Smartphone Xiaomi Redmi Note 6 Pro, released in 2018, has proven to be a reliable device with an excellent camera, but its glass body and large display make the gadget vulnerable to falls. Broken glass or leaky matrix module is not just an aesthetic defect, but a serious problem that prevents the full use of the device. Many owners immediately carry the phone into service, but self-replacement of the screen on the Redmi Note 6 Pro is quite real with the accuracy and the right tools.
Before you start disassembling, you need to clearly define the nature of the damage, because it depends on the amount of work and the cost of spare parts. If the surface is cracked, but the sensor is working perfectly and the image is not distorted, you probably got away with replacing only the external glass (touch screen).
It's important to understand that the repair process requires patience and technology to avoid damaging the plumes or breaking the back cover that's glued to this model. The quality of the parts is crucial: the original displays deliver colors accurately, while cheap copies can have poor color reproduction and reduced safety margin. In this article, we'll take a look at all the steps from the preparation of the workplace to the final functionality check.
Diagnosis of damage and selection of components
The first step in restoring the Xiaomi Redmi Note 6 Pro is accurate diagnosis. Often users confuse damage to the oleophobic coating with cracks, so carefully inspect the device in good light. If (cracks) only go over the surface and do not penetrate deep, and the image below them does not distort, this is a good sign. However, if you see purple or black spots blurring over time, this indicates damage to the OLED or IPS matrix, which requires a complete replacement of the module.
There are many options on the market when choosing a new part, and it is important not to get confused in terms: Original displays are labeled by the manufacturer and often come in protective packaging with the Mi logo. Copies are divided into quality classes: High Copy (good quality, close to the original) and OEM (base quality, often with less bright backlight and worse viewing angles. - For Redmi Note 6 Pro is characteristic IPS-resolution-matrix 2280×1080, A low-quality analog can significantly distort the picture.
⚠️ Warning: When buying a module, be sure to check the presence of a protective film on the frame and the absence of traces of glue. If the frame is plastic and wobbles, this is a sign of poor build quality, and such a module may not fit tightly into the case.
Also, some cheap modules may not have a built-in speaker or proximity sensor that you have to glue from the old screen, which adds to the complexity of repair, as it requires the use of thermophene and accuracy when working with microscopic components.
Tools and workplace preparation required
The success of the screen replacement operation on the Redmi Note 6 Pro is 50% pre-emptive. You don't need a professional engineer's desk, but a minimum set of tools is a must. The main enemy in disassembling is static electricity and dust, so the workplace must be clean, dry and well-lit. It's recommended to use an antistatic mat or just clean cotton fabric.
To carry out the work, you will need the following set of tools:
- 🔧 Sets of screwdrivers (cross Phillips #00 or #0 for screws of the body).
- 🔥 Thermophen or building hair dryer (to soften glue).
- 💳 Plastic card or mediator (to open the case).
- 🧲 Magnetic mat or organizer for screws (so as not to lose them).
- 🧴 Isopropyl alcohol and glue B-7000 (fixative).
Special attention should be paid to the heating of the case. The glue holding the back cover and screen melts at about 80-90 degrees Celsius. Overheating can damage the battery or plastic frame, so do not hold the hair dryer too long in one point. Movements should be circular and uniform around the perimeter of the device.
💡
Use the suction cup together with heating: suck it to the center of the back cover, slightly pull up, creating a gap, and immediately splash alcohol there or insert a plastic spatula.
The process of dismantling the old panel
Starting the dismantling of Xiaomi Redmi Note 6 Pro with device shutdown and retrieval SIM-Turn the phone down and heat the back cover around the perimeter for a while. 2-3 After heating, insert a plastic card or blade into the upper end, where there is usually a small gap, and carefully guide the tool along the faces, cutting the glue layer.
When you remove the back cover, you get access to the insides, and the first thing you do is turn off the battery to avoid short circuits, find the battery plume that goes to the motherboard, and gently disconnect it with a plastic blade, and then unscrew the screws that hold the protective plate over the display sockets, which are usually about 4-6 and they can be of different lengths, so it's important to remember their location.
