To perform a factory reset, turn off the receiver, press and hold the "POWER" button, and then press and hold the "TONE MODE" and "TONE CONTROL" buttons simultaneously. Release the buttons when "CLEARED" appears on the display.
First, check that the speakers are properly connected. Ensure the receiver is set to the correct input source. Verify that the "MUTING" function is not activated and the volume is not set to "MIN".
To update the firmware, download the latest firmware from Sony's official website onto a USB drive. Insert the USB drive into the receiver's USB port and follow the onscreen instructions to complete the update.
Use an HDMI cable to connect the HDMI OUT on the receiver to an HDMI IN on your TV. This ensures the best audio and video quality and allows the receiver to control the TV.

Use the built-in auto-calibration feature, which adjusts the speaker settings based on your room's acoustics. Further fine-tune settings manually through the receiver's menu.
Ensure the power cord is properly connected to an outlet. Check the circuit breaker and replace any blown fuses. Try a different power outlet to rule out an outlet issue.
