Hi Everyone,


Flash isn't working? No worries. This article will help you to understand what is the source of the issue and how to solve it.


There are two main problems that can appear: power issue or connectivity issue. In order to make this first diagnosis, press on the flash's "Test" button (different in each strobe flash brand and model).

>> If the flash is not working at all, it may indicate a power issue.

>> If the flash is working, it indicates connectivity or a camera issue.

If your flash is firing for no apparent reason ("by itself") or when another photographer in the room is taking a photo - disable the Salve Mode in the flash.


If you couldn't solve the issue with the following troubleshooting guide, you're at an event and need a temporary solution - Increase your camera's ISO setting. If it's not bright enough, you can try to lower the Aperture and Shutter speed

Power Issue:

  • Make sure your flash is connected to the power.
  • Try to change the power outlet.
  • Try to replace the flashbulb.
  • Check the flash's fuse.



Connectivity or Camera Issue:

  • Make sure that your camera is in M (manual) mode (on the camera's dial).
  • Make sure the Slave mode is disabled (usually an eye-icon button on your flash).
  • Make sure that the sync cord and hot shoe are connected and tighten. 
  • Try to disconnect the sync cord and the hot shoe and reconnect.
  • Try tightening up the connection between the hot shoe and the camera with a little piece of paper or toothpick.
  • Try to replace the sync cord and\or the hot shoe.
  • Check if there is a setting in your camera that blocks the flash. If you want to be sure, you can reset your camera settings (Menu > Clear settings) and re-set the camera settings to the recommended ones.

  • Flash and Live View: Some Cameras will not activate the flash when the Live View feature is in use. If you are using the Live View feature and the "Hide Live View on Stop Live View" box is enabled in the Features tab, uncheck and see if the problem is solved. 
  • Make sure your camera has a normal hot shoe mount and not a stripped-down one. That kind of hot shoe mount does not sync with the flash unit properly.
