How to Connect Alexa to LG Smart TV (ThinQ Guide)

Connect Alexa to your LG ThinQ TV via the LG ThinQ Alexa skill — link accounts, discover devices, and control by voice.

LG's smart TV lineup has come a long way. The ThinQ platform, which powers most LG Smart TVs released from 2018 onward, includes native Alexa integration that goes well beyond simple power on/off commands. If you've been fumbling for the remote just to turn down the volume or switch inputs, you're about to free your hands for good. This guide walks you through every method — from the official ThinQ skill to IR blaster workarounds — so you can talk to your LG TV no matter what model you own.

Is Your LG TV Compatible with Alexa?

Before you spend twenty minutes troubleshooting a connection that was never going to work, check your TV's compatibility. LG officially supports Alexa on ThinQ-enabled Smart TVs from 2018 and later. That includes C-series, B-series, G-series OLED models and the QNED and NanoCell 4K lines. Older WebOS TVs from 2016 and 2017 have limited support and may not be able to use the full ThinQ skill feature set.

To verify your model, press the Settings (gear icon) on your LG remote, then go to All Settings > General > About This TV. Look for the WebOS version — WebOS 4.0 or higher generally supports ThinQ and Alexa. If your TV shows WebOS 3.5 or below, jump ahead to Method 2, which covers IR blaster control through a compatible Echo device.

Also confirm that your TV is connected to the same Wi-Fi network as your Echo device. Mixed-network setups — where the TV is on a 5GHz band and the Echo is on 2.4GHz — don't cause pairing issues between Alexa and LG ThinQ (that link is cloud-based), but they can occasionally trigger lag in command execution.

Method 1 — LG ThinQ Alexa Skill

This is the recommended approach for any compatible LG ThinQ TV. The LG ThinQ skill connects your LG account to Alexa's cloud, letting you issue commands through any Echo device in your home — or even via the Alexa app on your phone. Here's how to set it up step by step:

Step 1: Create or Log Into Your LG Account

Open the LG ThinQ app on your smartphone (available on Android and iOS). Sign in or create a free LG account if you haven't already. Inside the app, add your TV by tapping the + icon and following the on-screen pairing instructions. Your TV and phone must be on the same Wi-Fi network at this stage.

Step 2: Enable the LG ThinQ Skill in Alexa

Open the Alexa app on your phone. Tap More at the bottom right, then go to Skills & Games. Search for LG ThinQ and tap Enable to Use. You'll be redirected to LG's login page — sign in with the same account you used in the ThinQ app. Once authorized, return to Alexa.

Step 3: Discover Devices

After enabling the skill, tap Discover Devices — or simply say "Alexa, discover my devices." Within 30 seconds, your LG TV should appear in the Alexa app under Devices > TVs. If it appears under a generic name like "LG TV," you can rename it to something friendlier like "Living Room TV" for easier voice commands.

Step 4: Test a Command

Try saying: "Alexa, turn on the Living Room TV." If the TV powers on, you're connected. If not, double-check that the TV is on the same LG account, and that the ThinQ app shows it as online.

DomineTec Tip: After pairing, go to your LG TV's Settings > General > AI Service > AI ThinQ and make sure "Connect to Alexa" is toggled on. Some firmware versions require this to be activated manually on the TV side for the full command set to work.

Method 2 — Echo with IR Blaster Control

If your LG TV doesn't support ThinQ — or if the skill-based approach keeps failing for you — there's a hardware workaround using an Echo device with a built-in IR blaster. As of 2026, the Echo Hub and older Echo (4th gen) include an IR blaster that can mimic your LG remote's infrared signal.

Here's how to set it up:

1. Open the Alexa app and go to Devices > Add Device.
2. Select TV, then Other.
3. Choose Use IR Remote and follow the on-screen pairing wizard.
4. Point your original LG remote at the Echo device and press the buttons it asks you to — this teaches Alexa the IR codes.
5. Once trained, rename the TV and start using voice commands.

Keep in mind: IR blaster control is more limited than ThinQ integration. You can control power, volume, and some basic inputs, but app launching and smart features like adjusting picture mode require ThinQ. Still, for older LG TVs, it's a solid fallback. This approach is similar to how you can connect Alexa to Samsung TVs using SmartThings — both leverage dedicated skills for full functionality.

