I am receiving the above code on Mavic 2.
Anyone know how to clear it as it is stopping me from flying?

Good news. I’ve just removed my microSD card from my drone and this has cleared the error.

Hi. I am sorry for the trouble that this has caused you before and thank you for giving us an update. It is great to know that the issue has been resolved. Just in case this issue will again happened ( error code 200 ). Please try to perform the following troubleshooting steps. First, re-insert the USB cable of the remote controller, second, remove USB cable and SD card, and finally restart the said drone. If the issue still persists after this process, kindly please contact our DJI support team to start up a ticket for the said drone at https://www.dji.com/support?site=brandsite&from=nav . Thank you.

Hello everybody.
I have found the solution to error code 200.
The video signal is transmitted by a cable with 30 very thin wires.
Well ... you need to take apart the drone, the gimball and check that there are no broken wires in the cable.
If the wires are intact, there is most likely a short circuit between the wires that have a thin layer of insulating varnish.
This insulator deteriorates over time and during use, leaving copper wires exposed.
The solution is to spray a thin layer of spray paint between the threads. I leave some photos to better understand the problem.
