got Phantom 4 pro back from DJI Drone Service. Gimbal needed replacement. I had completely lost image transmission on the drone. When I went to check the drone out, I got the drone and controller back in sync, and had the live image on screen. However, I have no camera or video functioning at all. All of the settings across the top right say NA. I cannot switch from still to video either. The drone is just a flying toy at this point. I can't get an answer back from DJI Drone service, and DJI support just says to update firmware. Firmware is current, Two other things, the drone is blinking red and green on the light that is used for linking the craft to controller. And in the aircraft status menu, it says that the gimbal is disconnected, even though it is working....aircraft fly's fine, it is just the camera....any help would be most appreciated.
