This Mr Do (in an Asteroids cabinet) is in for a monitor rebuild and PCB clean and check.
Update: Monitor has been cleaned and is out for chassis rebuild. Monitor is back and looks great after the rebuild. PCB sockets, chips, and edge connectors have been cleaned.
The PCB is showing double images on the characters, which is a logic issue. The board has been sent to Classic Arcade Repair for repair (10 to 12 weeks until we get it back).
