But, before you call in the experts, try a few different troubleshooting methods to see if you can solve the problem on your own. For many owners, the problem is usually obvious and simple; all it takes is a little digging to find out. If your TCL Sound isn’t working or has suddenly stopped working, check your remote first.

There is a mute button on the side of TVs that have a Roku remote controller, but it is quite small. Even with its small size, it is very easy to push, which is sometimes one of the main reasons why owners complain about their sound not working.

If the mute button isn’t the issue, try switching to a different station or application to see if the channel you’re on is causing the issue. If this is not the case, ensure that the HDMI connection on the back of your TV is secure, as well as any other device connected to your TV. Any loose cords can easily disrupt your TCL TV’s audio.


The lack of sound on your TCL TV is inconvenient, but when it comes to frustrating situations that almost make you want to crawl out of your skin, there are few things worse than the sound not matching the picture properly.

When the sound does not match the picture, most TCL TV owners notice that it is lagged behind the picture, causing the mouths and scenes to move faster than the audio output.

If the sound on your TCL TV does not match the picture, it could be because the ‘Volume Mode’ on your TV is turned on. To disable “Volume Mode,” simply press the “*” symbol on your remote control and navigate to the “Volume Mode” setting.

Once there, if you notice that this setting is enabled, simply select the option to disable it, and your audio sync problem should be resolved. If your TV’s volume mode is already turned off, you know this isn’t the issue.

If you’re using a soundbar, turn it off and leave it off for at least 60 seconds before turning it back on. If you aren’t using a soundbar, try performing a power cycle by unplugging your TV from the power source, letting it sit unplugged for 60 seconds, and then plugging it back in.


When you turn on your TCL TV and there is no sound, or it keeps losing sound, or the sound simply does not work, there are a few different solutions you can try to restore the sound. Make certain that the volume level is not set to (0) or that the television is not muted.

To test this, either use the mute button on your remote or increase the volume on the right side of the remote. If your TCL TV doesn’t have sound, keeps losing sound, or the sound isn’t working and the volume isn’t the problem, check the audio settings on your TV.

To do so, press ‘Home’ on your remote control > ‘Settings’ > ‘Audio’ > scroll and select ‘Audio Mode’ > scroll and highlight ‘Audio (Stereo)’ > then press OK to confirm your settings.

When you’re in the middle of an action-packed movie, nothing beats getting the full theater experience by turning up the volume to the point where you can almost feel it in your bones.

Similarly, on a lazy Saturday afternoon, there’s no need for the relaxing music you’re listening to to be turned up to 80, as a lower volume is more appropriate. What should you do if your TCL TV‘s sound won’t turn up or down?

If the sound on your TCL TV won’t turn up or down, check to see if the problem is with your remote or the control board. To accomplish this, turn off your TV and then, as you turn it back on, press the volume (-) button down.

If you don’t notice an automatic increase in volume when you turn on the TV, your remote button is stuck. If you do notice an automatic increase, there is a problem with your control panel.


The problem of your TV’s volume randomly going up or down on its own is perhaps even worse than the volume being stuck either too loud or too quiet.

If you’re sitting on the couch without touching the remote and the volume suddenly starts to rise, it can not only startle you, but it can also reach levels so high that you can’t even be in the same room. What should you do if this problem with your TCL TV persists?

If the volume on your TCL TV keeps going up and down, make sure it’s not your remote by replacing the batteries and seeing if that stops the increase or decrease.

If this persists, ensure that the Roku phone application is not being accessed while you are watching TV, as volume can be controlled from here. To isolate the problem, you can also install a soundbar and turn off the sound in your TV speakers.


If your TV’s volume is working but suddenly cuts out, you may miss important scenes, beautiful melodies, and more, leaving you wondering what is causing such a sporadic issue. If the audio on your TCL TV keeps cutting out, read on for a few solutions.

One of the most common causes of TCL TV audio cutting out is a loose cord on the back of your TV. Make sure that all of the cords are securely inserted into the TV so that your audio does not suffer from interference.

If this is not the case, you may need to reset your Roku. To do so, use your remote to navigate to ‘System’ > ‘Power’ > ‘System Restart’ > ‘Restart’ > ‘OK.’
