Vertical, horizontal or colored stripes on Xiaomi’s screen are one of the most common hardware problems faced by smartphone owners, and the causes can range from software failures to physical damage to the matrix, and in some cases, the defect can be fixed at home, in others, professional repairs will be required.
This article will help you understand why your Redmi is on display, POCO Or Mi has a strip on how to diagnose the problem and what steps to take to solve it. We will look at both software methods (reboot, reset settings) and hardware (check the plume, change the screen), and also give recommendations for preventing the defect from recurring.
Important: if the strip appeared after a fall or impact, there is a high probability of mechanical damage, in which case self-repair can aggravate the situation - it is better to contact the service center.
Reasons for the appearance of stripes on the screen Xiaomi
Stripes on the display rarely occur for no reason, most often due to one of the following factors:
- 📱 Software failure – errors in the graphics driver or firmware (especially after updating) MIUI).
- 🔌 plume problems – oxidation, breakage, or poor contact of the flexible cable connecting the display to the motherboard.
- 💥 Mechanical damage – a fall, impact or heavy pressure on the screen, leading to damage to the matrix.
- 🌡️ Overheating or hypothermia – sudden temperature changes can cause temporary artifacts on the display.
- ⚡ GPU malfunction is rare but occurs on older models (e.g. Xiaomi Mi 5 or Mi 6).
- 🔋 Power problems – unstable voltage from battery or power supply.
The most dangerous bands are those that appear after physical impact (hit, fall), they often signal cracks in the matrix or damage to the plume, which requires replacement of parts, and if the band has arisen for no apparent reason, try software methods of elimination first.
Pay attention to the nature of the strip:
- 🔴 Colored stripe (red, green, blue) - most often indicates problems with the plume or matrix.
- ⚪ White or gray band - may be a consequence of software failure or overheating.
- 🔄 Shimmering stripe – usually associated with unstable eating or damage to the graphics chip.
Diagnosis of the problem: how to determine the cause of the stripes
Before you start repairing, you need to understand what exactly caused the strip to appear.
- Reboot your smartphone – if the bandwidth disappeared, the problem was temporary (such as a graphics driver failure).
- Check in Safe Mode: Press the Power button → Hold your finger on the "Stop" option, and you'll be asked to go to Safe Mode, confirm. If the band is gone, it's the third-party app's fault.
Connect to another power source
Check on another display.
USB-C → HDMI
If the band is still in all modes, it's a hardware problem, and if it disappears in safe mode or after rebooting, it's probably the software's fault.
☑️ Diagnostic stripes on the screen Xiaomi
| Symptoms. | Probable cause | Recommendation |
|---|---|---|
| The band appeared after the update MIUI | Failure of firmware or driver | Reverse the update or reset the settings |
| The strip flickers when you press the screen | Problems with plume or contacts | Take the phone apart and check the plume |
| Colored stripe after fall | Damage to the matrix or plume | Replacement of screen or plume |
| The strip disappears when heated/cooled | Unstable plume contact | Reconnect the plume or replace |
⚠️ Warning: If the band appears after moisture is injected, turn off the phone immediately and dry it for 24 to 48 hours!
Software methods of eliminating bands
If the cause of the band is a software failure, try the following methods:
1. Resetting settings to factory
This is a radical but effective way to fix software errors. Make sure to back up important data before resetting!
- Go to Settings → About Phone → Backup and Reset.
- Select Settings Reset.
- Confirm the action and wait for the reboot.
For manual firmware download the official version MIUI From Xiaomi and follow the instructions for your model.
Screen calibration
Sometimes the stripes are caused by the wrong color rendering. Try resetting the display settings:
- Go to Settings. → Screen.
- Select Color Mode and set Standard.
- Turn off options like Auto Brightness and Read 2.0.
💡
If after resetting the band remained, but changed color or position, the problem is precisely hardware - do not waste time on software methods.
4. Virus testing
Rarely, malware can affect the graphics subsystem: scan your phone with an antivirus (such as Malwarebytes or Dr.Web) and remove suspicious apps.
