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

instructions. Adjust only those controls that are covered by the

operating instructions because incorrect adjustment of other

controls may result in damage and will often require extensive

work by a qualified technician to restore your TV to its normal

operation.

• If your TV has been dropped or damaged in any way.

• When your TV exhibits a distinct change in performance.

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.
