I just started working on a broken Shinobi. I've got the board on my test rig using a Sega16-2-JAMMA connector, a new switcher, and a CGA-2-VGA converter board. This setup works perfectly with other boards. The Shinobi however appears to work but has corrupt video. I don't have a speaker wired up yet but I'm almost certain this board (System16 B) has a dead suicide chip. I've attached a picture of the corrupt video. I ran through the built-in memory tests and everything passed. Any ideas on what could be wrong? Any help would be appreciated. I swear I thought I saw a post with the same issue a while back. I searched for an hour before posting this.
Thanks,
Jon
