Let me maybe just ask where can one find out error codes on the ph4 pro. I repaired the gimbal and flex cable,as well as yaw, pitch, and toll motors. Now after powering on the aircraft I hear beep.... beep... every second. The light on the gimbal starts to flash 2 or 3 times quickly red, and inside the aircraft I see by a vision sensor a red light. gimbal to me just not seemingly correct but even with no gimbal attached I get the same issue.
