If the digital display on your RS277ACPN is not illuminated and will not light up when you press any of the buttons, it will likely require service. If it is illuminated and does not respond, please make sure the Child Lock is not engaged. To activate or deactivate the Child Lock, hold the Lighting/Child Lock button for 3 seconds.
If the display is still unresponsive, please submit an online service request through the link below, or call 800-SAMSUNG to speak with an agent who will be happy to assist you.
