Mebbe someone playing tricks with the remote? smile.gif
could be or someone playing tricks with another remote that turns it off also
Sometimes with some sets if you walk away from the TV and it is not getting a signal it *may turn off ,if it does it again
Make sure sleep timer is not accidentally activated if not ,
Unplug the TV for a minute or so then ofc plug it in and turn it back on
Next thing to to would be a factory re set note : that will restore all...
