To autofocus the sensor needs a fair amount of contrast (light and dark eges) to operate. If you're trying to take a photo in a dim room of a dark colored subject for instance the focus won't lock and the camera won't take the picture. Try switching your lens to manual focus and shoot that way.

In addition to resetting all the camera settings you should also choose the "clear all custom functions" option that is also available from the same menu. Once that's done. Put the camera in Full Auto mode and see if the issue is resolved.

I have a Canon EOS 40D camera. We are having problems with using an external flash. The pictures always come out extremely dark with the external flash. The flash seems to work fine, it flashes...

I don't know if this will help and this post is two months old. The camera store may be right that the synchronization is the issue which tends me to point a finger at the external flash. There are at least three different flash units that will flash when the picture is made but only one type will sync with the camera. A digital flash unit is different from a film flash so a Canon EX type is required to sync with Canon TTL or TTL II digital cameras. An EZ will flash but it's off a bit, so I can only assume that your Promaster and Canon flash units are for film cameras. Okay and another thing that could be throwing things off a bit is the camera may have been programed in Custom Functions to use "Second Curtain" or "Rear Curtain". Just seams to me if the built in flash works then it's the external units at fault.

Internal Flash not working-Canon Eos 40D

I've had this happen to me too and I've been researching about it. Aparantly it happens because the camera still think the external flash is attached. If you go into the menu and under flash control, try ot enter the settings for built in flash. If this is the problem it will tell you here that the external flash is still attached. From what I have read to far, I'm not sure how to fix it. I would reccomend taking it in somehwere. I dont htink its a hard problem to fix.

Basic info needed Where do the Batteries Go? etc What do the settings all mean?

Your manual is here

ISO settings are basically the way the camera responds to light. The higher the ISO, the more the camera will take low light images. The trade off though in higher ISO is that you get grain.

You can use any infra red or Bluetooth flash unit, but make sire you get on that lists your particular model. That way they actually work from the amount of light that hits the CMOS sensor inside the camera itself.

Flash units. Take a Look at Metz, they are the brand leader.

Built in flash problem

most likely you have set the camera to the auto mode and you are shooting in a place with plenty of light.
your camera has a sensor which activates the flash when needed.
you can set the camera to the manual mode so that you can chose the flash to work even in the day.

Err 05

In my case, I borrowed a camera and when I got it back, err 05 appears. I've located a bit of old orange juice which sticked one of the sensors - you can see the sensors when flash is popped out.

Canon Digital Rebel XT Bulit-In Flash Strobes in Low Light

use more light:)
its very normal that it does that. it dosent get enough light so it cant focus. the only way it can autofocus is that it stobes the flash to adjust the focus automaticly. use an external flash like 580EX and u will get an focus asisten thru a red grid throne by the flash unit.
