I have a guy who set me a message trough e-bay and somehow he knew I buy mostly NON working boards and ask me for some help.
He has a sound problem, lack of any. The game plays fine. After looking at some pics of the board I recommended replacing the caps in the area of the amp. The amp is good, he can run his finger across the pins and get noise. I look further down and I see my favorite Zilog z80 chip. I told him I would send him a replacement to see if that is the problem.
If that is not the problem where else can I have him look at? I am thinking the Yahama chip or the supporting chips.
