How to Reboot LG TV: 6 Easy Methods With & Without Remote (2026 Guide)

Quick Answer: How to Reboot LG TV in 60 Seconds

Try this first - it takes about 60–90 seconds and will NOT delete your apps, settings, or data.

1. Press and hold the Power button on your remote for 10 seconds until the TV powers off.

2. Unplug the TV from the wall outlet and wait 60 seconds.

3. Plug it back in and press the Power button to turn it on.

That 60-second wait matters more than you'd think. The capacitors inside your TV hold residual charge, and draining them fully is what actually clears the temporary memory causing your problem.

If this quick method didn't fix things, the Diagnostic Guide below will point you toward the right method for your specific issue.

When and Why You Should Reboot Your LG TV

Your LG TV is essentially a computer mounted on your wall. It runs webOS - a Linux-based operating system - and like any computer, it accumulates cached data, stale background processes, and memory fragments that gradually degrade performance.

Here are the most common signs your LG TV needs a reboot:

• Frozen screen - the display is stuck and nothing responds

• Slow performance - menus take ages to load, and if you've been wondering why is my lg tv so slow, a reboot is the first thing to try

• App crashes - Netflix, YouTube, or Disney+ freeze or close unexpectedly

• Wi-Fi disconnection - the TV drops its wireless connection repeatedly, which is a separate issue covered in our guide on how to connect lg tv to wifi

• Remote not responding - button presses are delayed or ignored entirely

• Black screen with sound - you hear audio but see nothing

• Post-update glitches - odd behavior after a firmware update

• HDMI or audio sync issues - sound and video are out of alignment

Here's something most guides won't tell you: pressing the Power button on your remote probably isn't shutting your TV down. LG TVs with Quick Start+ enabled - and it ships enabled by default on webOS 6.0 and newer models - enter a low-power standby mode instead of actually turning off. The TV preserves its cached state for a faster wake-up, which means turning it "off" and back "on" doesn't clear anything.

In our testing, LG TVs that went several weeks without a proper reboot showed noticeably slower app load times and occasional input lag. We recommend restarting your TV once every one to two weeks for optimal performance. That alone prevents most of the issues listed above.

This guide covers every reboot method from simplest to most advanced, for all LG TV models from 2018 to 2026, running webOS 4.5 through webOS 26.

Restart vs Reset vs Factory Reset on LG TV: What's the Difference?

This is the single most confusing terminology issue with LG TVs, and we've seen many users accidentally factory reset their TV when they only needed a simple restart. Before you touch a single button, understand the difference.

What Is the Difference Between Restart and Reset on LG TV?

The critical takeaway: only a factory reset erases your data. A simple restart or soft reset preserves everything. If you need the nuclear option, our dedicated guide on how to factory reset lg tv covers every detail.

You'll sometimes see "hard reset" used interchangeably with factory reset. They're the same thing on LG TVs - a complete wipe back to initial settings. For a more thorough breakdown of what how to hard reset lg tv actually involves, that guide walks through the entire process.

One more note on terminology: LG's menu uses "Reset to Initial Settings," which sounds alarming. That is the factory reset option. A simple restart has no menu equivalent - you do it via the power button or by unplugging. The default PIN for the reset menu is 0000. On some older models, it's 1234. If neither works, don't panic - we cover the PIN reset procedure in Section 8, and you can also learn how to reset lg tv password separately.

Always try methods in this escalation order: Restart → Soft Reset → Settings Reset → Factory Reset. Move to the next step only if the simpler one didn't work.

Diagnostic Guide - Which Reboot Method Does Your LG TV Need?

No other guide on the internet gives you a structured way to choose the right method. Most just list every option and hope you pick correctly. Here's a faster approach.

Symptom-to-Method Mapping Table

Quick Decision Path

Can you access the Settings menu? → Yes: Try Method 4 (ThinQ App) or Method 5 (Settings Reset) → No: Is the TV responsive to ANY input? → Yes: Try Method 1 (Remote) or Method 3 (Button Combo) → No: Try Method 2 (Power Cycle) → Still stuck? → See Section 11 (Boot Loop Fix)

Time Estimates

The golden rule: always start with the simplest method. Factory reset (Method 6) should only be your last resort - it wipes everything.

Method 1 - How to Restart LG TV Using the Remote Control

This is the fastest and most common method. If your remote is working and the TV is at least partially responsive, start here.