Voice Commands for LG ThinQ TV

Once connected via the ThinQ skill, you unlock a surprisingly deep set of voice commands. Here are the most useful ones, organized by category:

Power and Volume

• "Alexa, turn on the Living Room TV."
• "Alexa, turn off the TV."
• "Alexa, set the TV volume to 20."
• "Alexa, mute the TV."
• "Alexa, unmute the TV."
• "Alexa, turn up the volume on the TV."

Input and Channel Control

• "Alexa, change the TV input to HDMI 1."
• "Alexa, change the channel to 5."
• "Alexa, go to the next channel."

App Launching (ThinQ Only)

• "Alexa, open Netflix on the Living Room TV."
• "Alexa, open YouTube on the TV."
• "Alexa, open Prime Video on the TV."

Playback Controls

• "Alexa, pause the TV."
• "Alexa, play on the TV."
• "Alexa, rewind the TV."

Troubleshooting Connection Issues

Even with a compatible TV and the correct skill enabled, things don't always go smoothly. Here are the most common issues and exactly how to fix them:

Alexa Can't Find the TV During Device Discovery

This usually means the LG account linked in the Alexa skill doesn't match the account tied to your TV in the ThinQ app. Open the Alexa app, go to Skills & Games > Your Skills > LG ThinQ, tap Settings, then Disable Skill. Re-enable it and sign in carefully with the correct LG credentials. Then run discovery again.

Commands Work Sometimes But Fail Randomly

This is almost always a network issue. LG ThinQ requires a stable internet connection on the TV side — if your TV is in a Wi-Fi dead zone, commands will time out. Try moving your router closer, adding a Wi-Fi extender, or connecting the TV via Ethernet if your LG model has an RJ-45 port (most OLED and premium 4K models do).

TV Turns On But Won't Respond to Volume or Input Commands

Some LG TVs require you to enable Simplink (HDMI-CEC) for full Alexa control. Go to Settings > General > HDMI Settings > Simplink and toggle it on. This unlocks volume and input switching through the HDMI control protocol.

The Skill Was Working But Suddenly Stopped

LG occasionally pushes firmware updates that reset ThinQ preferences. After any major TV firmware update, open the ThinQ app, confirm the TV is still listed and online, then re-run device discovery in Alexa. Usually that's all it takes.

Alexa vs Google Home on LG ThinQ

LG ThinQ supports both Amazon Alexa and Google Home, so if you're debating which assistant to use, here's an honest breakdown:

Alexa on LG ThinQ offers more granular control over smart home routines. If you have other Alexa-compatible devices — smart bulbs, plugs, locks — tying everything together through one assistant creates a more seamless experience. Alexa's routine builder is also more mature, letting you chain TV actions with other devices. For example: "Alexa, movie time" could dim your Philips Hue lights, lower the blinds, and turn on the TV to HDMI 1 — all in one command.

Google Home on LG ThinQ shines if you're already in the Google ecosystem — using Chromecast, Nest speakers, or Android phones. Google's natural language processing tends to handle freeform requests slightly better (like "play Stranger Things on Netflix on the living room TV"), but for structured smart home control and routines, Alexa has the edge.

You don't have to choose one and abandon the other — LG ThinQ supports both simultaneously. But for dedicated smart home users, having a single primary assistant keeps routines simpler and avoids conflicts when multiple devices respond to the same wake word.

FAQ

Do all LG Smart TVs work with Alexa?

No. Only LG ThinQ-enabled Smart TVs from 2018 and later officially support the LG ThinQ Alexa skill. Older WebOS models may work with limited IR blaster control but won't have app launching or smart features via voice.

Can I control my LG TV with Alexa without the ThinQ app?

The LG ThinQ app is required to initially link your LG account and register the TV. Once that's done, you can control the TV through Alexa without opening the ThinQ app again — but the initial setup step can't be skipped.

Why does Alexa say "LG TV is not responding"?

This usually means the TV is in a deep sleep mode, the LG account session has expired, or there's a network connectivity issue on the TV side. Wake the TV manually, re-open the ThinQ app to confirm it shows as online, then retry.

Can Alexa open specific apps on my LG TV?

Yes — with the ThinQ skill, Alexa can open major streaming apps like Netflix, Prime Video, Disney+, and YouTube. The exact apps available depend on which apps are installed on your LG WebOS version and whether LG has added voice-launch support for that app.
