Lines running through the screen what gives?

I have several arcade cabinets most displaying perfect pictures on all games.

However I have 2 cabinets that seem to cause issues visually.

Very faintly on both My Capcom Big Blue Cp2 and Neo Geo MVS Big Red 4 slot cab have faint lines running diagnally through the screen.

Is this due to something wrong on my power supply?

Do I need to adjust the monitors somewhere?

Is it time for a Cap Kit on both?

They are older cabs the Capcom one being from 1993 and The Neo Geo MVS from 1989.

Just wondering as it annoys the hell out of me sometimes and my Atomiswave looks like $hit on my Capcom Cab.

I have a thread a couple down from this where I'm having the problem you describe with Atomiswave. The diagonal lines are called "herringbone" and are usually due to a ground problem. But only Atomiswave gives me anything of a problem. Is the power supply noisy when you use Atomiswave?

My power supplies are not noisy

Only the picture has a issue

I hope I can fix this

Establishing a good common ground between mobo, monitor and psu should fix the problem.
