I bought some untested boards recently, and finally got around to hooking one up. One is a Phoenix board, but I don't know if it's legit or bootleg. When it comes up, it says "GGI CORP" or something like that, and looks identical to a Centuri board. It's labeled TIM-8001 on the board. It's the same pinout as Crazy Kong (except the SPKR ground and SPKR + are opposite and no shield button). I don't get any sound though. My speakers are wired directly off the edge connector harness, so it's not tied to common ground. Is there a positive and ground on an actual speaker? (I didn't think there was) Any ideas on what to look for? I see some people have had problems with the 4600 chip for sound, luckily it's socketed. I did pop it out and reseated it just in case there was some corrosion, with no changes. A couple other issues, for some reason, player 2 side doesn't seem to work. It flips the screen in cocktail mode, but the controls don't do anything (they work on Crazy Kong, so I know they're wired up right). Also, when I boot up the board, most of the time it look scrambled, but sometimes it syncs up right. Is there something on the board that might be flaky to control that? I can't find any controls on my monitor to adjust it to fix it. Crazy Kong never comes up scrambled. Thanks for any insight
