Hi All,
I have a 1980 Williams Omni shuffle alley that I am bringing back to life which has been going great the one last thing I have to fix is a 6digit Slave display that the A segment is out on one display only. I cleaned the edge I also put that display on another connector and get the same results. All other displays look fine so I’m assuming that it’s just the slave that’s the issue and not the master. Anyone have any ideas for me to look into???
Wow, strange. What did they do with displays on that game? It looks like a 2-board design? Is there a component board for each display or a display driver / master display board like most older Williams games? Looks like it could just be blank board on the bottom aside from making the 90 degree angle and connecting to a card edge in the back?
If there's no actual circuitry per display, and you've swapped positions, only possibly thing to trace is from the card edge connector to the plasma display pins.. aside from that, could be an internal break in the plasma display. I'd think you'd have ruled out anything with the display circuitry (assuming there's not separate circuitry per display) simply by moving the display to another working position.
There is a master display and no circuitry on the display itself and yes it does have a funky 90 degree turn. I have toned out from the pin to the end of the edge connector so I guess I will have to buy new glass boooooooo.
