Smart TVs are evolving fast, and the LG C3 OLED TV is leading the charge in 2025. With ultra-thin bezels, OLED evo brightness, and now deeper integration with voice assistants like Amazon Alexa, you can control your home theater experience hands-free.
Whether you want to switch inputs, launch Netflix, or dim your lights using just your voice, this guide will walk you through how to set up Alexa on your LG C3 OLED TV step-by-step.
What You Need Before Setup
LG C3 OLED TV (2023 or newer)
Amazon Alexa account + app
LG ThinQ app (on your smartphone)
Wi-Fi connection
Optional: Amazon Echo speaker (if you want full voice assistant presence nearby)
Step-by-Step Alexa Setup on LG OLED
Step 1: Sign Into LG ThinQ App
Download ThinQ from the App Store or Google Play
Sign in with your LG account (or create one)
Connect your LG TV to the ThinQ app
Step 2: Enable Alexa on Your LG TV
On your LG C3 OLED remote, press the Settings (gear) button
Navigate to All Settings > General > Devices > Voice Assistant
Select Alexa (you may see options for Google Assistant or None)
Step 3: Launch Alexa App on Your Phone
Open Alexa > Tap “More” > “Skills & Games”
Search for LG ThinQ skill
Tap “Enable to Use” > Sign in to your LG account
What Can Alexa Do on LG C3 OLED?
With Alexa successfully linked to your LG TV, you can now:
Launch apps: “Alexa, open Netflix on LG TV”
Adjust volume: “Alexa, set volume to 25 on LG TV”
Turn TV on/off: “Alexa, turn off the living room TV”
Change inputs: “Alexa, switch to HDMI 1”
Use routines: “Alexa, movie night” (TV + lights + audio)
Tips for Smooth Alexa Experience
Name your TV: Change device name in the ThinQ app to “Living Room TV” for easier voice recognition
Update firmware: Make sure your LG C3 OLED and Alexa app are both updated
Re-link if needed: If Alexa stops responding, disable and re-enable the LG ThinQ skill in the Alexa app
Does Alexa Work Without an Echo Speaker?
Yes! The LG C3 OLED includes Alexa Built-In. This means you don’t need a separate Echo speaker. Just speak into the LG Magic Remote (microphone button) or use the TV’s integrated microphones (if enabled).
However, using an external Echo speaker provides far-field mic support, custom routines, and tighter smart home integration.
Common Troubleshooting Tips
TV Not Responding to Alexa?
Reboot your TV and router
Ensure LG TV is named properly in Alexa app
Make sure your TV and phone are on the same Wi-Fi network
Voice Command Delay?
Reduce number of smart devices with similar names
Prioritize LG TV in Alexa groups

Setting up Alexa on your LG C3 OLED turns your already premium OLED display into a voice-powered home theater centerpiece. From hands-free control to multi-device routines, Alexa + LG gives you smart convenience without the need for additional remotes or clunky menus.
