Troubleshooting Guide

The Sun re TGR-401 is expertly designed and built to provide years of trouble-free performance. Most prob- lems that occur can usually be solved by checking your setup or making sure that the audio and video compo- nents connected to the TGR-401 are on and fully operational.

The following information will help you deal with common setup problems you may experience during normal use of your unit. If problems persist, contact your Sun re Dealer for help.

No sound from one or more speakers

Speaker cables may have come undone. Turn off your system and check the cables, and tighten the binding posts.

An audio cable may have an inter- nal break.

The volume level is low for the channels concerned. Recheck the level calibration (page 39).

The Mute switch is on.

The channel has not been turned on in the Speaker Size Menu (page 33).

The correct surround mode is not selected. (Some DVD discs are stereo only).

Note: In Source Direct mode, only the front left and right speakers are engaged. They must also be set to Large.

No subwoofer or poor output

The subwoofer’s ampli er is off, or its controls are set low.

Are all speakers set Large?

SUB is not switched on in the Speaker Size Menu (page 39).

Recheck the level calibration pro- cedure (page 39).

Adjust the Crossover and check Bass Management (page 39).

See page 51 to nd the best loca- tion for your subwoofer.

If the bass is weak during Dolby Digital or DTS playback, check the correct audio output is selected in your DVD menu, otherwise it may just play stereo into your TGR-401 and you won’t get the true LFE signal to the subwoofer.

Poor Tuning of Stations

The antenna may be incorrectly attached.

The station is not correctly tuned in, weak or off the air.

You can improve reception by us- ing external antennas. Some cable TV feeds also offer FM reception.

The same AM station can be heard at different frequencies

One wire of the AM loop antenna may not be connected.

A loop antenna is required for AM reception, as it forms part of the front-end tuned circuit.

Fully Automatic does not work

Make sure the Auto On mode is set to Y in the MAIN ZONE setup menu (page 35) and that each input is con gured for AUTO ON in their respective INPUTS menu (page 33).

In the INPUTS menu, also make sure each source is set to MAIN, and not M/Z2 or ZONE 2.

In order to automatically choose the new input source, this mode senses the following active signals: Left audio signals, Video signals, Digital signals

Note that LD or DVD players sometimes put out digital signals even when the disc is paused or stopped. Make sure that any sources are turned off when not in use.

If a source is always active, the automatic operation may return to that input as the analog audio varies. In this case, you should try and turn off any unused sources, or turn off the automatic mode.

APPENDIX

If you are listening to a mono source, make sure it connects to a left input, or use a “Y” cord to feed both left and right inputs.

Certain inputs cannot be se- lected

Check the INPUTS menu of the OSD (page 33), and make sure that the input has not been dis- abled in that particular Zone.

No TV picture

Make sure that the video input of your TV monitor is connected to the Main monitor output on the TGR-401 rear panel.

Check the video input is correct in the INPUTS menu of the OSD (page 33). Select the type of video input you have connected.

Check that your TV monitor is selecting it’s correct video input.

Check the video connection from your selected source component into the TGR-401.

If in doubt, try connecting the video output from your source directly to your TV monitor. This will help you narrow down the problem.

Do not connect more than one type of video connection to the same input. Choose only the highest quality video type.

No Sonic Holography Effect

It is essential that your front speak- ers are positioned correctly. See page 50.

Sonic Holography is most ef- fective in 2-channel operation. It gives a more accurate perception of the position of musicians and sound effects. The results may be masked if you are using it in a sur- round mode.
