No Image Transmission Signal - cycle on and off

[Chook]

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?

Problem solved. Once I refreshed the firmware it cleared up the problem. My issue was that I could not update/refresh the firmware because of some issue with the MicroSD card that I was using. When I went back to the original one included with the Phantom 4 the option to refresh the firmware was available in dji assistant 2. Once refreshed it now all appears to be normal. (I did use the problem MicroSD card in another device).