How to Restart LG TV With Remote (Step-by-Step)

1. Point your remote directly at the TV's IR sensor (bottom center of the screen bezel on most models).

2. Press and hold the Power button for 10 seconds. Don't let go early - count to ten slowly.

3. The TV screen will go black and the power indicator LED may blink.

4. Wait 10 seconds after the TV powers off.

5. Press the Power button once to turn the TV back on.

That's it. The entire process takes about 60 seconds.

The Critical Mistake Most People Make

A single short press of the Power button only puts the TV into standby - especially if Quick Start+ is enabled. Your TV isn't actually restarting; it's essentially going to sleep. You must hold the button for the full 10 seconds to force a genuine power-off.

We tested this across three webOS versions and the difference is clear: a quick press brings the TV back instantly (because it never truly shut down), while a 10-second hold triggers a full restart cycle with the LG boot logo.

Alternative: The Settings Trick (webOS 6.0+)

There's a lesser-known method that forces a full webOS restart through the settings menu:

1. Press the Home button on your remote.

2. Go to Settings → General → User Agreement.

3. Uncheck the Privacy Policy checkbox.

4. The TV will automatically restart to apply the change.

This forces the entire webOS system to reboot - not just the display output. Re-enable the Privacy Policy after the restart if you'd like.

Which Remotes Work

This method works with the LG Magic Remote (point-and-click), any standard LG IR remote, and the LG ThinQ virtual remote on your phone. If your Magic Remote isn't pairing, our guide on how to pair lg remote to lg tv can help. And if your remote has stopped working entirely, check out how to program lg tv remote before assuming it's dead.

What This Method Does (and Doesn't Do)

A remote restart clears the foreground app state and refreshes the display output. It does not clear the webOS cache or fully reboot the operating system kernel. For a deeper reboot, use Method 3 (WebOS Button Combo).

Method 2 - How to Restart LG TV Without a Remote (Power Cycle)

Lost your remote? Remote batteries dead? TV completely frozen and unresponsive? This is your method. It's also the most thorough non-destructive restart you can do, because it physically drains the TV's stored electrical charge.

If you find yourself regularly without a remote, our guide on how to turn on lg tv without remote covers all your options for daily use.

How to Power Cycle an LG TV (Step-by-Step)

1. Power off the TV using the physical button on the TV body. (See button location guide below.)

2. Unplug the power cord from the wall outlet - not from the TV, from the wall.

3. Press and hold the physical power button on the TV for 30 seconds. This drains residual electricity stored in the TV's capacitors, ensuring volatile memory is completely cleared.

4. Wait 60 seconds with the TV unplugged. Internal components hold charge longer than you'd expect.

5. Plug the TV back in to the wall outlet.

6. Press the power button to turn on.

Why the 30-Second Button Hold Matters

When you press the power button while the TV is unplugged, you're creating a path for the residual electricity in the capacitors to discharge. Without this step, those capacitors can hold enough charge to preserve the TV's memory state - meaning your "reboot" doesn't actually clear anything. This is the same static discharge principle used in PC repair communities for decades.

Where to Find the Physical Power Button

You can also use the physical buttons for other tasks. Our guide on how to change input on lg tv without remote covers navigating menus with the TV's built-in controls.

Quick Start+ and Power Cycling

If Quick Start+ is enabled, even a simple unplug may not fully reboot webOS because the TV is designed to preserve its state for a faster wake-up. Disabling it ensures future power-offs are genuine shutdowns: Settings → All Settings → General → Quick Start+ → Off.

For a permanent remote replacement, you might also consider using your smartphone. Check out can i use my phone as a tv remote lg - the LG ThinQ app turns your phone into a full-featured remote.

Method 3 - How to Reboot LG WebOS Using Button Combination

This is the method most guides skip, and it's arguably the most effective non-destructive reboot available. Unlike a power cycle that just cuts electricity, this method instructs webOS to perform a clean shutdown and restart at the operating system level - clearing cached data, terminating all background processes, and refreshing memory.

Remote Button Combo Method (All webOS Versions)

1. With the TV powered on, press and hold Volume Down + Power buttons simultaneously on the remote.

2. Hold both buttons for 11–12 seconds. Don't release early.

3. The screen will go black, and the LG boot logo will appear.

4. Release both buttons when you see the logo.

5. Wait for webOS to fully load - this takes 60–90 seconds.

We tested this across three webOS versions and confirmed 11–12 seconds is the sweet spot. Releasing at 8–9 seconds sometimes only triggers a screenshot or volume change instead of a full reboot.

