Troubleshooting

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

Audio

There is no sound, no matter which component is selected, or only a very low-level sound is heard.

•Check that the speakers and components are connected securely.

•Check that all speaker cords are connected correctly.

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

•Check that VOLUME control is not set at

–∞dB.

•Check that SPEAKERS (OFF/A/B/A+B) is not set to “OFF” (page 11).

•Press MUTING to cancel the muting function.

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

•Check that headphones are not connected.

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

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 amplifier and the component.

There is no sound from one of the 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 amplifier correctly. Check that all the cords are fully inserted into the jacks on both the amplifier and the component. If both channels are output from the headphones, the speaker may not be connected to the amplifier correctly. Check the connection of the 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).

The left and right sounds are unbalanced or reversed.

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

•Adjust the balance parameters by pressing BALANCE on the remote.

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 m 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.

Recording cannot be carried out.

•Check that the components are connected correctly (page 7, 8).

•Select the source component using INPUT SELECTOR (page 11, 12).
