WARNING Concerning Stationary Images on the TV
Screen:

Do not leave stationary or letterbox images on screen
for extended periods of time. This can cause uneven
picture-tube aging.

Normal use of the TV should involve the showing of pictures
that contain constantly moving and changing images that fill the
screen. Be careful not to leave nonmoving images on screen for
extended periods of time, or to display the same images on
screen too frequently, because subtle ghost images can be left
on the picture tubes. Sources of stationary images may be DVD
disks, laser disks, video games, CD-i disks, videotapes, digital
television boxes, broadcast channels, cable channels, satellite
channels, and others. Here are some examples of stationary
images (this is not an all-inclusive list; you may encounter
others in your viewing):

• DVD menus—listings of DVD disk content
• Letterbox black bars—shown at the top and bottom of the

TV screen when a wide screen (16:9) movie is viewed on a
TV with standard (4:3) aspect ratio.

• Video-game images and scoreboards
• Television station logos—present a problem if they are

bright and stationary; moving or low-contrast graphics are
less likely to cause uneven aging of the picture tube

• Stock-market tickers—presented at the bottom of the TV

screen

• Shopping channel logos and pricing displays—bright

and shown constantly or repeatedly in the same location on
the TV screen.

LACEMENT OF THE

• To avoid cabinet warping, cabinet color changes, and

increased chance of set failure, do not place the TV where
temperatures can become excessively hot; for example, in
direct sunlight or near a heating appliance.

• Be sure to allow a free flow of air to and from the perforated

back cover of the set.

LEANING

• To avoid possible shock hazard, be sure the TV is unplugged

from the electrical outlet before cleaning.

• Regularly dust the TV with a dry, nonscratching duster to

keep the TV clean.

• When cleaning the TV, take care not to scratch or damage the

screen surface. Avoid wearing jewelry or using anything
abrasive. Do not use household cleaners. Wipe the front
screen with a clean cloth dampened with water. Use even,
easy, vertical strokes when cleaning.

• Gently wipe the cabinet surfaces with a clean cloth or sponge

dampened in a solution of cool, clear water and a mild soap
or detergent. Use a clean, dry cloth to dry the wiped surfaces.

• Occasionally vacuum the ventilation holes or slots in the back

cover of the set.

• Never use thinners, insecticide sprays, or other chemicals on

or near the cabinet, as they might cause permanent marring
of the cabinet finish.

No Power
• Check the TV power cord. Unplug the TV, wait 10 seconds,

then reinsert the plug into the outlet and push the POWER
button again.

• Check that the outlet is not on a wall switch.
• Be sure the fuse is not blown on the AC power strip, if one is

being used.

TV's ANT 75

Ω plug?

ting.

channels.

• Press the AV button on the remote to make sure the correct

signal source is selected.

• Check the VOLUME buttons.
• Check the MUTE button on the remote control.
• If you’re attempting to hook up auxiliary equipment, check

the audio jack connections located on the front of the TV.

dow on the TV.

• Repeat channel selection.
• Add the desired channel numbers (using the CHANNEL

EDIT control) into the TV’s memory.

• Check to be sure the TUNER MODES are set to the CABLE

option and run the Auto Program feature to find all available
channels.

TV Displays white lines in letterbox when viewing a
DVD disc
• Some DVD Discs are encoded with as much as 30% more

video information to give the best possible picture quality.
With the DVD Player in the 16:9 picture format, the play-
back of this type of disc with extra video information, can
produce a number of small white lines in the upper portion
of the black letterbox area. With some of these discs, this sit-
uation is unavoidable and it does not require a service call.
