Hi, I'm currently having issues with all of my control panel buttons/joystick. Nothing works. I have re grounded my cabinet checked voltage/grounding/continuity/Pin wear/clean. Looks good
Should my PSU be grounded back to my mains or is that done internally? Also how does my jamma pins get grounded back? I'm assuming everything is internal in the psu and my pcb is the actual issue. Any input is appreciated.

Connector with Jamma Nation X Atlus v1.4
