WORKAROUND for this Problem: I have the same problem with the flash only firing once...kinda. Gear: Sony a6000 560TXII [A] New 560 IV bought brand new from B&H Used 560 IV bought used from ebay [C] Used 560 IV bought used from ebay With the 560TXII, Flash A will always be triggered every time whereas B & C will only fire once until something is changed on the 560TXII. If I use the TEST button ALL will fire ALL the time. If I put the 560TXII onto an old Nikon in the hotshoe ALL Flashes will fire EVERY time. If I mount Flash A directly on the Sony and set it to TX then both other flashes fire every time. If I mount Flash B directly on the Sony and set it to TX then Flash A fires every time but C only fires once. I can only assume that there is a difference in the manufacture of the new and used ones. I wish there were serial numbers on the units to see the date of manufacture. I did figure a work around though, Place a bulldog clip on the 560TX and apply pressure to either the "GR/*" or TEST button. All flashes will fire every time, to change the flash power remove the clip and adjust. Not ideal, but acceptable for me when line of sight doesnt work on a real estate shoot where the flashes are in different rooms. Hope this helps someone out there! M.
