Why do you think a transistor has gone out?
Note that the violet-vio/wht GI lamp lines also run to the two lamps on
the coin door in the main cabinet. One problem that many games of this
era have is that the glass lockdown bar latch inside the coin door will
vibrate over to the left, and short out against the lamp socket on the
right coin slot. This will blow a fuse on the driver board in the
backbox.
So first, check the 5 fuses in the lower left corner of the driver board
in backbox.
Secondly, inspect the lockdown bar latch. Insulate it with some heat
shrink tubing or other comparable insulator so that this problem doesn't
happen again.
Hope that helps!
