Think I have a bad power supply board on my Fuji Thunderbirds 2 (Classic) machine. When I power on I have power to some of machine briefly then goes out. No LEDs on other controller boards. Replaced the transformer and nothing really changed. Power supply board is FUJI P0301C KYOEI. I am about ready to reverse engineer the circuit board to troubleshoot but hoping someone might have some other ideas before I invest a lot of time. Replacement board or perhaps some circuit diagrams would be handy if someone has.
