    My game did the same thing, but is 'new' from a factory in California and not from the 80s. I do not know the make of the monitor (a lot of things are in Chinese). I was sent and replaced the entire monitor chassis (the big board behind the monitor, suction cup thing, all of it), but still, the same thing is happening. Power on, games working, but screen is black.

I'm assuming this game cabinet was built in the 80's. More than likely, the monitor is an Electrohome GO-7. If this is the case, replace capacitor C511 on the monitor board. It has baked open due to old age. Usually, capacitor kits can be purchased for around 10 bucks, so you might want to replace all the caps on the board at ths time. Worst case scenario would be that the Flyback transformer has smoked (usually you'll see a crack on the side of the transformer), causing the horizontal output transistor to cook and also the smaller of the two pigtail fuses to blow. In this case, you would have to replace the Flyback transformer, the horizontal output transistor, and the small pigtail fuse associated with it. Remember to always discharge the second anode( the suction cup thingy on the side of the tube). It will hold a substantial charge on it. Also, if the small pigtail fuse is blown, you will need to discharge the large cap on the monitor board, or else it will knock you on your rear-end when you try to replace the blown fuse. Hopefully, you'll will only have to replace one cap. C511. If your game does not have an electrohome monitor, I can still help, if you provide the manufacturers info, such as Well Gardner model 7204, or something like that. Good luck!

The sound loads, but no picture at all. I have an original 1981 cocktail Galaga game.


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.

How do I hook up the plut it in & play retro arcade Pac-Man game? It's the little $25 dollar game system. It appears very simple, but I must be doing something wrong.


Are you talking about the little new thing you connect to a TV? That should be easy. Video plug to video input, and audio to audio :)
If you don't have video and audio inputs on your TV , you woll need to get a video modulator.

Let us know.

Upright Ms. Pacman video game has really small screen?


if you're good at soldering, you can replace a few things on the monitor's main board. puffy capacitors (look like cans) especially. but before you do so, you'll need to discharge the crt tube by running the stored charge (up to 20,000 volts dc) straight to a ground source. it's a big deal and it's dangerous if done incorrectly, so you might want to leave it to the professionals. now might be a good time to change to a lcd monitor.

PACMAN GALAGA COCKTAIL TABLE


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.
