Video issue with Denjin Makai II board

[neoretro75]

Hi guys,

Need help: I bought a Denjin Makai II board a few months ago. It works perfectly on my Astro City cab and via my LED TV set x X-RGB Mini combo BUT I got video issues when playing the board on my two Supergun (Sigma Raijin and HAS from RGB) hooked to my BVM via RGB scart > BNC. The thing is I don't have any issue with my others boards when playing on my supergun.

Below pics that show the problem I have, you can see the colors bleeding on the characters and on the texts... Also a pic of my board (original board).
Can you give me some leads to fix this?

Thanks in advance for your help!
