I know how to apply a PIN to individual apps. I think I know how to apply parental controls for tuner channels but I don't use that so don't need it. My TV is connected to my Home Theatre receiver which has all sorts of other things connected to it. I need to control my children's access to screen time but I don't know how to lock that source or the entire TV (my previous TV had that option, required a PIN after power up). Is this even possible? Thanks!
