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!

Occasionally the display runs ok, but now it's either all blank or frozen at "game over". Sometimes it displays half text. Remainer of game runs fine. When it works, it will play fine until it's turned off and on again.

I reset all the ribbon cables, checked all connections and chips on board to ensure they are tight. No change.leds ok.

Since the board freezes yet displays some text, does that indicate a cpu issue or video audio board issue? When the display is acting up, I can't get into the test mode. It just tones when I press any of the 4 buttons.

Should I start with new ribbon cables?

My test said right out lane switch 27, switch 67 & 68 bowl entry/exit. I adjusted 67 & 68 and they work now. I can't tell of I get a decimal as it won't display now.

Removed, inspected, and re-enstalled the old ribbons, no change, currently no display, I know the display functions, so I ordered cables, but expect it to be something bad on the board? Maybe the caps are dried out?
