Canon 40D - Err 05

SOURCE: built-in flash auto pop-up problem

Does the 'pop up' pop up? If it does and still says obstructed- closes it and pop it again If it still persists Canon customer support will advise the next move. If a repair price seems high you could perhaps get a separate flash if the camera accepts them.

SOURCE: Error Code 05

Just because you've turned the camera off/on, doesn't mean it's been reset. This is a fairly easy procedure which involves either going into your setup menu and choosing "reset," holding down the menu key for 5 seconds, or, removing the batteries for a few minutes. It may be that the firmware loading got corrupted and the camera just needs to be "rebooted," which is something that turning it on/off won't accomplish. But after which, you should have the camera reset to factory default settings.

Another tip is to go to Canon's website and look for firmware updates. Download and install them.


Err 05 is when the internal flash is obstructed or the camera doesn't get an reply that the flash open sucessfuly. That should be covered in warranty if its an faulty "pop up flash." Call Canon at 1-800-OK-Canon or Email them at: https://consumer.usa.canon.com/ir/controller?act=SupportMailerAct&fcategoryid=215&modelid=9430

Talk to them and they will give you a more in depth stuff.

Dear joefrisco:

An ERR 05 message indicates that the camera's flash pop up mechanism has encountered a problem due to either an obstruction (such as your hand or something blocking it), a jam (impact damage), or an electrical failure.

Try the following steps, in order, to try and resolve the issue. If nothing works, the camera will have to be sent in for service (call Canon Tech Support @ 1-800-828-4040):

1. Turn the camera off. Ensure that nothing is blocking the pop
up flash. Turn your mode dial to one of the Creative Zone
modes (P, AV, TV. or M). Now turn your camera back on
and attempt to take a flash shot. You will need to manually
press the flash button to do so.

2. Turn your camera on and perform a hard reset by pressing the
MENU button, tabbing over to the Set Up 2 menu tab and
selecting the option "Clear Camera Settings / Clear All
Camera Settings" options, and then removing the camera
batteries, date/time battery, and memory card for a period
of approximately 2 minutes. Then reinstall all items, turn
your camera on, reset the date and time and perform step
number 1 above.

Hope this helps.

Sincerely,
HeavyDLB

Can you pull it up manually, Be careful when doing this but try opening it manually, it is possible that the catch for the flash is just stuck temporarily.

Err 99 usually means your lens contacts are dirty either on the lens itself or on the camera.

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.
