Quoted from CTDnEUG:I think this points again to the opto board. (Right?)
Yes, I do agree.
Check the 7-opto-board for leaking capacitor
Quoted from CTDnEUG:powered on the machine with J1, J2, and J3 on the opto board all connected. Still has the error message and rows 1, 4, 5, & 6 all lock on.
That looks like both LM339 are damaged (still could be caused by a short on playfield)
In this case, best replace both LM339 and put them on a socket.