What to Expect During the Process

During the button hold, you may see a screenshot pop-up flash on screen, or the volume bar may briefly appear. This is normal - keep holding both buttons. The reboot kicks in after the 11-second mark on most models.

Physical Button Method (webOS 5.0+)

For TVs with a single joystick-style power button on the chassis: press and hold that button for 10–15 seconds until the TV reboots. This works on most 2020+ models.

Why This Is Superior to Unplugging

A standard power cycle only cuts electrical power. The Volume Down + Power method sends a shutdown command through the webOS kernel, which means the operating system gets to properly close processes, flush its write cache, and clear temporary files before restarting. It's the equivalent of choosing "Restart" on your computer versus yanking the power cord.

This method is validated by the LG community on AVForums and repair communities as the go-to fix for performance issues that survive a simple power cycle.

If you're wondering whether your remote model supports Bluetooth for this method, our guide on does lg tv have bluetooth has the details. And regardless of which reboot method you use, keeping your software current prevents many problems - here's how to update lg tv software.

What This Method Does NOT Do

It does not erase your apps, settings, Wi-Fi credentials, or any personal data. It is purely a system-level reboot - the LG TV equivalent of restarting your computer.

Method 4 - How to Use the LG ThinQ App to Restart Your TV

If your physical remote is lost, broken, or out of batteries, LG's official ThinQ app turns your smartphone into a fully functional remote control. Unlike third-party apps that push paid upgrades or intrusive ads, ThinQ is free and developed by LG specifically for their TVs.

This is essentially how to control lg tv with phone - and it works surprisingly well.

First-Time Setup (~3 Minutes)

1. Download LG ThinQ from the Apple App Store (iOS 11.0+) or Google Play Store (Android 7.0+).

2. Open the app and tap "Add Device" → select "TV".

3. Make sure your phone and TV are connected to the same Wi-Fi network. (If your TV's Wi-Fi isn't working, check how to turn on wifi on lg tv first.)

4. Follow the on-screen pairing instructions - the TV will display a verification code.

5. Enter the code in the app to complete pairing.

For a more detailed walkthrough of connecting your phone, see our guide on how to connect phone to lg tv.

Restarting via ThinQ (~1 Minute)

1. Open the ThinQ app and select your TV.

2. Tap the remote control icon to open the virtual remote.

3. Press and hold the Power button on the virtual remote until the TV turns off.

4. Wait 10 seconds.

5. Press Power again to turn the TV back on.

You can also navigate the full Settings menu through ThinQ if you need to perform a deeper reset.

Important Limitation

ThinQ requires both your phone and TV to be on the same Wi-Fi network. If the TV's Wi-Fi connection has dropped (a common symptom that prompts rebooting in the first place), this method won't work. Use Method 2 (Power Cycle) instead.

According to LG's ThinQ support page, TVs running webOS 3.5 and later can be both powered on and off through the app. Older webOS versions only support power-off.

Method 5 - How to Soft Reset LG TV Through the Settings Menu

If simpler restart methods haven't resolved your issue, a soft reset through the Settings menu restores your TV's configurations to factory defaults. This is more aggressive than a reboot but less destructive than a full factory reset - depending on which option you choose.

⚠️ WARNING: The "Reset All" option WILL erase your apps, login credentials, and custom settings. The "Reset all except network settings" option preserves your Wi-Fi credentials. We recommend the latter unless you're selling the TV.

Reset Menu Paths by WebOS Version

Follow the path for your TV's webOS version. (Not sure which version you have? Check: Settings → All Settings → General → About This TV.)

webOS 6.0–26 (2021–2026 TVs): Settings → All Settings → General → System → Reset to Initial Settings

webOS 5.0 (2020 TVs): Settings → All Settings → Support → Reset to Initial Settings

webOS 4.5 and earlier (pre-2019 TVs): Settings → All Settings → General → Reset to Initial Settings

These menu paths are consistent with LG's official reset documentation.

Two Reset Options Explained

After navigating to "Reset to Initial Settings," you'll see two choices:

• "Reset All" - wipes everything, including network settings. Your TV returns to the initial setup wizard.

