Question about Nikon Speedlight SB-600 TTL Flash

1 Answer

Intermittant flash firing.

I have a SB 600 flash. The moment I insert the batteries, the flash starts firing in a periodic manner with an interval of say 30 secs. I tried resetting the flash but to no avail. This happens without the flash being connected to the camera. Pl advise.

    Same problem, once i put batteries on, it fires every 20 seconds, or everytime is fully charged... can i send my flash back even if its not under warranty any more?

    To whom it may concern,

    I am experiencing the same problem and actually stumbled upon your problem while researching mine! I just got this flash brand new for christmas and it's already acting up on me. Not gonna lie, I'm a bit disappointed. I've borrowed SB-600's from friends and had absolutely no problems what-so-ever. I guess I just got a lemon. Anyways, since the camera is only two days old, it's obviously under factory warranty. So the next best thing is to send it in to them - how inconvenient considering new years is only a few days away and i was looking forward to using it then :(

    I have the same problem - the flash fires continuously as soon as it's charged (every 20-30 seconds). Started happening after dropping the flash on a ceramic floor from about 4 feet. There is no visible damage on the outside, but I'm guessing something is shorting out inside?

The main cpu is bad and you need to send it back to the factory.

MY SB 600 wont fire. I replaced the battery already but If I test fire it, it wont flash.


If you tried multiple batteries that you know are good and the flash will not fire while on the camera or via the test fire button, this unit will have to be returned to Nikon for service and repair.

My Nikon SB-600 turns on but does not fire.


with any flash unit check that you hear a whineing sound as the unit preps to fire.
if you do not hear this then the battery may be low and need replacing.

i hope this helps

Bought a Nikon Speedlight SB-600 in August. Tested the flash and it fired ok. I took out the flash a few days ago to use at a graduation and the "ready" light did not come on. Consequently it did...


Hi grwcamp, Sorry to hear about it not working at the graduation. Are in the correct position (I am sure you did but, we must start someplace). Look inside, see if there is battery acid in there.
If with new/fresh batteries it still does not work call Nikon. You have a warranty on it so it should be covered.

SB 600 has stopped firing batteries are good


flash bulb could be burnt out...if it doesn't fire when when you push test, that's my guess as to the problem. Another possibility (although unlikely) is a loose connection in the flash.

Nikon Speedlight SB-600 keeps firing


I believe that there is a safety feature built in that if the voltage in the capacitor gets too large the flash will fire, to prevent damage, could be this that is faulty, if it is a new main circuit board is required.

My SB-600 Just quit firing... :(


It maybe because it overheated he flash tube, nikon flash guns use a thermal cutout, to prevent overheating, usually after approximately 30 / 40 shots, in quick succession.  It should start working again after it cools down.
If not you may need to get it checked at Nikon Service Centre. Cheers Ian

My sb 600 fires with the camera but it seems not illuminate


Definately a settings problem. The camera will only syncronize on one specific speed. Youe best bet is to use auto. For manual, you'll have to set the shutter speed at the sync speed.

Flash Sync Speed
  • up to 1/250 X-Sync Speed
  • up to 1/8000 FP High Speed Sync
  • Red-eye reduction
    Red-eye reduction with slow sync
    Rear-curtain sync
    Slow sync
    Front-curtain sync (normal) Flash Sync Modes
  • 1) i-TTL: TTL flash control by 1,005-pixel RGB sensor, built-in flash, SB-800, SB-600, SB-400: i-TTL balanced fill-flash and standard i-TTL flash
    2) AA (Auto Aperture-type) flash: Available with SB-800 used with CPU lens
    3) Non-TTL Auto: Available with Speedlights such as SB-800, 28, 27, and 22S
    4) Range-priority manual flash; available with SB-800 Flash Control

    SB-600 Ready Light Won't Come On When Mounted on D-40X


    Check that all the batteries are functioning properly, and that they have been inserted in the proper direction.

    Random firing


    Maybe try cleaning the contacts? Check that the contacts on the flash aren't damaged.
