INFO — No Immediate Action

Display Error — the front LED display or LCD user interface is not communicating with the main control board, or the display is showing garbled characters

Equipment: Dixie Narco Glass-Front Vending Machine

Step-by-Step Troubleshooting

  1. Check the display ribbon cable connection at the control board — a loose ribbon cable causes garbled or missing display characters
  2. Power cycle the machine — display communication errors often resolve after a cold boot resets the display controller
  3. Inspect the display connector pins for corrosion — humid environments cause connector corrosion that disrupts communication
  4. If the display is completely blank but the machine is otherwise functional (accepts payment, dispenses product), the display module itself may need replacement
