    Why is there no DTS sound from my Denon AVR-1707 Stereo Receiver?
    • S
      stacywheelerAug 25, 2025
      If you're not getting any DTS sound, first, make sure the DVD player’s audio output setting is set to bit stream, or make the DVD player’s default settings. Also, confirm that your DVD player is DTS-compatible; if not, use a DTS-compatible player. Lastly, check that the receiver's input setting is set to “AUTO” or “DTS,” not analog.

    What does it mean when the power indicator is blinking red on my Denon Stereo Receiver?
    • E
      Elizabeth WilsonSep 14, 2025
      If your Denon Stereo Receiver's power has turned off and the power indicator is blinking red, it indicates that the protection circuit has been activated. This could be due to a few reasons: * The unit's internal temperature may have risen. In this case, place the receiver in a well-ventilated area. * The core wires of the speaker cables might be touching each other or the receiver's rear panel. Inspect and correct all speaker cable connections. * The receiver might be malfunctioning.

    How to fix no display on monitor connected to Denon AVR-1707 Stereo Receiver?
    • S
      Scott YoungSep 3, 2025
      If nothing is displayed on the monitor, verify that the receiver's video output terminals and the monitor's input terminals are correctly connected. Also, ensure that the monitor's input setting is set to the correct terminals to which the video signals are connected. If you're using a player connected with a component terminal and a TV connected with a video (yellow) or S-Video terminal, note that down-conversion is not possible for progressive video signals; adjust the interlace settings on the player.
