Hi folks. Sending this out to the Wetpixel community. Recently bought a dual fiber optic sync cord for my new-to-me Nauticam D500 housing. Cord came today just in time for a trip starting Thursday. However, when I hooked the cable up I discovered that the strobes do not fire on the first flash, but that as long as the shutter is held down thereafter the strobes fire just fine.
In other words, when looking at the flash trigger inside the housing (rear of housing removed) the green LED at the top of the circuit board doesn't light up, but on the second frame and any thereafter it does light up and the strobes fire. Of course, if I pull my finger off the trigger for a few seconds the problem starts all over again.
I think the issue has to do with the flash trigger. In fact, I'm attaching a photo that shows some possible damage to the trigger just to the left of dip switches at the top. Thoughts?
