Why doesn't my Denon AVR-1705 Receiver remote control work properly?
- C
  Christian WalterJul 26, 2025
  Several reasons could explain this. First, check the batteries and replace them if they're dead. Ensure you're not too far from the unit; move closer. Check for any obstructions between the remote and the receiver and remove them. Make sure you're pressing the correct button. Finally, verify that the batteries are inserted correctly, with the < and > ends properly aligned.

  Several factors might be at play. First, ensure the speaker cords are securely connected. Next, check the INPUT SELECTOR knob to ensure it’s in the correct position. Also, verify that the volume control isn't set to the minimum. It's also possible that MUTING is enabled, so switch it off. Finally, if you've selected a digital input, make sure digital signals are being input or that you've selected the correct input jacks.

  This issue is likely due to reversed connections. Check the left and right connections of both the speakers and the input/output cords to ensure they are correctly connected.

Why is the DISPLAY on my Denon AVR-1705 Receiver not displayed and the power indicator flashes rapidly?
- K
  Katrina NormanAug 15, 2025
  This issue may arise due to a short-circuit in the speaker terminals. To resolve this, switch off the power, properly connect the speakers, and then switch the power back on. Another potential cause is blocked ventilation holes. If this is the case, turn off the power, ensure adequate ventilation to cool down the unit, and then turn it back on. This issue can also happen if the unit is operating at continuous high power conditions with inadequate ventilation. Turn off the set’s power, then ventilate it well to cool it down. Once the set is cooled down, turn the power back on.
