    Default Terminator missing led segments

    Just picked up an original terminator. Everything works except for the credit board that has missing segments on the leds. It is the same segment on all numbers. I will try to attach pics. It is IGT part # P105G-A.

    as its the same segment on both. it might be a mutiplexing issue. if you have 2x 2 digital 7 seg displays. that would be 28 segments with one common. But as you can see, there isn't 29 wires there. (also not including the reply or medal light or the display above)

    If you have a good multimeter, you should be able to test the leds.

    I happened to hit a bonus just now and the blue leds above have the same segment out. I don’t have a multimeter and wouldn’t know how to test properly

    could be a dodgy connector. Try the old favourite of unplugging and plugging in a few times. Or it could be the resistor that feeds that segment. or a number ofother things. but it doesn't sound like its the actual led at fault.

    Borrowed a multimeter and tested leds and all segments worked.

    The next thing I would do, is follow the circuit board track, from the fault segment back to the wiring loom.
    if no components on the board. then following the wiring loom back.
