LG, like most television manufacturers, includes a parental lock on its televisions that, when enabled, prevents certain television programming from showing on the TV. Television programs rated at specific levels of inappropriate content are blocked from the television so that children are not exposed to the offensive material. You can remove the parental lock from your LG TV so that you can watch the blocked channels.
Press the "Home" button on your remote control to access your LG TVs "Home" menu.
