There's a loose connection somewhere in one of my dance mats; the pads are registering (LEDs lighting up), but the message isn't getting to the PS2. We've taken it apart but the connections to the PCB look fine -- so either the problem is on the PCB (surely not?) or in the cable. Should I just admit defeat and buy new ones? Or I could cannibalise a different PS controller and solder the wires onto the PCB... if the wires are standard colours? Anyone have any experience in this sort of thing?
