Safety: Unplug the cooler before removing the control panel.

Steps:

1. Inspect front panel: Check for signs of moisture or spills around the display area. Dry thoroughly.
2. Access display PCB: Remove screws securing the top/front trim and gently pull out the display board.
3. Reseat connectors: Disconnect and reconnect the ribbon cable and any harnesses between the display and the main board.
4. Check for corrosion: Clean light corrosion with isopropyl alcohol and a soft brush. Allow it to dry completely.
5. Replace display board: If the display remains dim or unreadable, install a new NutriChef display PCB.

The wine cooler powers on, but the display is dim, flickering, or unreadable.
