while another connected device is turned on, the
picture may be poor. Turn off one or more devices.

Audio noise
• Other devices (for example, 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. Once you have determined which
device is causing interference, move it further from
the TV to eliminate the interference.

settings” on page 21.

correctly and securely to the back of your TV.

• 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.
