Alright, do after getting my supergrafx working thanks to this board, I figured I would ask about my current problem. I'm trying to RGB mod this (have done plenty of rgb mods with no issues.) But I'm just having so many issues its driving me crazy. Long story short, I ordered an rgb amp from a guy on this board(sorry I don't recall your sn.) Amp arrived, installed perfectly fine. Closed it back up and it worked for a few minutes and then the green stopped displaying. Its not the amp because I was having the same issue with my own amp(thus why I ordered one).
I swapped the 5pin with an 8pin din, and I'm using a doujon dance cable. Cable works perfect with my duo r.
No green is displaying for whatever reason. I've tapped from both the expansion port as well as the huc6260. Same issue from both. I get continuity from pin 47 to the green pin in my scart cable when hooked up so I know the path isn't being obstructed.
I get the correct colors when I use the composite cable though. I really don't know what else to try. I don't see anything that would be grounding the signal at all. And like I said, it worked for a few moments before it just dropped out.
Any suggestions on what to check for?
Thanks a bunch
