My Phantom 3 Profess. has this error code displayed on the camera view in the App.

"No Image Transmission Signal"

Any ideas?

Im getting the same thing after fw update

Same thing here. Resulted in hard landing this morning. Now I can't get my bird up in the air. Have taken everything apart to make sure no loose connections but no explanation. I still have video feed, despite the message, but have zero satellite connections and no battery info (plus it won't fire up the motors, giving a timeout error).
