Screen over top of each other
Question from Carl: Hi, any help would be great. I’m building a machine using a Game Elf and JAMMA harness inside a Naomi cab with a CRT monitor. I can’t seem to get a single screen, just this one over top of each other. Carl from UK

Response from Jonathan: Carl,
It looks like you may need to adjust the horizontal and/or vertical hold potentiometers (or pots) on your monitor chassis. It’s common to experience problems like this when you swap boards in a JAMMA wired cabinet. Check out our post on Adjusting An Arcade Monitor for more information. Please let us know if the problem continues after trying the adjustments and we’ll try to help you out further with your issue.
Hope that helps. Thank you for your question and good luck with your repair.
