During Galaga the fire button stops working - Arcade Ms Pac Man / Galaga Cocktail Table Video Game

I had a tumble dryer that stopped working and after much investigation it turned out to be an internal thermostatic switch and lots of fluff around the internal filters. ( Mine had 2 of them 1 would cut the heat and kick back in when the temperature dropped and the other one would completely cut all power rendering the drier non usable until cicuit breaker thermostat was replaced. The reason they cut out is to prevent overheating and possible fire. When the thermostat gets to certain temperature it breaks the circuit. Apparently you shouldn't stop the drier until it has completely cooled down as there will be too much heat which could cause a fire, which is why most drier cycles have 10 minutes of cool/ non heated air at the end. So in conclusion I would take all the filters out and give them a good clean and try to avoid opening the door while there is still a lot of heat in the drier. I'm not sure if this will help but its a starting point.

Hello: You want replace it for a 4 position or 8 position
4 position work better for some old games

Hello: first thing is check the 5V+ 12V+ -5V in the power
supply, sometimes when the power supply goes low or
high cause that problem, other thing that you need check
is the connector for the logic, sometimes contacts get
black, use a eraser to clean the contacts, the last thing
is reseat all chips in the logic, the ones that are in sockets
Thank You..

1.Check the dip switches for cocktail set up/ no upright.
2.does the screen flip to the player 2? if yes
3.make sure you have good dc ground in player 2 joystick.
4.if no picture flip for player 2, go to solution 1.
Thank You.

HI Kristen,

IF you can "play" the game blind, that shows the game board is working fine.
The issue can be in the monitor. That can be many reasons there is no picture .Check all plugs and connectors. Make sure the back of the CT is plugged in. Power to the monitor is present. Do you have amanual for the arcade? You should be able to find one online.

Do you see the picture tube lit up, not on the screen, but in the back of the neck of the tube? (Orange glow from the filament)

I"d suggest that you seek out a qualified service person for the game, if you are not familiar with working on electronics.

There are fuses in the cabinet power supply I believe, check those. Could be something as simple as the fuse going to the monitor.

Nice machine, hope you get it going.

Look up your local coin op amusements vendors that provide equipment to local bars etc, They may be helpfull as they deal in these repairs everyday.

ok 24 v at the transformer is yes than a safety swicth turn the heater off check fuses

there are buttons inside the coin door for programming. one button will bring you to programming mode on the screen and use the other(s) for selections. you can put it on free mode.

your monitor high voltage circuit has failed troubleshoot it as any tv

Use the joystick controller's right and left to select options, and then use either one of the buttons to make your selection. The button with 1 human stick figure next to it is the Player 1 button, and the one with two stick figures is the Player 2 button. Unless the defaults were changed on that machine, 1 quarter is required for 1 player and 2 quarters are required for two players. I haven't used one of these machines since the original from 1982 to 1986. I can't believe it, but Namco actually has put a PDF of the service manual for this unit on their website:

Have fun! I would love to have one of these on day.
