Changing time settings

You can change time settings to suit your preferences. You can find the following settings by navigating from the Home
screen menu to Settings > Time:
• Sleep timer—Set a time delay after which your TV will automatically shut off. This setting reflects the setting you can
make in the Options menu from any TV input, as explained in
timer setting is not input specific.
• Time zone—Select whether to set the time zone automatically or manually, and if set manually, select your current
time zone. Typically, a TV connected to the Internet can discover its own time zone automatically, and a TV that is not
connected to the Internet must be set manually. Initially, this setting is made when you set up the TV tuner, as
explained in Setting up Antenna TV
data.
• Clock format—Select whether to display time in a 12-hour or 24-hour format, or to turn off time display. This setting
is available only on TVs that are connected to the Internet. Non-connected TVs do not display time.

Scanning for broadcast TV channels again

There will be times when you need to create a new channel list. For example, you:
• Change cable providers
• Reorient your TV antenna
• Move to a different city with different channels
Whenever you need to update your TV channel list, you can repeat the channel scan.
Tip
Repeat the channel scan from time to time to make sure you are receiving all of the
latest channels. Broadcasters add and remove channels, move channels to different
parts of the spectrum, and change the power levels of their channels periodically.
To repeat the channel scan, from the Home screen menu, navigate to Settings > TV inputs >Antenna TV> Scan again
for channels. Then select Start finding channels to begin the channel scan process. The screens and options that
appear during this process are identical to those described in

Using your TV in a home theater

Your TV has several features that make it an ideal TV for a home theater. But you might not notice them because they
remain in the background until you decide to use them.

Turning off TV speakers

When you use your TV with a sound bar or an external amplifier and speakers, you'll probably want to turn off the
internal TV speakers.
To turn off your TV's built-in speakers, in the Home screen menu, navigate to Settings > Audio > TV speakers and
change the setting.
Tip
Your TV's internal speakers can be enabled and disabled automatically as needed by
system audio control, as described in
internal speakers are also turned off when you use the headphone jack.

Changing the audio mode

Your TV has two audio modes, accessed by navigating in the Home screen menu to Settings>Audio>Audio mode:
• Stereo—Use this setting for internal speakers, headphones, and external stereo amplifiers connected through the
HDMI1 (ARC), OPTICAL DIGITAL AUDIO OUT, or headphone jack.
• Auto—Use this setting to automatically detect the best audio setting based on the audio stream in the content
you are watching. If you have connected your TV to an external Dolby Digital or Dolby Digital Plus compatible
amplifier, receiver, or sound bar through HDMI1 (ARC) or OPTICAL DIGITAL AUDIO OUT, your TV automatically
selects the appropriate surround sound capabilities of the device based on the characteristics of the current
program.
