CPS 2 super gun Picture loss issues!

[Jimd0586]

Hi all. I’m new to arcades. I bought a super gun on AliExpress. Yes I know some people say they are junk, but I have their NeoGeo box and it works great. So I took the plunge, bought their Jamma Cbox and a CPS 2 A and B board set.

I have the super gun connected via component to a Retrotink which converts it to HD, then to a scan line generator and into my HD tv. It works fine, Sound and controls work. I even got the kick harness working. However, occasionally my tv will lose a signal for a few seconds. When the picture and sound comes back the game is still going. So the board isn’t resetting.

Is this a board issue? A Cbox issue? A power issue? Any idea what the culprit may be?

Thanks,

Jim
