Troubleshooting—Continued

The subwoofer produces no sound?

•When you play source material that contains no infor- mation in the LFE channel, the subwoofer produces no sound.

•Make sure the speakers are configured correctly (page 39).

There’s no sound with a certain signal format?

•Check the digital audio output setting on the con- nected device. On some games 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.

•Depending on the input signal, some listening modes cannot be selected (page 50).

Can’t get 5.1 playback?

•If the Zone 2 speakers are being used, you can use ste- reo sound in the main room.

The volume cannot be set to 99?

•When the levels of all speakers have been calibrated (page 42), the maximum volume setting may change.

Noise can be heard?

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so don’t do it.

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

The Late Night function doesn’t work?

•Make sure the source material is Dolby Digital (page 52).

The DVD analog multichannel input doesn’t work?

•Check the DVD analog multichannel input connec- tions (page 28).

•To select the DVD analog multichannel input, press the [Multi CH] input selector button.

•Check the audio output settings on your DVD player.

About DTS signals

•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, because the AV receiver does not switch formats immediately, you may not hear any sound, in which case you should stop your player for about three seconds, and then resume play- back.

•With some CD and LD players, you won’t be able to playback DTS material properly even though your player is connected 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 recognize it as a genuine DTS signal. In such cases, you may hear noise.

•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.

Video

There’s no picture?

•Make sure that all video connecting plugs are pushed in all the way (page 20).

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

•If your video component is connected to a component video input, your TV must be connected to the compo- nent video output (page 25).

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

The onscreen menus don’t appear?

•Make sure that the video settings are correct (page 38).

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

•Depending on the display device, when the “b. Scan Mode” setting on the “6-3. OSD Setup” menu is set to Non-Interlaced, the onscreen setup menus may not appear. If this happens, use the AV receiver’s display and change that setting to Interlaced.
