I had a fully working Gottlieb Chicago Cubs Triple Play. Not long ago the display went out during game play. I turned the pin off and restarted after waiting a minute or two. Upon turning it on, the display functioned normally. After a couple of weeks and many games, the display went out again during game play. This time after a reboot, the display would not function.
Checked all fuses - all tested good
Cleaned the connector traces and rest the connectors
Re-pinned the display connectors
I see no obvious problems on the display board ( burn marks or bad traces)
I switched out the power supply with a spare. The display did not work.
Any suggestions on what check/ do next ? The game isn’t nearly as much fun without the display.
