Cocktail Ms Pacman Table
Cocktail Ms Pacman Tab  

Bottom of monitor
Bottom of monitor  
We have sound but monitor not lighting. Unplugged & unbuckled the top & layer it open, then turned back on. After waiting a few the Screen initialized & lights up beautifully. However, when we close the top to a certain point (about 3/4 of the way), the monitor shuts down but not the sound. Is there a magnetic part maybe causing this shutdown? HELP? I can send more photos if you need?

Answer
Hi Mick,

It looks like you have one of the monitors in that game that is notorious for what is called "cold solder joints".

Those two boards that are perpendicular to the main chassis on the monitor are usually the main culprits. When you have the top open, they are making a good connection- when it's closed, they lose connection. Try to gently unplug and the replug each of those boards with the power off. Just redoing those connectors might help, but you'll likely want to pull the monitor chassis board and reflow the solder on the bottoms of these.

If you choose to do that, please be sure that you are qualified to, as the monitor will hold around a 20,000 volt charge, which can be fatal.

Hope this helps!
Brian

Expertise

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.

Experience

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.
