A few weeks ago my trusty Nikon SB-600 flash unit stopped working. I
sent it off to the Nikon service agent (700 miles away) and they
reported that after they cleaned the battery contacts it was working
OK.

I tried to use it again today and everything was working properly -
right up to when I try to take a photograph. All the right things
happen in the window, including the little red light blinking as the
capacitor recharges. But no flash.

The problem is probably the flash but I want to prove that on another
camera. The nearest suitable camera that I know is some 30 miles away,
right through the heart of Auckland. The owner works rather extreme
hours so it might be a week before I get to try it. In the meantime I
would be interested to hear from anyone who knows the workings of
Nikon flashes. What is the most likely problem?


Did you try the flash test button?

You can briefly short the centre pin on the flash to the ground - that
may prove that at least the flash works. Pro tip: don't look at the
flash when you do this.

Whenever anything that uses cell batteries doesn't function, clean all
the contacts with an abrasive. Make sure all the dust is recovered
(vaccuum is best). (This means the battery compartment and the batteries).

Connectors (flash shoe on camera and counterpart on flash, etc) should
likewise get the treatment.

Abrasives can be emery cloth, fine sandpaper, Scotchbrite. Don't use
metal abrasives like steel wool. You may need to be creative to get
into nooks and crannies.


nikon did all of that (and more) and said the flash is working properly.

the problem is not the flash.


Allegedly.


there's no reason why nikon would lie about what they did.

Further, Nikon did not clean the contacts on the camera, and
above specified battery contacts, not show contacts. Missing info
perhaps...


like i said, there are three possibilities.

the flash has been ruled out, which leaves two others.
