To connect your Sony STR-DH520 to a TV, use an HDMI cable. Connect one end to the HDMI OUT jack on the receiver and the other end to an HDMI input on your TV. Ensure the TV is set to the correct HDMI input channel.
Check that all speaker wires are properly connected to the receiver and speakers. Ensure the receiver is set to the correct input and that the volume is not muted. Also, verify that the speakers are not damaged.
To perform a factory reset, turn off the receiver. Then, while holding down the "Power" button, press the "Power" button on the remote control. The display will show "CLEARING," indicating the reset is in progress. Release the buttons once "CLEARED" appears.
The Sony STR-DH520 does not have built-in Bluetooth capability. To use Bluetooth, you will need to connect a Bluetooth adapter to one of the audio input jacks.
The ideal speaker configuration for surround sound with the Sony STR-DH520 is 5.1. This includes two front speakers, one center speaker, two surround speakers, and one subwoofer. Adjust the speaker settings on the receiver accordingly.
The Sony STR-DH520 does not support firmware updates via USB or online. It is advised to check the Sony support website for any available updates or instructions specific to your receiver model.
To switch between audio modes on the Sony STR-DH520, press the "Sound Field" button on the remote or the receiver until you reach the desired mode, such as "Movie," "Music," or "Game."
Ensure that the receiver has proper ventilation and is not enclosed in a tight space. Remove any obstructions around the vents and consider using a cooling fan. If the problem persists, consult a professional technician.
To improve audio quality, ensure speakers are placed correctly and calibrate the speaker settings using the receiver's auto-calibration feature. High-quality cables and connections can also enhance sound performance.
Check the power connection and ensure the receiver is turned on. If the display is still not working, try a factory reset. If the problem persists, the display may need repair or replacement by a qualified technician.
