Hello everyone. I have an original MK3 pcb (not UMK3) that has issues. When I fire up the cab, instead of hearing one test tone, I hear five! All the roms pass the self test, but when the board gets to the sound test, it produces one test tone, then the "U86" ram chip goes red and I get the message that the sound section has timed out. I replaced the chip with another one from a UMK3 board that was bad with different issues. The problem remains. Also, if you actually try and play the game, it's extremely laggy. Most of the movements don't fully work either. If you press UP, the character just keeps standing up and squatting down without ever leaving the ground. Anyone have any advice or experience with this problem? I don't want to trash the board if it's something simple. I have 6 other boards that I can use parts from that are in various states of dis-repair if need be. Thanks - Mike.
