Canon 580EX II not working ...Wedding in a week!!

[Richard Lane]

Ok, so the Assist beam is firing. Did you go through all of your settings in the 7D menu under Flash Control.

So you pressed the pilot light when it was red (if it wasn't red then press it again when it's red), while it was off of the camera, right? I'm afraid that since the 430 works on your 7D and the test pilot flash didn't work on the 580, than maybe the flash burnt out.

When you look directly into the flash lens does it look brown or burnt?

Denise, I don't know that much about flash, but I was told to keep you talking until the experts arrive.
