Hello guys ,i have a problem with my flipsky 75200 pro controller and I'm hoping maybe some of you experienced people can give some good advice on what to do next. I was waiting on the green light on my electric scooter when the controller suddenly died. It does not power on and the blue light does not turn on. When plugged into the battery pack it makes a small buzzing sound which stops 2 seconds after the battery pack is unplugged. Here is a video of the buzzing sound when connected to the battery and it stopping after disconnecting the battery.

Look carefully the base of the capacitor on the ground side; might be one blown. I think it's related to a hardware flaw... mine is brand new and had work for 20 min.
