Having an issue with 4 flashers not working in test or during game play. If you look at the schematic, they are the 4 flashers connected to Q41 (black/blue +orange wires). I know the bulbs are good, I have continuity from the sockets all the way to the CPU board. I have replaced Q41, it's pre driver transistor, and the TTL for that part of the circuit on CPU pcb. I have also replaced D14 on the PPB board thinking that could be causing me issue. I am getting voltage at all the bulb sockets as well. I'm at a bit of a loss as to what else could be giving me this issue, so I'm reaching out here to the pinside experts! This is the last thing I need to fix before we reach that magical moment where everything works for awhile, so any help is appreciated. Thanks y'all!
