TROUBLESHOOTING TIPS
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.
No Picture
•Check antenna connections. Are they properly secured to the
TV's ANT 75Ωplug?
•Check the TUNER MODE control for the correct tuner set-
ting.
•Try running the Auto Program feature to find all available
channels.
•Press the AV button on the remote to make sure the correct
signal source is selected (FRONT, AV1, AV2, Current
Channel, etc.).

•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.

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

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.
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 pic-
ture 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.
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 perforated
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 abra-
sive. 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.
