Motor is dead ¶

No light from flash ¶

Fuse is burnt out ¶ 

The indicator LED will illuminate, signalling that the camera is preparing to flash; however, no flash will occur. If this is the case, replace the flash.

None of the above ¶

If none of the step above solve the problem, the resulting effect is due to a malfunction of the main board. The main board is very complex and can result in many different problems. If you have replaced other components such as the battery, LCD screen, or lens mechanism, it is likely that the main board is the resulting problem and needs to be replaced.

Lens will not extend when camera is turned on; screen first shows Cannon logo while green light flashes, then a beeping sound, then screen indicates: "lens error, restart camera". After this, the camera shuts off.
