Every LG television hides a service menu — a secret engineering panel with factory-level options missing from the normal settings. With the right LG TV service menu codes, you can run a true factory reset, release a locked panel, switch on hotel mode, or recover a forgotten parental PIN.
In this guide you will learn three ways to open the LG service menu, the full password list, and the safe, useful options inside — plus the precautions that protect your TV.

What Is the LG Service Menu?
The service menu is a hidden engineering interface built into every LG TV. It gives technicians access to advanced functions missing from the standard settings: factory reset, key lock control, hotel mode, USB toggles, diagnostics, and white balance.

LG's Two Hidden Menus: EZ-Adjust and InStart
Most LG TVs actually hide two separate engineering menus, not one. The EZ-Adjust menu (password 0413 on most models) is the technician menu: white balance, ADC calibration, and panel options live here. The InStart menu (often 0000 or 0413) is the installer menu: hotel/hospitality mode, power-on channel, and region settings. On older LCD models you reach EZ-Adjust by holding MENU on both the remote and the TV panel until it appears; on webOS models the same combo usually opens InStart. Knowing which menu you are in matters — a factory reset in EZ-Adjust behaves differently from the shipping reset in InStart.
Safety Warnings: Read Before You Enter
The service menu is a professional tool. Follow these rules to stay safe:
- Never save a value blindly. Change one setting at a time and check the effect first.
- Photograph the original values before touching anything, so you can restore them later.
- Leave panel, tuner, and voltage settings alone — wrong entries can stop the TV from starting.
- If anything behaves strangely, unplug the TV for 10–15 minutes and plug it back in; this clears most accidental changes.
How to Open the LG Service Menu
Different LG models respond to different key combinations. Start with Method 1 and work downward until the menu appears.
Method 1: Hold OK on the Remote
Press and hold the OK button on the original LG remote for several seconds. On many LCD and LED models the service menu opens directly — no password needed.
Method 2: Remote + TV Panel Button Combo
Hold the OK (or MENU) button on the remote and the matching button on the TV's own panel together for 10–30 seconds. This combo works on most LG models, including webOS Smart TVs.
Method 3: The Password Prompt Method
Press the MENU button on the remote repeatedly until a password entry screen appears, then enter one of the passwords from the list below.
Which Remote to Use for the Combos
All three methods need the TV's own LG remote — and specifically one with physical OK and MENU buttons. The wand-style Magic Remote that ships with many webOS TVs has an OK wheel-press but no MENU button, so the password-prompt method (Method 3) needs the plain standard IR remote — if your LG came with both remotes in the box, use the standard one for these combos. Universal or programmable remotes often fail on Methods 1 and 2 because a held OK button registers as repeated short presses instead of one long hold. Two details that matter: put in fresh batteries first, and hold the buttons for the full 10–30 seconds without letting go — releasing early is the most common reason a combo "doesn't work" on the first try.
LG Service Menu Password List
When a method triggers the password prompt, try these codes in order — 0413, 0000, 7777, and 8741 cover most models:
- 0413 — works on most LCD / LED models (try first)
- 0000 — common on many older and newer models
- 7777 — used on several LCD and plasma series
- 8741 — various LCD models
- 8878 — many LED series
- 8743 — various LCD models
- 1147 — universal fallback code
- 2008 — later model series
- 1234, 2200, 1111, 0110 — selected regional models
Useful Things You Can Do Inside
Perform a True Factory Reset
The service menu's Factory Reset / Restore can wipe the TV deeper than the normal settings reset — ideal when the standard menu is unreachable or the panel keys are locked. See also our TV factory reset guide.
Unlock Panel Key Lock
If the TV's own buttons are locked, set the Key Lock / Panel Lock option to Off — the panel buttons work again immediately. Our LG panel key lock guide covers the full procedure.
Enable Hotel Mode
Hotel Mode locks the TV into a managed configuration — guests can't rescan channels or disturb your setup. It is equally handy at home to keep children from changing settings.
Turn On USB Media Support
Some LG models ship with USB playback disabled. In the service menu, find the USB option and switch it ON — afterwards, any USB drive plays videos, photos, and music through the TV's media player.
Reset a Forgotten Parental PIN
Locked out by a parental PIN you don't remember? The service menu lets you reset or clear it without knowing the old one — find the lock section and follow the on-screen reset option. For a PIN-only reset outside the service menu, our TV PIN reset guide covers the full walkthrough.
