In shooting mode, lcd is blank, images are blank

Did you try pressing the display button several times? in both viewing mode and record mode? Cycle through all display modes, s you get used to the button, so it does not trow you off when it happens again.

1.Try initializing the Camera.To initialize the Camera, select the "Initialize" option under the "Setup 1" Menu of the Camera.

2.Even if the flash is set to always ON, the flash will still not work in the following circumstances:

* When shooting MPEG movies.
* When shooting in the Twilight or Handheld Twilight mode.
* If shooting with the Burst or Multi Burst mode.
* Shooting with Sweep Panorama.
* Shooting with the Fireworks or High Sensitivity mode.

Could be deffective CCD chip. CHeck with Canon service, they repair it for free

You might try pushing the DISP button with the unit in camera mode with the LCD open.

ssue: The LCD/Electronic Viewfinder will not display an image or the image is distorted.

1. Press display (DISP.) button to turn the display on 2. If all troubleshooting has failed, please have your PowerShot A520 serviced

well its a cheap fix, dosnt last too long. In the lower right corner of the LCD, not actually on the LCD but just on the plastic portion of the camera push very hard

Take the battery out then push some buttons - the zoom buttons or the release button - til the LCD goes blank. This sometimes resets the circuit if there is really no problem. Then reinsert the battery and try again. If the H reappears, there is a problem with your zoom. It'll have to go to a repair shop.