Hardware methods: what to do if the strip is left
If the software didn't work, the problem is the hardware. Let's look at the possible repair options.
1. Checking and replacing the display plume
The plume is the most vulnerable part of Xiaomi's screen design, and it wears out, oxidizes, or moves away from the connector over time to check the plume.
- Turn off the phone and remove the back cover (a mediator or plastic shoulder blade will be required).
- Disconnect the battery (required!).
- Find the display plume (usually located under metal protection).
- Take it off and reconnect it.
If the lane disappeared after reconnection, the problem was in contact. If not, the plume could have damaged and needs to be replaced, POCO X3) — 300 to 800 rubles.
⚠️ Attention: When disassembling Xiaomi, be careful with thin cables under the battery - they are easy to damage! If you are not confident in your abilities, you should contact the service.
Replacement of the display module
If the band appeared after a hit or fall, the matrix is likely damaged, in which case the entire display module (screen) will need to be replaced. + sensor + The price varies:
- 📱 Xiaomi Redmi 9/9A/9C — from 2 500 before 4 000 ruble.
- 📱 POCO X3/X4 — from 4 000 before 6 000 ruble.
- 📱 Xiaomi 11/12 series 8 000 before 15 000 ruble.
When replacing the screen, pay attention to the originality of the parts. Non-original displays can have worse color reproduction or sensor issues.

3. Graphics chip repair
On older models (Mi 5, Mi 6, Mi 8) bands may appear due to overheating or detachment of the graphics chip (GPU). This is a complex repair that includes:
- 🔥 Chip soldering (requires professional equipment).
- 🧊 Replace thermopaste (if the cause is overheating).
The cost of repairing it starts at 5,000 rubles, and not every service is taken for it, and it's often more cost-effective to sell your phone for parts and buy a new one.
Frequent mistakes in self-repair
Trying to eliminate the bandwidth on Xiaomi’s screen without proper experience often leads to even more serious problems.
- 🔌 Disassembly without turning off the battery - the risk of short circuit.
- 🔨 Using metal tools – you can damage the board or plumes.
- 💦 Moisture on contacts – even drops of sweat can cause corrosion.
- 🔄 Incorrect assembly – forgotten screws or unconnected plumes.
- 📱 Installation of non-original screen without compatibility check.
On Xiaomi models with AMOLED-screens (e.g. Mi 11, Redmi) K40) It is especially dangerous to damage flexible plumes - they are thinner than on the surface. IPS-displays, and worse tolerate multiple connections.
⚠️ Warning: If the phone stops turning on after disassembly, do not try to connect it to charging immediately.First check if there are any foreign objects (screws, pieces of plastic) left inside and if the board is not damaged.
Prevention: How to avoid stripes on the screen
Preventing the lanes is easier than eliminating them.
- 🛡️ Use a cover and protective glass – this will reduce the risk of damage when falling.
- 🔋 Avoid overheating – do not leave your phone in direct sunlight or near heat sources.
- 💧 Keep away from moisture – even a little humidity can cause contact oxidation.
- 🔄 Update on time, but don’t install the beta version. MIUI main-phone.
- 📦 Keep your phone in a dry place – high humidity accelerates the corrosion of plumes.
If you drop your phone frequently, consider Corning Gorilla Glass-protected models (e.g., the Gorilla Glass, POCO F4 Xiaomi 12T). They are better able to handle mechanical loads.
💡
Most vulnerable to model strips with removable batteries (for example, Redmi) 4X, Redmi 5A) — Their plumes wear out faster with frequent disassemblies.
When to contact the service center
Self-repair is only justified in the case of software failures or simple hardware problems (for example, reconnecting the plume).
- 💥 The strip appeared after a strong impact or fall from a height.
- 🔥 The phone overheats, turns off or reboots spontaneously.
- 🛠️ Requires replacement of the matrix or soldering of chips (without special equipment this is impossible).
- 💦 The phone was in water or other liquid.
- ⚡ The strip is accompanied by other artifacts (flickering, color distortion).
The cost of diagnostics in official Xiaomi service centers is usually free.
