hey guys so my flash game is just getting GI. Both leds on the system 4 cpu board are red as soon as power is applied and never flash or blink at all. I get no display or flipper controls nothing. Tested the power supply 5v is good. 12v is near 10.6v. High voltage is fine too. Boards are very clean. No physical damage anywhere. Just replaced the 40pin. No change. Anybody have any ideas where to go from here.
