These instructions are for the 550ex and I imagine that the bodies of the flash units are the same.

As with any project, make sure to get a good workspace with plenty of light where you won't drop any screws and lose them...

1) There are 4 screws on the bottom of the flash unit that you'll want to unscrew first. Carefully tilt back the bottom section away from the red filter which covers the "eye".

2) There is a set of wires going to a white harness in the piece you just tilted off which you can carefully disconnect with a small flathead screwdriver working it on either side.

3) The same type of harness attaches another set of wires but this one is just inside the body of the flash in the cavity you just opened up. This one is a bit wider and you should undo that harness in the same, careful manner.

4) Next, you have to remove the master/slave switch which is attached with two small screws that you'll need to carefully undo. The actual switch is attached to the tiny board you are unscrewing. There is a plate covering that switch that is the piece you actually push when you want to switch it. That piece will come out when you take the actual switch out so remember which direction it went.

5) Now you should have exposed four small screws as you look straight down into the piece you're working with. These screws hold on the shoe you're replacing. With some decent force against the screws, carefully unscrew them. These don't come out very easily so you want to make sure you have the right sized screwdriver that fits and that you're applying some downward force. MAKE SURE you don't strip the head on these screws.

6) Turn the whole piece so that the shoe is facing upwards. Now you can carefully pull off the shoe. Make sure to not lose the loose spring that is under this thing. You'll see that there are 5 prongs sticking up, a horizontal metal piece, and a small rod looking piece with a spring that fits over it. Take note of how these all go so you can put the new one on with those pieces in the right places.

7) Put the new piece on and screw everything back in the reverse order. Voila! You just saved yourself a bunch of money and hassle. Thanks for the tip on where to get that piece, by the way, I had been looking around for it.

I have been using my Canon 580ex ii with my Canon 5d mark ii. It will not fire at all now. I also tried my old 420 ex speedlite and it will not fire either. But, they both work on my Canon 40d.


You can actually set the external flash not to fire in the menu settings of your camera. Check there or try mounting the flash on your camera, turn both on and reset your camera to factory default settings through your camera menu settings.

I have a canon 60d and i mounted on the 580ex speedlite and it turns on but it wont fire. help?


Hello,
Usually if my flash isn't firing I check to see if the flash is mounted into the hotshoe properly. I take it off the camera, put it back on and tighten it down then test it.
If that doesn't work then check the display of the flash and see what mode you are on or if the display is flashing. If it is flashing then the wide angle adapter may be covering the flash which you will need to take off and put back inside the flash. It's that white plastic tab that slides in and out of the flash head.
Hopefully that will fix it.

580EX speedlite not firing


Does the pilot lamp light up? If so can you fire it manually by pressing on it? If the batteries are low it may simply just be taking a while to charge, the camera will not wait for it to be ready to fire and it may seem to be not working. If your flash can be fired manually however, there may be a problem with the cameras shutter or the hotshoe. You can do a basic check by pressing the star button at the rear of the camera, you should get a pre-flash. If not, there is a problem with the cameras hotshoe which you will need addressed by a service centre. If you get a preflash you can next check the cameras shutter by setting the second curtain to sync with the flash. This can be done via the cameras "Custom Function" menu, c-Fn 15. Set the camera to TV mode and chose a 1 second exposure. Take a shot with the flash attached, if the shutter is working correctly, the flash should fire a pre-flash and then a main flash. If it doesnt, the switch inside the shutter is broken and the shutter needs to be replaced. This is a pretty labour intensive repair and you may consider an upgrade as more economical.
