well, the banquet hall I had my wedding at last month asked me to fix their Pac-Man, which originally had a monitor that wouldn't turn on. upon inspection whatever it shipped with was replaced by a K7200 (I forget which exact model it was)
after I tore the whole game apart I found that there was a loose pin in the AC connector and sure enough, the monitor fired up. however in the process of pulling the monitor, like a dipshit I forgot to unplug the signal connectors and broke a wire off on the sync connector.
I assumed fixing the sync issue would be as simple as crimping a new pin on and sliding it in, but I still have no sync.
I'm not knowledgeable about Pac-Man, this is my first time putzing with one of them, but according to the pinout there's only a single sync wire, but on the other side I have 3 orange/red wires that plug there... so does it run on negative composite sync or is it positive or what's the deal?
Wells doesn't have a manual posted for the K7200 so I went off the K7000 one for the header pinouts and this thing was wired to the negatives on both the -H and -V.
the people I've talked to about it have no knowledge of the game's operation state before the monitor not turning on issue arose, so I can't tell if it worked this way before or not.
I played with both the H-Hold and V-Hold pots to no avail, this thing just has no sync. wiggling the edge connector wires resulted in what appeared to be primary colors going in and out, which I could tell from the red disappearing from the scrambled mess.
so anyone out there just tell me what it'll take to make it work on a K7200.
thanks.
