Hello all. I have a Williams Junk Yard pin. When it is first powered on, it goes ding, then 5 gongs. The manual sais that's S5 failure. I believe that's on the audio visual board. The game plays great, sound appears 100%, but the display sometimes displays, sometimes freezes, sometimes blank. Would replacement of S5 correct this? I thought S5 was just for sound?
I have replaced the display with a color rgb version and have the same issues. The diagnostic leds are all lit properly. Suggestions? Thanks!
