Why Xiaomi Mi TV remote stopped working: the main reasons
If your remote control (DU) from the Xiaomi Mi TV suddenly stopped responding to the presses, do not rush to panic. 80% of the time the problem is solved in 5-10 minutes without contacting the service center.
Xiaomi TVs (Mi series) TV 4/4A/4S/5/5X/Q1/Q2/P1/E) They use infrared (IR) or Bluetooth remotes. The type of connection depends on the malfunction algorithm, for example, IR remotes are more likely to suffer from mechanical damage and contamination, and Bluetooth models are more likely to suffer from software failures. In this article, we will discuss both cases, as well as consider rare causes that are not written about in the standard instructions.
Before you start the repair, answer two questions:
- Does the TV respond to any remote buttons (including the power button)?
- Does the control work from another remote (for example, from the console or universal)?
The answers will help narrow down the range of possible problems.
1. Checking of elementary causes: batteries, obstacles, distance
Start with the obvious batteries. Even if they were recently replaced, check:
- ๐ Charge: insert the batteries into another remote or tester, and the voltage must be at least 1.2V on each cell.
- ๐ Polarity: Turn over batteries โ sometimes contacts oxidize on one side.
- ๐งน Contacts: Drink the spring contacts in the bay and on batteries.
If the batteries are in good condition, make sure that:
- ๐บ There are no obstacles between the remote and the IR receiver of the TV (furniture, glass, other devices).
- ๐ Distance does not exceed 8 meters for IR remotes and 10 meters for Bluetooth.
- โ๏ธ Lighting: bright sunlight or fluorescent lights can jam the IR signal. Try operating the TV in the dark.
Important! Xiaomi Mi TV Q1/Q2 IR receiver is hidden behind a black film at the bottom of the frame. If you look at the TV, it is to the right of the logo. Point the remote control there, not to the center of the screen.

2. IR remote diagnostics: signal verification and cleaning
If the remote is infrared (the case does not have a Bluetooth inscription), its work can be checked using a smartphone:
- Turn on the camera on your phone and point the remote to it.
- Press any button โ if the remote is working, a flashing purple light will be visible in the lens.
So the problem is the remote is either the board is faulty or the IR emitter is contaminated.
To clean the remote:
- Carefully disassemble the body (usually it is kept on latches or one screw under the batteries).
- Wipe the IR emitter (a small transparent or black round element) with a cotton swab soaked in alcohol.
- Check the contacts of the buttons โ there should be no grease or dirt on the rubber substrate.
A unique nuance for Xiaomi: in the remotes of the Mi TV series 4A and 5X, the contact path often departs from the power button. If the TV does not turn on from the remote, but reacts to other buttons, this is the problem.

3. Reset and reconnect Bluetooth remote
Bluetooth remotes (such as those from the Mi TV Q1E or Mi TV P1) require pairing with the TV. If the remote suddenly stops working, try:
- Turn off the TV for 30 seconds, then turn it on again.
- Press and hold the Menu + OK buttons simultaneously for 5 seconds โ this will reset the connection.
- Hold the remote to the TV at a distance of 10 to 20 cm and press any button. Automatic pairing should begin.
If the reset didn't help, try forced reconnection:
- Go to Settings โ Devices โ Bluetooth.
- Find the Mi Remote Controller and select Forget the Device.
- Turn off the remote (press the Power + Menu for 3 seconds), then turn it on again and bring it to the TV.
Attention! After resetting the Bluetooth remote, you may need to re-set the voice control (if it has been activated).
๐ก
If the TV does not respond to the Bluetooth remote, but works with IR devices (for example, from the console), the problem is precisely in pairing, not in the hardware of the TV.
4. Software failures: reboot and firmware update
Sometimes the remote will stop working because of a system freeze or a firmware conflict.
- ๐ Soft reboot: Press the power button on the TV (not the remote!) for 10-15 seconds until it turns off and turns on again.
- ๐ฅ Update: Go to Settings โ On TV. โ Update the system. If you have a new version, install it.
- โ๏ธ Resetting settings (last resort): Settings โ Preferences โ Resetting and remediation โ Resetting all settings.
Once reset, the TV will go back to factory settings, and the remote should work, but you'll have to reconfigure your Wi-Fi, accounts and apps.
Important for Mi TV on Android TV 11+: After upgrading to new firmware versions (for example, with MIUI TV 3.0 on 4.0), you may need to re-pair the Bluetooth remote.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The remote does not work, but the TV is turned on from a button on the body. | Failure Bluetooth/IK-module | Reboot TV or reset remote |
| The TV doesnโt respond to anything, not even the power button. | System freeze or hardware failure | Disconnect from the network for 1 minute, then turn on |
| The remote works only from close range. | Weak signal of batteries or contamination of the IR emitter | Replace batteries, clean the remote. |
| Individual buttons do not work (for example, volume control) | Wear of contact tracks or oxidation | Disassemble the remote and clean the contacts |
5. Hardware malfunctions: when without repairs can not do
If all previous methods failed, the problem may be in the hardware:
- ๐ก IR malfunctioning./Bluetooth-TV module (often after a fall or impact).
- ๐ Damaged plume connecting the motherboard with the control module.
- ๐ฅ The remote microcontroller failed (for example, after fluid infestation).
Diagnosing hardware problems at home is difficult, but there are indirect signs:
- The TV does not respond to any remote control (including universal).
- On the TV case, you can see bloated capacitors or traces of oxidation.
- The remote worked after the fall, but after a while stopped responding again.
In such cases, contact the service center.
- Replacement of the IR module: 1,500โ2,500 โฝ.
- Repair of the plume: 2,000โ3,500 โฝ.
- Replacement of motherboard: 5,000โ12,000 โฝ (model).

If the TV is warranty, don't disassemble it yourself! opening the case will void Xiaomi's warranty obligations.
6. Alternative ways to control the TV
While the remote is in repair, you can control the Xiaomi Mi TV in other ways:
- ๐ฑ Mi Remote (available for Android and iOS) connects via Wi-Fi or Bluetooth.
- ๐ฎ Gaming controller (e.g. Xiaomi Game Controller or DualShock) via Bluetooth.
- ๐ฑ๏ธ Mouse and keyboard by mouse USB Bluetooth (suitable for navigation on the menu).
- ๐บ Buttons on the TV body (usually located on the side or back).
To connect Mi Remote:
- Download the app from Google Play or the App Store.
- Make sure your phone and TV are connected to the same Wi-Fi network.
- In the app, select Add Device โ Television โ Xiaomi.
- Follow the instructions on the screen (you may need to enter code from the TV).
Attention! When you control the Mi Remote application, you can have a delay of 0.5-1 second, which is normal and involves processing the signal over Wi-Fi.
7. Prevention: how to extend the life of the Xiaomi Mi TV remote
To avoid problems with the remote in the future, follow simple rules:
- ๐ Change the batteries every 6 to 12 months, even if the remote is working.
- ๐งผ Clean the dust and fat remote every 3 months. Use alcohol wipes or compressed air.
- ๐ซ Don't drop the remote or expose it to moisture. Even a small impact can displace the IR emitter.
- ๐ฑ Update the TV firmware. Newer versions often fix Bluetooth bugs.
If you have children or pets, consider buying a silicone remote case. It will protect against scratches, fluids and falls. Xiaomi Mi TV fits cases from Mi Remote Case or versatile models with AliExpress.

Keep the remote in a dry place, away from direct sunlight. The plastic of the case turns yellow and becomes brittle over time.
