Hi I upgraded my mp40 wes with a qd controller in October. I upgraded two actually. One of them yesterday just stopped working and won't light up at all. The power brick has the green light on nut no power to the controller. Any help on how to fix this would be great

I would recommend connecting your known good power supply to this controller and try to isolate the issue to the power supply or controller. Once you've determined the cause of the failure, please contact our customer service department.
