How to fix LG TV with no sound?
Several technical glitches can be the reason behind the no-sound issue on your LG TV. You can try to turn it off and, after 5 minutes, turn on the TV, which will give a simple reboot. If this is not enough to fix minor bugs, then go through the list provided below:
Power Cycle LG TV
You can try to Power Cycle the LG TV, which is also known as Soft Reset for your TV.
To proceed – Unplug your TV from the power socket and leave it for 1 to 2 minutes. Now, locate the Power button on the TV and keep pressing it for 30 seconds.
You need to plug the TV back into the power socket, and when the TV starts, check whether power cycling has helped to fix the error. Remember, this won’t change the settings or delete any data, and it is a smart alternative for Hard Reset.
Change the LG TV Sound Settings
If there is a misconfiguration in the TV sound setting, then there won’t be any sound coming from your LG TV. So, to turn off Smart Sound mode, you need to go to the TV settings. Click on the Smart button on the remote control and then choose the Settings icon. Next, click on the Sound tab and look for Smart Sound Mode Option. Tap on it to turn it off in case it is enabled.
Switch from Auto to PCM for Digital Sound Out

To proceed – Click on Settings > All Settings > General. Now, scroll down to locate Reset To Initial Settings, click on it, and you need to confirm your action by pressing on Reset. Now, you will get the option to set up your TV from the beginning.
