So took the board out again for an inspection. No signs or marcs of arcing to the metal chassis frame so maybe its just arcing on the socket pins. There was some flux
left on the pins from a flux pen I used so I cleaned that off good, and cleaned and defluxed the board some more but after reinstalling, still have the arcing. Someone else suggested
to check the switch foil pads for cracks, as they crack easily. I guess will have to take the board out once again.
