Question about Nikon Speedlight SB-600 TTL Flash

Nikon Speedlight SB-600

The only way to bring my Speedlight to life is to squeeze the battery chamber lid. My speedlight's batteries had run out and I didn't use it for a couple of month and I just left the old batteries in it. But when I changed them, it acted like it didn't have any batteries in it. When I started to open the battery chamber lid, the LCD panel flashed on for a split second. then I found that the LCD panel would stay on it I squeezed the battery chamber lid. Even then, I can't get it to flash. I tried cleaning the battery contacts with an eraser, but with no success. The speedlight isn't even two years old and is stored in a safe container. I am stumped.

    I almost the exact same problem. Been using the flash constantly - batteries wore down (not completely) - replaced with fresh set - now contact with them is flaky - can make contact with the lid - but can't sustain contact with lid properly in place

    Yes... I had the exact same thing happen with mine. Even though my contacts looked like they were in good order, I clenaed them and the ends of the rechargable battries. Seems fine now. still would like to know for the problem though.

    Exact same problem - I mean exactly the same story word for word. Still can't get it to work.

    Almost exact same problem. In my case, if I hold the battery cover partially closed, the flash works. If I close it all the way, I get no power. The contacts weren't bent or flattened, but I tried bending them up to increase spring pressure with no luck. The flash still behaves the same way. I'll try cleaning the contacts, though they look fine.

    Exactly the same problem - sometimes putting selotape round the "not quite closed" cover would solve the problem, sometimes it wouldn't. The manual says that if the flash gun doesnt work first time turn it off, take out the batteries and then replace them and switch it on again. This is all very well, but since the on/off switch doesn't actually tell you if it is on or off, when you have put the batteries back its difficult to know whether the problem relates to poor battery strength, poor contacts or the fact that it is actually switched off. I haven't tried the eraser trick yet, but how do you clean the contacts in the bottom with an eraser - one on the end of a pencil?

    The same thing happens to me on my flash, where I think I put the batteries in the wrong way and then I go to open it and it will flash on and stay on without me powering it up. Then when I go to shoot the flash it will work a couple of times and then the flash won't go off about 3 times, I have used the ready button to see how many times I can get it go flash consecutively, it will go a couple of times and then it won't a couple, it is very frusterating when I am shooting a wedding.

    Well these are old comments and this EXACT problem is still going on....I have to push on the battery compartment and then I hear it fire up. I will try the eraser cleaning, but I have looked in with a flashlight and a magnifier and the contacts are squeaky clean. I also pulled up the contacts a hair and it worked on day, but the same thing happens again. I want to send all these blog entries to NIKON, what do you think?

I had the same problem - used an eraser to clean the contacts and it worked perfectly

Exact same problem. Bent the contacts inside the flash to push the batteries up closer to the lid. Also cleaned the lid contacts. Seems to be working now.

The contacts weren't bent or flattened, but I tried bending them up to increase spring pressure with no luck. The flash still behaved the same way. I then cleaned all contacts thoroughly with a brand-new eraser, blew out the eraser dust, and the flash seems to work fine now. I cleaned both the contacts on the cover and the contacts at the bottoms of the battery wells.

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.

Nikon Speedlight SB-600 won't flash

Hello Friends,
I have SB-600 Speedlight. it dropped from my hand , from then, it goes to READy state but didn't flash.
Please help me to find a solution for repair it or any tech service with resonable rate .

I have a Nikon D40x with a Nikon Speedlight SB-800. The speedlight is not working. I have the camera on, new batteries in the speedlight and speedlight on. Not powering up. Is there some secret battery...

With new batteries in the flash, and it being off camera what happens when you press the test button. If still it does not flash call Nikon 1-800-645-6689

I have a Nikon Speedlight SB-600 that needs repair. The flash does not operate. I believe there is no connection made with batteries.

Check the battery contact make sure they are clean. If a battery leaked, even a little battery fluid on the contact then that could be the problem.

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.

SB 600 Not resetting...

my sb 600 speedlight won't turn on. Do I need to reset it? It has fresh batteries. Never been dropped


Problem with SB-600!!!!

Batteries may have leaked. Open battery chamber and clean ---especially the contacts situated at the bottom -- with pencil erazor. Blow out any loose bits and with new batteries try to switch the unit on.

My Nikon SB-600 speedlight seems to have died - only had it 2 years. Could it be because of battery leakage - I found some suspicious looking wet-stuff inside the case. Batteries haven't been there that...

You may be lucky because the battery acid may not have gone beyond the contacts in the battery chamber: open battery chamber and clean out especially at the bottom of the chamber and blow out any loose stuff when you finished cleaning ( use pencil erazor or something similar , but do not use sand paper or anything that will damage chrome plating of the contacts ; you do not want corrosion at later stage ).
