Introduction: When Xiaomiโs remote stops listening
You have pressed the switch on the Xiaomi Mi remote TV, But the TV is silent like a fish, or it's reacting over and over and over again, and sometimes it's not doing the right thing. 90% In some cases, the problem can be solved independently. 10-15 minute.
Remote controls (DUs) from Xiaomi TVs are reliable, but they are not immune to failures, and the causes can be found in the remote itself (discharged batteries, mechanical damage) and in the TV (sync failure, IR problems). In this article, we will analyze all possible reasons why the Xiaomi remote may not work, and give step-by-step instructions for their elimination, from basic checks to complex technical manipulations.
We will pay special attention to the Mi models. TV 4/4S/4A, Mi TV 5, Mi TV Q1/Q2 Redmi Smart TV, Because their remotes have specific features (e.g. Bluetooth support in new versions) If your TV is different, some of the tips will still be useful, but some of the nuances may differ.
1. discharged or improperly installed batteries
The most common, but also the most common, cause is the dead batteries, and even if you've changed them recently, check again: sometimes the batteries run out in a few days because of factory failure or high power consumption of the remote (especially if it's lighted).
How to check:
- ๐ Visual inspection: take out the batteries and check for contact oxidation or body bloating, and if the terminals have green plaque, it needs to be cleaned with alcohol carefully.
- ๐ Reset: Remove the batteries, wait 30 seconds, and insert back in polarity, and sometimes the contacts stick and don't provide a reliable connection.
- ๐ Test with another device: insert the batteries into another remote (for example, from the air conditioner) or check them with a multimeter.
If the batteries are fine, but the remote doesn't work anyway, try resetting it.
- Remove the batteries.
- Press the Menu buttons simultaneously + OK (home + Back for new models).
- Without releasing the buttons, insert the batteries back.
- Hold the buttons for another 10 seconds, then let go.
2. Problems with the IR transmitter or Bluetooth module
Xiaomi remotes come in two types:
- ๐ถ Infrared panels use invisible light to transmit a signal, operate up to 8 meters away, but require a line of sight.
- ๐ต Bluetooth remotes โ wireless, do not require direction, but can glitch when interference from other devices.
How to determine the type of your remote:
| Sign. | IR remote | Bluetooth remote |
|---|---|---|
| Television models | Mi TV 4/4S/4A, Redmi TV 70" | Mi TV 5, Mi TV Q1/Q2, Redmi Smart TV X |
| Appearance | A transparent "window" at the top | No visible IR transmitter. |
| Work without direction | No (to aim) | Yes (operates within 10m radius) |
If you have an IR remote:
- ๐ฆ Check the cleanliness of the transmitter: wipe the window with an alcohol napkin. Dust and fat block the signal.
- ๐ฑ Use your smartphone camera: point the remote to the camera and press any button. If the IR transmitter is working, you'll see violet light flickering.
- ๐ก Make sure there are no obstacles between the remote and the TV (glass, mirrors, direct sunlight can block the signal).
If you have a Bluetooth remote:
- ๐ Reconnect the remote: go to Settings โ Bluetooth โ List of devices and delete the remote, then repeat synchronization.
- ๐ถ Check for interference: Disable other Bluetooth devices (earphones, fitness bracelets) that can create conflicts.
- ๐ Reset Bluetooth settings on your TV: Settings โ System system โ Reset โ Resetting network settings.
๐ก
If you have an IR remote, try bringing it as close to the TV as possible. 10-15 If the TV reacts, the problem is the weak signal, maybe you need to change the transmitter.
3. failure of the remote with the TV
Sometimes the Xiaomi TV will forget the tethered remote, especially after updating the firmware or resetting settings, in which case you need to re-synchronize.
Instructions for IR panels:
- Turn on the TV with a button on the body (if any).
- Press and hold the Menu buttons. + OK remote 5-7 seconds until the indicator flashes twice.
- Point the remote to the TV and press OK.
Instructions for Bluetooth remotes:
- Go to Settings โ Devices โ Bluetooth.
- Select "Add Device" and hold down the Home buttons. + Back on the remote for 10 seconds.
- Wait for the remote to appear in the list and confirm the connection.
If the synchronization fails:
- โก Check if the TV is on "For children" (it can block the connection of new devices).
- ๐ Reboot the TV: Turn it off for 1 minute, then turn it on again.
- ๐ Make sure you use a native remote from your Xiaomi model.Remotes from other TVs (even the same brand) may not be suitable.
What if the TV doesnโt respond to the switch?
4. Mechanical damage to the remote
Xiaomi remotes often fall, pour coffee or simply wear out over time.Mechanical damage may not be obvious, but critically affect the work.
Signs of mechanical failure:
- ๐ง Liquid intake: The remote stops working after spilled beverage or high humidity.
- ๐จ Cracks on the case: even a small crack can disrupt the integrity of the board.
- ๐๏ธ Button sticking: If the button is pressed with difficulty or does not return to its original position, this blocks the signal.
How to diagnose:
- Disassemble the remote (carefully tuck the latches with a plastic card).
- Check the fee for oxidation, track breaks or bloated capacitors.
- Check the rubber contacts under the buttons โ they should be clean and resilient.
If damage is found:
- ๐งด Oxidized contacts clean with isopropyl alcohol (at least 90%) and toothpick.
- ๐ง Wash the sticky buttons with soap solution and dry for 24 hours (without batteries!).
- ๐ If the fee is damaged, it is easier to buy a new remote (original costs from 800 to 1500 rubles).
๐ก
If the remote is falling into the water, DO NOT DRY IT WITH THE PHENO or THE BATTERY! High temperatures will damage the board. The optimal way is to put it in rice on the back of a battery. 12-24 hourly.
5. Problems with the IR receiver or Bluetooth TV module
If the remote is functional, but the TV is not responding, the problem may be the signal receiver on the TV itself, which is true for both IR and Bluetooth modules.
How to check the IR receiver:
- ๐ Look at the front of the TV and look for a small transparent or dark window (usually on the right or bottom).
- ๐ธ Point your smartphone camera at it and press the button on the remote. If the receiver is working, you'll see a flicker.
- ๐งฒ Check if there are any sources of infrared interference (for example, halogen lamps or sunlight) near you).
How to check the Bluetooth module:
- ๐ Restart the TV and try connecting another Bluetooth device (e.g. headphones).
- ๐ Check if Bluetooth is enabled in the settings: Settings โ Devices โ Bluetooth.
- ๐ง If the module does not detect the device, it may be necessary to flash or replace the antenna.
If the receiver is not working:
- ๐ ๏ธ For the IR module, sometimes soldering contacts helps (solding skills are required).
- ๐ For Bluetooth, try resetting your network settings: Settings โ System system โ Reset โ Resetting Wi-Fi and Bluetooth.
- ๐ฆ In extreme cases, modules can be replaced independently (the cost of an IR receiver is from 300 rubles, Bluetooth - from 1000 rubles).
