Solution
• Make sure that the room is not
too bright. Light reflecting off
the screen can make the picture
difficult to see.
• If an S-VHS camera or a
camcorder is connected while
another connected device is
turned on, the picture may be
poor. Turn off one or more
devices.
• Adjust the contrast, color, and
brightness settings. See
Adjusting the TV picture
page 38.
• 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 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.
• Adjust the audio balance. See
Adjusting sound settings
page 40.
• Test the TV's speakers. See
Testing the TV speakers
page 56. If one or both of the
speakers fails, try one of the
following solutions:
• Make sure that the audio
cables are connected
correctly and securely to your
TV.
• Make sure that the audio
cables are connected to the
AUDIO OUT jacks on the
connected device.
• Try a different set of audio
cables.
• Make sure that the sound on
the connected device is not
muted.
• Try connecting the device to
a different TV. If you do not
hear sound, the problem is
with the device.
• Do not display a still image,
such as a logo, game, or
computer image, for an
extended period of time. This
can cause a permanent
after-image to be burned into
the screen. This type of damage
is not covered by your warranty.
