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. 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 receiver and all components are turned on. • Check that MASTER VOLUME control is not set at -∞ dB. Try to set it at about -40 dB. • Check that SPEAKERS (OFF/A/B/A+B) is not set to OFF (page 44). • Press MUTING on the remote to cancel the muting function. • Check that you have selected the correct component with INPUT SELECTOR. • Check that headphones are not connected. • When only a very low-level sound is heard, check to see if NIGHT MODE is activated (page 71). • 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 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 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). However, there will be no sound from the center speaker when a sound field (Pro Logic, etc.) is selected. When the center speaker is not connected, sound is output only from the front left/right speakers. 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 not set to "Analog" (page 97). • Check that the "2ch 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). 136GB
