Replacement of the display on Xiaomi Redmi 9: detailed instructions with photos and videos

Why Xiaomi Redmi 9 Screen Breaks and When to Change It

The Redmi 9 screen is one of the most vulnerable parts of the smartphone. Even when used carefully, the display can fail due to a fall, severe pressure or factory defect. Typical signs of failure: cracks in the glass, flickering images, stripes, broken areas of the touch screen or no picture at all when the sound is working. If the screen crashes, but the sensor responds to touch, the problem can only be in the protective glass. But most often the entire module is damaged, and then a complete replacement of the display is required.

Many users are afraid to disassemble the phone themselves, fearing that it will break completely, but with the right approach and the necessary tools, you can replace the screen with a Redmi 9 at home, which will cost less than in a service center, where you take from 1,500 to 3,000 rubles for work, the main thing is to take your time, follow the instructions and avoid common mistakes, which we will discuss below.

• 📵 The touchscreen doesn’t work – it almost always requires replacing the entire display module.
• 🖥️ Image distorted or missing - problem in the matrix or plume, need diagnostics.

If you're not sure about your abilities, you should consult the professionals, but if you're willing to take a chance, read on. We'll tell you how to change the display on Xiaomi Redmi 9, what tools you need and what to look for when buying a new screen.

What tools are needed to replace the Redmi 9 display

Without special tools, it is almost impossible to replace the screen with Xiaomi Redmi 9, and you will need a minimum set that can be bought in online stores (for example, on AliExpress or Beru) or in radio stores.

• 🔧 Plastic blades (mediators) - for careful smearing of the body and disconnection of plumes.
• 🔨 The screwdriver (PH00 or PH0) — squirt.
• 🧲 Magnetic mat or organizer – to avoid losing small details.
• 🔥 Dryer or thermoair station - to soften the glue under the screen.
• 📏 Suction cups (1-2 - Helps to raise the display after heating.
• 🧴 Isopropyl alcohol (90%+) — glue-cleaner.
• 🎨 Double-sided tape or glue B-7000 — fixate.
• 🔍 Lupe or magnifying glass - for working with small connectors.

If you plan to do repairs regularly, it makes sense to buy a replacement screen kit — it will cost less than buying all separately. For a one-time repair, you can do with a minimum set of screwdrivers, mediators, hair dryers and suction cups.

Important! Don't use metal blades or knives, they can damage the plumes or the body of the phone, and don't overheat the screen with a hairdryer: the optimum temperature is 60-80°C. If you overheat, you can melt plastic parts or damage the battery.

💡

Before starting work, completely discharge the battery (up to 10-15%) - this will reduce the risk of fire when heating the screen with a hairdryer.

How to choose a new display for Xiaomi Redmi 9: original vs. copy

The quality of the new screen is not only the look of the phone, but also the work of the phone. There are three types of displays on the market for the Redmi 9:

1. Original (OEM) - taken from other phones or supplied by official distributors, the most expensive, but guaranteed compatible.
2. High quality (A+) copies are almost the same as the original, but they are cheaper.
3. Cheap copies (A-, B, C) – may have problems with color reproduction, brightness, or touchscreen.

The cost of displays varies from 1,500 to 4,500 rubles depending on the type and seller.

Where to buy it?

• 🛒 AliExpress – a great choice, but a long wait (2-4 weeks).
• 🏬 Local parts stores – you can check the quality before buying.
• 🌍 Specialized sites (e.g. Fixez, Mobile-Repair) – fast delivery, warranty.

Before buying, check if the display is compatible with your Redmi 9 (e.g. Redmi 9C, Redmi 9A or Redmi 9T – they have different screens!) and check if the adhesive tape is included for fixing – if not, you will have to buy it separately.

