• If your TV does not operate normally by following the operating

operating instructions because incorrect adjustment of other

Outdoor antenna grounding
If an outside antenna or cable system is connected to your TV, make sure
that the antenna or cable system is grounded to provide some
protection against voltage surges and built-up static charges. Article
810 of the National Electrical Code, ANSI/NFPA No. 70, provides
information with respect to correct grounding of the mast and
supporting structure, grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors, location of the
antenna-discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
Note to CATV system installer
Article 820 of the National Electrical Code, ANSI/NFPA No. 40 provides
guidance for correct grounding. Specifically, it states that the cable
ground must be connected to the grounding system of the building as
close to the point of cable entry as practical.
Condensation
Moisture will form on the TV if the TV is brought from cool surroundings
into a warm room or if the temperature of the room rises suddenly.
When this happens, the TV's performance may be impaired. To prevent
this, let the TV stand in its new surroundings for about an hour before
switching it on, or make sure that the room temperature rises gradually.
Condensation may also form during the summer if the TV is exposed to
the breeze from an air conditioner. In such cases, change the location of
the TV.
Mobile telephone warning
To avoid interference with your TV picture and sound, operating
problems, or even damage, keep your cordless and cellular telephones
away from the TV.
End of life directives
Your TV contains tin-lead solder. Disposal of this material may be
regulated for environmental reasons. Your TV also contains material
that can be recycled and reused.
Non-active pixels
The LCD panel contains almost 3 million thin film transistors, which
provide exceptionally sharp video quality. Occasionally, a few
non-active pixels may appear on the screen as a fixed blue, green, or red
point. These non-active pixels do not adversely affect the performance
of your TV, and are not considered defects.
