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, sat-

ellite channels, and others. Here are some examples of station-

ary 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.

Placement of the TV

• 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 perfo-

rated back cover of the set.

Cleaning

• 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.

SYMPTOMS

SUGGESTED STEPS TO TAKE

General

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 playback 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 problem is inherent

and does not require a service call.
