Flash My camera flash won't pop up

SOURCE: Canon 450D, ERROR 99 only when flash pops up

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.

SOURCE: pop up flash won't flash it makes a clattering

i was having the same problem. tried to use the built in flash, it makes clattering sound about 3 times but it won't pop out. Then the error 05 occurred. This is what u should do:
1. open the flash manually by your hand ( carefully ).
2. Then u can see 2 tiny black screw ( u have to unscrew it ).
3. Then open the upside cover of the built in flash.
4. See a screw on the left side? Loosen it a little. Thats it. :)
How simple is that? It work for me. Sorry for my bad english. Haha
