Maintenance and Troubleshooting

Complete the following steps to remove the controller from the display:
1. Disconnect power from J5.
2. Remove all power and signal connections from the board. “Locked”
connectors are released by pushing apart the latches then carefully pulling
them from the jack. When replacing the board, it is helpful to have the
cables labeled for easier replacement.
3. Remove the six screws holding the board in place with a 3/16” nut driver.
4. Follow the previous steps in reverse order to install a new controller board.
The address on the controller is only recognized on power up. When changing the
address on the controller board, power down the display, change the address, and
reenergize the display.
