Problem Solution

fill the screen.
There are black
bars around the
picture.
• Change the aspect ratio. An
increasing amount of digital TV
and movies are presented in
wide screen (16:9). See
“Adjusting the TV picture” on
page 42.
No picture (screen
is not lit) and no
sound.
• Press (power) on the TV or
the remote control.
• Make sure that the video cables
are connected securely to the
side or back of your TV.
• Adjust the contrast and
brightness. See “Adjusting the
TV picture” on page42.
• Make sure that the power cord
is plugged into a working
outlet.
• Make sure that the correct
video input source is selected.
See “Selecting the video input
source” on page35.
• Try another channel. The station
may be experiencing problems.
• Make sure that the incoming
signal is compatible.
• Make sure that the antenna or
cable TV is connected correctly
and securely. See “Connecting a
cable or satellite box” on
page 12 or “Connecting an
antenna or cable TV (no box)”
on page17.

Picture quality is
good on some
channels and poor
on others. Sound
is good.
• The problem may be caused by
a poor or weak signal from the
broadcaster or cable TV
provider.
• If you connect to cable or
satellite TV without a set-top
box and experience poor
picture quality, you may need
to install a set-top box to
improve signal reception and
picture quality. Contact your
cable or satellite TV provider
about upgrading to a set-top
box.
