Xiaomi remote from the TV does not work: all the reasons and ways to fix

You have pressed the switch on the Xiaomi Mi remote TV, But the TV doesn't react? Or do the buttons work over and over and the cursor on the menu twitches on its own? TV 4A/4S/4X/5/5X/Q1/Q2/P1) They are often found, but in 90% cases can be eliminated independently without contacting the service center.

In this article, we'll look at all the possible reasons why the remote is not working, from the trivial (discharged batteries) to the rare (infrared transmitter damage), how to check the remote for performance, reset its settings, reprogram it to another TV, and even use the smartphone as a replacement, and if the problem is in the TV itself, give instructions to restore its sensitivity to the signal.

For convenience, we have compiled a table of compatibility codes for universal remotes, a diagnostic checklist and answers to frequent questions. Don’t rush to buy a new remote – in 8 out of 10 cases, the old one can still be “resuscitated”!

1. Elementary testing: batteries, obstacles and distance

Start with the obvious: batteries. Even if they're "nearly new," their voltage could drop below critical levels. Xiaomi remotes are particularly sensitive to this: at voltages below 2.8 V, they stop sending signals, although the LED can still blink.

How to check:

• 🔋 Replace the batteries with new ones (preferably Duracell or Energizer alkaline batteries). Even if the old ones "seem to work" - install them.
• 📏 Reduce the distance to the TV to 1-2 meters. the IR signal weakens at a distance of more than 5-7 meters.
• 🚫 Remove obstacles: Glass countertops, mirrors, or direct sunlight can block the signal.
• 🔦 Illuminate your smartphone with an IR transmitter (usually located at the top) and you press the buttons and you see purple light (through the camera) and if you don't have it, the remote is not working.

If the remote is running after replacing the batteries, but it is again "glutching" after a few days, the problem may be oxidized contacts inside the compartment.

2. Resetting the remote and reconnecting to the TV

If the Xiaomi remote flashes but the TV doesn’t respond, there may have been a synchronization failure, which is true for Bluetooth remotes (such as Mi Remote or Mi Game Controller) that require pairing. IR remotes (with an infrared port) usually don’t need to be connected, but can also “forget” settings.

Resetting instructions:

Remove the remote from the list of devices in the TV settings (Settings → Bluetooth and devices)

Remove the batteries from the remote for 10 seconds

Press and hold the OK + Back buttons simultaneously for 5 seconds (for IR remotes)

For Bluetooth remotes: Enable mating mode (press Home + Volume Up for 3 seconds)

Bring the remote to the TV at a distance of 10-20 cm and wait for automatic connection-->

If the remote is still not working, try forced synchronization:

1. Open on the TV Settings → Input devices → Remote DU.
2. Select Add Remote and follow the instructions on the screen.
3. For IR remotes, code entry may be required (see table below).

💡

If the remote works after reset, but the buttons are assigned incorrectly (for example, Volume Up reduces sound), try reprogramming it through the Settings menu → Remote → Customization of buttons

3. Problems with the IR transmitter or Bluetooth module

If the remote doesn't blink when you press the buttons (even with new batteries), the IR transmitter or Bluetooth module is likely to fail, a typical problem for remotes that often drop or pour liquid.

How to diagnose:

• 🔍 Visual inspection: check if there are cracks in the case or traces of corrosion near the LED.
• 📱 Testing via smartphone: use the app IR Universal Remote (Android) or Mi Remote (iOS/Android) certify.
• 🔄 Connect another remote: if the second remote works, the problem is in the first.

If the transmitter is damaged, there are two options:

1. Repair: Take apart the remote (carefully chopping the latches) and check the soldered IR LED contacts, sometimes soldering them helps.
2. Replacement: original remotes for Xiaomi Mi TV They're 800-1500. ₽ (Universal IR panels (e.g. One For All) will be cheaper (300-600) ₽).

