To perform a factory reset on the Sony STR-DA3700ES, turn off the receiver. Then, press and hold the 'Power' button while simultaneously pressing the 'Tone' button until "CLEARING" appears on the display. Release the buttons and the receiver will reset to factory settings.
First, ensure that all speaker wires are properly connected. Check that the receiver is set to the correct input and the volume is turned up. Verify that the 'Mute' function is not activated. If the issue persists, try using a different audio source or cable to troubleshoot the problem.
To update the firmware, connect the receiver to your network. Navigate to the 'Home' menu, select 'Settings', then 'Network Update'. Follow the on-screen instructions to download and install the latest firmware. Ensure the network connection is stable during the update process.
Connect the receiver to your TV using an HDMI cable. Use the HDMI OUT port on the receiver and connect it to an HDMI IN port on the TV. Set the TV to the correct HDMI input source. For optimal sound, enable HDMI Control (BRAVIA Sync) in the receiver settings.
Ensure the receiver is within range of your router and no obstructions are blocking the signal. Check that the network settings on the receiver match those of your home network. Restart both the receiver and the router. If problems persist, try a wired Ethernet connection for improved stability.
Use the Automatic Calibration feature by connecting the supplied calibration microphone to the receiver. Place the microphone at your listening position and select 'Home' > 'Settings' > 'Auto Calibration'. Follow the on-screen prompts to perform the calibration.
Yes, you can stream music from your smartphone using DLNA or AirPlay. Ensure the receiver and the smartphone are on the same network. Use a compatible app to stream via DLNA, or enable AirPlay on your iOS device to stream music directly.
Connect additional speakers to the Zone 2 or Zone 3 outputs on the receiver. In the 'Home' menu, navigate to 'Settings', then 'Zone Controls'. Configure the desired audio source and volume level for each zone. Ensure the zones you want to use are powered on.
Ensure the receiver is placed in a well-ventilated area and that vents are not blocked. Avoid stacking other electronic devices on top of the receiver. If overheating continues, consider using an external fan or cooling system to improve airflow.
Remove the batteries from the remote control, press all buttons to discharge any residual power, then reinsert the batteries. If this does not work, replace the batteries with new ones. Ensure the remote is pointed directly at the receiver during operation.
