After a crash, the propellers spin up, led lights work, and the wifi signal to the DJI app work fine. However after I power on the battery there is no blinking indicator light on the gimbal and there is no movement of the gimbal motors at all. It is like it is dead. I have taken everything apart to inspect for damage. What I noticed is that the swing arm is stuck and looks like it pressed up into the pcb a little. Does slight damage to the pcb cause a loss in power? I did not notice any obvious rips or tears in the ribbon cable. I will find a separate stand alone power source to run the gimbal this weekend to help trace the problem. Any other advice out there on how to trouble shoot this loss in power?
