Hi,
BSOD usually means long screw trace damage, this is when the screws by the LCD connector shield are mixed up and put in the wrong place, it basically causes damage to the tiny traces in the logic board because the screw is too long and digs in to the logic board.
You could also try unplugging the front facing camera flex and charging port to see if it solves your issue, if not, it is more than likely trace damage, which you would need to know how to microsolder. :-)
