When I take a picture with my canon 10d the image comes up black. I know it's not an exposure issue. I have had this camera for almost 9 years, and it's in good condition. What can I do to fix it.

What the problem looks like The problem can take any of several forms, but all involve severe color shifts and/or severe distortions of the image. The images below show two examples (courtesy of Konica Minolta) of what the problem might look like, if your camera falls prey to it. In the early stages of the problem, the camera may still capture recognizable images, but with a washed-out appearance and a strong magenta or green tint. What products may be affected? Quite a number of products may develop this problem, including digital cameras, camcorders, and even PDAs (Personal Digital Assistants) that incorporate an image sensor. The following is a list of affected models by various manufacturers that we are presently aware of. We will update this list as new information becomes available. We recommend that you check the site regularly for this and other breaking news.

SOURCE: have canon Powershot A75 3.2 Mega pixel camera .. Now it is having display issue. Once i open my camera lens come out power come but unable to see the image in lcd to shoot.. Can you assist

First try pressing the DISPLAY button. If that doesn't fix it then this sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following two links for more info:

Hopefully you resolved this already. If not, push the "DISP." button left of the MENU button. Pushing it gives you three options: black (for discreet shooting so your LCD doesn't give garner dirty looks from fellow concert goers), liveview, and liveview with info overlayed (shooting mode, ISO, etc.). Good luck!
