Fix Onkyo Subwoofer Pre Out Not Working

Here, out stands for preamplification output. This is inserted in the subwoofer circuit. It helps add all kinds of channels to your room’s television. Sometimes you have to face the cause when your Onkyo subwoofer pre-out not working? Here are some simple steps to check and resolve the issue with the Onkyo subwoofer pre-out connection!

Why do you face the problem?

The problem itself is not so difficult to solve. It can be solved merely by a small number of steps. Only follow the steps mentioned in the article and hopefully, you will be able to solve the issue without any problems.

Check the power

Look at your speaker’s subwoofer connection to make sure you have power. If it is, try moving your device and speaker cables around to see if that fixes your issue.

If there’s no power to it at all, check your fuses or circuit breakers in your home and replace them if they need replacing.

They could also be tripped due to a power surge, so unplug everything and turn off all fuses or circuit breakers for five minutes before turning them back on again.

If the power is not proper even after you turn it back on again, then you need to follow the steps below.


Verify Connection

To fix the Onkyo subwoofer pre-out not working, first, unplug both ends of your speaker wire and check to see if any visible damage is present.
If it’s okay, verify that all wires are plugged into both ends and make sure they’re secure.
Also, be sure that both ends are properly connected to their correct jacks on your receiver by using a cable tester or checking each wire with an ohmmeter if you have one handy.
Lastly, double-check that there isn’t another jack where your subwoofer should be connected; some receivers come with extra inputs and can easily cause confusion for new users.

Do Not Check Speaker Wire

You may think it would be obvious to skip checking the speaker wire since you just verified its connection, but some people actually test them anyway after making sure they were plugged in correctly; no need to waste time doing something twice!

Reset the device

First, you need to make sure that your Onkyo Audio Device is connected and powered on. If it is not, try resetting or reconnecting your device. You can unplug your device for a few seconds and then plug it back in again.

Resetting your device will also help fix minor issues with connection issues. Here’s how

1) Unplug all cables from your Onkyo Receiver

2) Wait 10 seconds

3) Plug all cables back into your receiver

4) Power on your Receiver by pressing any button (don’t hold)

5) Wait 5-10 minutes while everything resets itself. Once it has finished resetting, power off and power on again.

This should fix most problems with no sound coming out of any speakers when using an HDMI connection.

Try different cable

Make sure you are using a high-quality cable on your subwoofer. Since different subwoofers have different outputs and inputs, we need to know what type of cable you are using in order to give you advice on whether or not it is defective.

If your cables aren’t working, try switching out your wires for new ones. If that doesn’t work, it may be a problem with your Onkyo subwoofer pre-out ports.

You can check them by unplugging your subwoofer from power and then plugging back in while watching your television screen.

The screen should display some sort of audio output option (this will vary depending on what kind of audio system you have).

If there is no sound coming from your television, then there might be an issue with either your Onkyo subwoofer pre-out ports or a bad connection between these ports and where they connect to inside your television set.

Unplug and Plug Back In

Most of these issues are power-related. If your speakers have a power light, check that to make sure it is on. Try plugging back in, or unplugging and replugging in your speakers.

Also, try resetting by turning it off for a minute and then turning it back on. This should do it if you had a loose connection with your power cord to fix the Onkyo subwoofer pre-out not working issue.

If you still do not get the issue resolved, you probably need to change your worn-out subwoofer, or you can try further fixes to make sure everything.

Pre-out Terminal issue

Fix Onkyo subwoofer pre-out terminal not working. There is a problem with your pre-out cable or input circuit board in your subwoofer. The repair of the Onkyo subwoofer pre-out terminal not working requires the replacement of both parts mentioned above.

The cost to fix it will be about $100 for parts and labor. But you can do it yourself if you have experience fixing electronics. You will need to purchase two new cables and solder them onto your existing ones.

After that, you’ll need to unsolder and remove your old ones from both ends and then put everything back together again.

An easy method to prove that is when you transfer the subwoofer cable from the pre-out and then transfer it to the tape-out section.
