Troubleshooting

Audio

There is no sound, or it is very quiet

 Make sure that the proper input source is selected.

 Make sure that connecting plugs are pushed in all the way.

 Make sure that the inputs and outputs of all components are connected properly.

 Make sure that the polarity +/– of the speaker cables is correct, and that no bare wires are in contact with the metal part of speaker terminals.

 Make sure that the input source is properly selected.

 Make sure that the speaker cables are not shorting.

 Check the volume. The volume level is adjustable between Min, 1 to 99, Max (100). It is normal that the unit volume level is set up to 60 or around.

 If the MUTING indicator on the display flashes, press MUTING on the remote controller to unmute the unit.

 While headphones are connected to the PHONES jack, no sound is output from the speakers.

 If there is no sound from a BD/DVD player connected to an HDMI IN, check the BD/DVD player’s output settings, and be sure to select a supported audio format.

 Check the digital audio output setting on the connected component. On some game consoles, such as those that support DVD, the default setting is off.

 With some DVD-Video discs, you need to select an audio output format from a menu.

 If your turntable uses an MC cartridge, you must connect an MC head amp, or an MC transformer.

 Make sure that none of the connecting cables are bent, twisted, or damaged.

 Not all listening modes use all speakers.

 Perform the automatic speaker setup again or manually set the presence or absence, crossover frequency, distance and level of each speaker.

 Make sure that the speaker setup microphone is not still connected.

 Set to "Off" if "Audio Selector" - "Fixed Mode" is set to "PCM" or "DTS".

Only the front speakers produce sound

 When the Stereo or Mono listening mode is selected, only the front speakers and subwoofer produce sound.

 Make sure the speakers are configured correctly.

Only the center speaker produces sound

 If you use the Dolby Surround listening mode with a mono source, such as an AM radio station or mono TV program, the sound is concentrated in the center speaker.

 Make sure the speakers are configured correctly.

The surround speakers produce no sound

 When the T-D (Theater-Dimensional), Stereo or Mono listening mode is selected, the surround speakers produce no sound.

 Depending on the source and current listening mode, not much sound may be produced by the surround speakers. Try selecting another listening mode.

 Make sure the speakers are configured correctly.

The center speaker produces no sound

 When the Stereo or Mono listening mode is selected, the center speaker produces no sound.

 Make sure the speakers are configured correctly.

There is no sound from surround back speakers, height speakers or front wide speaker.

 Depending on the source or current listening mode, not much sound may be output from speakers. Try selecting another listening mode.

 Make sure the settings for the speakers are made correctly.

The subwoofer produces no sound

 When you play source material that contains no information in the LFE channel, the subwoofer produces no sound.

 Make sure the speakers are configured correctly.

There is no sound with a certain signal format

 When listening to Dolby Digital and/or DTS sound, digital connection is necessary.

 Check the digital input terminal setting. If the connection is different from the default, re-setting is necessary.

 Check the digital audio output setting on the connected component. On some game consoles, such as those that support DVD, the default setting is OFF.

There is no sound with Dolby Atmos signal format

 Make sure the surround back speakers, the height speakers or wide speakers are connected and configured as connected in the "Speaker Configuration".

 Make sure the input signal is the Dolby Atmos format.

Cannot select the Pure Audio listening mode

 The Pure Audio listening mode cannot be selected while Zone 2/Zone 3 is on.

Cannot select a desired listening mode

 Depending on the connecting status of the speaker, some listening modes may not be selected. Check the details in "Using the Listening Modes" section.

The speaker volume cannot be set as required

 Check to see if a maximum volume has been set.

Noise can be heard

 Using cable ties to bundle analog audio (RCA) cables with power cords, speaker cables, etc. may degrade the audio performance, so refrain from doing it.

 An analog audio (RCA) cable may be picking up interference. Try repositioning your cables.

The Late Night function does not work

 Make sure the source material is Dolby Digital, Dolby Digital Plus, or Dolby TrueHD.

About DTS signals

 When DTS program material ends and the DTS bitstream stops, the unit remains in DTS listening mode and the dts indicator remains on. This is to prevent noise when you use the pause, fast forward, or fast reverse function on your player. If you switch your player from DTS to PCM, you may not hear any sound because the unit does not switch formats immediately. In such case, you should stop your player for about 3 seconds and then resume playback.

 With some CD and LD players, you will not be able to playback DTS material properly even though your player is connected to a digital input on the unit. This is usually because the DTS bitstream has been processed (e.g., output level, sampling rate, or frequency response changed) and the unit does not recognize it as a genuine DTS signal. In such cases, you may hear noise.

 Playing DTS program material, using the pause, fast forward, or fast reverse function on your player may produce a short audible noise. This is not a malfunction.

The beginning of audio received by an HDMI IN cannot be heard

 Since it takes longer to identify the format of an HDMI signal than it does for other digital audio signals, audio output may not start immediately.
