Quoted from goldant:Turns out the problem was a micro usb cable that had come unplugged from the central circuit board with all of the grey led cables going into (go figure). It was hanging 3/4 of the way and I had missed it since I was focusing on tracing all of the colorful cables and not the plain black cable.
Thanks for your help LTG and Pinballinreno
Same thing happened to me a week or so ago. Easy fix.
