Onn Subwoofer Not Working

Onn subwoofers offer high-quality audio equipment for home use at a very affordable price. Depending on the model, they feature Dolby Audio support and Bluetooth streaming, as well as the ability to connect using HDMI-ARC, HDMI, and optical inputs. They’re very easy to connect and pair with your other audio and video devices and can generally be set up in minutes. However, like all electronic devices, they can have issues. If your Onn subwoofer is not working, there are a few things you can do to troubleshoot, diagnose, and fix the problem.

When your Onn subwoofer isn’t working, make sure the outlet and power cord are functioning properly. If you’re using an extension cord or power strip with a breaker, check to make sure it hasn’t tripped.

A reset can help fix most minor issues with an Onn subwoofer. Here’s how to do it:

Turn off and unplug the subwoofer and soundbar for 60 seconds > plug them back in and turn them on. They should automatically connect when turned on after a reset, but if they don’t, you’ll have to pair them manually.

If the subwoofer and soundbar don’t automatically connect, you’ll have to reset them again and pair them manually. Here’s how:

After the reset, turn the subwoofer on and press the pairing button. The light should start blinking > turn on the sound bar using the remote and press and hold the dim button for about 5 seconds > press the plus and minus buttons on the bass to complete the pairing.

How To Pair An Onn Subwoofer

An Onn subwoofer and soundbar should pair automatically out of the box. However, if they don’t or the two lose connection, you can pair them manually after a reset.

To pair your Onn subwoofer with the sound bar, do the following:

Turn off and unplug both devices.
Wait about 60 seconds.
Plug the subwoofer in and turn it on.
Press and hold the mute button on the remote for seven seconds.
Turn on the soundbar.
Press and hold the pairing button on the subwoofer.

The LEDs on both the subwoofer and soundbar will flash until the connection is made. Once they’re paired, the lights will stop flashing and stay on.

If the subwoofer still doesn’t pair, reset the sound bar and start the process again. This time, turn off other wireless devices in the area that may be interfering with the signal.

Why Won’t Onn Subwoofer Connect To The Soundbar?

An Onn subwoofer can be connected to the soundbar either wirelessly using Bluetooth or via a hard wire. The hard wire option is more reliable and has better overall performance. You can do it with an HDMI or HDMI-ARC cable. However, many people prefer the cleaner look of a wireless setup.

Connecting your devices using Bluetooth is usually quick and easy to set up when everything is working correctly, but there can be issues, such as a loss of pairing. When this happens, a reset can usually help pair the devices.

When your Onn subwoofer isn’t connecting to the soundbar, it’s best to try a reset.

Switch off and unplug both the subwoofer and soundbar.
Wait about 60 seconds.
Plug both devices back in.
Turn on the subwoofer by pressing the power button.
Press the power button and then the start button on the remote. The soundbar should emit a tone to confirm it’s on.
Make sure the soundbar and subwoofer are close together (within 3 feet).
Use the remote to enable Bluetooth mode by pressing the Bluetooth button. The indicator light on the soundbar should slowly flash blue to confirm Bluetooth mode is active.
Alternatively, you can press the source button on the soundbar to enable Bluetooth mode.
Press the subwoofer Bluetooth pairing button and wait for the Bluetooth LED to stop flashing on the soundbar.

I sometimes have trouble making a Bluetooth connection when there are lots of Bluetooth devices in the room that can interfere with the signal. If you have a similar issue, turn off other devices or take them out of range while you make the pairing.

What To Do When Onn Subwoofer Won’t Turn On

Subwoofers are generally easy to use and set up fairly quickly. However, sometimes they have issues with connectivity and powering on. If your Onn subwoofer won’t turn on, here’s what you can do:

Check Power Source: First, switch off the power at the wall socket and plug the subwoofer into an alternative socket to rule out any issues with the power source.
Inspect Power Cable: If the subwoofer still won’t turn on, unplug it and carefully examine the power cable for any damage or fraying. Replace the cable if necessary.
Extension Cord: If you’re using an extension cord or power strip, check to make sure it’s working properly. Try plugging the device directly into an outlet. Also, make sure the breaker on the power strip isn’t tripped if it has one.
Blown Fuse: If the power cable is fine, there could be a blown internal fuse causing the issue. Open the back of your subwoofer and locate the fuse on the PC board. Inspect it to see if it’s blown, but be careful when working inside an electronic device.

Remember to exercise caution while handling electronic components. If you’re unsure about dealing with the fuse, it’s best to consult a professional technician for help.

Professional repair might be expensive compared to the subwoofer’s value.

Consider Replacement

If repair costs are high, buying a new subwoofer may be a more cost-effective and faster solution.

How To Reset Your Onn Subwoofer & Soundbar

If your Onn subwoofer stops working, don’t worry; you can easily fix it by resetting the device. A reset reboots the software inside your device which helps fix lots of bugs and minor issues, such as connectivity problems. It’s fast and easy to do and won’t damage the device.

A reset is essentially just turning off and unplugging your devices, waiting about 60 seconds, then plugging them back in and turning them on. Inside electronic devices is short-term memory called a cache that stores temporary files. A reset clears the device’s cache and reboots its internal software and programming.

A reset is automatic once you power down and then power up an electronic device. However, you may have to manually pair the devices after resetting them if they don’t connect automatically.

Switch off the subwoofer using the toggle switch on the back panel.
Disconnect the power and HDMI cables after turning off the wall socket.
Wait a few minutes, then reconnect the subwoofer’s power cable and switch it on.
Reset the soundbar and attempt to reconnect the subwoofer.
Before resetting the soundbar, ensure all cables connected to it and the subwoofer are removed and the power is off.
To reset the soundbar, press and hold the source button and the up and down volume buttons.

Why is My Onn Soundbar Blinking Red?

If your Onn Soundbar is blinking red, it’s likely due to insufficient power. Here are some things you can do to fix it:

Use the provided USB cable: If you’re connecting the soundbar to your TV via USB for power, use the specific USB cable that came with the soundbar. This cable might deliver enough power from your TV.
Connect to a power outlet: If your TV can’t provide enough power, use the adaptor that came with the soundbar to connect it directly to a power source.
Try a different USB port: If you’re using the first USB port on your TV, switch to another one. Different ports may provide varying power levels, so this might solve the issue.

Onn Soundbar Not Loud Enough

If your Onn Soundbar isn’t loud enough, there could be a few reasons for this.

Energy-Saving Mode

The soundbar might go off during use due to an energy-saving mode.
Adjust the setting in the menu to prevent it from affecting your soundbar’s performance and lifespan.

Improper Volume Calibration

An improperly calibrated volume can also cause low sound output.
Set the volume to maximum on the source device, then adjust it using the remote control.
This prevents the energy-saving setting from activating when no audio signal is detected.

Onn Soundbar Keeps Shutting Off

If your Onn Soundbar keeps shutting off, it might be due to certain settings that trigger a shutdown when no active audio signal is detected, such as energy-saving settings.

Energy-Saving Settings

Energy-saving settings are good for the environment and your wallet but can be frustrating if they cause frequent shutdowns.
Incorrectly calibrated volume might be a reason for the shutdown.
