My Wiiu gamepad is not working, the charge led does not lights up, I've opened it and I found some dirt next to U10, after cleaning it, it seems like this four traces got shorted and burned itself, the visible part of the traces goes to unpopulated resistor/capacitor pads, while the vias seems it's going to inner layers of the board, is it possible to determine where they go and put jumper wires on it ? Is there a service manual or board schematic to follow ?
