Symptom Remedy
No sound is output when an input
source is selected.
No sound output from the front
speakers. • Check the volume, mute setting (press MUTE) and speaker setting (press SPEAKERS).
• Make sure the correct input source is selected.
• Check that the MCACC setup microphone is disconnected.
• Make sure the correct input signal is selected (press
SIGNAL SELECT). Note that when PCM is selected,
you won’t be able to hear any other signal format.
• Check that the source component is connected properly (see
Connecting your equipment on page 12).
• Check that the speakers are connected properly (see Connecting the speakers on page 19).
No sound from the surround or
center speakers. • Check that the Stereo listening mode or the Front Stage Surround Advance mode isn’t selected; select
one of the surround listening modes (see
Listening in surround sound on page 28).
• Check that the surround/center speakers are not set to NO (see Speaker Setting on page 50).
• Check the channel level settings (see Channel Level on page 51).
• Check the speaker connections (see Connecting the speakers on page 19).
No sound from surround back
speakers. • Check that the surround back speakers are set to LARGE or SMALL (see Speaker Setting on page 50).
• Make sure surround back processing is set to SBch ON (see Using surround back channel processing on
page 31).
• If the source is Dolby Surround EX or DTS-ES with no flag to indicate 6.1 compatibility, then with surround
back processing set to
SBch Auto, there will be no sound from the surround back speakers. In this case,
set to SBch ON (see Using surround back channel processing on page 31).
• If the source does not have 6.1 playback channels, make sure that surround back processing is set to SBch
ON and a surround mode is selected (see Listening in surround sound on page 28).
• Check the speaker connections (see
Connecting the speakers on page 19). If only one surround back
speaker is connected, make sure it’s connected to the left channel speaker terminal.
No sound from subwoofer. • Check that the subwoofer is connected properly, switched on and the volume turned up.
• If your subwoofer has a sleep function, make sure it is switched off.
• Make sure that the Subwoofer setting is
YES or PLUS (see Speaker Setting on page 50).
• The crossover frequency may be set too low; try setting it higher to match the characteristics of your other
speakers (see
Speaker Setting on page 50).
• If there is very little low frequency information in the source material, change your speaker settings to
Front:
SMALL / Subwoofer: YES, or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on page 50).
• Check that the LFE channel is not set to OFF, or a very quiet setting (see Setting the Audio options on
page 70).
• Check the speaker level settings (see
Channel Level on page 51).
No sound from one speaker. • Check the speaker connection (see Connecting the speakers on page 19).
• Check the speaker level settings (see Channel Level on page 51).
• Check that the speaker hasn’t been set to NO (see Speaker Setting on page 50).
• The channel may not be recorded in the source. By using one of the advanced effect listening mode, you
may be able to create the missing channel (see
Listening in surround sound on page 28).
Sound is produced from analog
components, but not from digital
ones (DVD, LD, CD-ROM etc.). • Check that the input signal type is set to DIGITAL (see Choosing the input signal on page 31).
• Make sure that the digital input is assigned correctly for the input jack the component is connected to
(see
The Input Setup menu on page 66).
• Check the digital output settings on the source component.
• If the source component has a digital volume control, make sure this is not turned down.
• Make sure that the multichannel analog inputs are not selected. Select any other input source.
No sound is output or a noise is
output when Dolby Digital/DTS
software is played back. • Check that your DVD player is compatible with Dolby Digital/DTS discs.
• Check the digital output settings of your DVD player. Make sure that the DTS signal output is set to On.
• If the source component has a digital volume control, make sure this is not turned down.
No sound when using the System
Setup or Status menu. • If the HDMI input source is selected, sound is muted until exiting either menu.
• If sound is muted in the sub zone (
ZONE 2), it will be restored after exiting the System Setup menu.
