Some displays dim or sleep during normal operation. Check the model's display behaviour before interpreting a dark screen as loss of power.
What the observation tells you
A screen that wakes normally with the permitted action is different from one that remains blank while the cabinet warms. Lighting, control response and temperature are separate observations. Do not keep unplugging the fridge merely to make the display illuminate.
A useful next step
Read the interface instructions and make a brief normal check. If cooling is unreliable or the screen fails to wake as described, report both facts. A display-saving feature should never be used to dismiss a genuine temperature problem.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
