Trackmarks on top of black screen

Post by Akuma »

Got some strange woe with the Super Neo 29. Nothing big but I'd like to know what it is (and what to do against it).

It only happens for a split second - when playing King of Fighters 96 or Real Bout Special on the MVS-1, between fights, when the screen goes all black, there is a noticeable pattern on top of the screen which looks like track marks:

Is this a common woe? Something that can be fixed easily? If it's too complicated, I guess I'll have to live with it...

its either your screens volts is too high thus causing flyback lines,your abl circuit is not functioning correctly or maladjusted or more than likely just some kind of crap that only the mvs mobo throughs up-what happens if you plug in a different jamma board?

I have a similar pattern, but all over the screen with all my pcbs in 15kHz and 31kHz as well. Noticeable espcially on black backgrounds.
