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.
To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/STANDBY] button. �Clear� will appear on the display and the AV receiver will enter Standby mode.
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.
