Hi,

I'm having trouble getting my sigma flash to work on my camera. I used it once for a party about a year ago and then when I tried it a month later it would not work and hasn't since. Has anyone else had this problem? I have tried all the camera settings I can think of and the flash will flash if I press the test button.

I am taking it to a repairer this week for a diagnosis but was just curious if anyone had any tips or maybe I'm missing something completely obvious.

Thanks!
