Use your TCL TV remote to control the TV’s volume with these quick steps:

• Press Volume + or Volume – to increase or decrease the volume.

• To mute, press and hold Volume – for about 5 seconds.

Tips and troubleshooting

• If the volume buttons don’t work:

  • Make sure the remote has a clear line of sight to the TV (nothing blocking the front of the TV).

  • Replace the remote batteries and try again.

  • Restart the TV (unplug for 30 seconds, then plug it back in).

• If you’re using a soundbar or external audio system:

  • Your TV remote may not control the soundbar volume unless the soundbar supports HDMI-CEC/ARC (or is paired via Bluetooth, depending on model).

  • Try adjusting volume with the soundbar’s remote and confirm the soundbar input is set correctly.

• If you see an on-screen volume icon but hear no sound:

  • Check that the TV isn’t muted and that the correct Audio Output is selected in the TV’s sound settings.
