I'm going to guess that some water got in it and caused a short. The line you see with the white stuff on it (from the rubber mat with the buttons) melted right on the line. That line was completely shorted. I scratched it a lot and cleaned it and tested with multimeter - still shorted with ground. Had to bypass it all with isolated wire that I used from a macbook air lcd cable. Same thing on the other side (which connects to that line)
