Hi jkimmell,
If your
Sunfire Receiver has no sound from one or more speakers, it is often caused by a connection issue. There are several ways on how to correct this problem, either you check if speaker cables may have undone or recheck the calibration procedure. Here are additional troubleshooting that you may use, please follow the steps below.
1. Speaker cables may have come undone. Turn off the system and check the cables, and tighten the binding posts.
2. An audio cable may have an internal break.
3. The volume level is low for the channels concerned. Recheck the calibration procedure. Please click the link below for the manual and see page 40.
4. The channel has not been turned on in the Speaker size menu. Please see page 38.
5. The correct sound mode is not selected. ( Some DVD discs are stereo only ).
6. Note. In the source direct mode, only the front left and right speakers are engaged. They must also be set to large.
If this does not work, please try the reset procedure.
Note: the receiver will be reset to the factory defaults, and will clear all memory. All your stored OSD settings and Tuner preset will be erased.
1. Press the power button to turn off the unit. You may also turn it off from the wall for a moment.
2. Press and continue to hold down the front panel Power button and Tone DOWN button at the same time.
3. The Receiver will power on and cycle through the display. Keep holding the buttons down until " Resetting to Factory Defaults " appears in the front panel display.
4. When the receiver has been reset, it will shut off.
5. Turn the receiver back on and it will go to the default screen. It has now been reset.
5. If the receiver has to be reset regularly, you should invest in a good quality AC line conditioner.
