Nikon D40 - The built in flash will not ppo-up in auto mode. The only time it works is the manual modes. Are there any settings I don't know about. I'm calling it defective and will return it the store.

The Nikon Coolpix is a compact digital camera that is well-suited for amateur to semi-professional photographers. Occasionally, some issues with the built-in flash can occur. If the hardware is damaged, the camera must be taken in for repairs. More often, problems occur because of obstructions or issues with the camera's settings and are easily repairable. Follow the troubleshooting guide to fix the built-in flash.

Instructions:
1.Ensure the Nikon Coolpix digital camera battery is fully charged.
2.Wait several seconds before pressing the shutter-release button if the "Flash Ready" indicator light is flashing red. Press the "Flash Mode" button once or twice to change the flash settings from "Off" to "On" or "Auto" if the "Flash Ready" indicator light is off.
3.Ensure there are no obstructions, like your finger or the camera strap, that are preventing the flash from firing if an error message appears on the display screen and the flash is not firing when the flash mode is set to automatic.
4.Press the flash back into the camera after every photo to ensure the flash always fires in "Auto" mode instead of just in low illumination settings. Press the flash back into the camera to turn off the flash in "Manual" mode; otherwise the flash will continually fire.
5.Change the auto focus setting from "Infinity" to "Auto," "Macro Closeup" or "Self-Timer" by pressing the "Focus Mode" button once, twice or three times to automatically turn the flash back on.
6.Use only Nikon external flash accessories to avoid damage to the built-in flash and camera circuits.

I hope you find it very helpful. Thanks.

Set the exposure mode to Manual (M) or Shutter-priority (S) and specify the shutter speed yourself. You'll have to set it sufficiently slow in order to see any difference between front- and rear-curtain.

on the side of the lens check to be sure it is set to auto and not manual.

Turn off the flash manually (top left button on the side of the camera body above the lens) or use the 'No Flash' Program Dial option - one click back from the green AUTO selector on your dial - the one with the lightning bolt inside a circle.

I don't know what you are doing - mine shoots continuously with no problems. There is nothing to set other than to set the shooting mode.
I have noticed that some memory cards are so slow it doesn't allow continuous mode. I recently replaced mince ith 16G class 6 cards and they work fine.

You have your camera set to RAW format. It is not a compressed file, it is a full size file. Opening this in editing programs will either crash your computer or will refuse to open because of the size of the file. They are not damaged but your computer cannot handle the files. You should take them to a photo shop and have them put the files on a cd and consult your manual to change your camera to JPEG format.

Hi and thanks for coming to FixYa.

You can set the parameters for the manual flash in the Custom Settings Menu. Select Full to set the manual flash adjustments.
Hope this helps. Let me know if you have any questions in a comment.

white balance can only be manually configured on "PSM" modes only, the other modes set the white balance automatically .

When the camera is in auto focus mode, it will not take the picture until it locks onto a subject. If there is not enough light, the camera will "hunt" for something to focus on. Since it can't define any edges, it won't allow the shutter to release.

The D40 base model does NOT have a powered focus lever for autofocus, so if the autofocus is not working, suspect the lens.

Sounds like the external flash is being triggered by the pre-flash.

On the D40 set the flash mode to manual. On the F65 set the flash mode to Standard TTL.
