Hello I had bought a P3 4K used with the knowledge it did crash and the camera needed work. Guy assumed it was the cable. Drone shows no damage from crash and I have now replaced the cable twice to be certain issue is not from inexpensive cable used. Gimbal does standard start up dance but no image and does not recognize and sd card inserted. Like to get this drone repaired as have 8 going on 9 phantoms 7 are various versions of the 3 series. Unfortunately only have one 4K version so lack opportunity to swap parts to find problem. Any help with this is welcome and thank you.
