Hey all, I have a Time Pilot 84 PCB that works ok but doesn't have sound. I can hear light static, so I'm pretty sure the speaker and wiring is ok, I don't really have a way to test as it's the only working Konami board I have.
I looked at the schematic and poked around here looking at posts. I saw that in some cases a bad op amp was the cause. I looked at the schematic and see the LS174 feeds the amplifier, so I replaced it but no change. Would it likely be the amplifier chip, or other? Any other experiences out there with Konami no sound? Seems like a common problem but oddly there is few repair logs on it.
