SNK Neo Geo CD Controller Input Repair Part 1

A short video showing the repair and testing of a Neo Geo CD control input PCB for Console Snob. I didn’t have the full console, just the control PCB.

Update 23/05 – Scott the board back but sadly the up direction on both ports is still not working. This means there’s either a fault on the motherboard, or I’ve missed something whilst testing. Perhaps an input is being pulled high by the motherboard, or when connected a fault in one of the neo buf chips becomes apparent.
