Solution 1: Power cycle your LG Smart TV The first thing you will need to do in this case is to power cycle your LG TV. Power cycling is the process of turning off the TV then turning it on again.

Wait for about 10 seconds, then press the power button again to turn the TV on. LG should go through a longer startup process than usual as it installs the update. Now you should be good to go.

Force reboot TV. Press and hold the power button on the LG TV for at least 10 seconds. When the LG TV turns off unplug its power cord from the power source.
