Hi,

I have the gl-3x gimbal and the board is different, but i have the same problem with the yaw motor: it doesn't start and it warms up; if I touch the behind of the board, in the part of circuit that drives the the yaw motor, it makes a strange sound and the motor tries to start.
What could it be?
This is the type of board I'm using (in the photo are specified the pins of the yaw motor).
Thanks.

I hope someone can give us some tips to solve this problem.
Many people with this gimbal have same problem but I couldn't find any solution.
