So I was on a shoot yesterday, everything was working fine, until suddenly the recycle time on my flash increased. Like I could normally shoot in burst and not have an issue, but now its like 1-2 seconds between charges. I also can't change the power of the flash. The number changes but the flash itself fires the same, and its as if its firing on 1/1, even its its set to 1/128. I've tried everything I can think of to fix it but I'm not having any luck. Can anyone help?
