Grey screen on Xiaomi TV: 7 ways to remove and return to work

The gray screen on Xiaomi TVs is one of the most common problems faced by users of the brand’s smart TVs: the screen can hang on a gray background with the Mi TV logo, flashing animations or no signs of life at all, except for backlighting. 80% of the time it is due to software failures, not hardware breakdowns. But how to distinguish one from the other and what to do to bring the TV back to life?

In this article, we will look at all the possible causes of gray screens, from the common glitch after an update to serious firmware errors, how to perform soft and hard resets, restore the system via USB or ADB, and when to contact the service center. We will also focus on the nuances for the Mi TV 4S, Mi TV Q1/Q2 and Redmi Smart TV models, where the algorithm of actions may differ.

Important: If the TV reacts to the remote (for example, the backlight changes when you press buttons), the problem is almost certainly software. If the screen remains gray even after 10+ minutes off the network, it can be a hardware failure of the power controller or motherboard, and repair is necessary.

Why the gray screen appears on Xiaomi TV: 5 main reasons

The gray screen is not a diagnosis, it's a symptom, and to treat it properly, you need to understand what triggered it.

• 🔄 Failed firmware update. The TV started updating over Wi-Fi, but the process was interrupted (e.g., the lights were turned off or the router rebooted), resulting in the system only booting up to the initialization stage, but cannot complete the launch.
• ⚡ Failure after a power surge. Even if you use a network filter, sudden voltage drops can damage system files. The models most commonly affected are those with weak power protection (Mi TV 4A, Mi TV 4C).
• 📱 Connected device conflict: Sometimes a gray screen appears when you connect an external hard drive, console, or sound bar to HDMI-CEC, and the system freezes when you recognize the device.
• 🧹 Cache or memory overflow: If you haven’t cleaned your TV for a long time (especially after installing dozens of apps), the system can suffocate when you boot.
• 🛠️ Hardware malfunctions. Less commonly, physical failures are to blame: a matrix plume pin collapse, a RAM failure or an eMMC chip.

Typically, software failures are accompanied by a reaction to the remote (for example, when you press the volume buttons, the screen light changes), and hardware failures are accompanied by a complete “freeze” without any signs of life. If the Xiaomi TV turns on, but the screen remains gray for longer than 5 minutes, this is a reason to reset.

Method 1: Soft reset (reboot) of the TV

Start with the simplest one, forced reboot, which works 60 percent of the time if a system glitch causes a system glitch. Here's how to do it right:

1. Turn off the TV by pulling the power cord from the socket (don’t use the button on the remote!).
2. Wait at least 2 minutes – this time is enough for the capacitors to discharge and the cache to clear.
3. Connect the power back and turn on the TV button on the case (not remote!).
4. If the screen stays gray, wait 5-7 minutes – sometimes the system boots slowly after a crash.

If the soft reset didn’t help, try the button combination for forced reboot (works on most Xiaomi models):

1. Press and hold the Power button on the remote for 10 seconds.


2. Release the button and immediately press the combination:


   Menu + Up (↑) + OK (hold 5 seconds).


3.The TV should reboot with the Mi TV logo.

💡

If you have a Mi TV Q1/Q2 or Redmi Smart TV X, use Home instead of the Menu button.

Method 2: Hard Reset via service menu

If the soft reboot fails, the next step is to completely reset your settings, which will delete all installed apps, accounts and personal data, but return the TV to factory status. On Xiaomi models, there are two ways to make Hard Reset:

• 📺 Service menu (if the TV responds to the remote).
• 🔧 Through buttons on the body (if the screen is unresponsive).

Instructions for resetting via menu:

1. Turn on the TV and wait for the gray screen to appear.
2. On the remote, press sequentially: Settings → Support → Reset to factory settings.
3. Enter. PIN-code (default 0000 or 1234).
4. Confirm the reset and wait for the reboot (may take up to 10 minutes).

Instructions for resetting buttons (if the remote does not work):

1. Turn off the TV.
2. Press and hold the − Volume button on the TV body.
3. Without releasing the button, connect the power back.
4. Hold Volume − for another 10-15 seconds until the recovery menu appears.
5. Select Wipe Data/Factory Reset (use volume buttons for navigation, OK for confirmation).

Take a picture of the current settings of the TV (brightness, sound, networks)

Write down logins/passwords from accounts (Mi Account, Netflix, YouTube)

Disable external devices (configures, hard drives, soundbars)

Prepare a remote with working batteries

⚠️ Warning: Some models (Mi TV 5 Pro, Mi TV Q2) may require re-assignment to your Mi Account after reset. If you don't remember the login details, restore them in advance at account.xiaomi.com.

