TCL Subwoofer Not Working

Black subwoofer on the floor

TCL subwoofers are a great way to boost the audio for movies and music. Your home is transformed into a private theater and concert hall. What can you do when the TCL subwoofer is not working?

If the TCL subwoofer is not working, make sure the HDMI connections are securely inserted into the correct port. Inspect the cable for any signs of visible damage such as kinks or fraying. Unplug any external devices that are not in use. Do a hard reset.

It can be very frustrating when the TCL subwoofer does not work. While TCL subwoofers are affordable and reliable, it can be stressful to troubleshoot problems because the subwoofer has minimal controls.

Here are some common reasons why your TCL subwoofer is not working.

Connection and Wires

Any connected cables and wires that are loose or inserted into the wrong port will cause the subwoofer not to work. Inspect all of the cables and wires for any visible signs of damage.

Power Source

The subwoofer needs an adequate and steady supply of electricity in order to work correctly. If the subwoofer is connected to a wall outlet, unplug the subwoofer and perform “the lamp test”. Plug a small lamp or other appliance into the outlet to see if it is supplying enough electricity.

Make sure the subwoofer is securely plugged into the wall outlet. If any prong of the subwoofer power cable is loose or not inserted completely, the subwoofer will not work.

Another cause for a subwoofer to not work is if the prong on the power cable is bent. This can happen if the cord is yanked from the wall outlet. Carefully bend the bent prong back into position and plug it back in.

Menu Settings

Check the subwoofer audio settings to make sure it is associated with the proper audio input selections. If the subwoofer’s audio settings have been adjusted too low, the subwoofer will not work.

Adjusting the subwoofer size to a smaller size. Setting the speaker size too high will prevent the subwoofer from receiving a signal.

TCL Subwoofer Making Noise

Is your subwoofer humming or making other noises? Here are some reasons why this is happening.

If your TCL subwoofer is making noise, reverse the polarity of the subwoofer’s connection by reversing the power plug’s orientation. If one prong is wider than the other, use an AC ground adapter to reverse the polarity. Reverse the plugs for other components on the same power strip.

Oftentimes the noise coming from the subwoofer is caused by an external source, not the subwoofer itself. This is common when the subwoofer is connected near other audio cables.

Signal Bleed

The proximity of the cables to each other creates a signal bleed. The signal from one cable bleeds over to the next cable, creating noise. The best way to resolve this problem is by spacing the cables apart. If you are not able to move the cables, switch out the cables for an audio cable with more effective shielding.

TCL Subwoofer Not Pairing

The subwoofer should pair automatically to the soundbar. Why is the TCL subwoofer not pairing?

If the TCL subwoofer is not pairing, unplug the subwoofer and soundbar for 3 minutes. Make sure the subwoofer and soundbar are connected to a working outlet. When manually pairing the subwoofer, press the Pair button on the back of the subwoofer.

The subwoofer should automatically pair to the soundbar when both are powered on. If the subwoofer does not automatically pair, you can pair the subwoofer manually.

Step 1: Connect the subwoofer to a working power source.

Step 2: Turn the soundbar on.

Step 3: Using either the remote or the soundbar, press and hold the Input Selection button.

Step 4: Continue holding the button until the 4 LED lights on the soundbar start flashing.

Step 5: Press and hold the Pair button on the back of the subwoofer.

Step 6: Continue holding the Pair button until the amber LED light starts flashing.

Step 7: After a few seconds, the light should go solid and the lights on the sound bar will stop flashing.

Step 8: The subwoofer and soundbar are now paired.

If the amber LED light continues flashing, the subwoofer and soundbar were not successfully paired. Unplug both the subwoofer and the soundbar. Let them remain unplugged for at least 3 minutes.

After 3 minutes, plug them back in and repeat the steps outlined above. Once the subwoofer has successfully paired with the soundbar, power cycle the soundbar a few times to make sure the subwoofer remains paired.

