I have a Phantom 2 with H3-3D, OSD, DJI Video Link and the DJI data link. After a mellow crash I no longer can get video signal but the OSD still displays on my screen. What should I check/replace? Do I just replace the transmitter? Transmitter antenna? I've always had some flickering with the video link regardless of the distance, even if the camera is 5 feet away. Could wires be touching? Could my antenna be damaged? I shoot video professionally but I'm new to RC filming so any help is greatly appreciated. I've got a real estate shoot on Sunday and would love to have my FPV dialed so I can get the exact shot I'm looking for. Thank you so so much for your help!