Method 3: Firmware recovery via USB

If the reset didn't work, and the TV still shows the gray screen, the firmware is likely damaged, and if you do that, manual flashing through the USB- drive will help, and this method works even if the system doesn't boot.

What you need:

• 🖥️ Flash drive format FAT32 (up to 16 GB).
• 📁 Official firmware for your model (you can download it on mi.tv/update).
• 🔌 USB-Hub (if TV ports are not working)

Step-by-step:

1. Download the firmware for your model (for example, for Mi TV 4S 55" is a file of the form msd7a_user_XXXX.zip".
2. Unpack the archive and copy the update.zip file to the root of the flash drive (not to the folder!).
3. Insert the USB 2.0 port on your TV (usually marked as Service).
4. Turn the TV on and simultaneously press: Menu + Up (↑) + OK (hold 10 seconds).
5. From the recovery menu, select Apply update from USB → specify update.zip.
6. Wait for the process to be completed (about 15-20 minutes) and the TV will restart automatically.

⚠️ Warning: Never use firmware from third-party sources (forums, torrents).This can result in a complete lockdown of the TV due to incompatibility or viruses.

Method 4: Recovery through ADB (for advanced users)

If you have experience with ADB (Android Debug Bridge), you can try to restore the TV through the command line.

• 🔌 The TV is turned on but hangs on a gray screen.
• 🖥️ You have a PC with drivers installed ADB.
• 📡 Wi-Fi or Ethernet on TV is active (you can connect over the network).

Instructions:

1. Download and install Google’s Platform Tools.
2. Connect your TV and PC to the same Wi-Fi network.
3. Open the command line (cmd) and enter: adb connect [IP- your TV address]:5555 (You can find out IP on the router or through the Mi Home app.)
4. Run the command to reboot to Recover: Adb shell reboot recovery
5. From the recovery menu, select Wipe cache partition, then Reboot system now.

If the TV doesn't respond to ADB, try connecting via USB-OTG (a special cable is required), but this method is risky - if the wrong commands are given, you can damage the system even more.

Method 5: Checking for hardware faults

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

• 🔌 The TV does not respond to any button (including the power button on the case).
• 💡 Screenlighting is not turned on at all (black screen instead of gray).
• 🔊 There is sound but no image (or vice versa).
• 🔥 The smell of burning or crackling from the body appears.

What to check first:

1. Power supply. Check the capacitors for bloating. If they're deformed, they need to be replaced.
2. Open the back cover and check if the plume is moving away from the motherboard.
3. RAM: On Xiaomi models, the DDR chip often fails (especially after overheating).
4. Flash memory (eMMC) If the memory chip is damaged, the TV will not be able to boot the system.

For the diagnosis of hardware problems, it is better to contact the service center, especially if the TV is warranty. Self-repair can lead to the loss of warranty or aggravate the breakdown.

💡

If the Xiaomi TV is under 2 years old, repairs are guaranteed free of charge, the main thing is not to open the case yourself and keep the check / warranty card.

Method 6: Contact Xiaomi Service Center

If all attempts to bring the TV back to life have failed, the last option is the official service.

• 📄 Prepare documents: check, warranty card, passport.
• 📦 Pack the TV in the original box (or similar in size).
• 📝 Write down the serial number (on the sticker at the back of the TV).
• 🔄 Reset to factory settings (if the TV is responsive at all).

Cost of repair in the service (example prices):

Official service centers Xiaomi in Russia can be found on the website mi.com/ru/service. Before visiting, check by phone whether they are engaged in repair of TVs (some centers specialize only in smartphones).

Preventing the grey screen in the future

To minimize the risk of a gray screen reappearing, follow these guidelines:

• ⚡ Use a network filter or uninterruptible power supply (UPS). Abrupt power surges are a common cause of failure.
• 🔄 Don't interrupt the firmware update. If you start an update, don't turn off the TV or restart the router.
• 🧹 Every 2-3 months, clean the cache and debris through the Settings menu → Storage → Cleanup.
• 📥 Install apps only from an official store (Google Play or Mi App Store). Third-party APK may contain viruses.
• 🔌 Don't connect faulty external devices (hard drives, set-top boxes) to your TV, which can cause system conflict.

If your Xiaomi TV is often “glutty”, consider turning off automatic updates. To do this, go to Settings → About TV → System Update and deactivate the Auto Update option. So you can control the process and avoid crashes due to “raw” firmware.

💡

Check for updates manually regularly (every 1-2 months) to avoid any critical bugs that Xiaomi fixes in new software versions.
