Why is my Denon AVR-1507 display lit but no sound is produced?

  Judith GarciaJul 26, 2025
  If your Denon Stereo Receiver display is lit but no sound is being produced, several factors could be at play. First, make sure the speaker cables are securely connected. Second, ensure the INPUT SELECTOR knob is in the correct position. Third, check that the volume control is not set to the minimum; turn it up to a suitable level. Also, verify that MUTING is switched off. Finally, if you're using a digital signal, ensure a digital signal input source is properly selected.

What to do if sound is only produced from the center speaker on my Denon Stereo Receiver?

  Daniel JohnsonAug 1, 2025
  If sound is only coming from the center speaker on your Denon Stereo Receiver, it might be because you're playing a monaural source (like TV or AM radio) in the STANDARD (Dolby/DTS Surround) mode. When playing monaural sources, try selecting a surround mode other than STANDARD (Dolby/DTS Surround) mode.

What to do if my Denon AVR-1507 Stereo Receiver power has turned off and the power indicator is blinking red?
- L
  Lisa DavisAug 6, 2025
  If the Denon Stereo Receiver's power indicator is blinking red and the power has turned off, this could be due to several reasons. First, the internal temperature of the unit may have risen, activating the protection circuit. Ensure the receiver is in a well-ventilated area. Second, the speaker cables' core wires might be touching each other or the receiver's rear panel, which also activates the protection circuit. Check all speaker cable connections. Finally, the receiver itself may be malfunctioning. In this case, turn off the power and contact a DENON customer service center.

  If nothing is displayed on the monitor connected to your Denon Stereo Receiver, first check that the receiver's video output terminals and the monitor's input terminals are correctly connected. If the connections are correct, then check that the monitor’s input setting is set to the terminals to which video signals are connected.

Why is no DTS sound produced by my Denon AVR-1507?
- R
  Richard BowenAug 19, 2025
  If your Denon Stereo Receiver isn't producing DTS sound, there are a few potential causes. First, check that your DVD player’s audio output setting is set to bit stream. If that’s not the issue, ensure your DVD player is DTS-compatible. Finally, verify that the receiver’s input setting is set to “AUTO” or “DTS.”
