I’m glad I found your site. It has been very helpful so far. I am the neighborhood fix it guy. A neighbor brought me his Ms Pac-Man upright machine. It is not “playing”. There is power to the monitor, PCB, lights, and coin door. 5VDC and 12VDC check out. No blown fuses. There is a whining sound coming from the speaker at power up. The monitor is full of small orange dots. No discernible image.
I read through your entire site. It seems like the original PCB has been replaced with a new smaller PCB. There is a green LED on the board that is lit. So it’s getting power. I don’t get any response from the machine when I press any buttons, or simulate coins being dropped in by pressing the micro switch levers.
Do you have any other areas I can check?
Yes Sounds like a chip Eprom problem . The legs of the Eproms are not connecting or shorted or simply out of socket …Goto the eprom section of this site to see how to unseat the chips and clean them
Thanks for the quick reply. I checked the board again. This looks like a board I saw on eBay when I was researching this machine. It’s the only board in the machine and it’s 6 inches by 6 inches. According to information I found on your site the board has a JAMMA connector. There is also an empty VGA socket on the board, as well as, a socket that looks like an external power adapter socket. There is also a socket that looks like a PC power supply socket with 4 pins in it. None of these are used. Only the JAMMA connector is connected. There is no EPROM chip in a socket. All of these components are surface mount. It looks like an Altera processor? From what I saw on eBay, this might be one of those 30 in 1 game boards. My guess now, is that this whole board is bad.
Yes quicker just to replace with a new 60-1 board or jamma pac board
