Hi Chrissy, I had observed the same problem - after an external flash had been removed from the camera, internal flash didn't pop up. Tried to look at the Google and finally found the solution. It helped me and could help you as well:
The usual reason is that the camera thinks that there's an external flash mounted on the hot shoe. Check the external flash detect switch. It's located under the right side of the shoe (there is a metalic piece which is kind of "elastic". Just try to push it and release several times, may be put the screwdriver softly under it and out... It helped me. Here is the picture of location of the detector.

My new canon rebel T2i/EOS 550D Flash is not opening when i press shoot, it tries and tries and tries and show error 5.


A 5 error is the camera thinks the flash is not raising. Look near the hinge for a small button and see if it is up or down. This lets the camera know is the flash is up or down and if the button is stuck down you will hear the motor fire a few times and it will then error.
Unfortunately, this is one of the problems that starts to appear on cameras with pop-up flashes. You can hit the button and pull it up at the same time. Only other option is to send it to Canon to get it repaired.
or, Get an Speedlite like the 430EXII or 580EXII. The flash unit may make your camera bigger, but the results will be much better once you learn flash techniques.

Canon Xsi will not read external flash.


The XSi is not weather sealed like the 580ex II and is suseptable to liquid damage. Most cameras will take a few sprinkles and won't have a problem, but if the liquid got into the main body it might have issues. The top of the camera around the hotshoe is particularly sensitive.

I would doubt it could be self repaired. Take it to a liscensed repairer to have it looked at.

Canon speedlite 430 EZ does not match with canon 400 D digital camera how to use the same flash with 400 D.


You can't. The metering systems are incompatable. You must use the EX range with the 400D, such as 430EX or 580EX (versions I or II)

I made the mistake of putting ahotshoe protector from my old camera on the new EOS 400D. It stopped the flash from popping up. I took it off and things now work.

Xti and Speedlite 200E


The only way to solve the problem I see is to turn the flash into non-TTL one. It can be easy done by opening four screws at the connector side of the flash, unsoldering or cutting the BROWN line and closing the connector back. The AF assist led will work.

That I did on my 200E with Canon 400D camera and all works file.
Enjoy!

Flash doesn't work


I found the answer and fixed my flash. Look on http://photo.net/bboard/q-and-a-fetch-msg?msg_id=00ODWf

This will describe how, if you have been using a speedlite alot, than the little tab under the shutter release side of the hot shoe can get bent down thus constantly pressing down (toward the bottom of the camera) the small button which deactivates the pop-up1.gif flash even when the speedlite is not attached. Just bend the tab up a little with a jewler's screwdriver, turn the camera off and on and voila!! Fixed!!! Dan describes pushing the tab down, but on the xti, the tab needs to be bent up to release the flash deactivation switch and fix the problem. Thanks to Dan D on photonet for saving me a service call.
