Troubleshooting

Remedy
Is the volume too low? Press the Volume button.
Is mute turned on? Press the Mute button, or the Volume button.
Are the TV speakers turned off on the onscreen display (OSD) menu?
Press the Menu button to open the OSD; press the Down Arrow
button to select Audio, and then press the OK button; press the
Down Arrow button to select Speaker, and then press OK; press the
Down Arrow button to select On, and then press OK. Press the Menu
button to close the OSD.
Check that the device outputs audio over HDMI in PCM format. Change
the device setting if necessary.
This TV does not support audio input over HDMI in Dolby Digital format.
For more information, see "Understanding audio output" on page 71.
To use Dolby Digital output from your digital source device, connect the
digital output of your device directly to the input of your AV receiver or
external sound system that supports Dolby Digital. For more information,
see "Connecting an external sound system" on page 18.
Are the connections to the input signal source component correct?
Double-check that the cables are properly inserted into the
color-coded connectors.
Is the input signal source turned on? Turn on the set-top box,
DVD player, or other device that you are trying to view.
Is the correct input signal source selected? Press the Source button on
the remote control, and confirm that the source is selected.
Press the Menu button on the remote control, or on the TV:
If the OSD appears, check the cables to the input source, and
then press the Source button on the remote control (or the TV) to
select the input source.
If the OSD does not appear, see the next symptom, "There is no
power."
