Suddenly lost video feed after working normally. No crashes. Tried turning on things in different order. No help . Get gimbal disconnected message on main Dji app page but can control camera tilt via the wheel. Reset all to factory in the Dji app menu. Different battery and different sd card. Used different iPads and even Tablet S and still no video. Ran IMU and camera gimbal setups and calibrations show ok. shows latest firmware installed on my Phantom 3 Std. Uninstalled and re installed DJI App. Tried different location although I live right on a lake. Can fly normally but with no video feed. All wires look in good shape and connected. Anything else to try ?
