580EX II not firing on a 5DII
Yesterday I should use my 580EX II on my 5DII hot shoe, after a long time of no use of the flash. It would not fire. I did a reset on the camera and on the flash but with no luck. The camera does "see" the flash and I might flash the flash manually. I have tried all modes on the flash. I eventually got it to work, but it is not stabile. When I change the direction on the flash it sometime does not work.
My theory is that there is something wrong in the connection between the hot shoe and the flash. Is there something I can do to fix it my self? Any workarounds? Any testing I should do?
Thanks in advance!
