Safety: Disconnect mains power before removing the display panel.

Steps:

Check power: Confirm the freezer is powered (compressor or fan noise, interior light).
Access display: Remove the control panel cover and inspect the display PCB and connectors.
Reseat connectors: Disconnect and reconnect the ribbon cable or harness to ensure good contact.
Inspect for damage: Look for corrosion, burn marks, or cracked components on the display board.
Replace display: If damaged or unresponsive, replace with a Bosch-compatible display/UI board.

Freezer display is blank or flickering, but interior light may still work.
