LCD Screen
• Although the LCD screen is made with high-precision technology and has effective pixels
of 99.99% or more, black dots or bright points of light (red, blue, or green) may appear
constantly on the LCD screen. This is a structural property of the LCD panel and is not a
malfunction.
• The LCD screen is made with high-precision technology and to achieve a high level
of performance and picture quality, this TV’s backlight setting is set to maximize the
brightness of the TV. However, uneven brightness may be observed when the LCD TV
is viewed in a dark ambient without an input source or a blank screen. This condition is
normal and not a malfunction of the TV. Changing the Picture mode, Backlight setting,
enabling the Light Sensor, or turning on the Power management will improve this
condition. In order to ensure long performance of your set and reduce the risk of screen
burning, please observe the following precautions: 1)Does not display still image (still
computer and video game images, logos. pictures, text and images displayed in 4:3) for
extended periods of time; 2) Use a screen saver when using a computer.

panel.
• Do not push or scratch the LCD screen, or place objects on top of the TV. The image
may be uneven or the LCD panel may be damaged.
• If the TV is used in a cold place, a smear may occur in the picture or the picture may
become dark. This does not indicate a failure. These phenomena improve as the
temperature rises.
• Ghosting may occur when still pictures are displayed continuously. It should disappear
after a few moments.
• The screen and cabinet get warm when the TV is in use. This is not a malfunction.
• Avoid spraying insect repellent with volatile material on the screen.
