How to Fix TCL Sound Not Working
If your TCL TV has no sound but has a picture, start by checking the volume, connections, and audio settings. Next, restart the TV and update the software.
If these steps don’t work, power cycle the TV by unplugging it from the power source and waiting a few minutes before plugging it back in.
1. Check the Volume and Mute Settings
The first and most obvious step is to check the volume and mute settings on your TCL TV. You may have accidentally muted the TV or turned the volume down too low.
Grab your TV remote and look for the volume buttons to check this. Press the “+” button to increase the volume or the “-” button to decrease it.
If the TV is muted, you should see a mute icon on the screen or hear a beeping sound when you press the volume buttons. Press the “Mute” button again to unmute the TV.
2. Power Cycle Your TV
Power cycling is a simple and effective troubleshooting step that can resolve many common issues with your TCL TV.
- Press the power button on the TV or the remote control to turn off the TV.
- Unplug the TV from the power source. This may involve unplugging the power cord from the wall outlet or removing the power cord from the back of the TV.
- Wait 2-3 minutes before plugging the TV back in. This allows time for the TV to discharge any residual power.
- Plug the TV back into the power source. Ensure the power cord is securely plugged in and the outlet functions correctly.
- Turn on the TV using the power button on the TV or the remote control.
When you turn on your Roku TCL TV again, the sound should function without delay or lag.
3. Restart Your TCL TV

- Press the Home button five times on your TCL TV remote
- Hit the Up button once.
- Press the Rewind button twice, then the Fast Forward button twice afterward.
It will take a few seconds for your TCL TV to reboot. It’s a good idea to test the TV’s sound after a restart to see whether it’s working.
If that doesn’t work, try resetting your TV from the menu options to see if it fixes the sound on your TCL TV.

Your Roku player will immediately begin verifying your Internet and wireless connections.
After the check, you should receive a popup that says, ‘Connection check was successful.‘
If the connectivity test fails, you should double-check the settings on your router and try again.
Additionally, if you’re using an Ethernet cable, ensure it’s correctly plugged in.
