Xiaomi Mi TV 4

Android TV

all possible ways of including

Many owners face a situation where Xiaomi TV 4 does not respond to the remote, power button or displays a black screen with backlight, the reasons range from dead batteries in the remote to critical firmware errors. It is important to understand that not all methods are universal - some are only suitable for specific versions of the TV (for example, Mi TV 4A, 4S or 4X).

1. Checking the obvious: remote, socket and cables

Start with the basic checks - they take a minute, but eliminate 60% of false problems.Most often, the Xiaomi Mi TV 4 won't turn on because of:

• 🔋 Discharged batteries in the remote – even if the indicator is glowing, the voltage may not be enough to transmit the signal.
• 📺 Pulled power cable – check if it sits tightly in the connector on the back of the TV.
• ⚡ Faulty socket – connect another appliance (like charging your phone) to make sure the voltage is applied.
• 🔌 Damaged network cable – inspect it for bending or melting.

If the remote is not working, try turning on the TV with the power button on the body (located on the side or bottom, under the Mi logo). Press and hold it for 10-15 seconds, sometimes this resets the hover system. If the button does not respond, move to the next step.

Important! On some Xiaomi TV 4 models (e.g. 4S 55), the power button is combined with an indicator, and when pressed, it should light up in red or white – if this does not happen, the problem may be in the power supply.

2. Reset settings through the service menu (without remote)

If the Xiaomi TV turns on but hangs on the logo or shows a black screen, a hardware reset will help. This method works even without a remote control - a button on the case is enough.

1. Turn off the TV (take the plug out of the socket).
2. Press and hold the power button on the body.
3. Without releasing the button, connect the TV to the outlet.
4. Hold the button for another 30 to 40 seconds until the Recovery Mode appears.

From the recovery menu, select Wipe Data/Factory Reset (use volume buttons for navigation, power button for confirmation). Once reset, the TV will restart and return to factory settings. Attention: this method deletes all installed apps and accounts!

Make sure the TV is off the socket |

Connect power without releasing the button |

Wait for the Recovery menu to appear (up to 40 seconds)-->

⚠️ Attention: On Mi models TV 4X With an Amlogic processor, prolonged retention of the power button can lead to a transition to Fastboot mode. If the screen appears to say Fastboot Mode, release the button and repeat the procedure.

3. Update firmware via USB (if the TV doesn't boot)

If the reset didn't work, and the TV is hanging on the Mi screensaver, the problem could be the damaged firmware, in which case manual flashing through the screen will help. USB-You're gonna need a storage device:

• 🖥️ Computer with Internet access.
• 💾 Flash drive up to 8 GB (formatted in FAT32).
• 📁 Official firmware for your model (you can download it on the Xiaomi Firmware website).

Firmware instructions:

1. Download the archive with the firmware and unpack it. The file should be called update.zip.
2. Copy update.zip to the root directory of the flash drive (not to the folder!).
3. Put the flash drive in. USB-TV port (preferably to port) USB 2.0, if there is one).
4. Press the power button on the case and connect the TV to the outlet.
5. Hold the button until the update menu appears (usually in 20–30 seconds).
6. Select the Apply update from USB and confirm the installation.

It takes 5-10 minutes to update, don't disconnect the TV from the network, don't remove the flash drive until it's fully rebooted, and if the firmware is interrupted, the TV can turn into a brick.

Checking the power supply and capacitors

If the Xiaomi Mi TV 4 is not showing signs of life (the indicator does not burn, does not respond to buttons), the problem may be in the power supply.

• 💥 The TV is spontaneously turned off.
• 🔌 The indicator flashes red, but the screen does not turn on.
• 🔥 The power supply smells like a smog.

For diagnosis:

1. Turn off the TV.
2. Remove the back cover (a cross screwdriver will be required).
3. Examine the power supply for swollen capacitors (they look like barrels with a convex top).
4. Check the fuse (usually located next to the network connector) – if it is blackened or burnt out, it needs to be replaced.

If you don't know electronics, you should go to the service, but you can do it yourself by buying a similar capacity (for example, 1000 capacitors). µF 16V). The cost of repair in the service will cost 1500-3000 rubles, while condensers cost 50-200 rubles per piece.

⚠️ Warning: Working with a power supply is dangerous - even after being disconnected from the grid, capacitors can store charge! Don't touch the board with your bare hands and use isolated tools.

💡

If the TV turns on after only a few attempts, it is a sign of unstable power supply. Try to connect it through a network filter or voltage stabilizer - this can prolong the life of the power supply.

5. Including through ADB (for power users)

If the Xiaomi TV is turned on but hangs on the boot screen, you can try restarting the system via ADB (Android Debug Bridge), a method that requires a computer and basic command line knowledge.

Instructions:

1. Install ADB Tools on your computer.
2. Connect the TV to the PC via USB-port (use a cable with data transmission support).
3. Open the command line (cmd) and type: adb devices If the TV is determined, execute the command to reboot: adb reboot

If the adb device command does not show the device, check:

• 🔌 Is the TV connected to the same Wi-Fi as the computer (for wireless) ADB).
• 🔧 Is debugging on-line USB in the settings of the TV (Settings) → On TV. → Build Number – Press 7 times to activate Developer Mode).

If the TV doesn’t respond to ADB, but the indicator is on, try the forced reboot command:

adb shell reboot -p

💡

ADB-The only way that teams work is if the TV system is partially loaded, and if the screen is black and there's no response to the buttons, this method won't work, you need to run the firmware through the screen. USB iron-repair.

6. Hardware reset via service buttons

Some Xiaomi Mi TV 4 models (e.g., 4X and 4S) have a hidden button combination to completely reset, which works even if the TV is not turned on:

1. Turn off the TV.
2. Press the power button and the volume reduction button (on the body).
3. Connect the TV to the outlet without releasing the buttons.
4. Hold them for 20 to 25 seconds until the reset menu appears.
5. Select Factory Reset and confirm the action.

This method resets all settings, including those tied to Xiaomi and Google accounts, and after the reboot, the TV will prompt you to set it up as new.

Note: On models with an MTK processor (e.g. Mi TV 4A), the combination may be different – instead of using the volume button, use the menu login button (if you have one on the case).

7.When to contact the service: signs of serious malfunctions

If none of the methods worked, the problem may be a hardware breakdown.

• 🔥 The power supply unit makes extraneous sounds (squeaking, crackling) or smells of a burn.
• 💡 The power indicator does not burn at all (even after holding the button).
• 📺 Vertical stripes or artifacts appeared on the screen (a sign of a matrix or video processor malfunction).
• 🔌 The TV turns on but immediately turns off (cyclical reboot).

The cost of repair in official Xiaomi services:

Before visiting the service, save a check or a warranty card – if the TV is warranted (usually 12-24 months), repairs can be free. Also check if there were any spikes in voltage on the network – if the problem occurred after a thunderstorm, it can be an insurance event.
