Phantom 4 Pro plus. After being unable to connect to the aircraft with the Go Fly button on the remote. My work around was to start just the remote, I then press 'Enter Device'. Once in, I then fired up the aircraft, they connected but I had a fast flashing (groups of three flashes) red LED next to the SD card. I had no video transmission at all and a fault came up 'Camera sensor issue, contact DJI. Everything else seemed to be working and I could fly the aircraft. Research online suggested to buy a new gimbal cable which I did. I very carefully installed it following a tutorial on here. Now my connection problem has gone away and when I press the Go Fly button in connects straight away, there is no camera sensor issue or any other issues reported, but I now have very bad Stuttery, partially frozen video, totally unusable transmission and recording. Any Help really appreciated.
