Troubleshooting
If you have any trouble using the AV receiver, look for a solution in this section. If you can�t resolve the issue yourself, contact your Onkyo dealer. If you can�t resolve the issue yourself, try resetting the AV receiver before contacting your Onkyo dealer.

ON/STANDBY

� Check the volume (page 47). The AV receiver is designed for home theater enjoyment and has a wide volume range for precise adjustment. � If the MUTING indicator is �ashing on the display, press the remote controller�s [MUTING] button to unmute the AV receiver (page 48). � While a pair of headphones is connected to the PHONES jack, no sound is output by the main room speakers (page 49). � Check the digital audio output settings 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. If your turntable doesn�t have a phono preamp built-in, you must connect one between it and the AV receiver. If your turntable uses an MC cartridge, you must connect an MC head amp, or an MC transformer and a phono preamp. Check the speaker settings (pages 77�81). If the digital signal format is set to PCM or DTS, set it to Auto (page 50). If there�s no sound from a DVD player connected to an HDMI IN, check the DVD player�s output settings, and be sure to select a compatible audio format.
