Nikon Sb600 does not fire every time

I have a new sb600 and it does not fire every time. I have changed batteries. I use rechargeables...and when the salesperson told me that it might be my batteries - I bought another brand of batteries. But after 10 or 15 shots in 10 minutes the flash fies only sporadically. What is wrong?

    I own Nikon Speedlight SB-600 TTL Flash for 2.5 years now. Recently it started to malfunction in the following way: it became much slower and even after the ready light is on I take a picture but the Flash comes out very weak. Actually one out of 4 pictures the flash light is OK all the rest it's not working. I thought that my rechargeable batteries may cause the problem so I replaced them to the new ones but the problem still remains.

    I suspect that it's a capacitor and I'll probably will have to buy a new flash.

    I've had my SB-600 for 2 years now and have only just started to dabble more in flash photography. I noticed the same problem with the flash not firing every time even with about 5 seconds between each try (I press the flash test button on the flash itself without a camera) and fresh batteries. The ready light is on all the time and the times where the flash doesn't go off, the ready light goes out and comes back in once. Looks like I might have to take it to a camera repair shop.

    I have the same problem! Absolutely not a battery problem... Everythign works fine for a moment, and then, although the ready light is ON, the flash just doesn't fire one or two times! Very annoying for people portraits!

I know you mentioned rechargeable batteries, but you did not say was what kind. I have had my -600 now for more than two years and suddenly I started to experience flash failures, and the ready light would not come on to indicate flash is ready. I called Nikon 24/7 tech support and they recommended NiMH rechargeable batteries. (I was using regular alkaylines). Instantly my problems were solved, flash after flash it recycled instantly. In the manual they list the recycle times and the NiMH are the fastest. The tech said they were very good on power.I was skeptical, but he was right, it turnes out.

So, if you are not using NiMH for rechargeables, that could well be your problem. NiCads won't cut it!

My NIkon SB600 is stuck on my hotshoe-I can not remove it fromt the camera (d80) help

I had a similar problem with my SB25 when I tried to use it on a D90. I took the camera into the Nikon USA Repair Depot in Los Angeles where they took it into the back shop and removed it while I waited without charge. If the SB600 is like my SB700 and SB900's, there is a spring loaded dimple in the camera's hot shoe that clicks into a hole in the SB flash hot shoe. I think if you can slide a thin piece of metal such as a machinists shim, you may be able to depress the dimple and release the SB600. Let me know if it works.

Nikon Speedlight SB600 will not switch on

I'm sure this won't work for everyone but I used a long thin flathead screwdriver to scrape some corrosion off of the contacts that would be touching the positive side of the battery and then it fired up fine.  I'll use some swaps dipped in alcohol to give them a better cleaning later but after the scraping (gentle) it fired right up.

SB600 Works Erratically...

If red light on flash is blinking, flash is charging. In shooting rapidly, sometimes flash will go off even though it isnt fully charged. This can give dark shots. Flash eats batteries like crazy, best to always use fresh batteries for each shoot.

Sb600 doesn't fire well off the sb800

The sb600 needs to be able to see the preflashes of the sb800, so this is probably caused by one of two things.  The first thing I'd check is whether or not the light sensor on the side of the sb600 was covered, blocked, or facing away from the sb800.  I've had problems outdoors when I forgot to have the light sensor face the camera.
If the sensor was facing the camera, it is possible that the flashes didn't have a good line of sight to each other.  That normally shouldn't matter, but if there is a high ceiling and lots of people, it could be the case.  I don't know if it will help, but in any case I would recommend using a StoFen Omnibounce on the sb800 to increase the likelihood that the light finds a direction where a surface to bounce off of is found.  
Good luck.

Nikon SB600 flash behaving strangely

I have sent my SB-600 to Nikon twice in the past 6 months to resolve this problem. They have fixed it both times, but never told me what the problem was. I've had it back for exactly 1 day now, and it's started back up again already. If I receive a solution (or replacement), I'll let you know!
