How to Fix / Troubleshooting

Safety: Unplug the unit before removing the control panel.

  • Inspect buttons: Check if any buttons feel stuck or do not spring back. Gently work them to free any debris.

  • Check ribbon cable: Ensure the flat ribbon cable between the keypad and main PCB is fully seated and not damaged.
  • Clean contacts: If accessible, lightly clean the keypad connector contacts with contact cleaner.
  • Replace control panel: If F1 persists and buttons are unresponsive, replace the control panel / keypad PCB with a TCL-compatible assembly.
