There are two reasons for this problem.
1) if the flex ribbion cable carrying signal to shutter and appartuer motor gets damaged it does not opens the shutter. In result you get only black screen and no picture.

2) another reason is defective CCD.

both the problems can't be fixed by the user itself. You have to show it to a repair man

Try to see if you can connect the cable to a TV and see if it will do the same thing.

Example: camera - cable plug - to Input of TV.

Believe that you accidentally pressed the DISP button on the bottom back row of your camera. This manually turns the display on and off as desired to save batteries. Press the button once more to turn it back on.

I bet you can't solve this.


We have a Canon A520 and it was having all the symptoms noted. Searched for a resolution on numerous sites including the Canon Support site. While on the Canon Support site, I found an FAQ on "How to RESET the A520". Turn camera on, find and hold MENU button for 5+ seconds until "Reset settings to default?" screen appears. Arrow over to OK and press the SET button. When we did this the battery low indicator showed, replaced batteries with standard alkaline batteries. Everything functions properly, with no additional problems for the past 5 days. I guess the camera just lost its mind and had to be defaulted and rebooted, hope this helps.

Blank picture screen


Did you accidentally hit the "DISP" button on the back of your camera? It manually turns the LCD screen on and off to save batteries.

Camera will take picture, but the picture is coming out black!!!! Help Please!!!


Dear vera11:

The symptoms you're describing sound like a classic case of having a faiiled CCD image sensor.

First try pressing the display (DISP) button on the back of your camera several times to see if your image returns at any time. One of the three display modes is "off" to preserve battery life. Your problem may be as simple as inadvertently pressing this button into the off mode.

If that doesn't work, try doing a reset and then removing your batteries from the camera for a few minutes, reinstalling them and turning the camera on to test the LCD screen.

If your screen is still black, but you can clearly see pictures taken previous to the problem, and you can clearly see the menu system when you press the MENU button, then you likely have a CCD sensor problem. Contact Canon Tech Support at 1-800-828-4040 to have the camera repaired.

Hope this helps.

Sincerely,
HeavyDLB
