I have read online about many complaints of no transmission signal that go back a few years, but no answers. It is strange that this problem has been going on for a couple of years and no one apparently has found an answer to the problem. I hope I'm wrong, but I haven't seen any answers. I have reviewed all the answers here and on other sites and other than simple fixes such as reformatting the disk or removing or reinserting the disk, etc. I haven't found any answers to my problem. The camera works. I can take pictures and video when connected, but I can't see what the camera is seeing until I view what is on the disk after the flight. The camera tilt works. The P3S works and everything else seems to work except for the lack of an image on the phone. It did work twice for a short time when testing without props but I couldn't get it to work again. Does anyone have any ideas? Thanks for reading.
