My Samsung TV, which I've had for probably 5 or 6 years, suddenly has a weird problem: twice in the past month, the V-chip has turned itself on to block TV-14 and TV-Y7-rated shows. I am the only one who lives here, no kids, have never even *looked* at the V-chip menu before, but luckily I finally figured out the PIN was 0000 and could reset the V-chip to allow all shows. But why would this suddenly happen? And HOW would it just change settings out of the blue? I'm just puzzled, and wondered if anyone has any answers or theories. Thanks.
