Hi, my neighbor gave me a faulty bike headlamp (Magicshine MJ-906B) and asked if I could have a look at it. I opened it up and saw a blown-up component, likely some kind of transistor. The writing on the component looks like "AG5V" but I can´t seem to find any information on this component. Does anyone know what it could be? Also it seems that someone else had worked on the device before (the battery wire soldering looks bad) but since it worked until recently that´s probably unrelated... Any help would be appreciated....
