Question 1

How to resolve a sound buzzing issue on the ONKYO TX-SR875 AV receiver?

Accepted Answer

The buzzing sound on your ONKYO TX-SR875 AV receiver can have several causes. Here are some steps to follow to identify and resolve this issue:

1. Check the connections

Make sure all audio cables (HDMI, RCA, optical, etc.) are properly connected and in good condition.
Replace the cables if you suspect they are damaged or of poor quality.

2. Test different audio sources

Try connecting another source (Blu-ray player, console, etc.) to see if the buzzing persists.
If the problem goes away, it indicates that the original source is the cause.

3. Adjust the volume and audio settings

Lower the volume to see if the buzzing decreases, as a volume that is too high can cause distortions.
Check the audio settings in the receiver's menu, including sound processing modes, equalizer, or effects, and try disabling or adjusting them.

4. Keep electronic devices away

Electromagnetic interference can cause buzzing. Keep the receiver away from other electrical or wireless devices.

5. Restart and update

Turn off and then turn on the receiver to eliminate any potential temporary bug.
Check if a firmware update is available and proceed with installation if necessary.

By following these tips, you should be able to reduce or eliminate the buzzing sound on your ONKYO TX-SR875. If the problem persists, it may be a hardware defect requiring technical intervention.

Question 2

How to access the configuration menu of the ONKYO HT-R380 audio-video receiver?

Accepted Answer

To access the configuration menu of your ONKYO HT-R380 receiver, use the supplied remote control by following these precise steps:

Accessing the menu:

Press the RECEIVER button on the remote control, then press the SETUP button. The main configuration menu will appear.
Important: The configuration menus are only displayed on a television connected to the HDMI OUT output of the receiver. If your television is connected to the MONITOR OUT (composite) or COMPONENT VIDEO OUT, you must use the display of the receiver itself to change the settings.
The configuration menus also appear when there is no active video input, or when the video resolution is 480p, 576p, 720p, 1080i, or 1080p.

Navigation in the menu:

Use the A/Y buttons (up/down arrows) on the remote control to select a menu category from the ten available: HDMI Input, Component, Digital Audio, Sp Config (Speaker Configuration), Sp Distance (Speaker Distance), Level Cal (Level Calibration), Audio Adjust, Name Edit, Hardware, and HDMI Setup.
Press ENTER to confirm your selection and access the chosen category.
Use A/Y again to navigate between the options of the selected category.
Use the < > buttons (left/right arrows) to modify the parameter values.

Closing and navigation:

Press the SETUP button to close the configuration menu and return to the normal screen.
Press the RETURN button to return to the main menu from a sub-category.

The changes you make are saved automatically. This procedure allows you to fully customize the audio, video settings, and speaker adjustments of your HT-R380 according to your setup and preferences.

Question 3

Does unplugging the ONKYO HT-R380 amplifier for several hours reset its settings?

Accepted Answer

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.

Question 4

Why does my ONKYO TX-NR717 amplifier turn off and then immediately turn back on?

Accepted Answer

If your ONKYO TX-NR717 receiver turns off and then immediately turns back on, the problem is most likely due to the activation of the built-in protection circuit. This safety circuit automatically triggers in case of overheating, a short circuit at the speakers, or overload due to too low an impedance.

Checking the MUTING light: Before taking any action, observe the display screen of the TX-NR717. If the MUTING light is blinking, this indicates an attempt to activate the protection circuit. Simply press the MUTE button on the remote control to disable the mute and normalize operation. If no light is blinking, the complete protection circuit has been triggered, and you need to proceed to the following steps.

Reset procedure: Immediately unplug the power cord from the wall outlet. First, check that all speaker cables and input source cables (DVD, TV decoder, audio sources) are properly connected to their respective connectors. Make sure that the bare wires of the speaker cables are in good contact with the metal terminals of the speaker connectors. Leave the power cord unplugged for a complete 1 hour, then plug it back in and turn the device on. If the TX-NR717 turns off again, unplug the cord and immediately contact your ONKYO dealer.

Checking the speaker cables: This is the most common cause of the problem. Look at the display screen: if the message "CHECK SP WIRE" appears, it means there is a short circuit at the speaker connections. Ensure that the positive (+) and negative (-) wires of each speaker cable do not touch each other and are properly insulated. Also check the polarity: positive (+) terminals should connect only to positive (+) terminals, and negative (-) terminals only to negative (-) terminals. If you have reversed the polarity, correct it immediately.

Checking ventilation and impedance: Ensure that the receiver has adequate ventilation. Leave a free space of at least 20 cm above and on the sides of the device, and 10 cm at the back. The back of the furniture should be at least 10 cm from the wall. Clean the ventilation grilles. Additionally, check the impedance of your speakers: the TX-NR717 accepts speakers from 4 to 16 ohms. If a speaker has an impedance between 4 and 6 ohms, you must set the "Speaker Impedance" parameter to "4 ohms" in the Speaker Setup menu. If you use a lower impedance with high volume for an extended period, the protection circuit will intentionally activate.

If after these checks the problem persists, it may be an internal defect requiring professional technical intervention. Contact your authorized ONKYO dealer for repair.
