Video Game Repair/Ms. Pac Man


Hi Brian,

I have an upright Ms. Pac Man arcade game that was working fine until it was moved.  Screen is fine, but there's no sound and the machine just keeps running in demo mode...Start game & One or Two Players buttons don't work.


Sorry for the brevity of this answer, but open the control panel and disconnect the pic plug and then plug it back in. Is are that you have a bad ground connection. If that doesn't work, look at the wires on each of the buttons. The ground is chained, so one bad wire will stop all of it from working.

I can answer questions regarding coin-operated arcade game questions down to the logic board. Error codes, erratic operation, dead boards, I can help with them all. I can help with video monitors on a very limited and basic level only.


I have spent nearly 20 years as an avid arcade collector, and spent nearly 10 of those years as the lead tech for a large arcade operator, doing work for manufacturers and other coin-operated amusement companies around the globe. I maintain a good sized collection of arcade games, as well as a large inventory of spare parts for a wide range of arcade machines.
