"SB600 Firing Accidentally"


Gold Coast, AU
          

I don't use my SB600 often so store it with the batteries removed to prevent leakage.
Now, upon reinstalling the batteries (which are fresh) the flash is firing accidentally, about every 10 seconds even when off camera. I have inspected the terminals and they look fine. I have also tried the 2 button reset and another set of new batteries , but the problem is still present. HELP

Hi Peter,

Make sure the test button isn't jammed in.
Is there anything that could be shorting the electrical contacts at the hotfoot?
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Thanks Marty. The "test" button still needs to be pushed to fire the flash. I can't see anything shorting out the hotfoot contacts either. When switched on, flash still keeps firing about ever 20 seconds or so.

Hi Peter,

The only other possibility that I can think of is an internal short somewhere in the Speedlight.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Hi Peter.

Sorry you are having difficulty.
I Googled and found this:

Pretty simple issue as it turns out. The flash has way more leverage than the bracket can stand over time. As such, it bends up the flat sides of the camera mount and the flash wiggles inside slightly. It's just enough to cause an electrical short between the camera hot shoe and the flash and it sends a signal to the flash to fire. All I did was carefully tweak the hot shoe so that it would be tighter when the flash slid in. Now that I've done this, it made me come to the conclusion that the way Nikon does their hot shoe mounts is pretty friggin' stupid.

It was submitted to Model Mayhem site by 'Shot-By-Adam'.

Hope it helps.
Terry.

The only thing is that he said that it is happening off camera as well.

My thought is that, if in commander mode, there are other lights causing the flash to fire.

Probably not in commander mode though if on camera, but if the settings weren't changed...

Thanks Charlie.
Yes the flash is still firing away without any input from me.It does this both ON and OFF the hot-shoe of the D7K.
I have checked the CSM setting on the flash and it is "OFF" .
My ND7K is NOT in Commander mode either.

I think I may have solved the problem. I suspected that condensation/moisture may have been the cause so I tried to dry out the battery compartment using sachets of desiccant gel in each of the 4 battery slots. This didn't seem to help so I placed the SB600 in the refrigerator for a couple of hours (with batteries removed). I left the battery compartment door open. Upon re-insertion of the batteries, the SB600 seems to be ok. The dehumidifying effect of the refrigerator seems to have done the trick

Thanks for your help and interest guys.
I just wish I had sorted this out a week ago, as I had to make do with the inbuilt flash on my D7K at a friend's graduation ceremony yesterday.
I am happy with the results but feel they may have been a whole lot better with a functional SB600.

My SB-800 was firing like yours. The problem I had was that I used a flash bar and the cord that attached to the hot shoe had spread the camera hot shoe slides apart. When I attached the flash, there was this slight rocking motion between the flash and the camera and it would cause the flash to fire everytime I moved the camera. I sent the camera to Nikon for repair. The cost was around $120 (more or less), but along with repairing the hot shoe, they completely cleaned the camera and put new rubber grips on that were coming unglued. I was very pleased with Nikons service.
