Question:

What should I do if my refrigerator's display does not respond (no power, blackout, booting failure)?

Answer:

Check LCD Assembly Operation:

Ensure the refrigerator is turned on.

Test the touch screen and keys, along with voice recognition and proximity sensor.

If the LCD remains on a black screen, then service is required.

No Response with Any Touch or Action:

Normally, the touch control panel should boot up after displaying the SAMSUNG logo.

If the touch control panel shows only the SAMSUNG logo or never starts up, contact customer support for service.

Terms:

Panel - Refers to the touch control panel on the refrigerator.

No Power - Describes a situation where there is no electrical supply to the panel.

Blackout - When the display screen goes blank without responding to input.

Booting Failure - Occurs when the touch control panel fails to start up properly after displaying the SAMSUNG logo.
