I am having the exact same problem. And I have also the infrared hot swap camera and it does the same thing. My H+ is also doing it. I sent my H+ in for repairs and it came back with the camera not working.Hi all ! Yesterday I got my first Typhoon 'H' (not H plus, just H) and it all looks very nice. This morning I checked UAVforecast.com and found it ideal to do a flight test etc. While still inside the house, I did a battery check and found the video would not connect. I removed the camera/gimbal and slid it back on and tried it again. Same thing. Camera movements were great all around, so I knew the camera was getting power. I tried the video button and the snapshot button even though I was not receiving a video screen and it said NO SD CARD INSTALLED. I tried several of my 4K 3U cards Extreme and Extreme plus, not to mention the factory card I found in the camera. I downloaded the card and installed it again, and no change. Then I remembered there was no card in the radio, so for S's and giggles, I installed one in the bottom of the radio( whatever that one is for). No change. Still no SD card detection and no video, but, full camera movements. I went out and flew the drone and tested camera movements anyway without video and it flew great! I did the suggested SETTINGS on the radio and there was the camera listed. I tapped on the camera and then bind, and still no video. I tried everything I can think of. I wonder if the guy I got it from rebooted and clicked something off. I'm at a stand still as for what to do now. Not recognizing ANY SD cards and no video,but full motor function.... hmmmmmm. I just don't know. I'm not afraid to try a REBIND of radio and camera but maybe you might know what the issue is. I am not new to flying and Yuneec is all I fly and I love my Typhoon H as well as my Typhoon Q500 4K's!!! Sorry for the length but I wanted to be as thorough as possible. Thanks everyone!!
