My Gottlieb Universe just developed a problem.
None of the playfield lights are working although all of the features on the playfield ARE working (i.e. flippers, bumpers, targets etc).
I checked fuses and all 3 seem to be ok.
I have recently ordered the schematic but I don't have this in hand at the moment.
For the last few days the lights would go out when I nudged too hard , but they would always come right back on.
Now they are off all of the time.
Give me some ideas of what I should look for.
