Help! My flight controller not working properly

[JackNZ]

I got myself a new Mateksys F504 mini for my new 3 inch frame and it worked great I put around 8-10 batterys through it and then after a crash motor 4 didn't work.
I tried plugging the signal wire from motor 4 into motor 3 and the motor worked so its not the ESC or the motor.
I have connected the flight controller to my sillyscope.

The bottom is motor 4 and the top is another motor. Does anyone know how to fix it.

Looks like you may have physically damaged the motor 4 circuitry. Luckily that board has 6 motor outputs, so you should be able to remap one of your extras to motor 4.
