Hi - I have a Rebel

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
