I have a 193-in-1 multi board and when I test it it has the vertical hold is all screwed up - its just a bunch of colored lines flipping through the screen

- i can't find the dip-switch settings thought it might be a video dip switch - im running it through a standard vintage 19" arcade monitor in an old cocktail cabinet. I tested all the dip switches on and off and it didn't seem to help - I tested a few other PCB's on the same cabinet and they work fine.

any suggestions?
 
You need to tell us the exact model of the monitor. Certain monitors will require different sync wiring for different boards...
