Is not owning a TV a sign of instability ?

Recently I was talking to a lady who cleans homes/apts as a side business,she cleans the apt. of a guy we both know but she told me,she feels uncomfortable going to his place as he’s a weirdo,she commented “He does not even have a TV,for God’s sake” My first reaction was; yes,she’s right !!
Then I asked myself, why is not owning a TV a sign of mental instability ?
