Including parental controls, display adjustments and sound settings, your Insignia TV offers a wide variety of ways to customize the viewing experience -- but you might end up making it worse instead of better. For those situations, the Reset option can be a quick fix, as it restores the TV's from-the-factory default settings. Selecting this option erases all customizations, including parental controls, so you'll need to go through the first-time setup all over again after resetting the TV.
Press the "Menu" button on the Insignia remote control.
