Why Can't I Remove Child Lock?

Users commonly experience issues because:

  • A PIN code is required.
  • The parental control settings are enabled.

  • The TV software requires restarting before changes take effect.

Quick Steps to Remove Child Lock

Factory Reset LG Smart TV

Resetting your TV can solve many software-related problems. Before resetting, it's important to understand the different reset options.

Restart

A normal restart powers the TV off and back on. This clears temporary memory and fixes minor glitches without any changes in settings.

Soft Reset

A soft reset refreshes the TV's operating system while preserving your apps, accounts, and personalized settings.

Factory Reset

A factory reset restores the TV to its original factory settings. This option is useful when there is a need to troubleshoot constant software issues or prepare the TV for a new owner.

  • Saved Wi-Fi networks
  • Installed apps
  • User accounts
  • Personalized picture and sound settings

  1. Open Settings.
  2. Navigate to General.
  3. Select Reset to Initial Settings.
