LG TVs may power on unexpectedly due to active power timers, smart home voice assistant commands, or HDMI-CEC settings known as Simplink that trigger devices to wake the display.

Key Points

• LG TVs often wake up automatically because of misconfigured power timers or external devices connected via HDMI-CEC.
• Simplink, LG’s branding for HDMI-CEC, can cause the television to power on whenever a connected device, such as a gaming console, activates.
• Smart home integrations, including Amazon Alexa and Google Assistant, can trigger the TV to turn on via voice commands.
• Users can disable Simplink by navigating to the Device Connection Settings menu within the TV's All Settings interface.
• Checking the Time & Timer menu under General settings allows users to verify and disable any scheduled Power On timers.

Why it Matters

These automatic wake-up issues can lead to unnecessary energy consumption and potential screen burn-in if the TV remains on while the user is away. Understanding these settings allows owners to regain control over their hardware and prevent unwanted power usage.
