A fall from a height, a blow, or even strong pressure on the display can cause cracks, dead pixels, or complete sensor failure. If your phone has stopped responding to touches, colored stripes have appeared, or the image is flickering, you most likely need display replacement.
In this article we will analyze all the nuances of the procedure: from choosing the original module to step-by-step disassembly Redmi Note 9. You will learn how much repairs cost at service centers, what tools you will need for replacement yourself, and how to avoid common mistakes that can damage your phone. And if you are not confident in your abilities, we will tell you how to choose a reliable specialist.
When a display replacement is needed: main symptoms of a malfunction
A crack on the screen does not always mean that the module must be completely replaced. Sometimes the problem lies in the cable, controller, or even a software glitch. Before ordering a new display, check the symptoms:
- 🔧 Cracks with sensor disruption — if the screen responds to touch only in certain areas or does not work at all, the touch layer is most likely damaged. It is impossible to restore it.
- 🎨 Color streaks or artifacts — vertical/horizontal lines, flickering or color distortion indicate damage to the matrix or cable.
- 🔄 "Dead" pixels — black or colored dots that do not disappear when rebooting. If there are few of them, you can continue to live with them, but if there is massive damage, the display must be replaced.
- 💥 Black screen when the phone is working — if the smartphone vibrates, makes sounds, but there is no image, the problem may be in the backlight, cable, or the matrix itself.
It is important to distinguish hardware faults from software ones. For example, if the screen Redmi Note 9 does not turn on after a fall, but when connected to a PC, the computer detects it - this is a mechanical failure. And if your phone stops responding to touches after updating MIUI, try resetting the settings via Recovery Mode (press Power + Volume up).
⚠️ Attention: If after an impact the phone overheats, quickly discharges or does not hold a charge, the problem may not be in the screen, but in the battery or motherboard. In this case, self-repair may result in a short circuit!

Selecting a display for Xiaomi Redmi Note 9: original vs. analogue
Not only the appearance of the phone, but also its functionality depends on the quality of the new screen. There are three types of displays on the market for Redmi Note 9:
| Display type | Price (2026) | Pros | Cons |
|---|---|---|---|
| Original (OEM) | 5 000 — 7 500 ₽ | 100% compatibility, perfect color rendering, long service life | High cost, difficult to find in small towns |
| Premium-class analogue | 3 500 — 5 000 ₽ | Good build quality, color rendition close to the original | May require sensor calibration, shorter lifespan |
| Budget analogue | 1 500 — 3 000 ₽ | Low price, fast delivery | Poor sensor sensitivity, distorted colors, risk of peeling |
When choosing, pay attention to display article number. For Xiaomi Redmi Note 9 (model M2003J15SC) the original module is marked DM-T60-P or DM-T60-P-1. Analogues can be designated as For Xiaomi Redmi Note 9 LCD, but without mentioning OEM.
Critical: Cheap displays often come without pre-applied tape to protect the cables. If you install such a module, be sure to purchase copper tape (For example, 3M 8810) - it will prevent short circuits during assembly.
Before purchasing, check the seller's reviews on the marketplace. Often, low-resolution counterfeits are sold under the guise of “original” displays (for example, HD+ instead of FHD+).

