displays no image. Just press and release the display button until the screen displays. That should do it.

A stuck shutter is a 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.
