Why Xiaomi TV turns on on on its own and how to fix it

Why Smart TV Behaves Like a Poltergeist

You wake up at night from a flickering screen and find that Xiaomi Mi TV 4A or Redmi Smart TV is back on without you? This is not a ghost, but a typical problem of smart TVs on Android TV. According to service centers, up to 15% of Xiaomi TV owners experience spontaneous switching on at least once a year, the reasons are rooted in software failures and hardware features.

In this article, we’ll look at all the possible causes, from the banal “stick” of the power button to the hidden features of Google Assistant and Mi Home that can wake your TV. And most importantly, give step-by-step instructions on how to turn off auto-on forever without calling the service. If your Xiaomi TV has become a “night monster”, read on.

1. "Awakening" by timer: hidden settings Android TV

The most common reason is activated turn-on timers that the user doesn't even know about. Android TV's firmware (and Xiaomi uses a modified version of PatchWall) has a built-in scheduler feature that can trigger:

• 🕒 Scheduled (for example, for recording the airwaves)
• 🔔 When receiving push notifications from apps (YouTube, Netflix)
• 🔄 After software update (TV reboots and “forgets” to turn off)

To check the timers:

1. Go to Settings → Smart Home → Timers and Reminders
2. Remove all active tasks marked “Switch on TV”
3. Turn off the option Automatic Turn on for Updates in Settings → About TV → System Update

Important! On some models (like the Mi TV Q1E), timers are hidden in the Google Assistant menu. To turn them off, say in your voice, "OK, Google, show me my schedule," then delete the unnecessary ones.

2.DU remote control problems: "phantom" signals

If the TV is only turned on when you are around, the remote is to blame. Cheap Chinese remotes (especially from the Redmi TV A Series) often "glue":

• 🔋 Discharged batteries send false commands
• 📶 Interference from other IR devices (air conditioners, lamps)
• 💧 Sticking the Power button due to moisture

How to check:

1. Remove the batteries from the remote for 10 minutes. If the TV doesn't turn on itself, the problem is the remote.
2. Illuminate your smartphone with a Power button (must be visible infrared signal) If the signal is constantly going, the button is stuck.
3. Try to control the TV through the Mi Remote app – if the self-adventure stops, replace the remote.

💡

To avoid interference, stick a piece of black tape on the TV's IR receiver (without completely closing it), which blocks random signals from other devices.

⚠️ Attention: On Mi models TV P1 And the newer one is a Bluetooth remote. If it's buggy, reset it to Settings. → Remote and accessories → Forget the device.

3. firmware failures: when the TV "went crazy"

More than 40 percent of self-inclusions are due to damaged firmware, especially after airborne updates (OTAs).

• 🔄 The TV is turned on and off (cycle)
• 📺 The logo of Xiaomi or Android appears on the screen. TV loaded
• ⚡ Self-inclusion is accompanied by an audible signal (on models with Dolby Audio speakers)

How to fix it:

2. Unpack. ZIP-archive and copy the file update.zip flash drive (format) FAT32).
3. Insert the flash drive into the TV, go to Settings → About TV → System Update → Update via USB.

4.Smart Home and Voice Assistants: Who Wakes Your TV

If you have a smart speaker (like the Xiaomi Mi AI Speaker) or other devices in the Mi Home ecosystem, they may accidentally turn on the TV through:

• 🎤 Voice commands (OK, Google, turn on the TV in the living room»)
• 🤖 Automation in Mi Home (e.g., “Enable TV while driving»)
• 📱 Remote control via Mi Remote app (if one of the household members accidentally clicked on it)

How to turn it off:

1. In the Mi Home app, go to Profile → Settings → Voice Assistant and turn off TV control.
2. In Google Home, remove the TV from the list of devices or turn off the Auto Detect option.
3. Check Automation: Mi Home → Automation → Delete all rules with the TV.

5. Hardware malfunctions: when the "iron" is to blame

If the software methods didn’t help, the problem could be in the hardware:

• 🔌 Faulty power supply - supplies voltage to the motherboard even in the "off" state.
• 🖱️ Sticking the power button on the case (often after wet cleaning).
• 🔋 Bloated capacitors on board (typical for models over 3 years old).
• ⚡ Static electricity – if the TV is near sources of interference (microwave, refrigerator).

Diagnosis:

1. Turn off the TV for 30 minutes, and if the problem disappears after turning on, the power supply is to blame.
2. Light a flashlight on the power button: if it is drowned or dirt is visible under it, clean it with alcohol.
3. Check the capacitors on the board (if you have experience disassembling): bloated or leaking electrolyte - a sign of malfunction.

⚠️ Note: If the Xiaomi Mi TV TV 4S Or older, it's on with cotton or spark, immediately disconnect it from the network! This is a sign of a breakdown of the capacitors - a replacement in the service is required.

💡

Self-exclusion due to hardware problems is often accompanied by extraneous sounds (cracking, squeaking) or flickering of the indicator in the off state.

6.External devices: who else can wake the TV

Connected gadgets can send on signals:

• 🎮 Game consoles (PS5, Xbox: Some models wake up the TV when you upgrade.
