Hi everyone,
I faced with strange problem never described here:
The symptoms:
  - No SD card message after boot up
  - Blurry video feed from camera (focus, gimbal control etc. doesn't work)
  - Gimbal status - N\A
  - Camera (video feed) time to time reboots
  - Sometimes getting "Encoder error 0x80000"
The issue exists only when mavic are cold, that means  internal fan does not work and lower part of the body is not warm on touch.
It is self fix when mavic body temperature are high  enough. I tested this by warming up it by hairdryer before power on.
I seems like HW issue with motherboard

Any suggestions please?

Full replacement of motherboard =(

that was the definitive solution? same issue here.

If ya fly in low temperature then hold the AC warmed in bag or backpack. 15°C of bodytemperature should be enough.

i already solved the problem in my case, I reinstalled the last update from the computer with the dji assistant 2 and now is working like new

Hello, did you solve the problem? I have the same problem when mavic is cold.
