Nikon SB-600 Troubleshoot. "--" appears.

[kristyboox33]

I bought the Nikon SB-600 speedlight about six months ago and I came across this trouble shoot. When I attach my speedlight onto my camera, "--" pops up on the zoom-head position indicator. In the manual, it says "a zoom-head position adjustment error has occurred. Turn off the SB 600 and camera and detach the SB 600 from the camera. The, reattach the SB 600 to the camera and turn on the power." I've done it many times and still doesn't take the "--" off. I've tried cleaning contacts on the camera and flash, and I've also tried resetting the settings on both. This is frustrating. help?

Make sure the little plastic diffuser is pushed all the way back in. If it is out slightly, it will only be at the widest zoom.

didn't work, but thanks.

Might need service.... I think I read somewhere that you can reset the onboard chip by removing the batteries and reinstalling them while the flash is on..... If that does not do it, then it would be time to contact Nikon service

Try the hard reset as Scooter described. If not successful your diffuser switch is broken. This a common problem with speedlights from Nikon. Usually happens when the flash is dropped can even occur when dropped on carpet. Jim
