Flash has stopped working on my Nikon D40. I've tried a factory reset, tried to get to the flash setting but that menu option is no longer available (highlighted) in any mode. I'm thinking it's broken and not a setting thing. Everything else works fine and it still takes pictures just without the flash. The flash pops up when needed but no flash obviously.

turn it on go to menu custom setting menu then braketing /flash then toggle right and turn it on

Hi,

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.

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.

Goodluck..

kindly see the aparture and speed of xpouser and the iso also if the iso is 100 change the iso to 400 or 800 or u can select he programme option for the best xpousers

Make sure you have read your user manual and know how to use the camera, including how to use the flash.
Go to the menus set all settings to factory settings. Later you can set them the way you want. Make sure all settings are set to make the flash work when you want to use it. Some settings will turn off the flash.
If you need technical support or repair consider calling Nikon. Go to nikon.com and browse to the support section, find the repair and the toll free number. Call and see if you can get help on your camera.
Nikon has an up-grade or trade-in program for refurbished units if your repair is too expensive.

Try turning camera on,
Then press both Green buttons for a count of 10. This should restore factory reset.

Some models also have a reset button under a connector flap, or go into your menu. Under Custom Setting Menu, choose Menu Reset.

One of these methods should work.

There is no top LCD on the D40. Put the camera in AUTO mode (green icon on the dial) and take a picture in the shade. if the flash does not go o, then you have a fault. Send back to authorized repair centre. 

Try resetting the camera back to the factory default setting.
Remove the battery, leave it for 1/2 + hour, insert the battery and configure date time etc.
If it doesn't work then you have faulty camera.

Hi,
I know some of the common things for the digital camera. I want you to try these.

-------->If the built-in flash does not function, then the camera may be set to Auto and will only flash when taking pictures in poorly illuminated environments.
-------->Set the camera to the Forced flash setting so it will flash regardless of the surrounding brightness.

IMPORTANT: If the Forced flash setting is already enabled and the flash is still not working, then the issue may be due to another camera setting. Even if the Forced flash setting is enabled, the flash will still not work in the following circumstances:

* When shooting MPEG movies
* When set to the Twilight mode
* If an external flash is connected


The information above should resolve your issue. However, if the issue still persists, you can try resetting the camera to factory specifications.
Some cameras have a RESET button built into them or a menu option to reset the camera to the default settings.
Refer to the instruction manual supplied with your camera for specific information regarding the availability of a RESET button or menu option to reset the default settings. Otherwise, continue with the manual reset procedure below.

1. Turn off the camera.
2. Ensure the camera is not connected to an AC power adapter.
3. Remove the battery from the camera for 15 seconds.
4. Reinsert the battery.
5. Turn on the camera.

If all the above fails you, then i doubt that Impact damage would have caused the flash not to work.
But i know you are not going to like this solution. No other way , you have to contact Nikon service centre for repair.

i hope this helps to fix your problem.
Thanx for using fixya.
Cheers.

The lightning bolt icon in viewfinder blinks when flash is not ready, this can happen if flash doesnt pop up all the way, or if flash strobe tube is bad.

If lightning bolt icon is blinking in viewfinder, flash is not ready. Either flash isnt popped up all the way or flash strobe tube is bad.
