Had a gimbal cable break and ultimately replaced the camera and gimbal assembly with a new set (less than $100 and ready to go). Problem I've got is that the camera focus is about 3+ inches in front of the lens and I can't get it to adjust. Did the gimbal calibration, IMU calibration, tried manual , and have tapped the screen in the green screen box, and tried pressing switch C1 (or C2). Nothing worked. The gimbal operation seems perfect and no other anomalies come up. I have a new camera module that I'm tempted to try replacing but am not sure just where the focus mechanism is. Anybody familiar with this who has been able to resolve it short of sending it off for someone else to fix?
