A:Answer Hi Matt. The LG 43 Inch Class 4K HDR Smart LED TV (42.5'' Diag), Model # 43UM6910PUA has a 'TV Program Locks' feature that locks the shows that you do not want your children to watch. In addition, it locks the TV shows of your choice based on ratings by using the parental control function (V-Chip). It has a 'Movie Lock' that blocks films that are broadcast and contain inappropriate content, based on the Motion Picture Association of America (MPAA) rating. The 'Channels Locks' blocks the channels that contain inappropriate content for children. The channels can be selected but the screen is blank and the audio is muted. To watch a locked channel, you will need to enter the password. The 'Application Locks' allows you to lock or unlock apps and the 'Input Locks' allows you to lock or unlock the inputs on the TV. You can select which inputs to lock...^IFV
