Eco Sensor and screen brightness
Eco Sensor adjusts the brightness of the TV automatically. This feature measures the light in your room and 
optimizes the brightness of the TV automatically to reduce power consumption. If you want to turn this off, go to 
 
>   Settings > General > Eco Solution > Ambient Light Detection.
 • If the screen is too dark while you are watching TV in a dark environment, it may be due to the 
Ambient Light Detection function.
 • Do not block the sensor with any object. This can decrease picture brightness.
Still image warning
Avoid displaying still images (such as jpeg picture files), still image elements (such as TV channel logos, stock 
or news crawls at the screen bottom etc.), or programs in panorama or 4:3 image format on the screen. If you 
constantly display still pictures, it can cause image burn-in on the LED screen and affect image quality. To reduce the 
risk of this adverse effect, please follow the recommendations below:
 • Avoid displaying the same TV channel for long periods.
 • Always try to display any image in full screen. Use the picture format menu of the TV for the best possible match.
 • Reduce brightness and contrast to avoid the appearance of after-images.
 • Use all TV features designed to reduce image retention and screen burn. Refer to the e-Manual for details.
Caring for the TV
 • If a sticker was attached to the TV screen, some debris can remain 
after you remove the sticker. Please clean the debris off before 
watching TV.
 • The exterior and screen of the TV can get scratched during cleaning. 
Be sure to wipe the exterior and screen carefully using a soft cloth to 
prevent scratches.
 • Do not spray water or any liquid directly onto the TV. Any liquid that 
goes into the product may cause a failure, fire, or electric shock.
 • To clean the screen, turn off the TV, then gently wipe away smudges 
and fingerprints on the panel with a micro-fiber cloth. Clean the 
body or panel of the TV with a micro-fiber cloth dampened with a 
small amount of water. After that, remove the moisture with a dry 
cloth. While cleaning, do not apply strong force to the surface of the 
panel because it can damage the panel. Never use flammable liquids 
(benzene, thinner, etc.) or a cleaning agent. For stubborn smudges, 
spray a small amount of screen cleaner on a micro-fiber cloth, and 
then use the cloth to wipe away the smudges.
