1. The most common causes of spontaneous inclusion

To start with the obvious, Xiaomi TVs don't turn on by themselves, and there's always an external signal behind it (from the remote, router, smartphone) or an internal system command. TOP-5 triggers that are responsible for 90% of cases:

• 📶 Wi-Fi and network commands: The TV receives a turn on signal over a local network (for example, from the Mi Home app or voice assistant).
• ⏰ Hidden Timers: A Scheduled Auto Turn On feature that you could have activated accidentally.
• 🎮 Connected devices: game consoles, sound panels or even USB-The flash drive can wake up the TV.
• 🔋 Power problems: Power surges or a faulty power supply unit causes the system to reboot.
• 🤖 Firmware errors: software bugs (especially in versions) MIUI TV 3.0-4.5) lead to accidental inclusions.

How to check:

1. Remove the batteries from the remote for 10 minutes. If the TV doesn't turn on, it's the remote.
2. Put your smartphone flashlight on the IR receiver (turn on the camera, it sees the IR signal) and if you press the remote, the screen flashes, the signal passes.
3. Install the application on the smartphone IR Remote Tester and check if the remote does not send false commands.
