It sounds like you have some bent pins in the card slot. Take it to a reputable camera repair and they can look and tell you for sure.

Hi there,

Well first of all you can try a full reset, Pull both batteries out -the normal one, and the date/time one. If your camera is older (>2 yrs), it may be time to replace that battery..... anyway Put a new one in, and then put in the freshly-charged main battery, that might clear the error. If further you have the same problem then something is causing the flash to stick. Press the button and pull gently on the flash. Post comments for more help or information needed.....

Good Luck!!

Thanks for using FixYa!!

Joe, this happened to me, just tonight... I got a new CF card and stuck it in, turned it on and one CF card flash. Completely dead from there. I found one of the CF card pins bent over, shorted out the socket and blew the mainboard fuse. I took the camera apart, found the fuse (labelled K) about under the set button area) I bridged the fuse with a bit of solder, straightened out the pin in the socket, put it all back together and it's working fine. The fuse is under the right side shield cover, it's labelled with a letter K. There is another fuse on the power inlet board (below the shutter button) and it's labelled 'P'...

To isolate the cause of the issue, do the following: -
1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert only a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, the camera may be faulty and requires a service. If it does not, then: -
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.

Does the “ERR 99" message appear? If so, then the CF card is faulty. Try a different card. If the message does not appear: -
1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.

If the “ERR 99" message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99" with a different Canon lens attached, then the camera is faulty and should be serviced.
