There is no sound from one of the front speakers. • Connect a pair of headphones to the PHONES jack to verify that sound is output from the headphones. If only one channel is output from the headphones, the component may not be connected to the receiver correctly. Check that all the cords are fully inserted into the jacks on both the receiver and the component. If both channels are output from the headphones, the front speaker may not be connected to the receiver correctly. Check the connection of the front speaker which is not outputting any sound. • Make sure you have connected both the L or R jack to an analog component and not just to either the L or R jack. Use a monaural-stereo cable (not supplied). There is no sound from analog 2 channel sources. • Check to make sure the selected audio (digital) input jack is not assigned to other inputs in "Input Assign" in the Input menu (page 98). There is no sound from digital sources (from COAXIAL or OPTICAL input jack). • Check that the INPUT MODE is set to "AUTO" (page 97). • Check that the "Analog Direct" is not being used. • Check to make sure the selected audio (digital) input jack is not assigned to other inputs in "Input Assign" in the Input menu (page 98). The left and right sounds are unbalanced or reversed. • Check that the speakers and components are connected correctly and securely. • Adjust the balance parameters using the Speaker setting menu in GUI menu. There is severe hum or noise. • Check that the speakers and components are connected securely. • Check that the connecting cords are away from a transformer or motor, and at least 10 feet (3 meters) away from a TV set or fluorescent light. • Move your TV away from the audio components. • Make sure you have grounded the U SIGNAL GND terminal (only when a turntable is connected). • The plugs and jacks are dirty. Wipe them with a cloth slightly moistened with alcohol. There is no sound, or only a very lowlevel sound is heard from the center/ surround/surround back speakers. • Select a "Cinema Studio EX" mode (page 64). • Adjust the speaker level (page 66). There is no sound from the subwoofer. • Check that the subwoofer is connected correctly and securely. • Make sure you have turned on your speaker. • When all speakers are set to "LARGE" and "Neo:6 Cinema", or "Neo:6 Music" is selected, there is no sound from the subwoofer.
