One of the standout features of LG TVs is its user-friendly WebOS platform. With intuitive navigation and the Magic Remote that mimics a computer mouse, interacting with your LG TV is virtually effortless, which is great news for smart TV beginners. LG’s multitasking capabilities also let you switch between apps, inputs, and live TV swiftly, all so you don’t miss a moment of your favorite show.

However, a lesser-known feature of LG TVs is the hidden menu, designed primarily for technicians but accessible to the public. This menu is useful for making a handful of adjustments, like fine-tuning HDMI input settings, modifying network configurations, and performing factory resets for persistent issues. Think of it as a valuable tool in an LG owner’s toolkit.

You’ll need a few things first

In order to access your LG TV’s hidden menu, you’ll need to know your LG TV model number, its year of manufacture, and have the original remote control that came with the TV on hand (universal remotes won’t work). The process may vary slightly based on your TV’s model and manufacturing year.

Once you have everything you need, here’s what to do:

Turn on your TV and set to the home screen or a live cable channel — not in input, standby, or other modes.
Press the ‘Menu‘ button on your LG TV’s original remote to bring up the on-screen menu. You will be prompted to enter a code by pressing the “Settings” button, scrolling to “All Settings,” and pressing the ‘0‘ button five times.
Depending on your LG TV model, you may need to press different button sequences, such as ‘Mute‘ followed by a unique numeric code.
Once you enter the correct sequence, the hidden menu will appear on your TV screen. This menu differs significantly from the usual settings menu and focuses more on diagnostic tools.

Make sure your TV is on and set to the home screen or a live channel before accessing the hidden menu.
