TRY THIS...
• Increase the volume.
• Make sure that the sound is not muted.
• Make sure that you do not have headphones connected. When
headphones are connected, no sound comes from your TV
speakers.
• If you want sound to play through your TV speakers, make sure
that your TV speakers are turned on.
• Change to a different audio mode.
• If you are using a home theater system, sound bar, or external
speaker system, make sure that it is turned on and is not muted
and that it is set to the correct source.
• If you connected an ARC audio device to the HDMI/ARC jack,
make sure that you have turned on the ARC feature.
• If you are using a home theater system, sound bar, or external
speaker system and have connected it with a digital audio cable,
make sure that you have set up the digital audio connection.
• Make sure that the audio cables are connected correctly and
securely to your TV.
• Make sure that the selected channel or content is intended to be
broadcasting with sound.
• Make sure that the antenna or cable TV is connected correctly
and securely. See Connecting a cable or satellite box
or Connecting an antenna or cable TV (no box)
• The audio cables you are using may be bad. Try a new set.
• 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.
• 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 your TV to eliminate
the interference.
• 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.
