Game works and plays fine. Sound is not working, no hum from speakers.
I have replaced both tda2030 amps and big caps and the two other caps. As well as the 7815 regulator.
One diode tested bad, and had no effect on audio. Probably not in the audio portion. All resistors test good.
I reflowed all of the header pins as well. Only other odd thing is putting fresh coin door bulbs in results in them burning out at about 25 seconds.
I do have a similar audio pcb in road blasters, it is identical but a different rev. And uses a 7812 instead of a 7815. Could I swap it in to test or vice versa. Or would that hose em?
Additionally, there are no errors in test mode.
Thanks
