Hello dear fellows.

I recently changed my FPV DJI drone one of the front arms,  however after putting everything back together, when I turned on the drone, the gimbal went crazy up and down, and no image in my googles.  Not sure what went wrong.  Not sure what to do next. Any reccomendation?  Thank you all!
