Fmay nikon d40 flash in not working..

You might be shooting with a higher ISO or in settings where the D40 meter finds enough light and doesn't activate the flash.

Try changing the ISO to a lower one, like ISO 200 and take some test shots indoors, in a darkened room.

OR, you might have the mode dial set to "no flash". That's the crossed out lighting-bolt symbol. Just set it for P or another mode and you're back in business.

Hope this helps

Nikon D40x flash will not go off

I have the D40x. Only thing i can think of is the little sensor thing on the front down and to the left of the release button. If you have your finger over it, the flash don't work and the focus won't work right. "Infrared assist" in the manual. Myself, I use the sb400 strobe flash cause the popup flash uses too much power from the camera battery.

Nikon D40 shutter speed problem

The D40 will not take great photos of an indoor event without blurring or noise. You need a fast lens and a high ISO using the popup flash or on camera flash would be ideal but some of these events you can not use flash. All these images I shot with a Nikon D40. Learn to use the camera for ur events. Experiment it's all about trial and error. Ray

Flash won't fire

If it clicks when the flash is already open, it seems there would be a problem with the flash open sensor. The camera thinks the flash is closed, so it tries to open it again and it refuses to fire, because firing in the closed position would blow the bulb.

Here's a <a href=''>photo of the sensor in a D70</a>. The D40 flash is a bit different, but if you open it (just unscrew the two little screws in front) you'll recognize the sensor clips. Open and close the flash and see if the make contact when open.

(And DON'T fire the flash when open, or at the very least don't touch anything in there when firing or you'll get zapped.

You probably have "bracketing" turned on. In your menu settings, search for bracketing and make sure it is off.
