Bamboo gtx need help

So I lost my charger an I went to Walmart an got a multi plug charger and it was not plugged into the wall at all I was just checking to see what head would fit and i plugged the first head in an a big spark and the green lights on charger box lit up pulled it out right away but now that I got the right charger the board won't light up or turn on. Is there a fuse or anything or what do I do I'm so mad at my self right now