4. TV settings: why it doesn't respond to the remote

Sometimes the problem is not the remote, but the settings of the TV, for example, after updating the firmware, the IR receiver may turn off or the control mode may be lost.

What to check:

• 📺 Mode "Demo" or "Hotel": in some firmware (Mi) TV 4X, Mi TV 5) these modes block the external remotes. Turn them off in Settings → System system → Mode of work.
• 🔄 Resetting IR port settings: go to Settings → Input devices → DU remote → Reset.
• 🔌 Power IR receiver: if the TV does not respond to any remote, it may be out of order the IR module (requires repair).

On Xiaomi TVs based on Android TV 9+ (such as Mi TV Q1 or Mi TV P1), you may need to re-pair the Bluetooth remote after resetting to factory settings – even if it previously worked.

If your TV doesn't respond to the universal remote, try the codes from the table one by one.

1. Press and hold the SET (or CODE SEARCH) on the universal remote.
2. Enter the 3-4-digit code from the table.
3. Point the remote to the TV and press POWER. If the TV is off, the code fits.

5. Alternative ways to control the TV

While you’re waiting for a new remote or repairing an old one, Xiaomi TV can be controlled in other ways:

• 📱 Mi Remote: Bluetooth or Wi-Fi (requires connection to the same network as TV) download from Google Play or App Store.
• 🖱️ Mouse or keyboard: connect to USB or Bluetooth via Settings → Input devices.
• 🎮 Gamepad: Xiaomi Mi Game Controller or any Android compatible TV.
• 🔧 Buttons on the case: on the back of the TV there are physical buttons Power, Volume and Input.

To manage through Mi Remote:

1. Connect your TV and smartphone to the same Wi-Fi network.
2. Open the app and select Add Device → TV → Xiaomi.
3. Follow the instructions on the screen (you may need to enter) PIN-TV-code).

💡

The Mi Remote app works even if the TV's IR port is broken - it uses Wi-Fi or Bluetooth to transmit commands.

6.When you can not do without repair: signs of serious malfunctions

If none of these things worked, there may be a problem with the hardware of the TV or the remote, and here are some signs you should check out the service:

• ⚡ The TV does not respond to any remote control (including universal and application).
• 🔥 IR receiver on TV is physically damaged (cracks, burn marks).
• 🔄 The remote works, but the TV turns on / off spontaneously - this may indicate a malfunction of the motherboard.
• 💧 On the board of the remote control there are traces of liquid or oxidation.

Cost of repair:

• Replacement of IR receiver on TV: 1000-2500 ₽ (model-wise).
• Remote board repairs: 500–1500 ₽ (if recovery is possible).
• Diagnosis of the motherboard TV: from 1500 ₽.

⚠️ Warning: If the TV is warranty, don't disassemble it yourself! opening the case will void warranty obligations. Contact the Xiaomi Authorized Service Center with a check and warranty card.

For the 2020-2026 Xiaomi Mi TV models (e.g., the Q2 75" or P1 55"), the IR receiver usually takes 1-2 days to replace. For older models (e.g., the Mi TV 3), spare parts may be missing, in which case it is easier to buy a new remote.

7. Prevention: how to prolong the life of the Xiaomi remote

To avoid problems in the future, follow simple rules:

• 🔋 Use high-quality batteries (not cheap salt batteries) and change them every 6 to 12 months, even if the remote is running.
• 🚫 Do not drop the remote – blows often damage soldered contacts of the IR LED.
• 💦 Avoid moisture: Do not leave the remote in the bathroom or kitchen near the sink.
• 🧹 Clean the contacts of the battery compartment every six months (alcohol tampon).
• 📱 Update the firmware of the TV – in new versions often fix bugs with control.

If you have children or pets, consider buying a protective cover for the remote (such as silicone) that will keep it from mechanical damage and fluid intrusion.

💡

Keep your spare remote control (or at least your batteries) in an accessible place. If the main remote fails, you won't have to search for a replacement.
