Step by step
Do a hard restart
Turn the TV off and unplug it for 60 seconds. With the cable still unplugged, hold the power button on the TV for about 30 seconds, then plug it in and turn it on.
Update the software
In the settings (Support or Update), check for an update and check the internet connection.
Check the app
If one app stutters, clear its data and cache, or uninstall it and install it again.
Disconnect HDMI devices
Unplug the HDMI cable from the set-top box, console or soundbar. Check whether one of the devices is causing the freezes.