Common LG Faults That Point to the Service Menu
Certain symptoms are service-menu territory. A key-lock icon that never clears means the panel lock is stuck on — the "Unlock Panel Key Lock" section above covers the fix. A TV bought second-hand that shows hotel or hospitality messages is still in InStart installer mode; open it and turn Hotel Mode off. An upside-down picture after a main-board replacement is the classic mirror/flip option set for the wrong panel — fix it in EZ-Adjust rather than replacing the board. And if USB playback is grayed out on an older LG LED, the USB toggle in the service menu is very often the reason — enable it once and the port works normally. For model-specific mirror options, our TV panel mirror codes guide covers the full list.
Troubleshooting
The menu won't open at all
New webOS models often need the original LG remote — universal remotes lack the right buttons. The trigger also varies by model year, so try all three methods plus the full password list.
The menu opens but I can't navigate it
Use the arrow keys to move, OK to select, and the number keys to adjust values. On some models the Back button saves and closes the section. To leave, press EXIT or Power.
The Menu Keeps Closing on Its Own
On several LG series the service menu has a short inactivity timeout — pause too long and it exits by itself, sometimes after only 20–30 seconds. Move through it deliberately, and if it drops out, simply re-enter; the timer resets each time. Also watch the Back button: on some models pressing it one level too far exits the whole menu instead of going up one screen — use the arrow keys to navigate and EXIT when you are finished. If a value you changed seems to revert after you leave, the menu may need an explicit save: look for a "Store" or "Save" entry in that section, or back out through the same path you entered, before pressing EXIT. And if the menu re-opens on a different top-level screen than last time, that is normal — EZ-Adjust and InStart each remember their last page independently.
Frequently Asked Questions
Will opening the service menu void my warranty?
Simply opening it does not — but changing values can, and unauthorized adjustments may be detected during warranty service. If your TV is under warranty, contact LG support first.
What is the default LG service menu password?
There is no single default. Try the first four passwords in the LG Service Menu Password List above.
Can I damage my TV in the service menu?
Yes, if you change panel, tuner, or voltage values carelessly. Stick to the features above and photograph the originals first.
Do these methods work on LG webOS Smart TVs?
Yes — the remote-plus-panel combos (Method 2) work on most webOS models, and the password list applies too. Start with the first passwords in the list above.
Why does 0413 work on some LG TVs but not others?
0413 is LG's classic technician password, so it opens EZ-Adjust on most LCD and LED models from roughly 2008–2018. Newer webOS sets sometimes expect 0000 for the installer menu instead, and very old CRT models used 8741. If none work, the set may be a regional variant — try the full list above, including 7777 and 8878.
I changed a value and now the TV won't start. What do I do?
First, unplug the TV for 15 minutes— many LG models drop unsaved changes on a full power cut. If it still won't boot, re-enter the service menu with the method you used before and restore the values from the photo you took (this is why that photo matters). As a last resort, the panel-button factory reset in the "Perform a True Factory Reset" section above restores defaults — but it wipes everything, so channels and settings will need setting up again.
I opened the service menu by accident. How do I get out safely?
Press EXIT (or Power on older sets) without changing anything — if you did not alter a value, nothing has changed. If you are unsure whether you nudged something, the safest move is the power-cycle: turn the TV off, unplug it for 10–15 minutes, and plug it back in. This clears accidental in-memory changes on many models. If the picture looks wrong afterwards, run the factory reset described in the "Perform a True Factory Reset" section above, then set your picture up again.
Do these service menu methods work on LG OLED TVs?
Yes — OLEDs run webOS, so the OK-hold and remote-plus-panel combos still open the InStart menu on most models. The difference is what you find inside: OLED sets expose different options, such as pixel refresher counters and panel-care settings, and hide others. The classic EZ-Adjust tools, including white balance, still sit behind 0413 on many OLEDs. The same rules apply — photograph every original value before touching anything, and stay out of the OLED-specific panel and driver sections: wrong values there can trigger compensation-cycle faults that only a service center can clear.
Open the right menu for your model, photograph every original value before changing anything, and leave panel, tuner, and voltage settings alone. The password list and the three methods above cover most LG sets without needing any other code.
