There are two versions of this problem: 1. The flash does
not pop-up. 2. The flash does pop-up.
Here’s the fix to the err05 msg when the flash does pop-up. This will work on the XTi and perhaps on similar Canon cameras:
The pop-up flash has two legs. Look at the pivot point of the right leg
(”right” when looking into the lens). Just in front of the pivot is a
very small spring-load pin on the “roof” of the camera body.
This pin is the sensor that tells the camera the state of the flash.
The pin is pushed down when the pop-up flash is closed and is suppose
to quickly spring up when the flash is opened. Problem is, the pin
sometimes gets dirty and drags. When it is slow to spring up … you get
the err05 message.
Fix: Take a small jeweler’s screwdriver and dip the tip in isopropyl
alcohol. (Don’t use any other solvent unless it’s designed for cleaning
electronic
parts!) Then touch the screwdriver tip to the pin. Do this several
times until the pin area is nicely wet. Then push the pin up and down
until it is able to spring up quickly.
Enjoy.
