Notice to Owners of STR-DG820 Multichannel A/V Receiver


    Under certain circumstances, when the BRAVIA® Sync feature is activated on both your Sony television and your STR-DG820 A/V Receiver or the HDMI control feature is activated on a non-Sony television, the volume level may suddenly increase above the maximum level on your receiver; otherwise, this issue does not affect the overall usability of your receiver.

    This issue is caused by a problem with the receiver’s firmware. In order to address this issue, you need to send your receiver in to Sony for a firmware update.

    To ensure customer satisfaction, Sony will provide a free repair service when this symptom occurs within certain units covered by the serial numbers indicated in the serial number validation box below.

    We apologize for any inconvenience this may cause and your kind understanding and cooperation would be much appreciated.