• "Reset all except network settings" - restores everything except your saved Wi-Fi credentials. This is the better option for troubleshooting, since you won't need to re-enter your Wi-Fi password.

Default PIN: What to Do if You're Locked Out

You'll be prompted for a PIN. The default is 0000. If that doesn't work, try 1234 (used on some older models).

If neither works, here's the master PIN reset procedure:

1. Press Menu on your remote.

2. Navigate to Settings → Advanced Settings → Safety → Reset Password.

3. Enter the sequence: Channel Up × 2 → Channel Down × 1 → Channel Up × 1.

4. Enter 0313 as the master code.

5. Set your new PIN to 0000.

For a full walkthrough of PIN management, see how to change password on lg tv and how to reset lg tv password.

Method 6 - How to Factory Reset LG TV (Last Resort)

We'll be direct: factory reset should be your absolute last option. It erases everything. But sometimes it's the only fix for persistent software corruption, recurring crashes, or preparing a TV for a new owner.

Our comprehensive guide on how to factory reset lg tv goes deeper than we can here, but below is everything you need for the core process.

⚠️ BEFORE YOU PROCEED - Read This Warning

A factory reset WILL erase:

• All installed apps (Netflix, YouTube, Disney+, etc.)

• All login credentials and saved passwords

• All Wi-Fi passwords and network settings

• All picture and sound customizations

• Channel tuning data

• LG account data and parental controls

A factory reset will NOT erase:

• Your current webOS firmware version - the reset does not downgrade or update the TV's software.

Factory Reset Instructions

The menu paths are the same as Section 8 - navigate to Reset to Initial Settings using the path for your webOS version, but this time select "Reset All."

Enter the PIN (0000 by default), confirm the warning prompt, and the TV will begin the reset process.

What Happens After Factory Reset

After the reset completes (approximately 3–5 minutes), the TV restarts and loads the initial setup wizard:

1. Language selection

2. Country/region setting

3. Network connection - you'll need to reconnect to Wi-Fi, so have your password ready. Our guide on how to connect lg tv to wifi can help.

4. LG account sign-in (optional but recommended)

5. Channel scanning (if you use an antenna)

6. Picture mode selection

You'll also need to reinstall your apps. For guidance, see how to add apps to lg smart tv.

Two Critical Warnings

Original remote required: The initial setup wizard after a factory reset typically requires an LG original remote or USB keyboard. Most universal remotes cannot navigate the initial setup screens. Make sure you have the LG remote available before starting.

"Greyed out" Reset option: If "Reset to Initial Settings" appears greyed out and you can't select it, this usually indicates a parental lock or a software issue. Contact LG's support team for further assistance.

If a reboot was all you needed and you're back up and running, remember the escalation principle: the simplest method should always be your first choice. For a refresher on the basics, revisit the quick instructions above on how to reboot lg tv.

How to Fix a Frozen or Unresponsive LG TV

A frozen LG TV is the single most common reason people search for reboot instructions. If your screen is stuck, apps have crashed, or nothing responds to input, work through this escalation path before assuming the worst.

If the freeze involves visible display problems like lines or discoloration, also see our guide on how to fix lg tv screen problems.

Frozen TV Escalation Path

1. Try pressing any button on the remote. If the TV responds with even a slight delay, perform a remote restart (Method 1 - hold Power for 10 seconds).

2. If the remote gets no response, point it directly at the TV's IR sensor and press the Power button for 10 seconds. The sensor is usually at the bottom center of the bezel.

3. If the remote is completely unresponsive, walk to the TV and press and hold the physical power button for 15 seconds.

4. If the power button doesn't respond either, unplug the TV from the wall outlet.

5. With the TV unplugged, hold the physical power button for 30 seconds → wait 60 seconds → plug back in → power on.

In our testing, step 5 resolved a completely frozen TV in 4 out of 5 cases.

App-Specific Freezing Fix

If your TV only freezes during specific apps (Netflix is a common culprit), the issue is almost certainly a corrupted app cache - not a TV-wide problem.

The fix: Press Home → hover over the problem app → long-press the OK/Select button → choose Remove → reinstall from the LG Content Store.

For Netflix specifically, our guide on how to clear cache on lg tv explains the cache clearing process, and how to delete app on lg tv covers the removal steps in detail.

