Introduction: when you need to replace the display and whether to do it yourself

A broken Xiaomi screen is one of the most common breakdowns smartphone owners face. Cracks, broken pixels, a broken touchscreen or a completely black display after a fall make you think about repairing it. But should you change the screen yourself or should you give the phone to the service center?

In this article, we will go through the entire process in detail, from fault diagnosis to final testing of the new display, what tools you will need, how to properly disassemble Xiaomi without damage, where to buy a quality screen module and how to avoid typical errors, and we will compare the cost of self-repair with the prices in services and give an honest answer to the question: "Will amateur activity pay off?"

It is important that you have a model with AMOLED-display (e.g. Xiaomi 12 Pro or Redmi) K50), The replacement process will be more difficult than on budgetary devices with IPS-But even beginners can do it if you follow the instructions.

Diagnosis: Is the display really to blame?

Before ordering a new screen, make sure it's the one that's the problem, and sometimes the symptoms of a "dead" display can be caused by other malfunctions:

• 🔋 Discharged battery – the phone does not turn on, but when connected to charging, an indication appears (battery icon).
• 🔌 A departed plume – the screen flashes, periodically fades or reacts only to a part of the touches.
• 📱 Motherboard problems – the phone vibrates when turned on, but the image is not even on an external monitor (via a monitor) USB-C → HDMI).
• 💧 Moisture infestation - under the screen see divorces, and touchscreen works with delays.

To rule out software failures, try:

1. Connect the phone to the computer and check if it is detected in ADB (Adb devices team).
2. Press Power + Volume up for 10-15 seconds for forced reboot.
3. If you have access to Fastboot, reset via the command: fastboot erase userdata fastboot reboot

⚠️ Warning: If the phone overheats after a fall, smells like a burn or doesn't charge, don't take it down yourself. It could be a short circuit on the board, and attempts to repair without experience will lead to a complete failure of the device.

What tools will be needed to replace the screen

To replace the display with Xiaomi, you need a minimal set of tools. Don't skimp on quality - cheap plastic blades or dull screwdrivers can damage the case or plumes.

In addition, the following may be useful:

• 🧲 Magnetic mat - so as not to lose the screws.
• 🔍 loope USB-microscope – to examine small details (for example, plume contacts).
• 📏 Plastic card - as an alternative to blades for screen separation.

⚠️ Note: If you have a model with an ultrasonic fingerprint scanner (for example, Xiaomi 13 Ultra), when changing the screen, you will need to transfer the scanner from the old module to the new one!

Before disassembly, take a picture of the location of all screws and plumes - this will greatly simplify the reverse assembly.

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

The disassembly process may vary depending on the model, but the overall sequence of actions is the same. 10 Pro (similar to most models) Xiaomi/POCO).

Step 1: Turn off and prepare the phone

Turn off your phone completely. If the screen doesn't respond, hold the power button for 20 to 30 seconds.

1. Take it down. SIM-card and memory card (if any).
2. Warm up the display edge with a hair dryer around the perimeter for 2-3 minutes (keep at a distance of 5-7 cm so as not to overheat).
3. Plug the suction cup on the bottom of the screen (near the charging connector).

Step 2: Separation of the display from the body

Pull the suction cup carefully, creating a small gap, insert a plastic spatula into it, and slowly lead along the edge, separating the glue. Don't put too much effort into it -- if the screen doesn't lend itself, warm up again.

On models with curved display (for example, Xiaomi) 11T Pro) be especially careful - the plumes are located closer to the edges and are easily damaged.

Step 3: Turn off the plumes

Once the screen has separated, place it on a stand (like a phone box), unscrew the screws that hold the metal plate over the plumes, and gently disconnect them with a spatula. There are usually two:

• 📺 Display plume (wide, goes to the top of the board).
• ☝️ Touchscreen plume (thinner, often located nearby).

Step 4: Removing the Old Display

Once the plumes are turned off, you can completely remove the old module. If it's broken, wrap it in tape to avoid cuts.

• 🔊 Speaker and microphone – on some models they are glued to the display frame.
• 📶 Antenna contacts – don’t lose small metal parts.
• 🔋 Battery: If it swells, do not continue disassembly (risk of fire!).

Installation of a new display: nuances and typical errors

Before installing a new screen, check it for defects, such as scratches, broken pixels, or polarizing film detachment. If you bought it on AliExpress, check the kit — some vendors don't put glue or screwdrivers.

Step 1: Transfer parts from the old display

The new module should be transferred:

• 🔊 Top speaker (if it was glued to the frame).
• 📞 Microphone grid (often attached to bilateral tape).
• 👆 Fingerprint scanner (for models with ultrasonic sensor).
• 🛡️ The security frame (if it was on the old screen).

Use a dryer to soften the glue or gently tuck the parts with a spatula. Don't glue the speaker right away - check the new screen first!

Step 2: Connecting the plumes

Carefully connect the plumes to the motherboard in reverse order.

• Contacts are not bent.
• The sleeves were sliding into the sleeves (the snails should be heard).
• The metal plate is fixed with screws (but don’t pull!).

Step 3: Testing before final assembly

Connect your phone to charge and try to turn it on.

• 🎨 Colors and backlights – are there no broken pixels or yellowness.
• ☝️ Touchscreen – Does it respond to touches at all angles.
• 🔊 Sound – is the speaker working (if it has been moved).
• 📶 Sensors – is autorotation and brightness adjustment working correctly.

⚠️ Warning: If the phone doesn't turn on or hangs on the logo after connecting the new screen, it's likely a problem with a plume damage or a short circuit. Turn off the battery for 5 minutes and reconnect. If it doesn't work, check the damage charge.

Step 4: Fixing the display

If the test goes well, you can stick the screen.

1. Double-sided tape is a quick but less reliable way, suitable for temporary repairs.
2. Clay. B-7000 — It is applied with a thin layer around the perimeter, provides a strong fastening.
3. Ultraviolet glue – used in services, requires a UV lamp for polymerization.

After gluing, put the phone under a press (for example, a stack of books) for 1-2 hours.

💡

The most common mistake when changing the screen is uneven gluing, which then causes waves to appear on the display when pressed. To avoid this, use a uniform layer of glue and fix the screen strictly in the center.

Cost comparison: the service center itself vs.

The price of the screen replacement depends on the Xiaomi model and the type of matrix, and the table below is the approximate prices for 2026 (for Moscow and the regions).

Is it worth changing the screen yourself?

• You have a budget-segment model (savings of 1,500–3,000) ₽).
• You are confident in your skills and willing to take risks.
• Found original or quality copy screen (not “nouneim” with AliExpress).

Not if:

• Phone for warranty (self-repair cancels it).
• You have a flagship model with AMOLED and ultrasound scanner.
• There is no time or tools for a careful disassembly.

The average cost savings for self-replacement is 30 to 50 percent of the cost of repairs to the service, but remember, if something goes wrong, you'll have to pay double that.

Frequent problems after screen replacement and how to fix them

Even if you did everything right, you might have problems after you change the display, and we'll look at some of the most common ones and how to fix them.

2. Broken pixels or yellowness

If there are broken pixels or uneven backlights on the new screen:

• 🎨 Run the display test through the engineering menu (##6484## on some models).
• 🔄 If the hardware defect - contact the seller under warranty.

3.The phone does not turn on after assembly

Possible causes:

• 🔋 Battery disconnected – check the contacts.
