Troubleshooting—Continued

There’s no sound with a certain signal format?

•Check the input signal format setting. Depending on the input source, you can select Auto, Multich, Ana- log, DTS, or PCM (page 51).

•Check the digital audio output setting on the source component. On some games consoles, such as those that play DVDs, 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 42).

Can’t select the DTS-ES Discrete/Matrix or THX Surround EX listening modes?

•These modes cannot be selected when no surround back speakers are connected.

The volume won’t go up to 79?

•When the levels of all speakers have been calibrated (page 30), 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 44).

The DVD multichannel input doesn’t work?

•Check the DVD MULTI CH IN connections (page 24).

•Set the audio input signal format to Multich (page 51).

About DTS signals

•When DTS playback finishes and the DTS bitstream stops, the TX-L55 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, because the TX-L55 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 playback.

•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 TX-L55. This is usually because the DTS bitstream has been processed (e.g., output level, sampling rate, or fre- quency response changed) and the TX-L55 doesn’t recognize it as a genuine DTS signal. In such cases, you may hear noise.

•When playing DTS material, using the pause, fast for- ward, or fast reverse function on your player may pro- duce a short audible noise. This is not a malfunction.

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.

•The TX-L55 doesn’t convert between video formats. It works as a video signal switcher. Composite video input signals are output only by the composite video output. S-Video input signals are output only by the S-Video output. And component video input signals are output only by the component video outputs.

•On your TV, make sure that the video input to which the TX-L55 is connected is selected.

Tuner

Reception is noisy, FM stereo reception is noisy, or the FM STEREO indicator doesn’t appear?

•Relocate your antenna.

•Move the TX-L55 away from your TV or computer.

•Try using the AUTO FM mode (page 36).

•Passing cars and airplanes can cause interference.

•Concrete walls weaken radio signals.

•If none of the above improves reception, install an out- door antenna.

Remote Controller

The remote controller doesn’t work?

•Make sure that the batteries are installed with the cor- rect polarity (page 7).

•Install new batteries. Don’t mix different types of bat- teries or old and new batteries (page 7).

•Make sure that the remote controller is not too far away from the TX-L55, and that there’s no obstruction between the remote controller and the TX-L55’s remote control sensor (page 7).
