Hi, Happened today, was flying and filming and everything was ok. Changed battery, switched on Phantom, no video output from gopro. Switched off then on, nothing changed. I tried however to film, but gopro started recording and stopped itself after 6 seconds. So, no video output, no recording. I updated the gopro, now filming is ok but no video output from the Zenmuse, or the gopro. I have to sort this. Fatshark transmitter works, fatshark receiver too. Anyone faced this?
