is your lens cover open for sure?

The most likely cause for this is a damaged or defective flexible ribbon cable that connects the vewfinder LCD to the camera body and can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired by a qualified service technician.

My name is Rick and I'm a professional repair technician with over 20 years in the business and have repaired many of these. I'm semi retired and work from home with little overhead so I can keep repair costs low. If you decide to have the camera repaired, please click HERE for a directory listing that suits your needs.

Click the "disp" button. The display of the camera has been turned off in the LCD screen but you can still use the viewfinder, this functionality is just for those who prefer to use the viewfinder instead of the LCD screen.

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.

LCD = Lousy Camera Device? Get used to using the optical viewfinder. The LCD is great for reviewing images after you've taken them, but it leaves a lot to be desired as a viewfinder. Keeping your camera steady is no small feat at the best of times, but being forced to hold the camera away from your body to view an image through the LCD adds a new level of instability to the picture-taking process.

When the product is used in camera mode, the liquid crystal display (LCD) panel and/or electronic viewfinder displays either a distorted image or no image at all.

Sony Corporation has determined that this condition occurs very rarely, but may be accelerated if an affected product is exposed to high temperature and/or high humidity environments.

In an effort to ensure customer satisfaction, Sony of Canada Ltd. has elected to offer, effective October 3, 2005, free out-of-warranty repair to owners of affected Sony digital camera, camcorder and PDA products that exhibit the aforementioned condition caused by the image sensor device. See below for a list of affected models:

Since the viewfinder sees the subject different than the picture taking lens, we recommend using the LCD monitor screen for taking macro pictures. The image previewed on the LCD monitor will be the exact image that is taken.
