I had the same thing happen when I suddenly lost video and flight control at what should have been a safe distance out. The ST16 was still ON but had switched to the Systems Settings screen. I engaged the RTH switch. The TH flew back to me at the preset RTH height and started descending. When I finally figured out that I needed to return to the flight control screen, I was able to manually land safely, but still no video. Rebooted TH and ST16, everything back to normal. The fault had occurred while I was adjusting the white balance during the flight. That might have been a coincidence but it didn't feel that way. There's actually a 3-1/2 minute gap in the telemetry file while it was returning to overhead!
Are you saying you are infallible and could not have possibly bumped a button with a finger or knuckle while adjusting W/B? FYI, that's exactly what I was doing when I put mine in Pad mode. The part people leave out is where they tapped the yes button before the screen went to another mode...
I should mention that I did this before I had become familiar with the ST-16, and pushed yes to accept the mode change without realizing what I was accepting, and was totally unaware that I had accidentally pressed the Pad button when adjusting the camera. I doubt I have been the only one to make that mistake.
