      Severe hum or noise from your Sony Stereo Receiver can stem from several factors. First, ensure that all speakers and components are securely connected. Check that connecting cords are away from transformers, motors, TVs, or fluorescent lights (at least 3 meters away). Try moving your TV away from the audio components. Finally, clean the plugs and jacks with a cloth slightly moistened with alcohol.

    What to do if radio stations cannot be tuned in on my Sony HT-DDW840 Stereo Receiver?
    • C
      Colin BakerAug 23, 2025
      If you are having trouble tuning into radio stations on your Sony Stereo Receiver, verify that you have selected AV2 as the command mode. Ensure the antennas are securely connected; adjust them or connect an external antenna if needed. If tuning with automatic tuning, the signal strength may be too weak, so try direct tuning. When using direct tuning for AM stations, make sure the tuning interval is set correctly. If tuning by scanning preset stations, preset the stations if none are stored or have been cleared. Finally, press DISPLAY to show the frequency in the display.

      If there is no sound from one of the front speakers connected to your Sony Stereo Receiver, connect a pair of headphones to the PHONES jack to verify if sound is output. If both channels work through the headphones, the front speaker may not be correctly connected to the receiver. Check the connection of the front speaker that isn't producing sound.

      To improve poor FM reception on your Sony Stereo Receiver, use a 75-ohm coaxial cable (not supplied) to connect the receiver to an outdoor FM antenna. If connecting to an outdoor antenna, ground it against lightning, but do not connect the ground wire to a gas pipe to prevent a gas explosion.