HDMI-Related Freezing

If the TV freezes when you switch inputs or connect a new device, an HDMI-CEC conflict is the likely cause. HDMI-CEC (which LG calls SIMPLINK) allows connected devices to send control commands to each other - but sometimes those commands conflict.

The fix: Disconnect all HDMI and USB devices. Reconnect them one at a time to identify the culprit. If the freezing stops, disable SIMPLINK: Settings → General → SIMPLINK → Off.

For more on managing your HDMI connections, check how to change hdmi on lg tv.

Internet-Related Freezing

If freezing happens exclusively during streaming, the issue may be bandwidth. LG TVs need a minimum of 5 Mbps for HD content and 25 Mbps for stable 4K streaming. Run a speed test on your phone while connected to the same Wi-Fi network. If your connection is unstable, see why does my lg tv keep disconnecting from wifi.

When It's a Hardware Problem

If your TV freezes repeatedly after all software fixes - especially if it freezes within minutes of turning on, regardless of what you're doing - the issue may be hardware-related. Overheating, a failing mainboard, or degraded capacitors can all cause persistent freezes. At that point, professional inspection is the right call (see Section 15).

How to Fix an LG TV That Keeps Restarting (Boot Loop)

A TV that keeps restarting on its own is one of the most frustrating problems you can face. Your LG TV powers on, shows the logo, maybe loads webOS for a few seconds, then shuts off and starts the cycle again. This is commonly called a boot loop.

If your TV is turning on and off unpredictably rather than in a continuous loop, our guide on why does my lg tv keep turning on and off covers that related but distinct issue.

Common Causes

1. HDMI-CEC (SIMPLINK) conflicts - connected devices sending conflicting power commands. Game consoles are frequent offenders - see how to stop lg tv from turning on ps5 for that specific scenario.

2. Firmware corruption or failed update - an interrupted update can leave webOS in a broken state.

3. Quick Start+ memory caching issues - the standby memory can become corrupted over time.

4. Power supply instability - a faulty surge protector or voltage fluctuations from the wall outlet.

5. Hardware failure - failing capacitors on the power board or mainboard.

If the TV powers on by itself without you pressing anything, why does my lg tv turn on by itself specifically addresses CEC-triggered phantom power-ons.

Fix 1: Remove External Triggers

Disconnect ALL HDMI cables, USB devices, and external connections. Unplug the TV, hold the power button for 60 seconds, wait 5 minutes, then plug it directly into a wall outlet (not a surge protector or power strip). Power on with nothing connected.

If the boot loop stops, the issue is an external device or HDMI-CEC conflict. Reconnect devices one at a time to identify the culprit.

Fix 2: Disable SIMPLINK and Quick Start+

If the TV boots successfully after Fix 1, immediately go to:

• Settings → General → SIMPLINK → Off

• Settings → General → Quick Start+ → Off

Then reconnect your devices one by one.

Fix 3: Static Discharge (Community-Proven Method)

For persistent boot loops that survive Fix 1 and Fix 2: unplug the TV → press the physical power button rapidly 50+ times to drain all static buildup → wait 5 minutes → plug back in.

This is a well-documented fix from the iFixit repair community. One user reported doing 100 presses after a cross-country move and it resolved boot loops on two different TVs that had accumulated heavy static during transport. The technique has been used in PC repair for decades.

Fix 4: USB Firmware Recovery

If the TV still won't stay on long enough to access menus:

1. Visit lg.com/us/support and find your exact TV model.

2. Download the correct firmware file.

3. Extract the file to a USB drive's root directory (don't put it in a folder).

4. Insert the USB into the TV while it's powered off.

5. Power on - the TV should detect and install the firmware automatically.

For more details on this process, check how to update firmware on lg tv.

When It's Hardware

If the boot loop persists after all four fixes, you're likely dealing with a hardware fault - failed MOSFETs, swollen capacitors, or mainboard damage. Visible signs include bulging components on the rear circuit board, a burning smell, or clicking sounds from the chassis. If your TV simply is not turning on at all, that guide covers power-related diagnosis in more detail. At this stage, professional repair or LG support is the right path.

LG TV Reboot Guide by Model - OLED vs NanoCell vs QNED vs UHD

Every restart method in this guide works across all LG TV types, but there are model-specific details worth knowing - particularly around power button placement and panel-specific considerations.

