DJI FPV RC signal lost after crash/repair

[GTomi]

Hi everyone,
I crashed my DJI FPV drone.

• Left front arm – replaced
• Right rear arm – replaced
• Camera – replaced
• IMU – replaced

After reassembling it, I see the following messages in the goggles:

• "RC signal lost"
• "Airsense communication error"

The Airsense is not damaged.
The camera feed does not appear in the goggles, and there is no communication with the drone.
Could you help me troubleshoot the issue? Could something else be damaged?

Thank you!

Just link everything again, long press on the battery button until it beeps, same on RC, then battery again and goggles bind button. Refer to manual.

Hi, Thanks for the reply.
In the meantime, I was searching the internet and found a suggestion to recalibrate the IMU.
I entered the safety menu, and the IMU status was normal.
I recalibrated the IMU. It slowly went up to 4%, and then it exited to the main menu.
Now, the IMU error status is also displayed.
Is there a connection between the IMU, the camera feed, and the AirSense function?

Well everything is handled by the mainboard, so it looks like something got damaged.

Is there a service program that tests the drone and tells you what is wrong?

Not that I know of outside of DJI service centers. Will likely need a trip to DJI repair.
