Is my flash broke (remote trigger not triggering it)

[AshleyC]

Ive a Nikon, 2 Nissin flash's an 866 mk2 and a 622. Using the Yongnuo 603N triggers.

If i plug one into the camera and one in the 622 everything works fine. With the flash in manual i can set the strength and it fires when the camera does, great.

Plugging a trigger into the 866 though doesnt seem to do anything. Ive tried the flash in manual mode, TTL mode, wireless mode in Master and Receiver but nothing. I'm sure ive had it working with the flash a while back. The channels match up between camera and flash.

Anyone with this combination have it working ok?

I'm not sure if this will be of any help to you, I found when I use my slave that the receiver has to be pointed at the camera.

I know the Mk1 Di622 flashes had issues with triggers - i.e. they didn't work without a firmware update that was only available for the Nikon model - but I haven't read that the Di866 Mk2 doesn't.

Have you tried the flash mounted on the camera with no triggers involved?
Are the lights on the triggers flashing when they should be triggering?
Is the flash flashing but not appearing to light anything in the image or is it not firing at all?
