My 1d3 seems to have developed a fault during the last 24hrs :(. was grand last night when i took a few shots, left it back in the bag on the back seat and now ive gone to get it and clean the sensor and its not working.

its coming up with err99 shooting is not possible, etc. seems that the mirror isnt doing anything, either taking a shot, live view or sensor cleaning mode.

anyone know a quick fix? warrenty is up so dont mind opening it if i have to. Got a wedding tomorrow im leaving at 8 am for so dont know if ill make it to a shop to get a loaner. Got my 1d2s but need the mk3 for teatherd shooting during the evening.

:help::thumbs:
 
a quick google came up with this.

"I have seen many postings on this and just wanted to share some troubleshooting that I went through with Canon. I received frequent Err999 messages last month. I would hear the shuttler "slap" and then the err would show up. Nothing would be saved and I would have to power off then on.

I had to send mine in and the shutter mech was replaced.

Here is what Canon said to try:


Thank you for contacting Canon product support. I'm sorry to hear that
your EOS 10D is displaying an "ERR 99" message.

To isolate the cause of the issue, we suggest that you 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 a fully charged battery, and turn on the camera.

Does the "ERR 99" message appear? If it does, then the camera should
be serviced. If it does not, then please proceed to the next set of
steps:

1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.

Does the "ERR 99" message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.

If the message does not appear, please complete the following steps:

1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.

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 should be serviced.

For factory service, forward your digital camera (remove the CF card
and battery) properly packaged and insured, with a letter describing the
difficulties. Be sure to include your name, address, telephone number,
and proof of warranty (if applicable). Send to the Canon Factory
Service Center at the following address:

Canon Factory Service Center
100 Jamesburg Road
Jamesburg, NJ 08831
Tel.# (732)521-7007

or

Canon Factory Service Center
15955 Alton Parkway
Irvine, CA 92618
Tel.# (949) 753-4200

Your equipment will be examined and you will be advised of the
findings.
The length of time for the repair will be dependent upon the nature of
the repair and availability of parts if needed. If the repair entails
something that is not covered in warranty you will be sent a written
estimate to the address that you have provided.

Thank you for choosing Canon.

Sincerely,

xxxx
Product Support Representative"

hope this helps.
 
Cheers for the reply.

Managed to get it going again, no idea what caused it. Took both batteries out and replaced them and it still wouldnt work.

Had another google then switched it on again before bed at 2am and it worked fine! Didnt miss beat throughout the whole day but ill be sending it off to get sorted later today, cant it have it happen again.
 
recommend that you send the lens that was on at the time of for a service as well. As that may have been the problum
 
Not sure how useful sending it away will be. Without the fault actually occurring, there is very little an engineer can do to fault find, unless it's a known problem with that camera and a known fix is in place.
 
Part of the service will be to clean the contact points which is what might be causeing the problum. Also to judge the shutter count and either service it or recommend replacment
 
No lens was not at fault, lens off, the mirror wouldnt flip, no live view or sensor cleaning mode, think its something to do with the mirror not engaging properly so it tires to actuate the mirror but it does not register so gives the err99 before opening the shutter curtain.

Will have to see if the camera logs past faults.

Mirror lift is part of the shutter, Sounds like the shutter might be on the way out
 
And this is why wedding photographers have all their gear in duplicate I guess!
