I'm a new pilot and this is my first post. I purchased a Phantom 4 exactly one month ago and today I'm having a problem with it. After powering up I get the status "No Image Transmission Signal", it then changes to "Safe to Fly" briefly (and I get a camera image), it then goes back to the "No Image Transmission Signal" and cycles through these two message for a while before it end on the "No Image.." message. I also note that the Gimbal Status is "Gimbal Disconnected". I've tried updating firmware but I get a "failed" message. Any ideas?
