14.2. LCD TV pixel faults
5 Pixel
Sub-Pixel
Despite the state-of-the-art production methods, in rare
cases there may be individual or multiple pixel drop-outs
(dead pixels) due to the highly complex technology.
For active matrix TFTs with a resolution of 1920 x 1080
(MD 20113 / 20114) / 1366 x 768 (MD 20058 / 20059)
pixels, which are each made up of three sub-pixels (red,
green, blue), there are a total of approx. 6.2 (MD 20113 /
20114) / 3,1 (MD 20058 / 20059) million control elements
in use. Occasionally pixels or individual sub-pixels can fail
or become incorrectly controlled because of this very high
number of transistors and the extremely complex manu-
facturing process used in this context.

The permitted number of defects for every type named
above in each class of pixel defect refers to one million
pixels and must be converted accordingly to match the
physical resolution of the display.
Your device complies with the European ISO 9241-307
Class II standard (pixel fault class).

DANGER!
Risk of electric shock!
There is a risk of death due to an elec-
tric shock when the housing is open
and you touch parts inside the device!
does not contain any parts requiring mainte-
nance. Always unplug the device and discon-
nect all cables before cleaning!
In order to protect the television from scratches, pro-
tective film has been applied to the high-gloss finish.
Remove the film after you have set up the TV correctly.
If the high-gloss finish becomes dirty, wipe off the dust
first. Then wipe down gently with a cleaning cloth. If
you do not wipe off the dust first, or wipe the high-
gloss finish too vigorously you could scratch the high-
gloss finish.
Do not use solvents, corrosive or gaseous cleaning
agents.
Clean the screen with a soft, lint-free cloth.
Ensure that no water droplets remain on the LCD-TV.
Water can cause permanent discolouration.
In order to avoid damage to the device, water must
not penetrate into the interior of the device under any
circumstances.
Do not place the screen in strong sunlight or near ul-
traviolet light.
Store the packaging material in a safe place and only
use this packaging to transport the LCD-TV.
