I have what I could best describe as 'scan lines' that slowly make their way up the screen as I'm watching TV or DVD. I called Infocus (I have an X1) and the tech there told me I need an RF isolator because of something called 'ground loop'. Has anyone had this experience (and how did you solve it)?
