So awhile back I did a dumb move.. worked on this game with the power on... grounded out a lamp on Q89 I suspect.
I replaced the Q89 transistor to no avail.
So I sent the board out for repair and rebuild, put a rottendog in it.
Still have the same issue.
So I just tested the three Diodes on the Q89 lamp row.. one was dead. So I replaced it.
Still in the same boat. Any direction?
