Hey guys, just acquired a PM last week. It has the OCD board installed with LEDs. Here are my issues:
1. Two of the lights are permanently on (Miraculous Save and Power change). They flicker but never turn off completely.
2. Shaman lights flicker and stay on sometimes when they aren't supposed to.
3. Encore light stays on and flickers during game play, but not in attract mode.
I have controlled the OCD board with a computer, and dimming the lights with the board settings does not seem to help.
I have checked the double matrix in hopes of finding some sort of pattern. I can't seem to find a correlation with the exception that Miraculous Save and Power change are in the same row, if I remember. However, the other lights in that row do not have this issue.
I have tested and replaced a few diodes where I thought the problem might be coming from, but the diodes tested fine out of circuit. I'm assuming that because rows and columns have lamps that are functioning properly, it is not a transistor on the driver board. That being said, there are transistors on the OCD board, and I have no idea how that board works.
Any help would be greatly appreciated. I'm completely new to Capcom and the OCD board.
