Hello Gents,
I currently own a Super Pac-Man, completely original. All wiring and boards are original. Everything looks to be in pretty good shape. Everything was working perfectly as should. Until I purchased a new power cord and high save score kit. The parts were ordered from The arcade shop. The parts arrived quick and packaged nicely. I began to install the parts. The power cord was easy. Just unclipped the old one and installed the new one. I then disconnected the harnesses from the cpu pcb and the video pcb. I removed the chips as indicated on Steven's website. 1b and 1c from the cpu board and the ram from the video pcb. I replaced the boards, connected the harnesses back up and Upon plugging the game in and turning it on, the lights came on the monitor displayed some scrabbled lines then went black. I have no sound, no monitor, but I have power to the lights.
Now, I have an email to Steven from the arcade shop. I have not heard back from him yet. It's around the holiday and I'm sure he is busy. I'm sure he will get back to me soon. I figured I would post my problems here to get some more input.
I have checked all my wire harness connections. The chips appear to be seated properly on the boards. I'm new to this hobby so I'm not sure if it matters which way the chips are installed. Looks like they can be installed two ways. I checked all fuses by eye and they appear to be good. (I need to check them all with a multi-meter). I'm not sure if it matters but I did also notice that the power cord steven sent me is wired up a little different. The harness connector is the same but the black and white wires to it are switched. Any help would be greatly appreciated. Thanks!
