You try to turn on the Xiaomi Mi TV from the remote, but the screen is black and the indicator does not respond? The problem is found in models from Mi TV 4A to Mi TV Q2, and there are several reasons - from banal discharge of batteries to a firmware failure. In this article, we will analyze all possible malfunctions and give clear instructions on how to bring the TV back to life without calling the master.
It's important to understand that if the TV doesn't turn on at all (even with a button on the body), that's one situation. If it starts manually but ignores the remote, it's another. We'll look at both scenarios, and we'll also talk about how to tell the difference between hardware failure and software failure, and we'll start with the simplest one: checking the remote control and the power sources.
1. Checking the remote control: batteries, infrared port and mechanical damage
In 60 percent of cases, the problem is the remote control.
- π Replace batteries, even if they're "almost alive." Use an alkaline (Duracell, Energizer) or lithium battery. Cheap salt cells quickly put voltage down.
- πΈ Check the IR port with your smartphone: open the camera, point the remote to the lens and press any button. If you see a flicker on the phone screen, the port is running.
- π§Ή Clean the contacts inside the battery bay with a cotton swab dipped in alcohol.
- π₯ Make sure the integrity of the case: cracks or dents can damage the remote board.
If the remote has fallen into the water or been severely impacted, there is a high probability of damage to the quartz resonator or chip, in which case it is easier to buy a new remote (the original for Xiaomi is worth it). ~1500β½, universal - from 500β½).
β οΈ Note: Do not use remotes from other devices (such as air conditioning) for the test β they work on other frequencies and are not compatible with Mi. TV.
If after all the manipulations, the remote doesn't work, try turning on the TV with a button on the case (usually located under the logo or on the side). If the TV is turned on, the problem is exactly in the remote. If not, then proceed to the next step.
2. Resetting remote settings and reconnecting to the TV
Sometimes the remote is untied from the TV after a firmware update or failure, to reset the connection and reconnect it:
- Remove the batteries from the remote for 30 seconds.
- Insert the batteries back and hold the Menu + OK buttons simultaneously for 10 seconds.
- Point the remote to the TV (no more than 1 meter away) and press Power.
- If the indicator on the remote flashes 2 times - the connection is restored.
For models of Mi TV Q1/Q2 with Bluetooth remotes (for example, Xiaomi Mi TV Remote Pro) may need to re-synchronize:
- Go to Settings β Devices β Remote and accessories.
- Select "Add remote" and follow the instructions on the screen.
βοΈ Checklist before resetting remote
If reconnecting doesn't work, check if the remote is blocked by an infrared filter on the TV (the thin film in front of the receiver) that may be contaminated or damaged -- gently wipe it with a dry wipe.
3. TV power problems: power supply, cables and socket
If the TV doesn't respond to the remote or the power button, it could be the power supply or the network settings that are at fault.
- π Socket and cable: connect to another socket (preferably with grounding). Use the original power cable from Xiaomi - Chinese "nouneim" analogues may not provide the desired voltage.
- β‘ Power indicator: the front of the TV should be a red or orange LED. If it does not glow, the problem is the power supply.
- π Hard reset: disconnect the TV from the network for 5 minutes, then hold the switch on 15-20 seconds.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The indicator is not on. | Failed power supply or cable | Check the cable, tester to measure the voltage on the block |
| The indicator flashes red. | Standby mode or firmware failure | Hard reset or software update |
| The indicator is green, but the TV is not turned on. | Maternity board malfunction | Contact the service center |
| The TV is turned on, but immediately turned off. | Overheating or malfunction of the illumination inverter | Check the ventilation, clean the dust |
For the Mi TV P1 and newer Quick Start+ models, the TV may appear off, but is actually in deep sleep mode to get it out of this state:
- Turn off the function in settings: Settings β Power β Quick start.
- Completely turn off through the menu.
π‘
If the TV turns on after only a few attempts, check the capacitors on the power supply - their bloating or leakage often causes unstable operation.
4. Resetting the TV to factory settings
If the TV is switched on with a button on the body, but does not respond to the remote, the software may crash.
- System freezes after the update.
- Application conflict (for example, after installing a third-party launcher).
- Loss of communication with the remote due to failure Bluetooth/IR module.
How to perform the reset:
- On the TV turned on, go to Settings β Device β Reset and Recovery.
- Select "Reset all settings" (required) PIN-default code: 0000 or 1234).
- Confirm the action and wait for the reboot (it will take 3-5 minutes).
If the TV doesnβt turn on but responds to the power button, try a hardware reset:
- Shut the TV off the grid.
- Press the Volume button on the body and, holding it, connect the power.
- Hold the button for 10-15 seconds until the recovery menu appears.
- Select Wipe Data/Factory Reset using volume buttons and confirm with the power button.
β οΈ Note: After the reset, all installed apps, accounts and personal settings will be deleted. Write down your Mi Account login details in advance if you used sync.
5. Manual firmware update (if the TV is turned on but the remote is not working)
Failures after automatic updates are a common cause of loss of communication with the remote. If the TV turns on with a button on the case, but the remote does not respond, try to roll back or update the firmware manually:
- π₯ Download the latest firmware for your model from the official Xiaomi Support website. TV 4S 55" The file will be called miui_tv_mitv4s_55_vXXXXX.zip.
- πΎ Copy the file onto a flash drive (FAT32, 32 GB or less in the root directory (not in the folder!).
- π Update TV through the menu: Settings β On TV. β Updating the system β Local Update.
If the TV does not turn on at all, but reacts to the connection to the network (the indicator lights up), you can try to update the firmware through the recovery mode:
- Download the firmware and rename the file to update.zip.
- Place it on a formatted flash drive.
- Put the flash drive in the TV turned off.
- Press the Menu button on the case and connect the power.
- Hold the button for 10-15 seconds until the update starts (the progress bar will appear on the screen).
What to do if the firmware is βhungβ at 0%?
For Mi TV Q1/Q2 models with Google TV, the update may be blocked due to a conflict of services.
- Go to Settings β Applications β Google Play Store.
- Clear the cache and data.
- Repeat the update attempt.
6. Hardware malfunctions: when without service can not do
If all software methods have been tried, but the TV still doesnβt turn on from the remote, the problem may be:
- π οΈ IR receiver malfunctions (often after a fall or impact).
- π Damage to the motherboard (blown capacitors, burned tracks).
- π Failure of the power supply (typical for TVs over 3 years old).
- π‘ Bluetooth module failure (relevant for Xiaomi Mi remotes) TV Remote Pro).
It is difficult to diagnose hardware problems on your own, but you can check several points:
- Check the board for bloated capacitors (they look like barrels with a convex top).
- Check the fuses on the power supply multimeter (should be resistance ~0 ohms).
- Make sure the plumes connecting the motherboard to the control buttons are not moved away.
If you don't have experience in electronics repair, you should contact a service center.
- Replacement of IR receiver: 800β1500β½.
- Repair of the power supply: 1500β3000β½.
- Replacement of motherboard: 5000β12000β½ (model-wise).
β οΈ Attention: Dust and moisture are the main enemies of Xiaomi TVs. If the TV was in a damp room or did not clean for a long time, the chances of corrosion of contacts are high, in which case, even after repair, the problem can recur.
π‘
If the TV is warranty (up to 12 months from the date of purchase), do not disassemble it yourself - this will void the warranty obligations.
