How to turn on the TV Xiaomi Mi TV 3: all ways and solutions to malfunction

Xiaomi Mi TV 3 remains popular even years after its release — its combination of price, picture quality and functionality on Android TV attracts users. However, many face a basic problem: how to turn on the device if it does not respond to the remote, freezes after the update or does not show signs of life at all. This article will not just list the ways to turn on, but also explain why the TV can ignore your commands, and what to do in unusual situations – from reset to hardware repair.

The Mi TV 3 (L43M5-5A, L49M5-5A, L55M5-5A, etc.) is a backup control system that can be used with both physical buttons on the body and a remote, Mi Remote app or even voice commands, but each method has its own nuances. For example, after updating the firmware, the TV may require a forced reboot, and when the remote is discharged, it will only react to mechanical press. We will analyze all the scenarios, including those that are not written in the official instructions.

Important: If your Mi TV 3 doesn't turn on after a power surge or a fall, check the power supply and cables first, which are the most common cause of dead state, and the rest of the cases require a systematic approach, which we will describe below.

1. Standard inclusion: button on the body and remote

The most obvious way is to use the power button on the TV body, which is on the right side (if you look at the screen) under the Mi logo, or on the bottom frame.

• 🔘 Touch (responds to light touch)
• 🔘 Mechanical (requires clicking presses)
• 🔘 Combined (with backlight indicating standby mode)

Algorithm of action:

1. Make sure the TV is plugged into the outlet (the indicator on the power supply should be red or white).
2. Press the power button with one short press (holding more than 5 seconds triggers reset!).
3. If the screen does not respond, try holding the button for 10-15 seconds, which will force you to restart the system.

The situation is more complicated with the remote control: if the TV does not respond, check:

• 🔋 Batteries (even "fresh" ones can be discharged - try other ones).
• 📶 Direction of the IR transmitter (the remote must "look" at the receiver on the front panel of the Mi) TV 3).
• 🔄 Reboot the remote (remove the batteries for 30 seconds).

Replace your batteries with new ones (even if the old ones are working).

Wipe the IR transmitter with alcohol

Check for no obstacles between the remote and the TV

Press any remote button and look at it through the smartphone camera (the infrared signal should be visible)

If the remote is lost or broken, use the Mi Remote app (available for Android and iOS).

1. Connect your phone and TV to the same Wi-Fi network.
2. In the app, select Add Device → Television → Xiaomi.
3. Follow the instructions on the screen (you may need to enter) PIN-TV-code).

2. Incorporation after updating or resetting

Updating the firmware on Mi TV 3 sometimes results in a "hang" on the Mi logo or black screen. This is not always critical: the system can reboot up to 10 minutes (especially when you first turn on after the update).

If the TV's hanging:

1. Turn it off the socket for 30 seconds.
2. Turn it back on and hold the power button for 15-20 seconds until the logo appears.
3. If the download is interrupted, try again or reset to factory settings (see section below).

After resetting (Settings → About TV → Reset), the TV will turn on in initial setting mode.

• 🌍 Choose a language and region.
• 📶 Connect to Wi-Fi (if not working, use an Ethernet cable).
• 🔑 Sign in to Xiaomi account (or skip this step).

Never update.

3. Hardware on-boarding methods (if nothing works)

If Mi TV 3 doesn’t respond to either the button or the remote, the problem may be:

• 🔌 Power supply unit (check the indicator - if not burning, the unit is faulty).
• 🔋 Capacitors on the motherboard (swelling is visible at autopsy).
• 🖥️ Damaged firmware (requires flashing through the USB OTG).

For diagnosis:

1. Turn off the TV.
2. Remove the back cover (a cross screwdriver will be required).
3. Check visually for bloated capacitors or burnt tracks.

💡

If you are not an electronics expert, don’t try to repair the power supply yourself – high-voltage capacitors can retain charge even after being disconnected from the grid!

For compulsory inclusion through the motherboard:

1. Find a connector on the board. CN501 (usually signed POWER_SW).
2. Carefully close contacts 1 and 2 with a screwdriver (this simulates the pressing of the power button).
3. If the TV doesn't respond, the problem is in the board or power supply.

4. Initiation via USB (emergency flashing)

If the TV is not turned on due to damaged firmware, it can be "resuscitated" through the USB-It's a storage device:

1. Download the official firmware for your model from the Xiaomi Support website (choose the version marked Recovery).
2. Unpack the archive and copy the file update.zip rootless USB-storage device (format) FAT32).
3. Disconnect the TV from the network, insert the flash drive into the USB 2.0 port (usually located on the side).
4. Press the power button and plug the TV into the outlet. Hold the button until the recovery menu appears.

On the Recovery Mode menu:

• 🔧 Select Apply update from USB.
• 📁 Specify the file update.zip.
• ⏳ Wait until the process is complete (do not turn off the power supply!).

💡

Flashing over USB erases all user data, including installed apps and settings. Prepare backups of important files in advance (if the TV has been turned on before).

If the recovery menu doesn’t appear, try:

• 🔄 Other USB-drive (some flash drives are not recognized).
• 📌 Rename the firmware file to update.zip (register!).
• 🔌 Use the port USB 3.0 (on some Mi models) TV 3 he's running more stable).

5. Enable via HDMI-CEC (if there is another device)

HDMI-CEC allows you to control your TV through connected devices (set-top boxes, sound bars, etc.) If your Mi TV 3 supports CEC (in settings, this may be called Anyview Cast+ or Mi Link), you can turn it on via:

• 🎮 Player console (PS4/PS5, Xbox – In their settings, turn on the option HDMI Device Link).
• 📺 Android console TV Apple TV (customized HDMI activate Control TV).
• 🔊 Sound panel or receiver with support CEC.

How it works:

1. Connect the device to the TV via HDMI.
2. Turn on the device (for example, the console).
3. The TV should automatically turn on and switch to the appropriate HDMI-entrance.

If the CEC is not working:

• 🔧 Check if the feature is enabled in the settings of the TV (Settings) → System system → HDMI-CEC).
• 🔄 Reconnect. HDMI-cable (sometimes it helps to change the port).
• 📋 Update the firmware of the device connected to HDMI.

6. Diagnosis of malfunctions: when to contact the service

If none of the methods worked, the problem could be hardware.

⚠️ Warning: If the TV is squeaking or cracking when you try to turn it on, immediately disconnect it from the network! This may indicate a short circuit or a break in the power supply. Further attempts to turn on may lead to a fire or permanent failure of the motherboard.

Symptoms requiring professional repair:

Before contacting the service:

• 📸 Take a picture or videotape the symptoms (this will help the master to diagnose the problem faster).
• 📋 Keep a check or warranty card (if the TV is guaranteed, repairs can be free of charge).
• 🔍 Check out service center reviews – some “masters” may impose unnecessary services.

⚠️ Note: If you want to repair the Mi TV 3 on your own, remember: warranty is cancelled when you open the case, and the circuit boards can still have dangerous voltages even after you've disconnected from the network.
