The Panasonic Viera line of televisions has a parental lock that you can set to prevent your children from watching programming with mature content. In addition, you can set the Viera parental lock to block channels that are used for gaming and to prevent access to the Internet through the television. Disable the parental lock when you want full access to your TV again without the need to input the lock code when you tune in to a blocked channel. Writer Bio
