    I am having the same problem with the flash not popping up, and getting error code 05. Your 'fix' was not published. Would you mind sharing a step by step on how/what to do?


  • huntersjames Nov 08, 2007

    I have the same problem -- in flash mode, I get the 05 error code; it works when not in flash mode, just not when in flash -- is the bulb burned out? the camera shop told me that they aren't worth fixing, can you believe it????

    I have the Rebel Xt and the same problem. My camera will flash if I open the flash by hand. The flash pop-up button does nothing. I don't feel anything when I press the button and the latch never moves. Is there a motor or something that releases the latch? Should I hear a noise when I press that button? Can this be fixed at home or should I take it to a shop?

I had the same err 05 problem on my canon 350d. But there was no need to remove or open anything! If you have the camera in front of you looking at the lens, you can see a tiny black switch hidden under the flash. On the right side where the flash is attached to the body you can find a fine black piece of plastic sticking out of the camera body (smaller than 2mm. This switch can easily get stuck with some dust (or a grain of sand in my case)
Carefully clean it (with an ear stick) so it can go up down again as the flash goes open or is closed. (It somehow serves as a mechanical sensor)
This solved my error 05. Remember that this is just a general Flash error indication and there could be another problem triggering the warning.

I have been working with this very problem on my father's camera. I tracked the problem to a liquid of some sort had splashed the camera at some point and had gotten into the small switch that is near the base of the hinge that tells the camera that the mast is extended. The switch could also get gummed up with dust or other things as well. It does require a full dismantling of the camera to work around on the inside of the prism. The take apart is not an easy task to complete and there are quite a few screws that need to be put back in the same place. The camera now properly extends the mass and registers it without the annoying "err 05" warning. Not suggesting this repair to anyone that isn't extremely familiar with dealing with delicate cabling that are usual found inside devices such as these. With all the suggestions here the usual disclaimer if you break it more when working on it you have no one to blame but yourself.

The problem is not in the hot shoe area but in the locking unlocking mechanism for the pop up flash. Situated on the inside of the top cover which has to come off completely so that you can adjust the position of the unlocking mechanism ( or replace it , but not the entire top cover ). Camera not releasing the pop up flash and goes into error mode.

I've been struggling with this one for days now. It took a combination of resetting the camera (by removing and re-installing the battery), then applying gentle but steady pressure on the left side of the flash toward the right while keeping the manual flash button pressed.

How does the release switch feel? If you don't feel the two separate 'pops' when you depress it then it probably needs to be replaced. Try pushing it all around - from the front, back, both sides, etc. and see if you can get the camera to release.

Set the menu so you can fire the camera without a card inserted and see if it will then fire. Also remove the lens and set the camera to 'M' and see if it will fire.

Check the CF pins for bent pins.

Canon EOS Rebel XT Error 05 or BUSY

The Error 05 means the build in flash cannot be raised.
In the moment it should pop up, something was blocking the free movement. Could be caused by the way you were holding the camera. Could be happening, while you were pressing the flash button, or when you are in the basic zone shooting mode, such as portrait, which needs the use of the flash.
Switch the camera off an then on again. Move an eventually cause of the blocking and press the shutter realise button again.

Err 05 on Canon 7D

The error code is used to tell you the flash could not be raised. Check if anything is blocking the free movement of the pop up flash. First reaction should be, switch the camera off and then on again. Better though, after you switched off the computer remove the battery and charge it first, Then again try everything as before.
The manual says is the error persists, wroth down the error number and contact your nearest Canon Service Centre.

Canon EOS Rebel Error message E05

Go the the Canon support website and enter your camera model. If there is something you can do, it's there.
The E05 error says the lens is jammed or not working correctly. My guess is you need to take it to Canon.
This happens if sand gets in the lens or the camera is dropped.

Canon EOS Digital Rebel XT will not turn on.

It could be a number of things. The first thing you shouild do is remove the back cover and check for loose screws. If you don't find any, the problem may be a damaged battery door switch, a damaged memory card slot door switch, or worse- it may be a defective power board.

I have a Canon Rebel XT and I am getting an error 05 message when taking pics indoors.

This sounds like the flash obstruction error - a fairly common issue with the Rebel XT. For some reason, the built in flash tends to get sticky if it's not used often. From what i've read, the best work around for this is to "exercise" the flash.

Basically what you do is when you press the flash button, either help it with your finger or thumbnail, close it again, re press the button, and keep doing it a few times. You'll find the flash gets less sticky.

You might also want to see if it gets caught on the Canaon nameplate as it tries to pop up. All it takes a smidge of friction to throw this error

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.
