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. General The receiver is turned off automatically. • "Auto Standby" is set to "ON" (page 121). • The Sleep Timer function is working (page 59). 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 to "VOL MIN". • Check that the SPEAKERS is not set to "SPK OFF" (page 42). • Check that headphones are not connected to the receiver or S-AIR surround amplifier. • Press MUTING (RM-AAP055 only) or (RM-AAP056 only) on the remote to cancel the muting function. • Check that you have selected the correct component with the input buttons (page 54). • Check to see if NIGHT MODE is activated (page 77). • 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. • Set the INPUT MODE to "AUTO" (page 103). 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 to both the L and R jacks of an analog component, and not only to either the L or R jack. Use an audio cord (not supplied). However, there will be no sound from the center speaker when a sound field (2ch Stereo, 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 that the selected digital audio input jack is not assigned to other inputs in "Input Assign" in the Input Option menu (page 104). continued 137GB Additional Information
