Hello photo people! I have a relatively new D3100. All of a sudden the flash won't fire. I have tried most setting and nothing. I tried Auto, the selector switch is set to Single Picture and I'm in a relatively dark space and no flash.
In the view finder the flash symbol is flashing and so is the question mark and a dot. In other settings I make sure the flash is set to auto flash...nothing. HELP!

1. The lens focal length is less than 18mm
2. The D3100 thinks an external flash is enabled
If you're not using a wide-angle lens and haven't used a speedlight recently, then I would reset your in-camera settings to default. You can do this by pressing the MENU button and navigating to the 'Shooting Menu' tab. Once there, you'll see 'Reset shooting options'.
After you've done a reset, make sure your battery is fully charged and try taking a test shot in Auto mode with the flash enabled. Let me know if that works for you.
