I have two 5400HS flashes for my 7D. I can get neither to work in wireless mode. I have them synced. I have tried using a single flash remotely with the on-camera flash. I tried attaching one flash as a controller. In short I've tried everything. I can press the AE button to test and everything lights up OK but the flash simply won't fire when I take the shot. I have to believe that this is operator error but I cannot figure out what to do.

Re: Cannot get wireless flash mode to work on my 7D
It is not operator error. I had a similar experience and spent days pulling my hair out trying to figure out the problem.
Unfortunately, the 5400HS is NOT compatible with the 7D. Only to 3600HS(D) and 5600HS(D) are.
The problem stems from the fact that the digital cameras cannot to TTL (real-time) flash metering and have to rely on pre-flash instead.
Because of this, Minolta updated the control protocol to include a signal to tell the flash to pre-flash. Unfortunately, only the two newer flashes recognise and respond to this new signal.
I spent weeks trying various things to get around this, but with no joy. Sorry to be the bearer of bad news, but your 5400HS just will not work properly with the 7D either wirelessly or when attached to the camera.

The err code 05 says the same, Flash could not pop up. The manual says, switch off the camera and switch on again.it could be this does not change anything. Just a little more chance, when you switch off the camera and remove the battery. And while it is out, just charge the battery. When you replace the battery and the error reoccurs best guess you have to visit the Canon service centre.
Make sure there is no mechanical obstruction, that keeps the flash from popping up.
First, you have to be in one of the PSAM modes; in the other modes the camera decides whether it needs the flash and in daylight it will decide there's enough light without it. So, after turning the model dial to one of the PSAM positions, press the flash button on the front of the camera to pop up the flash. In these modes the camera will fire the flash if it's popped up, and not if it's down.
To change the flash mode, hold down the flash button (after it's popped up) and turn the command dial. Depending on the chosen exposure mode, your choices may include Fill flash, Red-eye reduction, Rear-curtain sync, Slow sync, Rear-curtain plus red-eye reduction, and Rear-curtain plus slow sync. Refer to the "Flash Mode" section of the manual for full details.
It's probably because you have enabled the slow sync flash mode.
To switch to the normal flash mode (auto flash) press your left directional key until the flash mode indicator near the top left of the screen (an icon with a "lightning" symbol) changes to an icon with a letter A next to the lightning symbol.
The slow sync flash mode is different from the normal flash mode; in this mode, the camera exposure duration can be a few seconds and the flash actuates at the beginning of the exposure. Although this is useful for certain photography techniques, you have to enable normal flash mode to take pictures in the normal way without blur.
you have to take it out of auto mode to have any control over flash, try putting it in P mode then press the flash button which is next to the flash. if this doesn't work, take it back to where you got it from to take a closer look.
If you shoot in the Basic Modes (any of the modes with icons like Portrait, Landscape, Sport, etc), the flash will pop up automatically if there isn't enough ambient light even after pushing it down to close it. To shoot without auto flash, use one of the Creative Modes like P, Av, Tv, M etc. If your problem is that the flash springs back up again when you try to push it down, the catch may be faulty. You may want to consider taking the camera to an authorised Canon repairer.
If you are in Manual Mode and you set your shutter speed too higher (ie above 250th sec) the shutter blind passes over the sensor when the flash goes off causing a dark section in the photo. Lower the shutter speed to get a better sync. Some camera's default sync speed is 1/60th of a second and sometimes user adjustable.
Remember the longer the shutter speed, the more light will register in the photo. Also boosting the ISO will help extend the flashes range and also record more ambient light for a more pleasing and balanced photo.
Sorta, it will flash, but only in manual mode, all the benefits of having a gee whizbang electronic flash are lost jumping from the film to digital cameras, the film cameras metered the flash off the film plain, and quenched it when enough light had hit the film, they couldn't apparently figure out how to do the same thing for the digital sensor, so the flashes behave differently, you need a D flash like the 3600 or 5600 to get automatic flash with the KM 5d, 7d, or sony A100 cameras... sorry... if it's any consolation, I'm in the same boat. :(
