I bought a crashed drone online to refurbish and sell as I do quite often. It needed a front left arm replacement “no problem”
It only had a cannot take off error due to the arm.
I professionally replaced the front left arm. when soldering I made sure to do it very quickly to not heat up the ESC board.
I put it back together gently.
When booting it back up, I was encountered with multiple gimbal errors
* Gimbal stuck. Make sure gimbal cover is removed and
* manually check whether gimbal can rotate freely (Code:⏎[br]
1d010002)⏎[br]
Gimbal error. Restart aircraft (Code: 1dOc0003;⏎[br]
1dOc0004; 1d0e0001
Nothing was done to the gimbal during the repair, but I went through the gimbal took it apart tested the PTZ coax cable, it tested fine. Checked the gimbal motors. Even doing a DJI factory test by wiggling parts of the wire and physically inspected lines, all good
When booting the drone back up for the first 5 to 10 seconds the gimbal seems fine. Then suddenly goes limp and is unresponsive. I rebooted and tried again and then it seemed fine. Then I rebooted again and it went back to being limp after a few seconds.
I did a IMU compass Calibration. Updated the firmware refreshed the firmware. Factory reset the drone. When trying to calibrate using DJI assistant, it stops at 10%. Physical inspection shows everything is fine the buckles, the connectors, the boards don’t seem to have any burn marks. Check for resistance on the gimbal motors. Everything seems in order.
What can I do next?
