Hello guys,I have a metal servo motor sitting in my room,and it is not working.It all happened when I was experimenting it with arduino,and all of a sudden it stopped working.Can you please help me to repair it,any suggestions would be helpful.

First power the motor inside directly from a 1s lipo after opening the case. Should it rotate, change the board with any 9g board after checking the connections. Should the motor not spin check its brush. pm or wp me for any help 8013074701
