How do I reset my LG television to factory settings?
Step 2: open All settings
Select the option Support and press the OK button. The enter button is the button centered between the arrow buttons.
Step 3: navigate to General
Select the General option. This option looks like a gear and a screwdriver.
Step 4: go to Reset to Initial Settings
Go down until you see the Reset to initial settings option. Select it.
Step 5: confirm the reset
The television will now ask you if you're sure you want to reset all of the settings. Select Confirm. Enter your password.
The television will repair itself and shut down when it's done. Turn the television back on to re-calibrate your settings.
