I have a mavic2 zoom, when powered on  it has no lights red/ green on the arms. Battery light comes on, gimble moves and centres and propellers adjust. Also it won't connect to controller. Any help would be appreciated.  Also Battery's are good and fully charged.

I would recommend you refresh the firmware using DJI Assistant 2 on your PC
