Replace the screen on Xiaomi Redmi 6A with your own hands

Modern smartphones, despite the strong materials of the case, remain vulnerable to falls and mechanical damage. Model Xiaomi Redmi 6A, with a budget cost, often becomes the object of careless handling, which leads to cracks in the glass or complete failure of the matrix. If you are faced with such a problem, you should not immediately carry the device to the service center, since the procedure for replacing the module is quite affordable for self-implementation at home.

Recovery of the display module requires accuracy, a minimum set of tools and a clear understanding of the sequence of actions. It is important to understand that in this model, the screen is a single node, including glass, the touch layer and the matrix itself, which simplifies the replacement process, since it does not require separation of components by adhesive separator.

Before starting work, you need to make sure that there is an original or high-quality compatible spare part, since cheap analogues can differ significantly in color reproduction and touchscreen sensitivity. Properly carried out replacement will prolong the life of your gadget and return it to its original appearance without overpaying the masters.

Tools and workplace preparation required

The quality of the repairs is directly dependent on preparation. You need a clean, well-lit space where small screws and plumes do not get lost among the garbage. To work with the Redmi 6A, you do not need complex machines, just a basic set that can be purchased from any radio parts store or ordered online.

The main tool for opening the case will be a thermophen or, in extreme cases, a regular hair dryer that can heat the adhesive base to 80-90 degrees. Also, there is a suction cup to pull the screen, plastic mediators (scapula) for neat snapping latches and a set of screwdrivers, including cross and flat.

• 🔧 Precision screwdriver set (PH000, PH00) motherboard-screw.
• 🔥 Thermophen or building hair dryer for softening the adhesive around the perimeter of the housing.
• 🧤 Antistatic gloves and tweezers for working with small components.
• 💧 Isopropyl alcohol and new B-7000 glue-fixing.

Pay special attention to lighting: the shadow of the hand should not fall on the work area, as this can damage the plumes with insufficient visibility. It is recommended to use an antistatic mat or just a clean fabric, so as not to scratch the back cover of the smartphone during the dismantling process.

Dismantling the old panel and disconnecting the plumes

The process of dismantling Xiaomi Redmi 6A Starts by turning off the device and removing the tray SIM-Then you need to warm up the perimeter of the screen, directing the flow of hot air evenly on all sides during the course of the day. 2-3 Don't hold the hair dryer too close to overheat the internal components, but ensure that the temperature is sufficient to soften the glue.

Once the body is warmed up, place the suction cup at the bottom of the screen and gently pull up, creating a small gap. Insert a plastic blade into the resulting gap and, without putting too much effort, run it along all the faces, freeing the display module from the frame. It is important not to damage the plume connecting the screen to the board, which is located at the top.

⚠️ Warning: Don't try to take the screen off completely until you turn off the battery! a sharp jerk can break the touchscreen plume or damage the connector on the motherboard.

Once the module is snapped around the perimeter, unscrew the screws that lock the protective metal plate covering the connectors. Carefully remove the plate with tweezers and disconnect the display plume, pulling it up with a plastic blade, only after that you can completely remove the damaged screen from the case.

Installation of a new display module

Before installing a new display module, you should carefully clean the smartphone frame of the remnants of old glue. Use isopropyl alcohol and a plastic card to do this, avoiding the use of metal objects that can scratch the plastic or damage the side buttons.

Try on the new screen, making sure it fits perfectly in the frame and the holes under the speaker and the front camera match. If the new module does not have pre-installed glue, apply a thin layer of special adhesive B-7000 around the perimeter of the frame, avoiding hitting the substance in the center of the screen or on the camera.

Connect the plume of the new display to the motherboard, making sure of the characteristic click, and return to place the protective metal plate, fixing it with screws. Before the final assembly, it is recommended to temporarily turn on the device to check the operability of the touchscreen and the absence of image defects (broken pixels, spots).

💡

Check the touchscreen by opening notes and drawing lines throughout the screen area – this will help to identify insensitive zones before the final gluing of the case.

Compatibility table and screen characteristics

When choosing a spare part, it is important to focus not only on the model name, but also on the marking, since different types of matrixes can be used in different revisions of the Xiaomi Redmi 6A. Below is a table of the main characteristics and compatible articles that are found in the market.

It is worth noting that the 1440x720 resolution is standard for this model, and installing a matrix with other parameters can lead to incorrect display of the interface. Always check the compatibility of the plume: its length and location of contacts must be completely the same as the original.

Final assembly and seal check

After a successful test of the new screen, you can start the final assembly. Apply glue to the frame of the case if it has not been applied earlier, and tightly press the display module. For better adhesion, it is recommended to lock the smartphone with stationery gums or put under the press for 15-20 minutes.

Set the back cover, preheat its edges to activate the adhesive layer, make sure that all latches around the perimeter of the housing closed with a characteristic click, indicating a tight fit.

⚠️ Warning: Do not turn on the device immediately after gluing, let the glue dry completely during the 1-2 hours, otherwise the pressure during heating can push the module outwards.

Complete polymerization of the adhesive takes about 24 hours, so on the first day, avoid getting moisture and heavy loads on the screen. After drying, wipe the case with a microfiber and check the operation of all buttons and speakers.

Common Errors and How to Resolve Them

In the process of self-repair, beginners often make mistakes that can lead to the need for redisassembly. One of the most common problems is incomplete connection of the plume, which causes no image or a non-working touchscreen.

Another common mistake is to use too much glue, which can squeeze into the body and damage other components, and it is also dangerous to use metal tools to snap the screen, as this is almost guaranteed to damage the matrix.

• 🚫 Ignoring screen check before final gluing.
• 🚫 Use of aggressive solvents instead of isopropyl alcohol.
• 🚫 Excessive heating of the body, leading to deformation of the plastic.

If you notice dust under the glass after assembly, do not try to remove it immediately - it is better to wait for the glue to dry completely, so as not to disturb the tightness. In most cases, small specks of dust do not affect the operation of the device and become noticeable only when the screen is turned off.