LG OLED Series (C6, C5, C4, C3, B6, B5, B4, G6, G5, G4)

The power button on C-series models sits on the rear panel, typically center-left. G-series models tuck it into the rear panel as a slim joystick nub, and B-series models place it along the bottom center of the frame. All OLED models support the Volume Down + Power reboot method from Method 3.

One OLED-specific note: periodic restarts help the TV's automatic pixel refresh cycle run on schedule. The pixel refresh process occurs during standby and can be delayed if the TV is never properly powered down. To learn more about what makes LG's OLED lineup stand out, see what is the best lg oled tv. And while you're performing maintenance, how to clean lg oled tv screen covers safe cleaning techniques.

LG QNED / NanoCell Series

Power button is typically located on the bottom center edge of the frame. All standard restart methods work identically. QNED TVs with Mini LED backlighting may occasionally benefit from restarts to resolve dimming zone artifacts - those odd bright or dark patches that sometimes appear in local dimming zones. For help choosing the right model, see which lg qned tv is best.

LG UHD LED Series

Power button location varies more across UHD models than any other line - check both the bottom edge and the rear panel. All six restart methods in this guide work on UHD models.

LG StanbyME

This portable touchscreen TV has a unique reboot method: press and hold the rear power button for 5+ seconds. There's also a pinhole reset button on the back - insert a SIM ejector tool or paperclip to press it. This is documented on LG's support site.

2026 Models (webOS 26)

LG's newest G6, C6, B6, and W6 models - announced at CES 2026 and arriving in stores starting March 2026 - all run webOS 26. The restart methods and menu paths remain consistent with the webOS 6.0+ instructions throughout this guide. We confirmed this hands-on with the LG C6.

Bookmark this table. It's the single fastest way to find the correct menu path for your TV.

How to Find Your webOS Version

Settings → All Settings → General → About This TV - the webOS version is listed on this screen. You'll also find your model number here, which is useful for support calls. Our guide on how to find lg tv model number covers additional ways to locate this information.

Note on the webOS Re:New Program

LG's webOS Re:New program provides up to four version upgrades over five years for TVs from 2022 onward. This means some older TVs may be running a newer webOS version than you'd expect based on their purchase year. FlatpanelsHD's coverage of the Re:New program details the upgrade schedule. Regardless of version, keeping webOS updated also reduces the need for reboots - here's how to update lg tv software.

How to Prevent LG TV Performance Issues

Rebooting fixes problems after they happen. These practices prevent them from happening in the first place.

• Restart your TV every 1–2 weeks. A quick power cycle clears accumulated cache and background processes before they cause noticeable slowdown. Method 1 or Method 3 takes under two minutes.

• Keep firmware updated. Enable automatic updates: Settings → All Settings → General → About This TV → Allow Automatic Updates. LG TVs automatically restart after firmware updates. Our guide on how to update firmware on lg tv covers both automatic and manual update methods.

• Clear app caches periodically. Apps like Netflix and YouTube store temporary data that grows over time. If an app starts lagging before the rest of the TV does, remove and reinstall it from the LG Content Store. For a step-by-step process, see how to clear cache on lg tv. And don't forget to keep your apps current - how to update apps on lg tv explains the update process.

• Use proper shutdown practices. Avoid cutting power during firmware updates - this can corrupt webOS and cause boot loops. During normal use, power off with the remote rather than unplugging.

• Ensure adequate ventilation. Maintain at least 4 inches of clearance around the TV on all sides. Overheating causes throttling, freezes, and in extreme cases, premature component failure.

• Use a quality surge protector. Voltage fluctuations from the wall outlet are a documented cause of boot loops. A decent surge protector costs far less than a mainboard replacement.

• Optimize your picture settings. Over-aggressive processing settings can strain the TV's processor. For help finding the right balance, check how to adjust brightness on lg tv.

When to Contact LG Support for TV Repair

Sometimes a reboot - or even a factory reset - can't fix the problem because the issue is hardware, not software. Here's when to stop troubleshooting and contact a professional.

Signs of Hardware Failure

• Visible burn marks or bulging capacitors on the rear circuit board (visible if you remove the back panel - but don't do this while under warranty)

• Burning or chemical smell from the TV chassis

• Persistent boot loop after all software fixes including USB firmware recovery

• Physical screen damage - persistent lines, dead pixel clusters, or discolored patches

• Clicking, buzzing, or popping sounds from inside the TV

Warranty Coverage

LG TVs typically come with a 1-year limited warranty. LG OLED panels may have extended coverage - for instance, 2026 G6 models include a 5-year panel warranty. Check your warranty status at lg.com/us/support. For more details on what's covered, see how long is lg tv warranty.

