Sound
Symptom Suggested Solution
1. There is no sound even when the volume is
turned up.
• Check audio source in Device Menu.
• Check to see if the MUTE button is on.
• The TV’s “Listen to:” setting may be set to SAP.
• Check that the “TV Speakers” setting is On in the Audio/Video menu.
2. The sound does not match the screen
picture.
• NetCommand® is set up incorrectly.
• The TV’s “Listen to:” setting may be set to SAP.
• If using stereo or A/V receiver speakers, check their input selection.
• If using stereo or A/V receiver, check that AUDIO OUTPUT on TV’s back
panel is connected to the A/V receiver.
3. The A/V Receiver is the selected audio
source but there is no sound.
• Check to see if the A/V Receiver power is turned on. After the power is
turned on, redisplay the Device Selection menu and press ENTER to allow
NetCommand to correctly select the A/V Receiver input.
• Verify the connections and NetCommand setup for the A/V receiver and the
desired source device, if any.
From the NetCommand menu, select Review. Check the Review screen to
see if the A/V Receiver inputs and device listed correspond to the physical
connections on the A/V Receiver. If they do not match, either change the
physical connections or change the NetCommand setup. To change the
NetCommand setup, make the audio source the TV speakers and select a
source other than the one you want to change. Next select the Change option
on the Edit NetCommand menu to change the A/V receiver input for the
device on the Connection screen.
