Why won’t my third-party flash work reliably on a Nikon D750 hot shoe?

My Neewer NW/TT 750 II flash used to work in TTL on my Nikon D750, but now it behaves inconsistently. The flash powers on and seems to communicate with the camera because settings are reflected on the flash screen, but the pilot/ready behavior seems wrong and it won’t fire properly. I’ve already tried resetting camera and flash settings, changing shutter speed, and different shooting modes. Could this be a camera setting issue, or is there a known fit/contact problem with some third-party flashes on the Nikon D750 hot shoe?

Nikon changed the hotshoe on the D750 (and later models), making it slightly too deep for a lot of 3rd party flashes to fit perfectly if the foot is pushed all the way forward. If you push a 3rd-party flash or transmitter foot all the way into the hotshoe, the TTL/HSS pins can lose contact and camera/flash communication can be wonky or not happen at all.

The basic hack to fix this is to:

  1. Seat the flash full forward in the hotshoe.

  2. Partially lock down the foot of the flash.

  3. Slowly pull the flash foot back until you hear the locking pin click into place into its hole in the hotshoe.

  4. Finish tightening down the foot on the hotshoe.

Alternatively, build a spacer for your hotshoe.

This is likely not a camera menu problem. A known issue with the Nikon D750 hot shoe is that some third-party flash feet don’t make reliable contact if pushed fully forward. The shoe can be just deep enough that the TTL/HSS pins lose proper contact, causing erratic communication or failure to fire.

Try this:

  1. Slide the flash fully forward into the hot shoe.
  2. Partially tighten/lock the flash foot.
  3. Slowly pull the flash backward until the locking pin clicks into the hot shoe hole.
  4. Finish tightening it in place.

That slight repositioning often restores proper pin contact. If needed, some users also add a small spacer/shim to improve fit.

Since your flash screen is reflecting camera info, the flash is at least partly communicating, which supports the idea of a contact/fit issue rather than a dead flash. If this method doesn’t help, then inspect the foot and hot shoe contacts for dirt or damage.
