Possible Remedies
❏
Press MUTING so that Muting disappears from the screen (see page 44).
❏
Make sure the Speaker option is set to On in the Audio setting (see page 67).
❏
Make sure the MTS option is set to Stereo or Mono (see page 67).
❏
When the HDMI IN input is in use, surround sound, such as AC-3 and DTS,
cannot be input. Change the sound setting for the external input device to Linear
PCM.
❏
Communication problems may occur if infrared communication equipment (e.g.,
infrared cordless headphones) is used near the TV. Use headphones other than
infrared cordless headphones. Also, if you use infrared communication equipment
other than infrared cordless headphones, move the infrared transceiver away from
the TV until the noise is eliminated, or move the transmitter and receiver of the
infrared communication equipment closer together.
❏
Increase the volume of the cable box using the cable box's remote control. Then
press TV(FUNCTION) once (the TV indicator lights up) and adjust the TV's
volume.
❏
The TV's audio might be set to Auto SAP or Mono, when it might be better set to
Stereo. In the Audio setting (see page 67), set the MTS setting to Stereo. If
already set to Stereo, switch to Mono (which may reduce background noise
during weak stereo broadcasts).
❏
If the Speaker option is set to Off and the Audio Out option is set to Fixed (in
order to output the sound to your audio system), use your audio receiver to adjust
the sound (see page 67). Or, to use the TV remote control, set the Audio Out
option to Variable.
❏
To turn on the TV speakers, set the Speaker option to On (see page 67).
