He said that it worked when he put it in there, but now, the screen will light up, but nothing else. Hi, I just came across a Jr Pac-man that was sitting in this guy’s garage. Since ur screen is scrambled that is what’s coming to the monitor from the pcb daughter cards and eproms etc.so more than likely without being able to see ur game I’d say the problem is board or vram related….u might want to check everything going to ur monitor from ur boards including ur pcb connector.id replace the old connector with a pac to jamma connector and a new 15amp power supply too.in case there’s a bad connection or a short somewhere there…replace until working that’s all I know to do…when u check it look for shorts.bad or burnt places or pins bent dirty or broken Ok if a new board didn’t help then u can rule out the pcb.unless u used the same vram or daughter board.if so check to make sure a pin hasn’t been folded up underneath on the vram to the pcb or daughter card…or start replacing boards : u said u already bought a new pcb did it come with all boards installed…in other words.think in terms of status: what have I replaced new and why is it still doing the same thing.what is left on from the old. Looking for hard to find Pac/Ms Pac parts for your game? Click here for our Parts for Repair Page If you have a Cocktail table game then proceed to the Pacman Cocktail Table Repair Post First. Then Please Proceed to the Step Two Post: Blank Screen Repair. With All that being said, let’s jump right into it! Take a moment to review the picture below to get familiar with your Pacman Machine. Please read our disclaimer in the footer below before beginning. Pacman will be the sole focus moving forward. So you may be able to diagnose your problems through this site for a similar type game, but Pacman or Ms. Basically an arcade machine consists of a power supply, monitor, a PCB, and controls. In many cases the following steps can be used to diagnose or repair other arcade games of the era, so if you have other arcade game models besides Pacman then in many cases the problems will be common to all. So follow each step and we’ll get you to the root of the problem as fast as we can. I have purposely written each post in an easy to follow hopefully non-technical way so that even a novice can understand. So again please follow these steps as directed to correctly diagnose the problems and don’t assume it’s one thing or the other until each has been ruled out or you’re ask to move on to the next step. Note: You may think you already know what the problem with your Pacman is, for example you may think you have a bad monitor when in fact it could really just be a simple blown fuse or a power supply problem or you may even perceive you have a Printed Circuit Board (PCB) issue, but what you could actually have is a wiring problem or an Eprom issue etc. I’m also assuming of course that the entire Pacman or Ms Pacman game is complete and has the original PCBs, monitor, power supply…etc which is all hooked up right and was working at one time, but now it is not. All other Pacman variations or newer MAME type games, multicades, or other computer games are not meant to be diagnosed through this site. Note: These instructions are intended to diagnose only the problems of an original coin-op Pacman or Ms Pacman stand up and/or an original Pacman or Ms Pac Cocktail Table Machine or Original Mini. If the instructions call for you to plug the game back in to test it, then please don’t touch any of the electrical parts inside– basically please use common sense and use your eyes instead of your hands while the game is plugged in or turned On. Always UNPLUG your machine while you are working on it.
