    Hello friends. I have a Gotlieb Panthera pinball machine and have a problem. The number 20 on the playfield(bonus) is out and I've tried changing the bulb to no avail. Any suggestions would be greatly appreciated because I have no clue about electrical stuff. Thank you.

    One bulb not working on Gottlieb System80 pinball machines can be anything from this list:
    - bad bulb socket
    - wire or ground braid to that particular bulb socket broken-off somewhere
    - bad pin in connector header on the driver board for that lamp
    - bad drive transistor for that bulb on the driver board (easier to find-out which transistor with the game manual)

    Some level of electrical troubleshooting and knowledge would help to fix this.
    Plus for safety...

    Note: Never unplug or reconnect connectors on boards with the machine powered ON,
    or poke under the playfield with a metal tool... or serious damage can occur on boards.

    Good luck!
    -Sylvain.
