Solution
• The problem may be caused by
a poor or weak signal from the
broadcaster or cable TV
provider.
• If you connect to cable 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 TV provider about
upgrading to a set-top box.
• Make sure that the antenna or
cable TV is connected correctly
and securely. See Connecting a
cable or satellite box
page 24 or Connecting an
antenna or cable TV (no box)
page 28.
• If you are using an antenna and
the signal strength is low, adjust
the antenna or use a highly
directional outdoor antenna or
set-top antenna with a built-in
amplifier.
• Make sure that the video cables
are connected correctly and
securely to your TV.
• The video cable(s) you are using
may be bad. Try a new set.
• Other devices (for example, a
surround sound receiver,
external speakers, fans, or hair
dryers) may be interfering with
your TV. Try turning off one
device at a time, then back on
to determine which device is
causing interference. After you
have determined which device
is causing interference, move it
further from the TV to eliminate
the interference.
• Use a highly directional outdoor
antenna, cable TV, or satellite
TV.
• A few bright or dark spots on an
LCD screen is normal. It does
not affect the operation of
your TV.
