Question about Nikon Speedlight SB-800 TTL Flash

SB-800 Going Crazy

Hi.  My unit (shelved for several months) is not working.  When initially turned on, nothing works.  Then it won't turn off w/o removing batteries.  When turned on again and mounted onto my D40, it keeps flashing continiously.  Tried resetting everything.  Tried unlocking.  Nothing works.  Will not sync/talk with camera when remounting and it is not flashing continiously. Unit is almost new having shot about 200 frames.  Time to send for servicing?  Can you help me please. Thank you. Jay

    I got the SB-800 and I got the same problem. The moment I shake it softly when it's attached to my D200 the flash and infrared fire.
    I don't know what to do.
    It would be helpful if someone came with a solution that does not require bringing the flash to a servicecenter. :)

Using SB 800 flash Master with 2 SB 600 as slave


Hi Frank, I use the same combination of the exact three flashguns you have. Works beautifully. I mount the sb-800 on my camera and set it to Master Mode (press and hold the center button till the menu comes up, select the master). Set the other two sb600s as slave. Please make sure the channel is set the same in all three flashes... when positioning the slave flashes, make sure that sensors on the remote will recieve the light from the main flash. For maximum coverage I use the sb-800 with a diffuser in bounce mode. You will be amazed at the quality of interior phots you can get with a 3 flash combo.

Ready light on my SB-800 speedlight


put in a fresh set of batteries. The ready light won't turn on until the flash capacitor is fully charged. And if your battery is weak, it can take very long (minutes!) to fill the capacitor. You still can fire the flash even it is not ready, it will just dump whatever power it stored in the capacitor.

Sb600 wireless mode not working...


Remember that even though sb-600 is wireless, it is based on infrared. This usually means having a clear line-of-sight between flash commander and remote flash. Any object that gets in way can block signal from flash commander. Weak batteries in flash will also cause remote operation to be sporadic.

Speedlight SB-600 Display flashing.


My SB 600 is doing the exact same thing. I used Nikon's online support service and this is the response I got: "I would try doing the 2 button reset on the flash and then see if that helps. Also disconnect any battery packs you may have connected especially if its a third party battery pack. If none of the above work then please service the speedlight" Sounds like they don't know what it is, either. I tried the reset to no avail. I'm not sure I want to send it in to have it fixed, since it does seem to be working. But you're right, it's annoying.
