Atari Sanyo 14" monitor - looks terrible when inverted
So I picked up a Nintendo cabaret cabinet a few years back, and it had a 14" Sanyo monitor installed in it. Based on the burn-in I see:
I'm guessing it is/was a Warlords Cocktail monitor. Supplied by Sanyo, made for Atari. Built at the factory to run standard non-inverted video.
Here's what the montor looks like when you hook up a Ninendo signal from my DK:
Yep, standard video. No bleeding that I can see.
So I put a regular JAMMA board on there:
Picture looks great.
So, I put an inverter in between the signal and the monitor, and the first picture is what I got - colors all bleeding all over.
What can I do to fix this? Is it a ground issue? Monitor Chassis issue? I've tried 2 inverter boards and both gave me the same result.
