How To Fix A Subwoofer With No Sound

Here are some basic instructions for how to fix a subwoofer that doesn’t produce sound for your home theater.

Check Speaker Wires And Connections

Start with the subwoofer and check for all connections to receivers, amplifiers, or speakers. Make sure cables are securely connected and plugged into the right spots.

The inputs from the subwoofer plug into the outputs of receivers and amplifiers. Inspect the entire length and connections of the subwoofer that connects to the speaker outputs of the car amp or receiver for any defects. Replace any damaged or worn wires immediately before you attempt to use the equipment again. To ensure that the wires work properly, perform a quick test.

Examine Every Component Of Your Subwoofer

Before you begin, it is worth taking the time to inspect every component of your subwoofer.

  • You should ensure that the subwoofer is connected to the TV’s MIX/SUB output (subwoofer output).
  • Make sure that the subwoofer’s power cable is connected to an AC outlet.
  • Activate your subwoofer.
  • You should make sure that the subwoofer does not get muted.

Check The Volume Of Home Theater

Check the volume of Home Theater

If you have problems with your home theater system, a simple check of the settings in your receiver can help. It is easy to forget to set your home theater receiver settings.

Depending on which brand or model your receiver is made from, the options and features that you choose may be included in the receiver.

Many A/V Receivers have volume knobs that can be moved in any direction. It is difficult to determine your volume level simply by looking at the knob. You need to ensure that the volume level is sufficient to allow you to hear all of your speakers.

Some A/V receivers include a Muting/Mute button. These buttons do not have an indicator bulb to indicate that they are being used. Make sure your receiver isn’t turned off or on when you press this button.

If your A/V receiver has a knob for a speech selection, you might not be able to hear or deform audio. This button may need to be set differently depending on where the speakers are located in the receiver’s back.

If you have headphones attached to your home theater system, no sound will be heard. Double-check that your headphones are not connected.

Make Sure Your Home Theater Has The Right Input

Your A/V receiver and tv components may need to adjust their “input” and “source” settings to ensure sound and picture quality. It all depends on how many components are in your home theater and what wires you use. Each case is unique. These instructions explain how to check and adapt the input parameters for your components in order to make sure they work properly.

If you don’t have sound or video, it could be an issue with your inputs. Your speakers might have the wrong information.

  • To modify or detect sources on your TV:
  • Use the Source or Input buttons to locate your remote TV.
  • Tap the remote and hit the Source or Input buttons to cycle the screen.

If you are satisfied with the input choice and want to check it out, simply stop pressing the input button. The input option will be displayed on the TV within a few seconds.

Most often, your sound system is connected to an HDMI connection. This allows you to connect one cable to transmit sound and video to the television.

Check your A/V Receiver To Verify That You Have Not Changed Sources.

Some A/V receivers have knobs that allow them to adjust the source or input they use.

Some buttons are actually buttons, while others have a knob that can be used to select inputs.

Alternatively, A/V receivers can be connected to their remote controls with buttons for source or input.

Simply click or spin the button to select the input or source button you desire.

Check Speakers Using Test Tones

If you are having trouble hearing the speakers connected to your receiver, it is possible to still test the receiver to see if the receiver can produce the sound.

Many receptors include a ” speaker setup” option. This allows for increased sound intensity and test tones to be sent either to one speaker or to the entire system at once. You can decide whether or not the receiver can broadcast audio to its connected speaker.

Check out Your Home Theater Cabling

If you are unable to hear the test tones coming from your speakers, the next step is double check that the speaker wiring is properly connected to the receiver.

There are many ways to connect speaker cables and receivers. Make sure that the speaker cables’ bare wires are in good contact with binding posts, poles, or ports.

Spring-loaded clips are used to attach A/V receivers. Make sure that the wire is properly inserted and in good contact with each port. If wires are pulled on, this type of connection can break.

Make sure that the binding posts or poles on your A/V receiver are secured so that the speaker wires do not slip out of the receiver.

Some speaker wiring doesn’t use color codes to indicate positive or negative. Instead, it uses text labels and a single line of code to identify positive and negative. Double-check the connection of the positive and the negative ends at each speaker and receiver.

Make sure all connections to the receiver are secure and complete, except for the speakers.

Verify Your Sound System And Menu Settings.

Check that all wires and cables are in good condition. If not, you should revisit the menu settings of your amplifier or receiver. You never know who might have changed them. Verify that the subwoofer has been connected to the correct audio input settings. Also, ensure that the output of the subwoofer has not been reduced.

If an input device has speaker size settings, select the smallest. Sometimes setting the speaker size too high can cause the subwoofer to not receive any signal. Subwoofers can be operated with large speaker settings on some receivers. Refer to your product manual for more details.

Why do you need a subwoofer in a home theater?

Subwoofers are necessary because most speakers in an audio system or home theater system can’t reproduce all frequencies. You will miss some of the sounds if you don’t own a subwoofer. Low frequencies are also a great way to create rich, rich soundscapes in music and movies.

If your Home Theater Sound System is Still Not Working

After checking the altering settings and all other options, if you still don’t have sound in your home theater system, contact the manufacturer. If possible, connect a second subwoofer directly to the transmitter device to verify that the problem is not caused by the sender. If the second subwoofer works, it’s very likely that the first one was defective.