Step-by-step instructions: how to replace the display on Redmi Note 9
The screen replacement process takes 1–2 hours and requires care. Follow the instructions strictly step by step so as not to damage the cables or flexible cables.
Step 1: Turn off and warm up your phone
Turn off completely Redmi Note 9 and place it face up. Heat the edges of the display around the perimeter with a hairdryer for 2-3 minutes, holding the nozzle at a distance of 3-5 cm. The glue should become soft, but not melt.
Step 2: Detach the display
Attach the suction cup to the bottom of the screen (where the charging connector is) and gently pull it up. Insert a plastic spatula into the resulting gap and slowly move it along the edge, separating the display from the frame. Do not use excessive force - there are trains running inside!
Step 3. Disconnecting the cables
After the screen is raised 45°, you will see three cables:
- Display cable (widest).
- Sensor cable (thin, with metal protection).
- Front camera and sensor cable (small, right).
Unscrew the metal plate covering the connectors and carefully disconnect the cables with a spatula. Don't pull the wires!
Step 4: Install a new display
Transfer all the details from the old one to the new screen: speaker, front camera, light sensor and gaskets. Connect the cables in reverse order and secure them with a metal plate. Before final assembly, check the functionality of the screen by connecting the phone to a charger (do not turn it on without the back cover!).
Step 5. Gluing and assembly
Apply new adhesive (LOCA or double-sided tape) to the phone frame, carefully place the display and press. Use a roller or credit card to spread the glue evenly. Tighten all screws and check the sensor for any dead zones.
What should I do if the screen does not work after replacement?
1. Check whether the cables are tightly seated in the connectors. Sometimes they fall off during assembly.
2. Make sure that the metal plate securing the cables is screwed in until it stops.
3. If there is an image, but there is no reaction to touch, the touch cable may be damaged. Try replacing it separately.
4. If the screen flickers or shows artifacts, the problem is in the matrix or controller. In this case, diagnostics at the service center is needed.

Common mistakes when replacing a display and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to additional breakdowns. Here are the most common mistakes and ways to prevent them:
- ⚡ Hairdryer overheating the screen — if the temperature exceeds 100°C, the plastic clips of the housing may become deformed. Use thermocouples or an infrared thermometer for monitoring.
- 🔌 Damage to cables — never pull on the wires! Disconnect the cables only with a plastic spatula, having first unscrewed the fixing plate.
- 🧲 Lost screws - in Redmi Note 9 screws of different lengths are used. If you mix them up, you can damage the motherboard. Store them in separate containers.
- 🎨 Uneven application of glue - If you use too much LOCA, it may leak inside and damage the display. For beginners, it is better to choose double-sided tape.
- 🔋 Working with the battery on - although Redmi Note 9 It has short circuit protection, so it's not worth the risk. Disconnect the battery before starting repairs.
Another common problem is sensor not working after replacement. This may happen due to:
- Poor contact of the cable (check if it fits tightly in the connector).
- Damage to the touch controller on the motherboard (diagnostics required).
- Display incompatibility (cheap analogues may not support multi-touch).
⚠️ Attention: If after assembly the phone does not turn on, but when connected to a charger the indicator shows, there is a problem with the power cable or the battery. Do not try to turn it on repeatedly: this may burn the charging controller!
Frequently asked questions (FAQ)
Is it possible to replace only the glass and not the entire display?
Technically yes, but it is very difficult and not always justified. B Redmi Note 9 glass is glued to the matrix (technology OGS), and replacing it requires special equipment (laminator, UV lamp) and experience. In 90% of cases it is cheaper and more reliable to replace the entire module.
How long does it take to replace a display in the service?
At official centers Xiaomi repairs take 1–3 days (including diagnostics). In local workshops - from 30 minutes to 2 hours. If you are promised a replacement in 10 minutes, this is a reason to be wary: most likely, they use low-quality glue or do not check the performance of the screen.
Why does the battery drain quickly after replacing the display?
This can happen for two reasons:
- The new screen has higher power consumption (typical of cheap analogues).
- During disassembly, the battery cable or power controller was damaged. In this case, diagnostics is needed.
Check your phone settings: sometimes after repair the battery calibration gets lost. Reset battery statistics to Settings → Battery → Three points → Calibration.
Can I use a phone with a cracked screen?
It is possible, but with reservations:
- If the cracks are only on the glass and the sensor is working, the risk is minimal, but the fragments can injure your fingers.
- If artifacts or flickering appear, the matrix is damaged, and over time the problem will worsen.
- If the screen does not respond to touches, it is almost impossible to use the phone (except through an OTG mouse).
Remember: cracks break the seal of the case, and moisture or dust can get into the phone, which will lead to corrosion of the board.
Where to buy an original display for Redmi Note 9?
Original spare parts can be ordered:
- On the official website Xiaomi (section "Spare parts").
