Xiaomi TV doesn’t show an image, but there’s sound – what to do in 2026

You turned on your Xiaomi Mi TV, the sound is working and the screen is black or flashing? This is one of the most common problems in a smart TV brand, and in 80% of cases it can be fixed by yourself without calling the wizard. The reasons for missing the image when the audio is saved fall into two groups: software failures (incorrect settings, firmware errors) and hardware malfunctions (damage to cables, matrix or motherboard).

In this article, we will look at all possible scenarios, from basic checks (cables, signal sources) to complex manipulations (reset to factory settings, flashing), and focus on Mi TV 4A/4S/4X, Mi TV Q1/Q2 and Redmi Smart TV models, because their architecture has specific “weaknesses.” If the diagnosis turns out that the problem is hardware, you will learn how to estimate the cost of repairs and avoid cheating in the service center.

1. Connection verification: cables, ports and signal sources

The first thing to do is to rule out the trivial reasons for physical connections, even if you're sure that "everything is connected correctly," double-check:

• 🔌 HDMI-cables: try replacing the cable with a known working one (for example, from another device). TV 4S 55" where ports HDMI 2.0 is sensitive to cable quality.
• 📺 Signal source: switch the TV to another input (e.g., from a different input). HDMI 1-on HDMI 2 or AV). If the image appears - the problem in the console, receiver or game console.
• ⚡ Power: Turn off the TV for 30 seconds, then turn it back on. This will reset temporary errors in the power supply (relevant for models with a power supply). ATX-block).
• 🔄 Mode Switching: Press the Source (or Input) button on the remote and select another source. Sometimes the TV hangs on a non-existent input.

If you use an Android TV Box or a game console, try connecting it to another TV, which will help localize the problem, for example, the Xiaomi Mi Box S sometimes conflicts with the same brand of TVs due to incompatibility of HDCP protocols.

⚠️ Attention: If the switching of sources screen for a split second "wakes up" (the logo appears Xiaomi or menu), but immediately goes out - this is a sign of malfunctioning backlight matrix.

2. Resetting image and sound settings

When you have a downed brightness, contrast or mode setting, it can make the image invisible, but the sound keeps working, for example, if you manually set the brightness to 0%, the screen will appear to be off.

To return the parameters to the factory:

1. Press the button Settings (cogs) on the remote.
2. Go to Settings → Picture → Additional settings.
3. Select Reset Image Settings (or Reset Picture Settings in English firmware).
4. Confirm the action.

If you can’t see the menu on the screen, try to control the TV blindly:

• 🎮 Use a game controller (for example, from Xiaomi Game Controller), connected over Bluetooth - it duplicates the functions of the remote.
• 📱 Install the Mi Remote app on your smartphone (available for Android and iOS) and control your TV over Wi-Fi.

If the reset didn’t help, move on to the next step – firmware diagnosis.

3. Update or roll back firmware

Software bugs are a common cause of black screens on Xiaomi TVs. For example, there was a bug in the V12.0.4.0 firmware for the Mi TV Q1E that went out of the screen after going to sleep, and the solution was to upgrade to the current version.

How to update the firmware if the screen is not working:

1. Download the latest firmware for your model from the official Xiaomi Support website (select a file with the.zip extension).
2. Unpack the archive and copy the update.zip file to the flash drive (FAT32 format).
3. Connect the flash drive to USB-television-port.
4. On the remote, tap sequentially: Menu → Settings → All Settings → About → System Update → Update via USB.

If the TV doesn’t respond to buttons, try a forced reset:

1. Turn the TV off the socket.


2. Press the Menu button on the remote.




3. turn the TV on, holding the Menu for 10-15 seconds.




4. Release the button - the recovery menu should appear.
