So I finally had my first real crash with my p3 Pro. And it was a doozy. Busted gimbal arms. Ripped ribbon cable. Drone still flys perfect regardless. So I bought the replacement ribbon and gimbal arm kit. Mid repair I try to connect JUST the ribbon cable from my camera lens to the gimbal board. Power it up.. Nothing but black from display. No picture. Is this a bad sign?,,,, Or does all the gimbal motors have to be hooked up to get it all cooperating. I still need one of the gimbal pieces for full rebuild but I find myself wondering if I should just stop and buy a whole new camera, which is stupid expensive. I have seen phantom 3 standard new for the price of just the camera/gimbal of the pro version. What would be my next troubleshooting step to see if the gimbal board is working. no obvious damage was done to the board.