Step-by-step: how to disassemble Xiaomi Redmi 9 and remove the old display

Before starting work, be sure to turn off the phone and remove it. SIM-Also prepare the workspace, which should be clean, well lit and draft-free (so that dust doesn't spread:

Turn off the phone and remove it. SIM-map

Prepare tools and workplace

Take a picture of the original state of the phone (in case of warranty disputes)

Wear an antistatic bracelet (optional, but recommended)

-->

1. Remove the back cover. Unscrew the two screws at the bottom of the phone (near the USB-C connector). Then gently tuck the lid with a plastic blade starting at the corners. Be careful, the lid is attached to latches that are easy to break.
2. Turn off the battery. Once you take off the lid, you'll see the battery. Disconnect its plume from the motherboard with a plastic blade. Don't use metal tools! It can cause a short circuit.
3. Heat the screen. Turn on the dryer at medium power and warm the screen evenly for 2-3 minutes, holding it at a distance of 5-7 cm. The glue should become soft, but not melted. Check the temperature with your hand - the display should be warm, but not hot.
4. Screen tampering. Stick the suction cup to the bottom of the display and gently pull up. Insert a plastic blade into the resulting slit and slowly guide it around the perimeter, separating the screen from the body. Take your time — if the glue doesn't lend itself, warm it up again.
5. Disconnect the plumes. Once you take the screen off, you'll see 2-3 plumes connecting it to the motherboard. Carefully disconnect them with a shoulder blade. Remember or photograph the location, and when you assemble them, you'll need to plug them back in the right order.

⚠️ Attention, don't pull the screen by force, it can damage the plumes or tear off the connectors. If the display doesn't respond, warm it up again with a hair dryer.

After removing the old screen, clean the case of glue residues with isopropyl alcohol and a napkin without pile. Do not use acetone or other aggressive solvents - they can damage the plastic.

💡

The hardest part is separating the screen from the body, and if you've never done that, practice on an old phone or watch a video manual before work.

Installation of a new display and assembly of the phone

Now that the old screen is off, you can start installing a new one, and it's important to take your time and watch every step of the way.

1. Check the new display. Connect the new screen to the motherboard before you install it (without fixing it!) and turn on the phone. Make sure the image is clear, there are no broken pixels, and the touchscreen works without delay. If there is a problem, return the display to the seller.
2. Apply glue. If you have duct tape on the screen, stick it around the perimeter of the body, if you don't, apply a thin layer of B-7000 glue or double-sided tape. Don't overdo it, excess glue can go over the edges and get the screen dirty.
3. Install the display. Carefully put the new screen in place, combining the speaker and camera holes. Start at the top and gradually press it against the body so that there are no bubbles. Don't push too hard, you can damage the matrix.
4. Connect all the plumes to the motherboard in the same order they were turned off, make sure the connectors are snapped, they should sit tight, without backlash.
5. Put the battery back in place and plug it in, then close the back cover with all the clips, and spin the screws, turn the phone on and check the screen again.

⚠️ Attention! If the screen doesn't work after assembly or the phone doesn't turn on, don't panic:

• 🔌 The plumes are connected incorrectly or not to the end.
• 🔋 Battery's not connected.
• 📱 Damaged motherboard (if the phone fell from a high altitude).

Check all connections and repeat the assembly if necessary.

If done right, your Xiaomi Redmi 9 is ready to go again! all that remains is to adjust the touchscreen sensitivity (if necessary) and install the safety glass.

Frequent Display Replacement Mistakes and How to Avoid Them

Even skilled craftsmen sometimes make mistakes that lead to additional problems, and here are the most common ones and ways to prevent them:

• 🔥 If you keep the dryer too close or if you keep one place warm for too long, you can melt plastic parts or damage the battery. Solution: heat evenly, keep the dryer 5-7 cm away, and take breaks.
• 🧲 Loss of screws or parts. Small screws are easily lost, and without them you can't build a phone. Solution: use a magnetic mat or organizer for the parts.
• 📱 The plumes are very fragile, they're easy to tear or bend. Solution: just disconnect them with a plastic blade, no jerks.
• 🎨 Uneven adhesion of the screen. If the screen is glued to the curve, there will be gaps or skews. Solution: carefully combine the speaker and camera holes before fixing.
• 🔋 Short circuit. If you accidentally close the contacts on the board, the phone may fail. Solution: work in an antistatic bracelet and don't use metal tools.

Another common problem is that the touchscreen is broken after replacement, and this can be due to:

• Incorrectly connected plume (check if it sits tightly in the connector).
• Damaged connector on the motherboard (a soldering station is needed for repair).
• The rejected display (return it to the seller).

If the screen is working after the replacement, but the image is distorted (strips, flickering, wrong colors), the most likely problem is the matrix incompatibility. Make sure you buy a display for your Redmi 9 model (for example, the Redmi 9C and Redmi 9A have different screens!).
