Onkyo TX-NR905 instruction manual 132, Troubleshooting

Troubleshooting—Continued

•Check the Speaker Configuration (page 94).

•While Powered Zone 2 is being used, playback in the main room is reduced to 5.1-channels and the sur- round back speakers produce no sound (page 119).

The subwoofer produces no sound

•If the source material contains no audio in the LFE channel, the subwoofer produces no sound.

•Check the Speaker Configuration (page 94).

The Zone 2/3 speakers produce no sound

•The Zone 2/3 speakers only output sources that are connected to an analog input. Check to see if the source component is connected to an analog input.

•Powered Zone 2 cannot be used if Speaker Type Front A is set to Bi-Amp or BTL, or Speaker Type Front B is set to Normal, Bi-Amp, or BTL (page 51).

There’s no sound with a certain signal format

•Check the digital audio output setting on the source component. On some game consoles, such as those that can play DVDs, the default setting is off.

•With some DVD-Video discs, you need to select an audio format from a menu or with the AUDIO button on your DVD player’s remote controller.

Can’t get 6.1- or 7.1-channel playback

•While Powered Zone 2 is being used, playback in the main room is reduced to 5.1-channels and the sur- round back speakers produce no sound (page 119).

Can’t select the Pure Audio listening mode

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

The volume cannot be set to +18 dB (99)

•Check to see if a maximum volume has been set (page 106).

•After the Automatic Speaker Setup function has been run, or the volume level of each individual speaker has been adjusted (pages 76 and 99), the maximum vol- ume may be reduced.

Noise can be heard

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on can degrade audio performance, so don’t use them.

•An audio cable may be picking up interference. Try repositioning your cables.

The Late Night function doesn’t work

• Make sure that the source is Dolby Digital (page 89).

The analog multichannel input doesn’t work

•Check the multichannel input connections (page 38).

•Make sure that the multichannel input is assigned to the input selector (page 59).

•Make sure that the multichannel input is selected (page 78).

•Check the audio output settings on your DVD player.

About DTS signals

•When 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 mal- function.

•When DTS program material ends and the DTS bit- stream stops, the AV receiver remains in DTS listen- ing 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, as the AV receiver does not switch formats immediately, you may not hear any- thing, in which case you should stop your player for about 3 seconds, and then resume playback.

•With some CD players, you won’t be able to playback DTS material properly even though your player is con- nected to a digital input on the AV receiver. This is usually because the DTS bitstream has been processed (e.g., output level, sampling rate, or frequency response changed) and the AV receiver doesn’t recog- nize it as a genuine DTS signal. In such cases, you may hear noise.

The beginning of audio received by an HDMI IN can’t be heard

•Since it takes longer to identify the format of an HDMI signal than it does for other digital audio sig- nals, sound may not be output immediately.

Video

There’s no picture

•Make sure that all video connecting plugs are pushed in all the way (page 33).

•Make sure that each video component is properly con- nected.

•On your TV, make sure that the video input to which the AV receiver is connected is selected.

•While the Pure Audio listening mode is selected, the video circuitry is turned off and only the HDMI OUT outputs video signals.

•If your TV is connected to the HDMI output, set the HDMI Monitor setting to Main or Sub (page 52), and select “- - -” in the “HDMI Input Setup” on page 54 to watch composite video, S-Video, and component video sources.

•If your TV is connected to the COMPONENT VIDEO OUT, set the HDMI Monitor setting to No (page 52), and select “- - -” in the “Component Video Input Setup” on page 56 to watch composite video and S-Video sources.

•If the video source is connected to a component video input, your TV must be connected to the COMPO- NENT VIDEO OUT or HDMI OUT (page 34).

•If the video source is connected to an HDMI input, your TV must be connected to the HDMI OUT (page 34).
