LCD TV Image Retention
Image retention damage may occur on TVs that display the same
static images on screen for a prolonged period of time. A
prolonged period of time is 12 consecutive hours of non-use. To
avoid image retention image damage to your TV screen, you
should always activate a screen saver application or turn off the
TV when it is not in use for a prolonged period of time. Image
retention is a condition that may occur on all LCD TVs.

LCD Pixel Policy

The LCD display panel is manufactured using highly precise
technology; however, occasionally some of the tiny pixels of the
panel may stop working properly. This is common with LCD
displays used in any television and is not specific to this product.
Pixels not operating properly are categorized into two types.
Dark pixel — when a pixel appears as a dark spot against a
bright background.
Bright pixel — when a pixel appears as a bright spot against
a dark background.
A very small number of malfunctioning pixels are allowed under
product limited warranty.
