Did you press the button on the remote, but the screen of the Xiaomi Mi TV remained black? Or the power indicator flashes, but the image does not appear? This situation is familiar to many owners of smart TVs from Xiaomi — from Mi TV 4A models to flagship Mi TV Q2. The reasons can vary from a banal firmware failure to serious hardware malfunctions. In this article, we will analyze all possible scenarios why the TV does not turn on, and give step-by-step instructions for recovery, from simple actions to complex manipulations with iron.
It's important to understand that if Xiaomi TVs don't respond to commands, it doesn't always mean that they're broken. 60 percent of the time, they're software-solved, without going to the service center. But there are some critical symptoms that you can't ignore. For example, if there's no sign of life after a thunderstorm, it could indicate that the power supply is out of order. We'll teach you how to distinguish between "mild" failures and serious malfunctions and tell you when to call a specialist.
This article is relevant for all Xiaomi Mi TV models, including the 4A, 4S, 4X, 5, Q1, Q2, A2 and others. The instructions are universal, but some devices (such as the Mi TV Stick) may require additional steps – we will mention them too.
1.Primary diagnosis: check power and connections
Before you take down the TV or reset your settings, make sure that the problem isn't the trivial stuff. Start by checking the power supply and the cables.
- 🔌 Check the socket: connect another device to it (for example, charging your phone), if the socket does not work, the problem is not with the TV.
- 🔄 Reconnect the power cable: take the cord out of the TV and the socket, wait 30 seconds and reconnect. Sometimes this drops the getting stuck capacitors in the power supply.
- 🔋 Try another cable: if you have a spare power cord (like a monitor or other TV), use it. The cables wear out over time, especially in places of inflection.
- ⚡ Eliminate power surges: if the TV is turned off during a thunderstorm or after a voltage drop, there is a high risk of damage to the power supply.
If after these manipulations, the Xiaomi TV still doesn’t turn on, move to the next step.
- 🔴 Burning red: TV gets powered but doesn’t start (possible firmware failure or hardware malfunction).
- 🟢 Flashing green: Attempt to start up, but the system can’t boot (often associated with corrupting OS files).
- ⚫ Does not burn at all: there is no power or the power supply / motherboard has failed.
2. Resetting settings through buttons on the body
If the Xiaomi TV doesn’t respond to the remote, but the power indicator is on, try a hard reset, which works even in severe firmware failures, and is suitable for most models, including the Mi TV 4A, 4S, 5 Pro and others.
Find the Power button and Volume button on the TV body, usually on the bottom or sidebar.
- Turn off the TV from the outlet.
- Press the Power and Volume buttons simultaneously.
- Without releasing the buttons, connect the TV to the outlet.
- Hold the buttons for another 10-15 seconds until the Xiaomi logo or recovery menu appears.
If the reset is successful, the TV will restart and prompt you to set up the system from scratch, and importantly, this method erases all user data, including installed apps and saved settings, and if the TV doesn't turn on again after the reset, the hardware may be the problem.

3.Firmware problems: how to reflash Xiaomi TV
One of the most common reasons why Xiaomi TVs don't turn on is because of a broken firmware, which can happen after a failed update, a power outage during software installation, or a virus infection. USB-accumulator.
You'll need:
- 🖥️ Computer with Internet access.
- 💾 USB-drive (flash drive) with a volume of at least 4 GB, formatted in FAT32.
- 🔗 Official firmware for your model (you can download it on the Xiaomi Support website).
Firmware instructions:
- Download the firmware archive and unpack it. The firmware file should have the.zip or.pkg extension.
- Copy the firmware file into the root directory of the flash drive and rename it to update.zip (important: no spaces and special characters!).
- Turn off the TV from the network, insert the flash drive into the USB-port (usually located on the side).
- Press the Power button on the case and, without letting it go, connect the TV to the outlet.
- Hold the button until the recovery menu appears (usually 10-20 seconds).
- In the menu, select Update or Install from USB (manage by volume buttons and Power button confirmation).
The upgrade process will take 5-10 minutes. Do not disconnect the TV from the network during firmware - this can cause the device to completely fail. If the TV does not turn on after the upgrade, try repeating the procedure with another firmware version (for example, an older one).

4. Diagnostics of hardware malfunctions
If the software methods didn’t help, the problem is probably the hardware, and consider the most common hardware malfunctions of Xiaomi TVs and their signs:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The indicator is not on, the TV does not respond to the buttons. | Power supply failure | Replacement of the power supply (sweater iron and experience required) |
| The indicator is on, but the screen is black, there is no sound. | Failure of the motherboard or illumination | Diagnostics with a multimeter, replacement of a board or backlight inverter |
| The TV turns on, but after a few seconds it turns off. | Overheating of the processor or video card | Cleaning from dust, replacing thermopaste |
| Image is there, but no sound. | Damage to audio track or speakers | Checking the plumes of the speakers, replacing the audio module |
| Artifacts on screen (stripes, flickering) | Failure of the matrix or video processor | Replacement of the matrix or repair of the graphics chip (expensive) |
To diagnose hardware problems, you'll need to disassemble the TV, which is a risky procedure, because you can damage the plumes or lose the warranty (if it's still valid), if you're not sure about yourself, you'd better go to the service.
- 🔍 Condenser check: Bloated or leaky capacitors on the power supply or motherboard are a common cause of malfunctions. You can replace them yourself if you have a soldering iron.
- 🧹 Dust cleansing: dust buildup on radiators causes overheating. Use a compressed air spray or a soft brush.
- 🔌 Trail check: broken or broken plumes can cause no image or sound. Carefully reconnect them.
💡
Before disassembling the TV, take a picture of the location of all the plumes and connectors, which will help to properly assemble the device back and avoid new problems.
⚠️ Warning: When disassembling a Xiaomi TV, be careful with capacitors — even after disconnecting from the network, they can store charge and shock.
5.Disorders with remote control and alternative control methods
Sometimes the Xiaomi TV doesn't turn on because it's broken, but because of a faulty remote.
- 📱 Use the Mi Remote app: download it to your smartphone (available for Android and iOS) and try turning on your TV via your phone.
If the remote is not working and the TV is still not turning on, try to control it through buttons on the case. Most Xiaomi models have physical buttons for:
- On/off (Power)
- Volume control (Volume +/-)
- Selecting a signal source (Source or Input).
If the buttons on the body also do not respond, but the power indicator is on, the problem may be in the control chip or firmware, in which case the reset or flashing (see sections 2 and 3) will help.
6. When to contact the service center
Not all breakdowns can be repaired on your own, but there are situations where repairs to the service are the only way out:
- 💥 Matrix damage: cracks, broken pixels, or stripes on the screen that don’t disappear after flashing.
- ⚡ Failure of the power supply: if the TV does not respond to reset and does not turn on even through direct firmware.
- 🔥 Burnt elements on the board: blackened or bloated capacitors, burned tracks.
- 🎛️ Problems with T-CON board (matrix controller): no image at working sound.
The cost of repair depends on the model and the nature of the breakdown.
- Replacement of the power supply: from 2000 to 5 000 rubles.
- Maternity Board Repair: from 3 000 to 10 000 rubles.
- Replacement of the matrix: from 10 000 rubles (sometimes cheaper to buy a new TV).
If your Xiaomi TV is guaranteed, don’t disassemble it yourself – this will void warranty obligations. Contact the official Xiaomi service center with a check and a warranty card. A list of authorized services can be found on the Mi Service website.
⚠️ Note: if the Xiaomi TV does not turn on after a fall, impact or hit by liquid, self-repair can aggravate the situation.
7 Prevention: How to avoid problems in the future
