Quoted from Seatmandan:I took a peek, seems like a lot of great pinheads already pointed you in the right direction! seems to me that all your locked on flashers are board related, the upper RH switch is probably dead and needs to be replaced, and as far as your LEDs fluttering, that's normal unless you buy LED OCD boards from Pinsider Herg and install them.
Thanks for taking the time to check in. I'm reading what people have replied with, and following up the suggestions.
I'm strongly considering spending the $42 for the Rottendog replacement A-16100 8-Driver PCB board to hopefully address the locked on flashers.
Also going to replace the Left Ramp switch with a new one.
As for the lamp issue, the issue is not that the lamps are fluttering (forgot to mention they are not fluttering), it's that when running through the "Single Lamps" (T.8) test for individual lamps, additional lamps are turning on when they are not the lamps being selected. For example, when I select Lamp 75 "Power Payoff" to test, not only does lamp 75 light up as it should, but lamps 84 (Piano Red) and 85 (Slot Machine) also light up, when they should not. I'll be updating my thread with a more current Lamp Matrix findings table that I updated after additional troubleshooting took place last night.
Thanks again for everyone's time and assistance.
