My sound board is bad.
I have another sound board and the game works great.
When I put in the suspect sound board,
(if I remember right)
TP1 is like 2volts
TP2 is13 volts
TP3 is gnd
TP4 is 1 volts
Bridge recitfier off fuse is pulled and tested good.
by the way, the rom is bad.
I tried the suspect rom in the working board and the sound did not work, so something blew out the rom in the non working board.
I also changed the 5 volt regulator.
What is causing the voltage to be wrong.
Thanks,
David
