Hello all! I have a Neo Geo Converstion that I have been working on for ages. First the monitor had problems which cost $125 to fix, now it appears as if the Sync on the PCB board may be bad.. does anyone(particularly in the Denver Metro Area) have a Jamma board I can borrow or even buy cheap so I can test this monitor and see if the repair actually worked?
Thanks everyone!

Before you go too far...
Try switching the sync wires around. Some monitors, esp. the older ones, only need 1 of the 2 syncs, and others like the syncs tied together. I would experiment. Also, I am assuming its a fairly new monitor, but.....
Make sure there is not a switch for positive or negative sync. I have seen those be culprit before...

I tried that.. it didn't work. I really hope its not the board.. paid alot for it. Its like the sync isn't doing anything.. the picture on the monitor doesn't change at all regardless of if its plugged in or not
