I had a hard landing with the DJI Inspire 2. There in no physical damage to the drone, but I'm receiving two errors. Is there a diagnostic or maintenance I can perform before moving to seen the drone off for repair?

Errors:
- ESC No. 4 Error
- Camera Sensor Error

Have you tried going through all the different calibrations?

Hi Robert, for ESC error, you may try to restart the drone or refresh the firmware for the aircraft.
For the camera sensor error, please try to remove the gimbal, clean the connectors on the gimbal and aircraft and try again.
If the issue persists, or the errors only pop up after the hard landing, I'd suggest sending the drone back for diagnosis and service.
Please fill out the online repair request on our official web and then send it back. Here is the link: https://repair.dji.com/repair/index
