As some of you may or may not know the Sony hotshoe is different to other brands. Becasue of this I needed to get myself an adapter that connects my 42AM external flash to my PT04 receiver.

Problem is the flash wont fire.

Trigger and receiver are working as they should be. Im getting signal when I press the test button on the trigger and the shutter button on the camera. ie. the red led lights on both the trigger and receiver are flashing consistently each time i fire the test button or the shutter.

The trigger/receiver are also working fine on my monobloc head ( albeit in this case the receiver is connected to the head with a small sync patch cord)

I think its either a faulty adapter (flash > receiver) or there is a compatibility problem with the adapter and the 42AM.

Any other ideas ??

oh and the flash is working perfectly both on camera, and off, in wireless mode.
