17.2. Smart 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
pixels, which are each made up of four sub-pixels (red,
green, blue, white), there are a total of approx. 6.2 million
control elements in use. Occasionally pixels or individ-
ual sub-pixels can fail or become incorrectly controlled
because of this very high number of transistors and the
extremely complex manufacturing 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 defect class). Pixel defects up to
the specified maximum number are not covered by the
warranty

18. Cleaning
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!
Do not open the housing of the device. It
does not contain any parts requiring mainte-
nance. Always unplug the device and discon-
nect all cables before cleaning!
You can increase the lifespan of your Smart TV by taking
the following measures:
•
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 Smart 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
0
use this packaging to transport the Smart TV.
