@Chuck sorry for the slow reply here, but glad we got a chance to catch up over the phone.

Note: for a v1 Polycade, repairing this issue may involve opening the cabinet since the button panel on the v1 is not easily removable. You can see an example of opening the v1 cabinet in this user created video.
