My sb 20 nikon will not switch on, any help...this has been left for sometime and now it will not function anymore...any help...

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.

Assuming you have the Nikon variant of the flash, it should do anything the D5000 can handle. It won't work as a Commander, so if you need that functionality you'll have to get an SB-900 (or an SB-800 if you can find one).

bulb is gone replace the flash bulb near by service centre

It sounds like you're trying to use the SB-600 off camera, as a slave flash. While the SB-600 does indeed have slave capability, the D40 does not have the ability to function as a commander. Thus, the SB-600 is being triggered by the D40's pre-flash.

As stated above, the D40 does not function in commander mode. You can mount an SB-800 or SB-900 flash unit, which will function as a commander as well as a flash. Or you can mount an SU-800 commander unit.

Alternatively, you can switch the D40 to manual flash mode so as to eliminiate the preflash. However, you will then have to calculate the proper exposure yourself.

1/125 of a second, according to Nikon, but I've found on my N8008 that using 1/60 is more reliable.

if you use one of Nikon's dedicated Speedlights (SB-24, SB-23, SB-22, SB-20, SB-18, and SB-16B) then they set the synch speed automatically.

Your flash needs to be opened.There is a small pin which must have got stuck. In SB 800 we need to open both upper and lower portions of the flash. If you are good at opening gadgets, just try with proper tools. Careful not to touch the main Condenser terminals. If you are in India, I can help you out. 09341932677

Hi Kathy,

Are you ready?

1. Make sure the Nikon SC-29's Red Panel's Lock Switch is set to the Left. Pointing at Left Black Screw.
2. Connect the Nikon SC-29's (Red Panel) to your camera's Hotshoe by pushing it as far as it goes.
3. Turn Lock Switch to the Right (turn CW). This locks down to camera.
4. Make sure Nikon SC-29 (other ends) AF-ILL is set to OFF.
5. Make sure your Nikon SB-800's Lock Switch is set to the left side.
6. Attach your Nikon SB-800 into this Hotshoe.
7. Switch the Lock Switch on flash to the right.
8. When you wants to AF from flash, set AF-ILL to "OFF"
9. For the best results, set AF-ILL to "ON".

I teaches, do repairs, services and modifications on all photographic equipments.

I hope they are helpful to you as well as for any Nikon Photographers using the Nikon SC-29 Cable.

Mine has Autofocus, ITTL, Slave and Wireless Radio Remote Flash.

I struggled with this one but then, on the basis that if all else fails read the manual I found the answer. It's soooo simple. The wide-flash adapter is set. That's the little pull-out screen at the top of the flash which folds down over the flash-head. If it's pulled forward it activates the wide angle setting automatically. Push it back in and you'll be fine. tony k

In whacky situations like this it is always best to re-set your camera and flash settings. Somewhere on your D80 you will find two function buttons with small green dots next to them. These are the resets. Push both in at the same time until the display LCD flashes.. The camera is now reset to default settings.You will now have to re-set your FV button to the custom setting you had it at before.

Also, reset you flash by turning on the power and removing the batteries and re-install them.

Switch camera off and remove batteries. Leave for half an hour. Re insert batteries switch on set to flask and hold to ear. Can hear a whistling [This is the Flash charging up] If you cannot -assume the flash unit has failed. Now go to the Manual - A full version is in a PDF file on the Disc. Check through that you are doing every thing correctly. If still no lick Nikon customer support will advise your next move. The likely hood will be that if the camera is over a year old they may offer a discount on a replacement. A repair is not likely or very pricey.
