Nothing beats the immersive experience of watching your favorite shows on a big-screen TCL TV. The sounds of explosions, car chases, and emotional dialogue are integral to the experience. So, it can be frustrating when your TCL TV has no sound.
Your TCL TV may not have sound if it is muted, the volume level is set to zero, there is outdated firmware, or there are improper audio settings. Easy fixes include updating your TV’s firmware, checking and raising the volume, and checking and updating audio settings.
In the rest of this article, I’ll discuss the main reasons a TCL TV may not have sound. I’ll also take you through easy fixes to get sound back on your TV. Let’s get started!
Why Your TCL TV Has No Sound
You just grabbed a pack of popcorn and a remote, sat on your comfy couch, and turned on your TCL TV for a movie night. But as the opening credits start to roll, you realize there’s no sound from your TV. Before hitting that panic button, let’s figure out why this is happening.
The TV Is on Mute
A muted TV is the most common reason for no sound.
TCL TVs have a mute button on the remote control. The button has a red circle with a line through it.
Your TV is muted if the light next to the mute button is on.
The Volume Is Zero
It’s possible to lower your TCL TV’s volume to zero unintentionally. This can happen in scenarios such as:
- You accidentally pressed the volume down button on the TV remote while trying to turn up the volume.
- The TV was on, and someone playing with the remote control lowered the volume.
- Children or pets might have fiddled with the TV controls and turned down the volume.
An Outdated Firmware
Firmware is the software that helps your TV run smoothly. It’s stored in your TV’s internal memory.
Like any software, the firmware must be updated regularly to ensure optimal performance.
Although most smart TVs are programmed to install updates automatically, the feature only works when enabled. Therefore, your TV will not install firmware updates automatically if the automatic update feature is disabled.
Improper Audio Settings
The audio output settings on your TCL TV might be set to a format your TV doesn’t support. When this happens, you’ll hear a distorted or no sound from your TV.
Some common audio formats that can cause this problem are Dolby Digital Plus and DTS. You’ll need to change the audio output settings if your TCL TV doesn’t support these audio formats.
Poor Network Speed
You might be wondering what the internet has to do with your TV’s audio.
The internet plays a critical role in the production and quality of your smart TV’s sound.
If you’re using WiFi to stream, the internet processes and transmits the audio signal from the content provider to your TV. Thus, if you have a slow or poor internet connection, the sound might be delayed, interrupted, or not transmitted at all.
Fixes for a TCL TV With No Sound
The feeling of not hearing what’s happening on your TV can be frustrating. But don’t worry; in most cases, the problem is not severe and can be fixed quickly.
Let’s go through some easy fixes for a TCL TV with no sound.
1. Check if the Mute Button Is On
The first solution is to check your TV’s mute button and unmute it if it’s on mute.
As I mentioned earlier, the mute button on the TCL TV’s remote has a red circle with a line through it.
A light next to the mute button indicates your TV is mute.
Here’s how to unmute your TV:

- Find the mute button on your remote control.
- Press the mute button once while pointing the remote toward the TV.
- The light next to the mute button should turn off, indicating that your TV is no longer muted.
2. Raise the Volume
The second solution is to check your TV’s volume and raise it if it’s too low. Here’s how:
- Press the volume up button on your remote.
- Move closer to the TV. This ensures you can hear the TV better if its volume is low.
- Raise the volume to at least 50%.
If this doesn’t restore the TV’s volume, proceed with the following fix.
3. Power Cycle the TV
TVs encounter problems like losing sound when too many operations are running simultaneously. When this happens, a power cycle is necessary to restore the TV’s normal functioning.
Here’s the procedure to power cycle your TCL TV:
- Power off the TV.
- Unplug the TV from the wall outlet.
- Leave the TV unplugged for 60 seconds.
- Replug it into the wall outlet.
- Power it on
This should fix the problem if the TV needs to be power cycled. If not, try the next fix.

4. Check and Update the TV’s Audio Settings
TCL TVs have the option to turn off speakers. If this option is off, it’s the reason the TV doesn’t have sound.
Here is how to check your TV’s audio settings:
- Press the “Home” button on the remote.
- Navigate down to “Settings.”
- Select “Audio.”
- Select “Speakers.”
- Navigate to the right side of the screen and select “TV Speakers.”
Stay there and proceed with the following procedure to update the audio settings:
- Press the “Home” button again.
- Navigate to “Settings,” then select “Audio.”
- Choose “Audio Mode.”
- Press the right arrow on the remote.
- Highlight “Auto Stereo.”
5. Update the TV
If the issue persists, the next fix is updating the TV. Here’s how:
- Press the “Home” button on the remote.
- Navigate to “Settings.”
- Scroll to the right and select “System.”
- Click “System Update.”
- Select “Check Now.”
- Click “Update” if an update is available.
- Wait for the update process to end.
Restart the TV and check if the issue is solved.
Final Thoughts
A TCL TV with no sound may result from a simple issue like the volume being extremely low or a complex one like outdated firmware. Identifying where the problem arises is the first step to solving it. Once you know what causes the TV to lack sound, you can devise an appropriate fix from the ones covered in this article to restore normalcy.
