This monitor was never working right when I got this project. I only see 5 wires coming into the connector (the purple one temporarily connected to pin 1 is coming off the V Sync on the JAMMA connector.
Should there be an H Sync wire plugged into this header pin? I'm confused. I also get mixed comments on which pin the sync wire should be on. Some say pin 1 at the end, but the board shows V Sync next to the ground wire.
Someone wrote WG 25k7401 on the top of the chassis frame, so I assume that's what the monitor is.
