Question about Canon EOS 400D / Rebel XTi Digital Camera

Open Question

I have the same problem but I get this Err 99 message. It tells me to turn off the camera or re-install the batteries.It sometimes works and sometimes it doesn't Also I am in holiday in Thailand. Did the heat and humidity have anything to do with it? It never happened to me the last year when I was in Thailand and Cambodia.

SOURCE: My Canon is displaying - Err 99 what should I do?

A common cause of Err 99 on the Digital Rebels that have some age on them is shutter failure. There is a switch called CN2 in the shutter that fractures and causes either bad flash sync or shutter failure-or both. The repair is to replace the shutter. Sometimes the CN2 switch can be repaired but we find at our shop it's better to replace the shutter with a new one. That way, with a new shutter, you will get years more of good service from the camera.

There are other causes for Err 99. Check the electrical contacts on the rear mount of the lens and the coresponding contacts in the lower portion of the mirror box in the camera body. Make sure they are clean and not distorted or bent.

There are more but these two are, by far, the most common.

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.

SOURCE: Error 99 message keeps popping up

Hi

I just read that the error 99 problem is a shutter failure and the shutter will have to be fixed. The cost is about $180.

see http://www.mcvr.com/canon_digital_rebel.htm?gclid=CJqG4cvc05oCFRMhnAodCHUA3Q#shutter


ERR99 (error 99) is an indication that there is a communication problem in the camera. It is most often an indication that the shutter needs to be replaced, but it can be the result of other problems. All digital cameras occasionally need to have the shutters replaced. In the days of film cameras, it was rare to wear out a shutter because the cost of film and developing limited the number of times the shutter was cycled. With all those ones and zeros being considered "free" in digital cameras, it is not uncommon to take several hundred or more photos in a day. Even with a live-expectancy of 50.000 to 100,000 cycles, the shutters in digital cameras do reach the end of their life and need to be replaced.


Shutter replacement (usually associated with error code "99"):

  • Replacing the shutter on the Digital Rebel series requires more disassembly than most other repairs.
  • The estimate for shutter replacement is $180 on all EOS Digital Rebel models (depending upon the overall condition of the camera).
  • ERR99 error codes are related to shutter or mirror operation and are usually associated with a defective shutter. Cameras that have had heavy use may have shutters that have reached life expectancy and need to be replaced.

If you need to have it serviced go to the caon webpage and click on support. Try calling one of the support numbers or if available the live web help. They will then tell you how to get the camera to them and what to expect. I've found them to be real good to deal with which is always nice when you have a problem.
