Question 3

Why does my ONKYO TX-NR717 receiver connected to the 'Main' output not display anything on my TV?

Accepted Answer

If your ONKYO TX-NR717 receiver is not producing any image on your TV through the HDMI Main output, start by checking the following items in this order:

1. Check the physical connections

Make sure the HDMI cable is fully inserted into the HDMI OUT MAIN output of the receiver and into the HDMI input of your TV. Also, check that the cable is not damaged by testing it with another device if possible.
Ensure that your TV is set to the HDMI input corresponding to where the TX-NR717 is connected (use the TV remote to select the correct input).

2. Check the receiver's Screen Output setting

Press HOME on the TX-NR717 remote to access the setup menu.
Go to Input/Output Assignment, then Screen Output.
Check that this setting is set to Main (since your TV is connected to the HDMI OUT MAIN output).
If this setting was set to Sub or Both, change it to Main and confirm.

3. Check the resolution settings

In the Input/Output Assignment menu, check the Resolution setting.
If your TV does not recognize the 4K or 1080p/24 resolution, select a lower resolution such as 1080p/60 or 720p/60.
Avoid the 4K Upscaling setting if your TV does not support 4K, as this may prevent display on certain models.

4. Check HDCP compatibility

The TX-NR717 uses the HDCP protocol to protect content. Only HDCP-compatible devices can display images.
If your TV is not HDCP compatible or if you are using a DVI/HDMI adapter, the image may not display.
Test with an HDCP-compatible device to verify that the receiver is functioning correctly.

5. Completely restart the system

Turn off the TX-NR717 and your TV using their respective power buttons.
Completely unplug the receiver from its power source for 30 seconds.
Plug it back in and turn it on, then power on the TV and select the correct HDMI input again.

If after these checks the screen remains black, try connecting your video source (Blu-ray player, satellite box, etc.) directly to the TV to confirm that the TV is working. If this confirms that only the TX-NR717 is having issues, consult an authorized Onkyo repair technician, as there may be a fault with the HDMI OUT MAIN port of the receiver.

Question 4

Why is there no sound when I use headphones with the ONKYO TX-NR717 receiver?

Accepted Answer

If you cannot hear sound with your headphones on the ONKYO TX-NR717 receiver, here are the checks to perform in order.

First, check the physical connection. Make sure your stereo headphones are properly plugged into the PHONES (6.3 mm) jack located at the front of the receiver. A light indicator should illuminate when the headphone plug is inserted. If you do not see this indicator, the jack is not properly connected. Also check the condition of the cable and the headphone plug, which may be damaged.

Lower the volume before plugging in the headphones. The manual explicitly recommends reducing the volume before each headphone connection to avoid sound spikes. Ensure that the receiver's volume is not at 0 or muted (check the front display for the volume level). If your headphones have an independent volume control, also check its setting.

Important: known issue with USB devices. If you have connected an iPod or iPhone to the USB port of the receiver, no sound will be produced through the headphones with this setup. Disconnect the mobile device from the USB port and use a standard audio input (RCA plugs, optical, etc.) to restore sound to the headphones.

Check the audio settings of the receiver. When you plug in the headphones, the listening mode automatically changes to Stereo (unless it was already set to Stereo, Mono, Direct, or Pure Audio). If sound still does not return, access the setup menu to adjust the “Headphone Level” setting, which can be set from -12 dB to +12 dB. If it is at the minimum (-12 dB), increase it by going through the HOME > Setup > Audio Settings > Headphone Level menu.

Remember that some audio functions do not work with headphones. The Audyssey 2EQ settings and some other audio processing parameters are automatically disabled when headphones are plugged in. This is normal and does not cause a loss of sound. The main speakers are also disabled when the headphones are connected (zones 2 and 3, if you are using them, remain active).

If none of these solutions work, try another pair of headphones to check that the problem does not come from the headphones themselves. Also consult an authorized technician if the problem persists, as this may indicate a fault with the PHONES jack of the receiver.

Question 9

What does the display 'VCR MONO' mean on the ONKYO HT-R380 receiver and how can I resolve the associated lack of sound?

Accepted Answer

The display 'VCR MONO' on your ONKYO HT-R380 receiver means that the VCR/DVR input is currently selected and that the Mono listening mode is activated simultaneously. The Mono mode is a valid listening mode, intended to reproduce monaural audio content, including older movies or mono recordings. However, when this mode is active, some speakers (surround and center) intentionally do not produce sound, which can give the impression of a general audio absence.

The lack of sound you are experiencing may have two origins: either the Mono mode itself, which disables certain channels, or a connection or configuration issue. The first step is to change the listening mode. Press one of the listening mode buttons on the front panel or the remote control (MOVIE/TV, MUSIC, GAME, or LISTENING MODE) to switch from Mono mode to another mode like Stereo or a surround mode (Dolby Digital, DTS, etc.). Use the MOVIE/TV button if you are watching a video, or MUSIC if you are listening to music. The display should change and you should regain sound.

If changing the listening mode does not bring sound, then check the physical connections. Ensure that the RCA audio cables (red and white) connecting your VCR/DVR device to the receiver are properly plugged into the VCR/DVR input of the HT-R380. The cables should be securely inserted into the jacks. Also, check that the source device (VCR, DVD player, etc.) is powered on and is outputting sound to its own audio output.

Next, test the audio source itself. Connect the VCR/DVR device to another device (a TV, a portable speaker) to confirm that the device is indeed producing sound. This will help you determine if the problem lies with the receiver or the source. In the meantime, on the receiver, check that the volume is not at minimum or muted. Look at the front panel to see if the MUTING indicator is flashing (in which case the receiver is muted). If so, press the MUTING button to restore sound.

If you have mistakenly selected another input source (TV/CD, GAME), use the buttons on the front panel to return to the VCR/DVR input. Press the VCR/DVR button on the front panel of the receiver to display 'VCR/DVR' on the screen and select this input. You can also check that the speakers A or B are activated by looking at the indicators on the front panel: at least the SPEAKERS A indicator must be lit for sound to be output.

If sound continues to be absent after these checks, access the receiver's setup menus via the SETUP button and verify that the speaker configuration is correct (the speakers should not all be set to 'None' or 'No'). You can also try another source (TV/CD or GAME) connected to the receiver to see if the problem is specific to the VCR/DVR input. As a last resort, consult ONKYO customer service, as a hardware fault on the inputs or the amplifier could be the cause.

Unplugging your ONKYO HT-R380 amplifier for several hours does not reset the device's settings. This action simply cuts off the power supply and causes a complete shutdown, but it does not restore the settings to their factory state.

To perform a complete reset of the ONKYO HT-R380, it is necessary to use the specific procedure provided by the manufacturer, usually accessible through the setup menu or a dedicated button. This method allows you to restore the default settings and resolve certain issues related to the settings.

In summary:

Unplugging the device: Complete shutdown, but settings remain unchanged.
Reset via menu or button: Restores factory settings.

It is therefore recommended to follow the official procedure to reset your amplifier and not to rely on a prolonged power cut.
