On my recent trip, I was taking flash pictures in a museum (temp 65 deg F and relative humidity of approximately 70%) when the flash failed to fire. When taking pictures, flash interval was more than 3 -5 minutes between flashes. Turned flash off and on a few times and the LCD screen did not light up. Put new set of batteries in and still no LCD screen readings. Tried again a few hours later while at the hotel and flash again worked and with the first set of batteries.

What was going on. Flash continued to work with this same set of batteries for the remainder of when I was using it.

Why did flash stop working? And was okay a few hours later?

Thank you,

Gritty

If you overwork your flash (lots of fast, weak flashes in a row or lots of full power shots as fast as you can take them based on recharge time) you overheat it. It will cease to work untill it cools sufficiently. Flash manuals tell you to avoid overworking the flash. By the way, if you overheat the batteries through heavy draw, they too can cease to work yet recover enough after cooling to still work.

I agree with what you said, but notice I said that there was a time interval of 3 - 5 minutes between flashes. There should not be a problem with flash overheating or battery overheating, I would not think. The day before, at another museum, I was taking flash pictures at the same rate and had no problems. What now?

Thank you,

just an information from my experience. Check the contacts between the flash and the camera.

I have had instances when the flash was not locked completely and the contacts were not constantly touching. Specially when the camera is held at an angle the contacts were not properly touching(My bad i didnt lock it properly)
