Hi there, I would like to know, which part of Phantom 3 Pro is respnosible for video transmission between camera and ipad. I got a used P3 Pro wich doesn´t transmit video, but I can take pictures or make video. I tried changing the camera with another from other phantom 3 and the problem was resolved. So I know now the issue comes from somewhere in the camera. Is the ribbon cable damaged? or is another part like a card from camera responsible for video transmission?, or what could it be?. How to know it? I would appreciate your comments and suggestions.
