Mini 3 Camera & Downward Vision Error

[aaronh543]

Hello,
I recently crashed my Mini 3 into a river and after drying I got an error indicating the ESC was damaged. I replaced the ESC board, which I believe solved the motor issue as they now move on startup like normal. But now I'm getting errors for my downward vision sensor 180016 & 180017, forward vision sensor 180018, gimbal IMU data error 40021, camera malfunction 10001. Has anyone had anything like this happen? Maybe some solder splatter from installing the new ESC? I have another Mini 3 on order but would really love to get this back running so I have a backup. Thanks for any suggestions.

Solder splatter?!
The cable that connects the sensor to the main board is faulty....180017 examine everything closely and replace it if you don't see any bad connections
the 40021 Error is a part mismatch and something needs to be matched or serialized. (IMU?)
the 10001 error could be a result of the other errors BUT typically means the camera needs replacing.
If you are making "solder Splatter" your doing it wrong! soldering irons are not made for melting solder!

I repaired a clients Air 2S not long ago, it had crashed on dry land, as a result the body and one arm where broken and the forward sensor was not working. I replaced the sensor and the body parts and the unit is now flying again. You can check the sensors by running the DJI alignment software program I used DJI assistant 2 available on the DJI website.. Good Luck
