Advice for wavy video interference on MVS

[Danystrat87]

Hello

I'm getting wavy video (the picture waves back and forth) interference on my MV1F & MV1C using a Parsec Supergun when playing on my 2 CRT TVs (and on my LCD displays using a retrotink).

My setup is:
Parsec Supergun (using the RGB (into a Retrotink Scart to Comp Convertor), component, s-vid, and composite outputs I still get the waviness)
Meanwell 125A PSU

Not sure how to get rid of the interference. Any advice would be appreciated.

Connect logic ground to field ground.

Thank you for the reply,

my PSU looks like this:

Do you mean connect a wire from GND to COM?

Yes.

Did it work?

No it didn't work, still getting the same wavy interference unfortunately.

These are the only boards that do it?

I only have the two MVS boards to test with the parsec.
However, I used to have a JROK in the MV1F and I had the same issues. And my MV1C used to be in a CBOX and it also had the waviness issue.
