Do all three calibrations, IMU, compass, and gimbal. Cross your fingers, fire 'er up, and hope for the best! If nothing looks to be outwardly broken, the internals are surprisingly robust.
I have done all three. Nada. Thank You for the reply. How would I know if I need to replace the ribbon. It seems that the gimbal ( other than having video ) has no power.
The gimbal moves completely free in all directions. It appears normal. Clear video from the camera. If I position the camera downward it returns back to its default position. Like I said it’s as if it just lost power.
