MAVIC 2 ZOOM Cannot Fly after Crash

[epulo]

I have Mavic 2 zoom crash, and it is damage only at Antenna but connection and camera still function well, also the rotor still able to rotate. once trying to fly again after cleaning, the drone only able to airborne about 0,7 Feet and there is popup warning "Upward obstacle sensor detected/activated", check for the error its written : "Infrared sensor error, hardware malfunction. Contact DJI for arrange the repair". the upward sensor there is no damage sign and block by something. first suspect is upward and downward infrared sensor as it cannot be calibrate at DJI assistance, i decided to replace both sensor board, but the error won't disappear. second suspect is mainboard, but before replace i would to seek some advice here, probably got same experience and could found the main item is broken. thank you

Hi all, i have found the solution, but still unable to explain in theoretical. After change the sensor upward and downward, still pop up the error
Message , “infrared sensor error...”, after try to change the remote, the message is dissapear, and able to fly normally. Return to old remote, the problem occur again. Try to check the remote and refresh the program, found error and unable to refresh . Still wondering why, drone crash but remote effected. Thats the update to those who have similar issue. Image below before after, other remote ok, original remote shows error
