A broken smartphone display is not just an aesthetic defect, but a serious problem that prevents the full use of the device. Cracks on the glass can grow, damaging the matrix, and a broken touchscreen makes the gadget almost useless. Many owners immediately carry the phone to the service center, but replacing the screen Xiaomi 5 allows you to save a lot of money.
The procedure requires precision, patience and a minimal set of tools. The display module in this model is a single design, which simplifies the replacement process, but makes it difficult to disassemble the body. In this material, we will discuss all the steps of work in detail, from the preparation of the workplace to the final inspection.
It is worth noting that the success of the operation depends not only on the quality of the new part, but also on strict adherence to the sequence of actions. Mishandling plumes or using the wrong tools can lead to failure of other components of the smartphone.
Diagnostics of malfunctions and selection of spare parts
Before starting disassembly, you need to accurately determine the nature of the damage. Often users confuse the damage to the external glass (touchscreen) with the failure of the matrix itself. If the image on the Xiaomi Mi 5 is bright, without spots and stripes, but the phone does not respond to touch, you may need to replace only the touchscreen. However, if you see black spots, stripes or image completely missing, you need a complete replacement of the display module.
When choosing a new part, it is important to pay attention to the type of matrix. Original screens are usually made using IPS or AMOLED technology (depending on the version of the smartphone); Cheap counterparts can have worse color reproduction and reduced sensor sensitivity. Xiaomi 5 is characterized by a problem with unplugging the plume when using non-original components of low quality.
Check the kit before you buy. A quality module often comes with a frame installed and adhesive layer applied, which makes assembly much easier. Cheap options can come in "naked" form, which will require glass regluing and the use of special glue B-7000 or analogues.

Tools and workplace preparation required
You can't have a good repair without the right tools, you'll need a special set to open your smartphone, you'll have a thin metal or plastic blade to snap the body, and you'll never want to use knives or sharp objects, because you're at risk of damage to the internal components or injury.
To work with screws you will need a cross screwdriver PH000 or PH00. screws in Xiaomi 5 are very small, and losing even one of them can lead to a backlash of the case. Also prepare tweezers with curved ends to work with plumes and a plastic card to disconnect the connectors.
Pay special attention to the heating of the case. The glue holding the back cover melts at about 80-90 degrees. You can use a building hair dryer, exposed to minimum power, or a special heating pad. A normal hair dryer may not cope with the task or overheat.

The process of disassembling the Xiaomi 5 body
The first step is always to extract SIM-This obvious but often forgotten action can cause damage to the tray when you try to remove the lid, then warm up the perimeter of the back cover. 3-5 cm from the hull during 2-3 minutes, constantly moving the airflow.
Insert a plastic card or spatula into the gap between the frame and the back cover. Carefully guide the tool along the perimeter, trying not to dive deeper than 3-4 mm, so as not to damage the fingerprint scanner plume or button connectors. The Xiaomi 5 is built on adhesive basis, so smooth but confident movements are required.
When you remove the back cover, you have access to the insides, and the first thing you need to do is turn off the battery, and then you have to remove the metal plate that covers the main plumes, and you have to twist the locking screws, and then you can safely work with the other components after you turn off the battery.
โ ๏ธ Warning: Never pull on plumes with your fingers or tweezers. connectors are very fragile, and sloppy movement can cut off contacts, which will require soldering at the micro level.
Next, unscrew all the visible screws that attach the motherboard and the lower board. Notice the screws of different lengths: write down or schematically note where the screw was twisted. Long screws in the holes for short can break through the tracks on the board.
โ๏ธ Preparation for disassembly
Dismantling of the old display module
When the motherboard is free of mounts, it needs to be gently lifted up. Under it or near it are the plumes that go to the display. Xiaomi 5 uses two main plumes: one for the image and one for the touchscreen (or combined, depending on the revision).
The next step is to remove the speaker and the vibrator, if they're attached to the display module. In some assemblies, these elements remain on the frame, in others, they are attached to the screen. Check for screws around the perimeter of the screen. If the screen is not removed, you may have missed the screw under the logo or sticker.
When you remove the old module, act slowly. The plumes can be glued to the frame. Use a hair dryer to lightly heat the bottom of the smartphone, where the plume passes, to soften the glue. A sharp jerk is guaranteed to lead to a cliff.
What to do if the plume is broken?
After successfully removing the old module, carefully clean the frame of the glue and dust residues. The surface must be perfectly smooth, otherwise the new screen will be skewed or air bubbles will be visible. Use isopropyl alcohol and a lilac wipe.
Installation of a new screen and assembly
Before final assembly, it is recommended to conduct a test connection. Connect the plumes of the new screen to the motherboard without fixing them with screws or gluing the module itself. Turn on the phone and check the touchscreen, the presence of broken pixels and the brightness sensor.
If the test is successful, apply a new layer of glue (B-7000 or special glue for displays) to the frame of the new module or on the body of the smartphone. evenly distribute the glue in a thin layer and let it dry for 1-2 minutes to the state of "Velcro".
Place the module in place with the perimeter tightly pressed, make sure the plumes are placed in the channels that are intended for them and not clamped, then put back the metal protection, twist all the screws and plug the battery.
| Phase | Action. | Implementation time | Difficulty |
|---|---|---|---|
| 1 | Disassembly of the hull | 10-15 minutes | Medium |
| 2 | Shutting down the plumes | 5 minutes | Tall. |
| 3 | Replacement of the module | 10 minutes | Low. |
| 4 | Final assembly | 15 minutes | Medium |
Typical errors and precautions
One of the most common mistakes is ignoring the heating of the case. Trying to open a cold phone by force leads to cracks in the back cover that can go beyond the screen. Always warm the glue to a state where it becomes elastic.
Another problem is the loss of screws. Xiaomi 5 uses screws of different sizes for different nodes. If you screw a long screw into a hole for a short one, you can damage the board or the screen on the back. Sorting screws on a magnetic mat or a piece of paper with a drawn circuit is mandatory.
Remember static electricity. Before touching the internal components of a smartphone, touch a grounded metal object or use an antistatic bracelet. A static discharge can instantly disable a power controller or touchscreen.
โ ๏ธ Warning: If the screen doesn't light up after assembly, don't panic. Check the density of the connectors. Sometimes you have to press the connector until you click.
๐ก
Use tape or paint tape to temporarily fix the plumes during assembly until metal protection is installed.
Checking and calibration
After assembly, you need to check not only the visual part, but also the functionality. Turn on the phone and open the "engineering menu" to check the sensor. Enter the code ##6484## in the dialer to enter mode. CIT (CIT - Customer Integration Test).
In the test menu, select "Touchpanel." Swipe your finger across all areas of the screen. The line should be drawn without breaks or jumps. Pay special attention to the edges of the screen, where defects are often encountered in poor build.
Also check the proximity sensor and autobrightness, hold the phone to your ear during the call, the screen should go out. If this does not happen, it may be contaminated with glue or displaced during assembly, in which case you will need to re-disassemble and clean the area of the sensor.
๐ก
A quality screen replacement returns 95% of the original functionality to the smartphone, unless other components were damaged during disassembly.
The final step will be to check the operation of Wi-Fi and Bluetooth. antenna modules in Xiaomi 5 are located close to the disassembly zone, and careless handling could disrupt the contact of the antenna.
