• Check the service switches [Green, Red, Red, Black] for loose connections or bad ground.
• Check the associated wiring harness to/from the CPU/sound board, connector J13.
• Check the CPU/sound board for possible failure
• Check the service switches wiring harness for poor or no connection and/or broken wires.
• Check to make sure the game is not in Free Play. If the game is set to Free Play, adding service credits is not
required.
• Check the service switches wiring harness for poor or no connection and/or broken wires.
• Check the dot matrix display for loose wiring harnesses, for poor or no connection, and/or broken wires.
• Check F1 (3/4A fuse) on the display power supply board.
• Check for stuck switches on either of the red buttons.
• This is normal. These switches are deactivated as they are part of the switch test.
• Check the flipper buttons for loose connections or bad grounding.
• This is normal only in diagnostics switch & active switch tests
• Some functionality of the service menu may not have been completed during development. If absent, it should
only be a non-critical function such as the "HELP" icon, which will explain the usage of icons. When completed,
a software update will correct the problem. Software updates are announced via Service Bulletins and on our
website (http://www.sternpinball.com/service-bulletins)
• Ensure the power interlock switch is pulled out.
• The volume adjustment can only be made when in the attract mode.
• If you cannot clear the situation by exiting back one menu, exit completely out of the service menu and re-
enter. If the problem persists, call technical support for additional help.
