How to change the display Xiaomi Mi Max 2 yourself

Xiaomi Mi Max 2 is famous for its huge screen, which has become its main feature, but this parameter makes the device vulnerable to falls. Large format factor increases the impact area, and even a slight collision with a hard surface can lead to cracks or a complete failure of the matrix. Replacing the display on this model is not the most difficult process, but requires increased accuracy and specific knowledge of the design of the case.

Before you start disassembling, you need to understand the difference between the sensor and the matrix. In modern smartphones, including the Mi Max 2, they are combined into a single module, which makes it easier to replace, but makes the component itself more expensive. If the glass is broken, but the image is clear and the touchscreen works, you are lucky, you can do with gluing, but in 90% of cases, the inside suffers from the impact.

In this article, we will take a look at each stage of the repair, from the preparation of the workplace to the final calibration of the touchscreen, you will learn which tools are critical, how to safely disconnect the plumes and what nuances you should pay special attention to not damage other components of the device. Self-repair will save a significant amount of money, but requires patience.

Diagnosis of malfunction and selection of components

The first step should always be a thorough diagnosis. Don't rush to buy parts until you make sure that the problem is in the display, not a software failure or plume. Turn on your phone and carefully examine the screen at different brightness levels. The presence of black spots, stripes or broken pixels indicates damage to the matrix.

If the glass is broken, but the image is perfect, and the touchscreen responds to touch, theoretically you can try to replace only glass. However, for the Xiaomi Mi Max 2, this is often economically impractical due to the complexity of the re-sticking process at home. It is easier and more reliable to purchase a module assembled (screen + touchscreen + frame or without it).

There are many options available in the market, and it's important not to get confused. Original is hard to find, so you often have to choose between quality copies and cheap counterparts. It's critical to buy a framed module, since it's almost impossible to glue a new screen to an old frame without special equipment and glue the first time.

⚠️ Attention: Cheap copies of displays often have incorrect color reproduction and reduced touchscreen sensitivity. Avoid screens with a yellowish tint or too low pixel density.

The table below compares the main types of displays available for this model:

Don’t chase the lowest price, as the controller on cheap screens can work unstable, causing phantom clicks, it is better to overpay 20-30% for a trusted supplier or model labeled High Copy.

Tools and workplace preparation required

You can't have a good repair without a good tool. To disassemble the Xiaomi Mi Max 2, you'll need not only a standard cross screwdriver, but also a number of specialized devices. Prepare the workplace: the table should be well lit and the surface should be clean and slip-free.

• 🛠️ Set of screwdrivers: mandatory presence of a cross screwdriver PH000 or PH00, As the screws in Xiaomi are very small.
• 🔥 Dryer or thermal package: necessary to soften the glue holding the back cover and display module.
• 💳 Plastic cards or mediators: for neat opening of the case without damaging the plastic.
• 🧲 Magnetic mat or organizer: not to lose screws of different lengths that are twisted in the process.
• 🧴 Clay. B-7000 or T-8000: for final fixation of the display module (if it does not come with an already applied adhesive layer).

Pay special attention to the hair dryer. Do not use household hair dryers at maximum power for a long time - they can overheat. Better use a temperature-adjusted building hair dryer, setting a value of about 80-100 degrees Celsius. Overheating can damage the battery or melt internal components.

It is also recommended to use a suction cup to lift the back cover, which allows you to create an initial gap, which then inserts a plastic blade, metal tools are strictly forbidden to use - they can damage the plumes or break a new matrix.

The process of disassembling the body Xiaomi Mi Max 2

Disassembly starts with the device being turned off. SIM-map or leave the tray empty, but make sure the phone is not active.The first step is always to heat the perimeter of the back cover.Warm the edges evenly during the course of the phone. 2-3 minutes without holding the hair dryer for a long time at one point.

