i have a controller circuit board taken from one of those new 2 wheel self balancing boards. it was all working fine and then stopped working, i removed the main controller circuit board and discover a blown transistor i replaced this with the exact same component reconnected the battery and it caused a capacitor to blow i replaced this with the exact same component and connected the battery and the transistor blew, i have tried replacing them both a few times same result every time somtimes both will blow, i have attached a picture of the board if anybody has any ideas i could try it would be much appreciated. thanks in advance.
