Sony Subwoofer Not Working (How To Fix/Reset)

Your Sony subwoofer could fail to work for many reasons, including faulty connections or an outlet that has no power. Rectifying the problem doesn’t usually require taking the unit in for servicing, but it can as a last resort.

Always check the outlet’s power first. Many electrical outlets turn on by a switch on the wall. If this doesn’t rectify the problem, try the nine solutions in this article.

Sony provides some simple fixes to reset the electronic components in the stereo system to their factory settings. In some cases, you need to move the equipment physically. This may mean rearranging your stereo components or your furniture. Other common solutions include using new power cords and stereo component cords.

Sony Subwoofer Not Powering On

The subwoofer shows no life. The power indicator light remains dark. Your music doesn’t include any bass in playback.<

Typically, when a Sony subwoofer won’t power on, it needs to be plugged into an electrical outlet. Although the subwoofer works wirelessly, you still have to plug it into the wall. Check the back of the subwoofer and the outlet to make sure the cord connects to the other device.

Check your cord, too. Any frays or tears in it can preclude it from working. Check the plug that goes into the outlet for all three prongs. You may need a new electrical cord. Press the power button on the subwoofer and look for an indicator light to show that the power came on. Try a new power cord.

Sony Subwoofer Not Connecting To Soundbar

You’ve tried multiple times to get the subwoofer and soundbar to connect. Despite following the instructions to the letter, the soundbar won’t recognize that you added the subwoofer to the stereo.

Resetting the subwoofer provides the quickest fix for a subwoofer and soundbar that won’t connect. Each model of subwoofer uses a different method of resetting, so check your user manual.

Essentially, you’ll ensure both devices have power. Press the power buttons on each. To power down the soundbar, you press and hold the input selector button, volume button, and power button simultaneously. This turns off the soundbar.

Press the power buttons on the soundbar and the subwoofer to turn them both on. It also resets both to factory settings. If it doesn’t work, repeat the power button process, then unplug the power cord from the outlet for five to 10 seconds. Plug it back into the outlet, then press the power buttons on both devices to turn them back on.

Sony Subwoofer Not Loud

You sit down to watch a movie with surround sound and notice that the subwoofer volume seems very low. You check the volume setting though and it appears normal.

Since a subwoofer only handles the bass in music or broadcast, you won’t hear much from it when watching a TV broadcast. Test the sound volume using a piece of music with lots of bass, then adjust the volume settings using it.

If the subwoofer isn’t playing sound or plays too low of sound when you test it with a piece of music with lots of bass like something by Snoop Dogg or Nas, then you need to change the settings on the subwoofer volume. If you’re watching a TV broadcast of Martha Stewart, you won’t notice the bass and the subwoofer will seem to not work.

You can turn up the volume on the subwoofer using its volume knobs or its remote control. Start with a setting of 0dB. Also, double-check the connection between the subwoofer output jack on the receiver and the line level input jack(s) on the subwoofer.

Sony Subwoofer Not Pairing

Similar to when the subwoofer and soundbar won’t connect, sometimes they won’t pair. This means the stereo system doesn’t recognize the device, so the subwoofer can’t process the bass sounds.

A full reset of the stereophonic system typically rectifies this problem.

Unplug both the soundbar and the subwoofer for two minutes. Plug each back into the active wall outlet. Turn on the subwoofer. Press the pairing button. Look for the blinking LED light. Turn on the soundbar with the remote if your system uses one. Manually press the dim display button for five seconds, then press the bass setting buttons (plus and minus settings).

Sony Subwoofer Keeps Cutting Out

During playback of your favorite music, the bass sounds sometimes drop out completely. You hear only treble, then the bass resumes.

Your subwoofer could incur interference from a device generating electromagnetic waves or could need a wired connection. Try moving the speakers away from your microwave or wireless LAN.

Also, remove any obstacle between the subwoofer, soundbar, and/or rear speaker. Move the soundbar and subwoofer closer to one another.

Also, try switching from a wireless LAN to a wired LAN. Try connecting the subwoofer to a LAN with no other devices on it.

Check that the subwoofer’s RF Channel reads “on.” If the above options didn’t work, reset the RF Channel. Press the home button on the sound bar remote control. Go to Setup, then Advanced Settings. Select Speaker settings, then wireless speaker settings. Turn off the RF Channel. Wait a moment. Turn the RF Channel on again.

Return to the wireless speaker settings, choosing wireless playback quality. Set it to Priority on stable connection.

Sony Subwoofer Keeps Turning Off

You turn on the radio only to find you have no bass because the subwoofer turned itself off. You can manually turn it back on so it doesn’t seem to indicate a short in the system.

Some Sony subwoofers include an energy-saving feature to help consumers reduce their energy costs. When the consumer has this feature enabled, the subwoofer turns off automatically. You may have set your device to power save mode, so switching out of this mode fixes the problem.

Check your user manual to learn if your subwoofer features an energy-saving mode that powers off the subwoofer if the amplifier turns off. To fix this, turn the Power Save switch to the  ‘off” setting. Not all subwoofers have this setting.

Sony Subwoofer Beeping

The subwoofer starts emitting an incessant beep. It’s quite audible and driving you up the wall. Is it sending out Morse code?

A beep indicates the subwoofer and bar speaker need to move closer to one another to form a secure link or the unit requires servicing. Move the subwoofer nearer to the Bar Speaker. When the on/standby indicator lights turn green, they’re close enough.

If creating a Secure Link does not resolve the problem or if the Standby indicator flashes a green light quickly the subwoofer needs servicing. Take it or ship it to the nearest authorized service center in your area. Typically, you’ll need to contact Sony for a return for servicing number that you must include on the outside of the packaging and the inside of the package.

Sony Subwoofer Light Flashing

You come home to find that the power light on your subwoofer flashes incessantly. This quite bright light won’t stop and rather than cover it with tape, you want to know what it means.

If the light flashes green, it means the subwoofer is on. If it flashes orange or red, the subwoofer sits too far away from the main stereo components. Move the subwoofer closer to the main stereo unit. Place it in an unobstructed line with the system.

The wireless subwoofer needs unobstructed communication, so move it to an area of the room that allows it direct contact with the stereo’s feed. Make sure there aren’t any furnishings, walls, or metal objects between it and the stereo.

How To Reset Sony Subwoofer

Sometimes, you just want to scrap the whole setup and start over again. You can reset your Sony subwoofer pretty easily to solve most issues with the stereo component.

Just as when the subwoofer refuses to connect with the soundbar, you can reset the subwoofer to return it to factory settings. Each model of subwoofer uses a different method of resetting, so check your user manual.

Essentially, you’ll ensure both devices have power. Press the power buttons on each. To power down the soundbar, you press and hold the input selector button, volume button, and power button simultaneously. This turns off the soundbar.

Press the power buttons on the soundbar and the subwoofer to turn them both on. It also resets both to factory settings. If it doesn’t work, repeat the power button process, then unplug the power cord from the outlet for five to 10 seconds. Plug it back into the outlet, then press the power buttons on both devices to turn them back on.