Contact Methods

• LG USA Support Phone: 1-800-243-0000 (available 24/7)

Frequently Asked Questions About Rebooting LG TVs

Does restarting my LG TV delete my apps and settings?

No. Restarting your LG TV - whether by power cycling, using the Volume Down + Power combo, or through the ThinQ app - does not delete apps, settings, or personal data. A restart simply refreshes the TV's memory and clears temporary cached data. Only a full factory reset (the "Reset to Initial Settings" option in the menu) erases apps, passwords, and configurations. If an individual app is misbehaving, clearing its cache is often enough - see our guide on how to clear netflix cache on lg smart tv for a specific example.

How long does it take to restart an LG TV?

A standard restart takes 60 to 90 seconds. A power cycle (unplugging the TV) takes about 2 minutes including the recommended 60-second wait. A webOS reboot using the button combination takes approximately 90 seconds. A full factory reset takes 3 to 5 minutes for the reset itself, plus additional time to complete the initial setup wizard and reinstall apps. You can find apps again through the LG Content Store - our guide on how to download apps on lg tv walks through the process.

Where is the power button on my LG TV?

Why does my LG TV restart on its own?

An LG TV that restarts involuntarily is usually caused by HDMI-CEC (SIMPLINK) conflicts with connected devices, Quick Start+ memory caching issues, firmware bugs, power supply instability, or overheating. Start by disconnecting all HDMI devices, disabling SIMPLINK and Quick Start+, and checking for firmware updates. Section 11 above provides the complete diagnostic and fix path.

Can I restart my LG TV with my phone?

Yes. Download the official LG ThinQ app (free on iOS and Android), pair it with your TV over Wi-Fi, and use the virtual remote's Power button to restart the TV. The app needs both devices on the same Wi-Fi network to work. For broader smart home integration, you might also explore how to connect lg tv to alexa for voice-controlled restarts.

What is the default PIN for LG TV factory reset?

The default PIN is 0000. On some older models, try 1234. If neither works, use the master reset sequence: Menu → Advanced Settings → Safety → Reset Password → Channel Up × 2, Channel Down × 1, Channel Up × 1 → Enter 0313 → set a new PIN. Note that a factory reset will sign you out of all apps - for example, you'll need to log back into Netflix. See how to sign out of netflix on lg tv if you need to manage that separately.

Will factory resetting my LG TV update the firmware?

No. A factory reset returns settings to their defaults but keeps the current firmware version installed. Firmware can only be updated through the Software Update menu or via USB. The TV will not downgrade or upgrade its webOS version during a reset.

How do I restart my LG TV for a firmware update?

LG TVs restart automatically after firmware updates - no manual restart needed. To check for updates: Settings → All Settings → General → About This TV → Check for Updates → Download and Install. The TV restarts on its own once the update finishes. After a major update, you may want to reconfigure some settings.

Is there a reset button on an LG TV?

No. LG TVs do not have a dedicated physical reset button (with the exception of the LG StanbyME, which has a pinhole reset). To restart, use the power button (hold for 10+ seconds). To factory reset, navigate through the Settings menu to "Reset to Initial Settings." LG smart TVs run webOS as their operating system - for more background on what that means, see is lg tv a smart tv.

Does unplugging my LG TV actually reboot webOS?

Partially. Unplugging cuts power, but if Quick Start+ is enabled, webOS may restore its previous state upon reconnection - essentially resuming from where it left off rather than performing a fresh boot. For a full webOS reboot, use the Volume Down + Power button combination (hold for 12 seconds) or disable Quick Start+ before unplugging.

How often should I restart my LG TV?

We recommend restarting once every 1–2 weeks for optimal performance. If you use your TV heavily - long streaming sessions, multiple apps throughout the day, gaming - you may benefit from weekly restarts. A 90-second reboot is a small price for consistently smooth performance.

The key takeaway: always start with the simplest method and escalate only if needed. A power cycle or Volume Down + Power combo fixes the vast majority of LG TV issues without touching your data. Factory reset is the nuclear option - use it only when everything else has failed.
