Monitor Distortion

[davido]

First time on site, not sure if this is how to post a question. Sorry. I have a "std." arcade monitor. I have noticed a small (1" or so) section along the top and bottom of the monitor that have an s-shaped squiggle. The rest of the screen is ok. I've checked the voltage at the power supply, which was 5.3 V and -4.9 V. I've switched the motherboard with other jamma ready games and no change. Would this be a monitor chassis issue? Thanks, David

Look up the list. You'll see what you need to add here.

start by adjusting the horizontal phase/hold/frequency(however it is noted on your chassis)
