What is the LG TV Service Menu?

The LG TV Secret Menu, also known as the Secret Menu or Engineer Mode, is a concealed interface designed primarily for technicians and developers. It contains advanced settings not available in the regular user interface. While it’s not intended for normal users, accessing it can provide helpful insights and fine-tuning options for those who understand its functions.

Warning: Accessing the Secret Menu requires caution. Avoid making changes you don’t understand, as it may disrupt your TV’s functionality.

How to Unlock the Secret Menu on LG TV

Accessing the Secret Menu varies depending on the model of your LG TV. Follow the methods below to find the one that works for your device:
