Home theater system, 
sound bar, or external 
speaker system may not 
be turned on or may not 
be set up correctly
• 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.

securely to your TV.
Bad content, no audio
• Make sure that the selected channel or content is intended to be 
broadcasting with sound.
Cables may not be 
connected correctly
• 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 page 13.
• The audio cables you are using may be bad. Try a new set.
Poor picture
Light in the viewing area 
may be interfering
• Make sure that the room is not too bright. Light reflecting off the 
screen can make the picture difficult to see.
A connected camera or 
camcorder may be 
interfering
• 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.
Audio noise
Other devices may be 
interfering
• 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.
After images 
appear
• 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.
