Xiaomi's remote control stopped responding to pressing? Don't rush to buy a new one -- 85 percent of the time, you can fix the problem yourself in 5 to 15 minutes. This guide will work for all Mi devices: Mi TVs, Mi Box S/4K set-top boxes, Mi Smart Projector projectors, air conditioners, and even smart lights with remotes. We'll sort out hardware malfunctions, software failures, and external interference, and we'll give checklists for quick diagnostics.
Many users mistakenly think that if the remote doesn't flash with the LED, it's broken. In fact, the lack of indication is only one symptom, and often it's not caused by a breakdown, but by a discharged battery or an IR lock. In this article, you'll find step-by-step algorithms for each type of device, including rare cases, such as when the remote only works at close range or reacts with a delay.
Before you start the repair, answer one question:
1. Elementary testing: batteries, infrared port and mechanical damage
Start with the obvious, the power source. Even if you've recently changed batteries, they may have been defective or run out of power because of a short circuit in the remote, take a multimeter (or just insert the batteries into another device) and check the voltage: for two finger batteries (AAA), it should be at least 2.8 V.
If the batteries are fine, inspect the IR transmitter (usually located at the top of the remote under a plastic lens).Contamination or damage to this element blocks the signal. Wipe it with a cotton swab dipped in alcohol - often enough to restore operation.
- π Batteries: try replacing them with new ones (even if the old ones "seem to work"). Use Duracell or Energizer alkaline batteries, which last longer.
- π IR port: flash a flashlight into the transmitter -- if you see debris or scratches, clean it. Don't use sharp objects!
- π₯ Mechanical damage: check if the remote body bends. Even a slight deformation can shift the board and disrupt the contacts.
β οΈ Warning: If the remote has fallen into water or been exposed to moisture, do not turn it on immediately.Put it in a silica gel bag (out of a shoe box) for 24 hours, then dry the hair dryer at minimum temperature.
2. IR signal diagnostics: how to check if the remote is sending commands
To make sure that the remote is actually transmitting, use your smartphone camera. Turn on the camera, point the IR remote into the lens, and press any button. If the remote is working, you will see a flashing purple light on the phone screen (the human eye does not perceive it).
The absence of flashing means:
- π Failure of the IR LED (soldling or replacement required).
- π± Damage to tracks on board (often after falling).
- π Underpowered (even if the batteries are new, check the contacts).
If you have a signal, but the device is not responding, the problem is in the receiver (for example, in a TV or a set-top box), try to point the remote from a distance of 1-2 meters at right angles, if it works, then the IR receiver is contaminated or damaged.
π‘
If you don't have a smartphone, use a digital camera or a laptop webcam, and the main thing is that the device has an IR filter (most modern cameras don't have one).
3. Reset remote and device binding: instructions for Mi TV, Mi Box and other gadgets
Sometimes the remote is untied from the device after a firmware update or failure. To re-bound, follow the following steps:
For Mi TVs (all models including Mi TV 4S, Mi TV Q1):
- Turn off the TV for 1 minute, then turn it on.
- Press and hold the Menu + OK buttons on the remote for 10 seconds.
- Bring the remote to the IR receiver of the TV (usually at the bottom right) at a distance of 5-10 cm.
- Wait for the beep or flash of the indicator on the TV.
For the Mi Box S/4K:
1. Turn off the power console for 30 seconds.
2. Turn it on and press + on the remote immediately.
3. Hold for 5 seconds until the reset notification appears.For smart lamps and air conditioners: It usually requires a complete reset of the device (press the button on the case for 10-15 seconds), then re-tether through the Mi Home app.
Make sure batteries are charged | Check the IR transmitter for contamination | Turn the device off the network for 1 minute | Press the button combination to reset | Repeat the binding from close range-->
4. Software failures: firmware update and reset settings
If the remote is working but the device is late or not following commands, the problem may be the firmware. For example, after upgrading the Mi TV to Android TV 11, many users have faced a sticky button.
- π Update: Go to Settings β On TV. β Update the system and install the latest version.
- βοΈ Resetting settings: in the Settings menu β Preferences β Reset select "Reset remote settings".
- π± Reconnect via Mi Home: for smart devices, remove the gadget from the app and add again.
For consoles Mi Box sometimes helps to clean the cache:
- Go to Settings β Applications β All applications.
- Find Remote Control and select Clear Cache.
- Reboot the console.
β οΈ Note: After resetting the remote settings on Mi TV You can fly the binding to the Xiaomi account. Remember the username and password in advance or untie the TV from the account in Settings β Account.
5. External interference: what blocks the remote signal
If the remote is only working at close range or at times, external factors may be to blame:
| source of interference | How to check | Decision |
|---|---|---|
| Bright sunlight | Direct the remote to the device with the lights off | Close the curtains or use the remote in the evening |
| Fluorescent lamps | Turn off all the lamps in the room. | Replace them with LED or halogen |
| Other IR devices | Turn off the air conditioning, music center | Move the remote and device away from each other |
| Metallic objects | Remove all metal boxes, frames | Place the remote and receiver at a distance of 1-2 m without obstacles |
Critical information: Some Mi TV models (e.g., Mi TV 4X 55) have an IR-receiver vulnerability to infrared rays from the sun. If the TV is facing the window, even reflected light can block the remote signal, the solution is to use curtains or redirect the TV.
6. Hardware repair: what to do if the remote is physically broken
If the diagnosis showed that the remote does not transmit a signal, and the batteries and contacts are in order, there are two options:
- Repair of the IR LED. To do this, you need to disassemble the remote, check the circuit with a multimeter and replace the LED if necessary (cost - from 50%) β½).
- Replacement of the board: If the board itself is damaged (for example, after a fall), it is cheaper to buy a new remote (from 800) β½ for Mi TV).
To disassemble the Xiaomi remote, you will need:
- π§ Screwdriver. T5 screwdriver.
- π§² Magnetic propeller substrate.
- π₯ Hair dryer (for softening the glue if the body is glued together).
Step-by-step:
- Carefully tuck the latches of the body (usually they are located on the sides).
- Unscrew the screws and remove the top cover.
- Check the contacts of the batteries for oxidation (clean with a lastic).
- Call the multimeter IR LED (resistance should be ~1.2-1.5 kΞ©).

7. Alternative control methods: if the remote control cannot be repaired
While you are waiting for a new remote or parts, you can control the device in other ways:
- π± Mi Remote app: download it to your smartphone (Android / iOS). Supports all Xiaomi devices.
For smart lamps and air conditioners, temporarily set up control via:
- Geolocation in Mi Home (automatically activated when returning home).
- Voice commands via Alice or Google Assistant.
- Timers in the device settings.
π‘
If you have a Mi TV with Android TV 10+, you can control it from Google Home without a remote, just say, "OK, Google, turn on Mi TV in the kitchen."
8.When to contact the service: signs of a serious breakdown
If you have tried all the methods, but the remote still does not work, it is possible that the problem lies in the hardware malfunction of the device (TV, set-top box, etc.).
- π¨ The remote does not work from any distance, although the signal is there (a problem in the IR receiver of the device).
- π The device does not respond even to alternative control methods (for example, buttons on the body).
- β‘ After connecting to the network, the device emits unusual sounds (clicks, squeaks) or does not turn on.
For Xiaomi devices in Russia, the official service is Mi-service (list of centers: mi.com/ru/service). Average cost of diagnosis β 500 β½, retrieval β 1 500β3 000 β½.
β οΈ Warning: If your device is warranty, don't disassemble it yourself! Opening the case will void warranty obligations. Instead, go to the store with a check and a package.
