Jamma 60-1 video?

If you like, you could bring the board over and test it on my little test stand.

You have to change a dipswitch on the board to change from arcade to pc monitor...was it originally connected to the VGA out or the arcade out?

Well tried 4 different PC monitors all different makes... All same results... Tried both ways Dip #2 on/off.. Turned machine off changing monitors, changed dip switch then turning everything back on...

I bet the monitor In your cabinet is a 4900 I had that problem it ended up being a cold solder joint somewhere cant remember where tho

Check your power supply voltages, too. Perhaps an improper voltage is keeping the board from working properly. +5 should be no higher than 5.20...

Changed to board and all seems to be back to normal so far!!

Thanks for all the help!!!

60-in-1 centering problem

I have done many 60-in-1 games and I have a question. I use Dell Ultrasharps, usually 1908fps or 1907fps or similar. A lot of times after hooking up the system, the screen is not centered. I will usually start a game of Ms. Pac-man and then hit auto adjust while it is playing. 95% of the time the screen will center and all is well, but on some monitors, it will just not center. Manually adjusting the horizontal button all the way to 0 will not move the screen enough for it to be centered. Have you seen or heard of this? Do you have any idea why this would happen on a handful of monitors and not the majority of them?
Thanks,
Gary
