Accessing and Replacing the Controller Board
The display controller is mounted to the back sheet of the cabinet in the lower left corner.
The controller receives, interprets, and activates the information from the computer to the
appropriate LEDs on the display.
The controller board includes three LEDs:
1. DS1 should be on whenever power is applied to the board.
2. DS2 should have a steady flash to indicate that the controller is running properly.
The normal rate is about once per second. The run LED will flash faster when the
controller is in test mode.
3. DS3 should flash when receiving information from the light sensor.
4. See
Figure 34 below for LED and connector locations.