Once heated, the suction cup sticks to the bottom of the back cover, just above the Mi logo. Pull the suction cup up, create a gap, and immediately insert a plastic card into it. Keep the map around the perimeter, cutting the glue layer. Be careful at the top where the camera and the plumes are located.

When you remove the back cover, you'll see a metal frame covering the main board, which is secured by a lot of screws around the perimeter, unscrew all the visible screws, including those that can be hidden under stickers or plugs, and carefully remove the metal plate, trying not to touch the main camera plume.

⚠️ Warning: The screws in different corners may be of different lengths. Write or spread them in the order in which they were twisted, so that when assembled, you do not break the board with a too long screw.

Then you have to disconnect the main camera plume and the flashes if they interfere with access to the board, and they're usually pressed by metal clipplates. Bend them carefully, remove the connectors, and put the camera aside. Now access to the board is free.

Disabling plumes and dismantling the old screen

The most critical step is to turn off the plumes. On the main board Xiaomi Mi Max 2 connectors display and touchscreen are located next to each other, they can be closed with a metal protective plate that you need to unscrew.

Use a plastic blade or nail (if possible) to snap connectors. Movement should be from the bottom up or sideways, but not perpendicular downwards, so as not to push the board. The display plume is usually wider and has more contacts than the touchscreen plume.

• 🔌 Disconnect the main board connector from the display module.
• 🔌 Disconnect the touchscreen connector (if it is separate, in some revisions they are combined).
• 🔌 Check if there are additional plumes going to the buttons or speaker that can be pulled.

Once you've shut down all the communications, you can retrieve the old module, and if you've bought a framed screen, it's a simpler process: you have to move the battery, the main board, the child board (with the charging connector) and the camera modules to a new frame, and if the screen is frameless, you have to carefully separate all the components from the old frame, clean them from the glue and fix them on a new one.

When you rearrange the battery, be very careful. Don't bend it or puncture it. In the Mi Max 2, the battery is quite large and sits tightly in the case, often holding on to double-sided tape. To extract it, you can slightly warm the outside of the case in the battery area.

Installation of a new module and assembly of the device

Before the final assembly, you need to test the connection. Don't glue the screen right away! Connect the plumes of the new display to the board, carefully put the board on top and turn on the phone with the power button. Check the performance of the image, colors and, most importantly, the response of the touchscreen.

If everything is working correctly, turn off the phone and start fixing. Apply a thin layer of B-7000 glue around the perimeter of the new frame (unless the glue is in the factory), install the display module with a slight pinch on the edges. Let the glue grip for 10-15 minutes.

Then, put the main board in place with screws, plug all the plumes back in, be careful, install a metal plate, and twist all the screws, make sure that no wires are squeezed.

⚠️ Note: When installing the back cover, make sure that the touchscreen plume does not fall under the edge of the case, otherwise, when closing, it will be clamped and stop working.

The back cover is also planted on the glue. Warm up the edges of the case and the cover itself, apply fresh glue (old is better removed) and press tightly. You can use money bands to pull the case together for the time the glue is drying (about 1-2 hours).

Frequent problems after replacement and their solution

After assembly, there may be nuances that require additional attention, such as if the touchscreen is not working properly or "jumping," perhaps the problem is grounding or poor plume contact. Try reinstalling the connector.

Sometimes there is a problem with the proximity sensor. If the screen does not go out during a conversation, check if the sensor is covered with glue or shifted protective film inside the case. In the Xiaomi Mi Max 2, the sensor is at the top of the screen.

• 📉 Low brightness: may indicate a non-original power controller or software failure.
• 📉 Flickering: often caused by a bad connector press or a marriage of the matrix itself.
• 📉 No sound in the speaker: check if the connector of the sound plume, which often comes complete with the screen or is located next to the camera, is properly standing.

If the image has unnatural colors, you may have Read or Night Mode enabled in the settings. Go to Settings → Screen and check the color scheme. It's also worth checking if the original protective film is installed, which can distort colors.
