How to return the image on the TV Xiaomi: 7 working ways

You turned on a Xiaomi TV, but the screen is black, flashes or displays a message "No signal"? Image problem is one of the most common malfunctions in a smart TV, but in 90% of cases it can be solved independently without going to the service center. The reasons for the absence of a picture range from banal (disabled HDMI cable) to technical (firmware failure or hardware defect of the matrix).

In this article, we will look at all the possible ways to recover images on Xiaomi Mi TV, Redmi Smart TV and Mi Box consoles, from basic connection checks to hidden service functions. We will focus on diagnosing the problem: learn how to distinguish a software failure from a hardware failure so that we don’t waste time on useless manipulations. If your TV turns on but the screen remains black when there is sound, this is one scenario; if the power indicator does not burn at all, another.

1. Check of basic connections: cables, sockets, signal sources

📺 Make sure the power indicator on the body is on or flashing

🔄 Reconnect. HDMI/USB-cables (remove and insert back)

🔊 Check if there is sound without an image (if so, a problem in the matrix or settings)

📡 Reboot your router if you use a Smart TV-function-->

Pay special attention HDMI-On Xiaomi TVs, they are often labeled as HDMI 1 (ARC), HDMI 2, etc. Try connecting the signal source (set-top box, computer) to another port - sometimes one of the connectors fails. If you use the Mi Box, check that the Micro-HDMI cable (in older models) or HDMI 2.0 (in new) sits tightly in the nest.

• 🔄 Soft reset: Disables power without data loss, suitable if the TV is getting stuck on a black screen but reacts to the remote.
• ⚡ Hard reset: Complete power outage for 1-2 minutes, helps with severe firmware failures.

For a soft reboot:

1. Press and hold the power button on the remote for 10-15 seconds.
2. If the remote is not working, use a physical button on the TV body (usually located on the side or bottom).
3. Wait until the power indicator goes out and lights up again.

For hard reset:

1. Turn off the TV from the outlet.
2. Press and hold the power button on the case for 30 seconds (discharge the residual charge of the capacitors).
3. Connect the power back and turn on the TV in 1-2 minutes.

Once a week.

Only when problems arise
