There is no image on the screen or the viewfinder in camera mode

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.

Your viewfinder, focussing screen, and mirror are out of alignment. You need a service technician to fix the problem.

I think there is a small button on the back of the camera near the bottom that turns the viewfinder off and on I think. It should be in the manual.
It might have gotten bumped while in the bag.

Hi,

Apparently the vendor-supplied CCD image sensor used in this Canon digital camera may cause the following malfunction: When the product is used in recording or playback mode, the LCD screen and/or electronic viewfinder may exhibit either a distorted image or no image at all.

To determine if the CCD (image sensor) is working properly, follow these steps:

1. Insert a memory card with known good images on it into the camera.

2. Power the camera on to the Playback mode.

3. Press the DISPLAY (DISP) button to enable the LCD panel, and observe
the LCD.

a. If the images are displayed properly, please proceed to step
four.

b. If the images are not displayed, or a "NO IMAGES" message
appears, please ensure that the memory card contains known good images.

c. If the card contains known good images, and the issue persists
with a second memory card, the camera will require service.

4. Switch the camera to the Camera mode. You may use any shooting mode
(i.e. Auto, Manual).

5. Press the DISPLAY (DISP) button to enable the LCD panel.

6. Point the camera at a well-lit scene and observe the LCD and/or
viewfinder. If the scene the camera is pointed at appears on the LCD
and/or viewfinder, the CCD is operating properly. If the LCD and/or
viewfinder remain black, the camera requires service.

Effective immediately, and regardless of warranty status, Canon will
repair, free of charge, products exhibiting the above-mentioned
malfunction if the malfunction is caused by the CCD image sensor. Canon will also cover the cost of shipping and handling in connection with this repair.



Regards.

Cycled through display options, still couldn't get viewfinder image. Checked images already on card, and they showed OK, so screen operating properly. Went back to viewfinder mode, got lots of horizontal lines across screen. Realised I could do no more, so took camera to shop it was bought from, who checked it and said it had an electronic problem that needed professional repair facility, so camera has gone for an estimate of repair cost.

Hello grnca,
CCD Imager ( an electronic part) at the end of Lens Assy got defective thats why you can't see any result in camera mode.
Please contact nearset Sony repair shop for replacement of CCD Imager IC.

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

That is normal. Didital SLRs are different in this respect from digital compacts .

the ony way is to get the CCD replaced with a new one. Contact NIKON for free replacement as this comes under manufacturing defect.

If you turn on the back LCD, the electronic viewfinder will remain on while in a shooting mode. There is no setting on the camera to use only the back LCD monitor while shooting. If you playback images in the Play mode, only the LCD monitor will turn on. However, if you press the Monitor button while in the Play mode, than the back LCD monitor will turn off. The image will display only in the viewfinder LCD.
