When my Phantom 3 Pro boots up the gimbal does its dance... looks good but NO Video and the unit displays G Disconnected. If I touch the camera it swing down and cannot be controlled by the RC. I have NO picture.... HELP!! One other symptom... When I turn off the Battery using the standard process click and release and click and hold the button down... now I have to do it twice to turn off the unit. The RC works fine.
