    1. Press [ACTION MENU] button on remote
    2. Select Picture
    3. Select Light Sensor and set to Off

    Advanced Contrast Enhancer
    If the above setting has not been enabled, whilst there’s an absence in variance of ambient light intensity or obstruction of the light sensor is absent, please confirm if white subtitles are displayed on the screen or the scene has great variance in brightness.

    1. Press [ACTION MENU] button on remote
    2. Select Picture
    3. Select Advanced Settings
