Had a relatively minor hard landing and severed part of the PTZ cable. Got the parts in and repaired the drone, which basically involves disassembly of a large part of the body and nearly every screw removed from the gimbal. As of now, there are two disassembly videos on YouTube. One from Cambodia and one from China (that I just discovered but haven't watched.)
I was mostly successful in repairing the drone, but after start up, it positions the camera facing back into the drone and won't calibrate....most of the time. There have been four instances of me fiddling with the camera, and suddenly it snaps into the correct position and will allow me to calibrate to 100%. It then shows no error codes and seems fixed. But as soon as i power the drone off then back on, it has lost calibration and will point the camera back towards the drone again, followed by four gimbal related error codes.
What sucks is that I really can't test it accurately unless I put it all back together. So when it doesn't work, I have to take it all back apart and try another tweak. And that's really starting to wear my patience thin.
I'm currently in the process of trying different positions of lining up the three screw holes of the gimbal motors with the camera housing. Since they are equidistant from each other, I'm hopeful that if I change the housing position in relation to the motors, eventually I will find the correct alignment and it will point the camera outwards and will allow calibration.
Please comment if you have repaired your mavic 4 and have run into this issue. It's extremely annoying to know I'm 99% there but just can't seem to find that one tiny thing that's not right.
Side note: I reached out to DJI to try and speak to a technician that has worked on the mavic 4 and they basically told me to get bent. In a really nice way, of course...but still not helpful at all.
