The first thought is that the smartphone broke. But don't panic: 60 percent of the time, the problem is solved without repair, and the causes range from a trivial battery discharge to serious hardware failures.
Black screen on Redmi Note 12, POCO X5 Or Mi 13 can come after a crash, a system update, or even for no apparent reason, and the key is to properly diagnose the source of the malfunction, for example, if the phone vibrates when you call, but the screen is dead, that's one scenario. If the device doesn't show any signs of life, another one, and in this article, we'll look at all the possible causes and give you clear instructions on what to do in each case.

1.Diagnostics: Why Xiaomi's screen isn't turning on
The first step is to determine if your smartphone is alive, and then you can do some simple tests.
πΉ Response test:
- π Calling from another phone β if you hear a call sound or vibration, the problem is exactly in the screen or backlight.
- π Connect to charge - will the charging indicator (red/green light bulb) appear? on new models (Redmi Note 13 Pro)+) The indicator may not be available.
- π§ Connect headphones β if you press the volume buttons you hear system sounds, the phone works.
πΉ Visual examination:

β οΈ Warning: If your phone falls into water or is in a wet environment, donβt plug it into charging, it may cause a short circuit. First, dry the device in rice or silica gel for at least 24 hours.
πΉ Test for hardware failure:
1. Press the power button + volume up for 10-15 seconds.
2 If the phone vibrates and reboots, the problem is software.
3. If there is no reaction, the power controller or battery may fail.| Symptoms. | Probable cause | Can I correct myself? |
|---|---|---|
| The screen is black, but the phone vibrates / sounds are there | Graphics driver failure, damage to display plume | Yeah (reset, reflash) |
| No response to buttons, no charge | Battery discharged, power controller failure | Partially (try "lighting") |
| The screen flashes or flickers | Problems with illumination, damage to the matrix | No (repair needed) |
| The phone is warming up, but it won't turn on. | Short circuit, firmware failure. | No (risk of making the breakdown worse) |
2. Software glitches: how to bring the screen back to life without repair

- π§ Symptoms: The screen flickers, stripes appear, or the image is there, but there is no backlight.
- π° Cost of repair: from 1,500 to 4,000 β½ (model).
πΉ Matrix failure:
- π₯ Occurs when impacted, overheated or moisture hits.
- π Signs: The screen is completely black, but the phone is working (sounds, vibrations).
- π οΈ Solution: Replacement of the matrix only (3,000 to 10,000) β½).
πΉ Failure of the power controller:
- β‘ The phone does not respond to charging, does not turn on, sometimes warms up.
- π Reason: voltage surge, battery wear, factory marriage.
- π§ Diagnostics: Connect to charging - if the indicator doesn't burn, the problem is in the controller.
π‘
If the phone falls into water, don't dry it with a hair dryer! Hot air can damage the chips. Better use silica gel (boxes of shoes) or leave it in rice on the chips. 24-48 hours.
| Breakdown | Average cost of repairs (β½) | Duration of repairs |
|---|---|---|

| Battery replacement | 1 000 β 2 500 | 30-60 minutes. |
β οΈ Warning: If the phone warms up when you connect to a charger, but it doesn't turn on, it's a sign of short circuit. Don't try to repair yourself.
4. discharged battery: how to light up Xiaomi
One of the most common causes of black screens is that the battery is too low, so if the phone has been lying on for a long time without charging, the controller can block the power supply.
πΉ Method 1: Charging through another source
- π Connect your phone to a charger from your laptop (USB 3.0) or power bank.
- β³ Leave on the charge at least for 30-60 Minutes β sometimes the indicator does not light up immediately.

πΉ Method 2: Lighting from another phone
1. Take a working smartphone and an OTG cable.
2. connect your Xiaomi to another phone via OTG.
3. Hold for 5-10 minutes β sometimes it is enough to wake up the battery.
4. Then connect to the normal charge.πΉ Method 3: Direct battery charging (for advanced)
If the phone does not respond to charging, you can try to apply the voltage directly to the battery:
- β‘ You'll need a lab power supply (3.7-4.2V) or charger for Li-ion batteries.
- π§ Carefully disassemble the phone, disconnect the battery plume and connect the wires from the power supply to it (observe polarity!).
- β³ Charge. 10-15 Then, take the phone and try to turn it on.
π‘
If the battery is swelling, don't try to charge it. It's dangerous: it's a risk of fire or explosion. In that case, only a replacement.
5. Moisture hit: what to do if Xiaomi "sinks"
Moisture is one of the most insidious causes of black screens, and even if the phone hasn't fallen into the water, condensation or high humidity can cause contacts to corrosion.
πΉ First action:

- π¨ You can use a fan at minimum speed (do not direct the air flow directly to the connectors).
πΉ Post-drying check:
1. Turn on your phone. If the screen is up, back up the data right away.
2. Check the operation of all functions: camera, speakers, microphone, sensors.
3 If the screen doesn't turn on, but the phone makes sounds, the problem is in the plume or the matrix.π‘
After getting moisture for a week, watch the phone. Even if it is running, corrosion can manifest later. It is recommended to disassemble and clean the contacts with isopropyl alcohol (90%+).
β οΈ Warning: If you see any stains or stripes on the screen after moisture is injected, the matrix is damaged, and then drying won't help, you need to replace it.
