I have a MK II board that when connected everything is fine but two little things. First there is a loud pitch humming when the game is on coming from the speakers, the gameplay sounds come out fine but there is still the hum and I am not sure what to look for.
Second it will keep adding credits, I will sit at the start screen and it will add 2-3 credits at a time every few seconds until it gets to 30 which is where the max is set. I could put this on free play but it will always bother me until I get it working.
The only thing I can say is the the light on the sound board stays lit red but with the main PCB there are two lights one stays lit red and the other constantly flickers like when a computer light shows its doing something.
Thank you;
