Hello!

I am trying to repair a Canon 550EX flash that was given to me a couple of weeks ago. The shoe case was broken, and I superglued it, but apparently the superglue was not good enough and it broke again, disconnecting the 6 wires that connect to the shoe.

I have found the parts on the net, but I cant find anywhere where each of the 6 wires goes on the shoe. I am attaching a couple of pictures if they can help better explain my situation.

Hi,
I have 380ex "guts out".
The number of wires is the same.
If you like I can get you pic of it.

@Kledi -
I have new OEM foot assemblies for the 550 (and other Canon units) that I use when repairing these units, or doing one of my many flash and other mods (ie aux sync jack) for others who don't want to do it themselves.

If you need a photo or specs by words, let me know (probably best by e-mail directly).

looks like a good time to splice in a few feet of wire, and make it a off-shoe flash. I wouldn't trust superglue or epoxy on that break... you are lucky to get it for free though.

Thank you,

This site is about the 580, but it might be transferable to the 550. You may wish to read the comments, as there is phone number (US Canon Parts Dept) that you can use to order the parts you need.

This seems to the season for breaking flashes (on my second repaired foot)

Ironicly bringing up a old thread but is there anybody that has a picture of the wire diagram, for the hot shoe portion of the 550ex?

Hey!
The flash works fine after I have replaced the bulb. The only problem is the focusing doesn't work. The little engine tries to readjust the focus but it keeps making a rattling noise and I can't change the focus. I guess I have to readjust the position of the bulb head before putting it together. Any idea how to do this? There must be a default position for the bulb head....
Thanks!
