How to Fix / Troubleshooting

Safety first: Turn off power before removing the front panel.

  • Check connections: Reseat the ribbon cable or connector between the display/LED board and the main control board.
  • Inspect for moisture: Look for condensation or corrosion on the UI board; dry and clean if minor.
  • Test operation via app: If the app still shows correct status, the issue is limited to the UI hardware.
  • Replace UI module: If flickering or blank display persists, replace the display/LED board as a unit.
