Startup questions
Symptom Remedy
I do not hear sound at power-on,
even though there is an image.
■ 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 in 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 press OK; press the down
arrow to select On, and then press OK. Press the Menu button to
close the OSD.
I do not hear sound from an HDMI
connected set-top box, DVD player,
or other device.
Check that the device outputs audio over HDMI in PCM format. Change
the device setting if needed.
This TV does not support audio input over HDMI in Dolby Digital format;
for more information, see “Understanding audio output” on page 32.
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.
I do not see an image at power-on.
■ 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 powered 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 on the TV,
to select the input source.
■ If the OSD does not appear, see the next symptom, “There is no
power.”
