Question about Nikon Speedlight SB-600 TTL Flash

Dropped my SB600

Hi - it's been sent to the service center, so I'll find out what is wrong soon enough, but if anyone would like to have an educated guess....

All "life signs" are good but flash won't fire. Charge light is on, screen display good, navigation buttons working, but only a slight 'click' when the manual 'flash' button is pressed on the body. And no fire in any mode when the flash is mounted on the camera.

Re: Dropped my SB600

I purchased the sb600 replacement tube from nikon and tried to replace it myself. I have worked with electronics and some soldering and figured i could handle it. It is very VERY finnickey to get the old tube out and even harder to get the new tube in without touching it with your fingers... once you finally get it in.. the wires are very short and hard to hold in place to solder. I resoldered it about 3 times and each time it still wouldnt work... and i only got shocked once..quite the scare..havent touched the thing in months...probably going to get a new sb600 since its 75% the price to get it repaired professionally..

Re: Dropped my SB600

It is possible, but highly unlikely considering that there is no real way to purchase the correct Xenon tube outside of Nikon's supply chain. Also, it would depend on your skill level in dealing with high voltage flash tubes - the electronic flash has a little high voltage power supply that charges up some capacitors (the high pitched sound you hear while it is recycling). When you fire the flash you discharge the capacitors across the Xenon tube which generates a plasma and gives of a pulse light. So, the truth is, if you are asking the question, it is probably not within your capabilities - though if you want to give it a shot, please make sure you discharge everything before attempting to do so. Even after several days, there will still be an appreciable voltage present unless Nikon has done something to protect you (doubtful). Also, you would need to pay extreme attention to contamination from skin oils, etc., so that you don't wind up ruining the high voltage part or blackening the bulb that you put in.

If you have a homeowners or renters insurance policy and the deductible is low enough, I believe that this would fall under one of those.

Good luck.

Where can I find a replacement flash head tilting/rotating lock-release button?

Hi Kaye, I reckon the only place you'll get one is from a Nikon Service Centre, or a discarded/broken SB600 from a camera shop.

I dropped my sb600 and now the flash doesn't work. The unit comes on, but no flash. Is it worth fixing?

there is no harm getting it looked at
it may be something as simple as the bulb is broken and needs replacing rather then spending however much for a brand new flash

Will not turn on

Make sure there is no battery corrosion on the battery contacts. If there is rub it off with a pencil eraser (nothing abrasive or it willget worse) until bright and shiney. If this does not fix the problem it should be sent off for service.

Nikon SB600 flash menu locked.

Nikon hot shoe is rated up to 250V (canon's is rated up to 6V) so you can use almost any tipe of flash, except maybe for old studio flashes.
Vivitar 283 (older versions) is ~200V rated, and much lower on newer versions. It should work.

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!