The amber light on the subwoofer is how you will know if the subwoofer has remained paired. When the soundbar is powered off, the amber light will go from solid to a slow blink. When the soundbar is powered back on, the amber light should go solid.

TCL Subwoofer Too Loud

You find the bass level of the subwoofer to be too much. What can you do if the TCL subwoofer is too loud?

If the TCL subwoofer is too loud, adjust the sound settings found in your TV’s settings. The ‘Movie’ setting will have more bass. ‘TV’ will have more vocals. ‘Music’ is between the two other settings. The subwoofer itself does not have a way to adjust the sound output.

Unfortunately, there is no way to adjust the subwoofer level. You can try moving the subwoofer to a different location to reduce the volume, but ultimately the volume of the subwoofer is not adjustable.

TCL Subwoofer No Sound

You have everything connected and you are ready to enjoy the fruits of your labor. You turn on the subwoofer and nothing happens. Why does the TCL subwoofer have no sound?

If your TCL subwoofer has no sound, the issue may be with the HDMI cable. Make sure the cable is securely connected to the correct port. Inspect the cable for any visible signs of damage such as fraying, bent pins, or severe kinks in the cable.

The HDMI cable also needs to be capable of handling the audio output from the subwoofer. If the cable you are using is several years old, it may be time to upgrade.

ARC Settings

Connecting the subwoofer to the TV requires the settings within the TV to be adjusted. If the ARC settings have not been adjusted, no sound will be routed to the subwoofer. Here is how you can check this setting.

Step 1: Go to your TV Settings.

Step 2: Select System.

Step 3: Select Control other devices (CEC).

Step 4: Select Search for CEC devices.

Step 5: Select the ARC (HDMI 1) box.

These steps may vary depending on the model of TV you have. Your TV may require you to go to Settings and then to Audio. Select Audio Output to see if the ARC HDMI 1 is selected as your audio source.

TCL Subwoofer Keeps Disconnecting

You’re enjoying your favorite movie or music and the subwoofer disconnects. Why does the TCL subwoofer keep disconnecting?

If the TCL subwoofer keeps disconnecting, power cycle the subwoofer. Unplug the subwoofer and let it rest without power for at least 3 minutes. Move the subwoofer closer to the soundbar. Plug the subwoofer back in.

The signal from the router will also cause interference with the subwoofer. Move the subwoofer and router far away from each other.

TCL Subwoofer Not Loud Enough

Are you having a hard time hearing the audio coming from your TCL subwoofer? Here is how you can troubleshoot the issue.

If the TCL subwoofer is not loud enough, make sure the subwoofer and soundbar are connected to the correct HDMI ARC port on the TV. Go to the TV Settings and make sure the CEC controls are active. Set the TV speakers to ‘S/PDIF and ARC’ ‘Auto Detect’.

TCL subwoofers do not have a manual way to adjust the volume or audio settings. If adjusting the TV audio settings does not resolve the issue, contact TCL support for more information.

TCL Subwoofer Not Turning On

You would like to hear the great sound the subwoofer produces but the subwoofer is not working. Why is the TCL subwoofer not turning on?

If the TCL subwoofer is not turning on, the subwoofer may be stuck in standby mode. Turn off the subwoofer and unplug it. Let the subwoofer rest without power for 10 seconds and then plug it back in. Make sure the cables are connected to the correct ports.

A recent power surge or incorrectly connected cable will keep the subwoofer in standby mode. Removing power from the subwoofer and letting it drain off excess will electricity will oftentimes resolve the issue.

If the TCL subwoofer is paired but no sound, disconnect the subwoofer and pair it again. Press and hold the Input Select button until the LED light starts flashing. Press the Pair button on the back of the subwoofer until the LED light flashes.

The TCL subwoofer will indicate it is paired but if there is any glitch in the pairing process, the subwoofer will not work. Power cycling the subwoofer by unplugging it for 10 seconds will refresh everything. For more stubborn cases, disconnect the subwoofer and then pair it again.
