Troubleshooting

If you experience any of the following difficulties while using the receiver, use this troubleshooting guide to help you remedy the problem. Should any problem persist, consult your nearest Sony dealer.

There is no sound no matter which component is selected.

•Check that both the receiver and all components are turned on.

•Check that the MASTER VOLUME control is not set at –∞dB.

•Check that the SPEAKERS is not set to “OFF” (page 51).

•Check that all speaker cords are connected correctly.

•Press MUTING on the remote to cancel the muting function.

There is no sound from a specific component.

•Check that the component is connected correctly to the audio input jacks for that component.

•Check that the cord(s) used for the connection is (are) fully inserted into the jacks on both the receiver and the component.

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 not connected only the L or R jack to a monaural component. Use a monaural- stereo cable (not supplied) and connect it to both the L and R jacks. However, there will be no sound from the center speaker when a sound field (PRO LOGIC, etc.) is selected. When the center speaker is set to “NO”, sound is output only from front L/R speakers.

There is no sound or only a very low-level sound is heard.

•Check that the speakers and components are connected securely.

•Check that you have selected the correct component with INPUT SELECTOR.

•Check that the SPEAKERS is not set to “OFF” (page 51).

•Check that the headphones are not connected.

•Press MUTING on the remote to cancel the muting function.

•The protective device on the receiver has been activated. Turn off the receiver, eliminate the short-circuit problem and turn on the power again.

There is no sound from analog 2 channel sources.

•Check that the DIGITAL ASSIGN function is not used to assign the audio input of other input to the selected input (page 37).

•Check that the INPUT MODE is not set to “COAXIAL FIXED” nor “OPTICAL FIXED” for the selected input (page 38).

•Check that the MULTI CH IN function is not selected.

There is no sound from digital sources (from COAXIAL or OPTICAL input jack).

•Check that the DIGITAL ASSIGN function is not used to assign the audio input of other input to the selected input (page 37).

•Check that the INPUT MODE is not set to “ANALOG 2CH FIXED” (page 38). Check that the INPUT MODE is not set to “COAXIAL FIXED” for the sources from OPTICAL input jack, nor set to “OPTICAL FIXED” for the sources from COAXIAL input jack.

•Check that the MULTI CH IN function is not selected.

The left and right sounds are unbalanced or reversed.

•Check that the speakers and components are connected correctly and securely.

•Adjust balance parameters in the LEVEL 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 3 meters away from a TV set or fluorescent light.