☑️ Preparations for dismantling
And if you take the bar off, you get access to the display and touchscreen plumes, and you carefully unplug the connectors by pulling them up, not slapping them from side to side, and then you can move on to extracting the broken module, and you'll need to heat the front of the phone again, and you'll warm the screen up evenly, and then you can gently peel it around the perimeter.
⚠️ Attention: The backlight plume and main plume of the display are very thin. If the module is not carefully removed, they are easy to tear, which will make the new screen unworkable even with a working matrix.
Installation of a new display module
Before you install the new module in the Redmi Note 6 Pro, it is recommended to do a comparative analysis with the old one. Put them next to you and make sure that the location of the holes under the speaker, front camera and sensors matches. If you bought a module without a frame, you will have to move all the small elements: the speaker, the light sensor and the button plume. This is the most painstaking part of the work, requiring tweezers and magnifying glass.
The installation process begins with connecting the plumes to the motherboard. Make sure the connectors are up to click and sit straight. Then carefully frame the module, making sure that there are no plume clogs anywhere. Only after successful testing of the onset (you can temporarily plug the battery and press the power button) should you start the final fixation.
To stick the module and the back cover, use a special glue, such as a B-7000 or T-7000. Apply it with a thin strip around the perimeter, avoiding getting inside the body on the camera or speaker. After applying, press the screen and lock the device with rubber rings or a load for 15-20 minutes for primary polymerization.
What if the screen doesn’t work after replacement?
Comparison of cost and feasibility of repair
Before you start repairing it, it is worth assessing its economic feasibility. Xiaomi Redmi Note 6 Pro is not the newest model, and the cost of the original display can be a significant part of the market price of the used device. However, if the phone is dear to you as memory or works perfectly besides the screen, repair makes sense.
The table below compares the recovery options:
| Type of repair | Cost of spare parts (approximately) | Difficulty | Risks. |
|---|---|---|---|
| Glass replacement (GSA) | Low (500-800 rubles) | High (requires equipment) | High risk of breaking the matrix |
| Replacement of the module (Copy) | Average (1200-1500 rubles) | Medium | Worse color reproduction |
| Replacement of the module (Original) | High (2000-2500 rubles) | Medium | Minimum |
| Service centre | Part price + work | Absent. | Overpayment for work |
As you can see from the table, replacing the copy module on your own is a middle ground in terms of price and quality. Buying the original is justified if you are demanding on image quality. Repair in the service will add to the cost of another 50-80% of the price of the spare part, which can be economically disadvantageous for this model.
Typical errors and troubleshooting
Even experienced craftsmen sometimes make mistakes, let alone beginners. One of the most common problems when building a Redmi Note 6 Pro is getting dust under the new screen. Small villi or grains of sand left on the frame will create noticeable points or interfere with the tight fit of the glass. Before the final glue, be sure to blow the frame with compressed air or wipe with alcohol.
Another common mistake is to damage the plume when twisting the screws of the metal plate. If the screw does not fall into the hole or is twisted at an angle, it can push the plume, which will lead to the appearance of stripes on the screen. Always use dielectric tape or original insulation stickers on top of the plumes.
If you notice that the sensor is not working properly after assembly (patching taps, "phantom" clicks), this may indicate poor ground contact or damage to the digitizer during installation. In some cases, it helps to flash the device or calibrate the sensor through the engineering menu, available in the code # # # #6484#.
⚠️ Warning: Don't use superglue (cyanacrylate) to fix the screen! it highlights the pairs that settle on the camera and sensors, creating a whitish plaque, and also makes re-disassembly almost impossible without damaging the body.
💡
The main secret of success is not to rush when peeling off the old frame and thoroughly clean the surface before applying new glue.
Quality check and final assembly
Once the glue is grasped, you need to conduct a comprehensive health check Xiaomi Redmi Note 6 Pro. Turn on the device and carefully examine the screen for "broken" pixels, uneven backlight or yellow spots. Swipe your finger over the entire surface, checking the multi-touch. Make sure that the proximity sensor works (the screen goes out when you bring it to the ear).
Also check the front camera and the speaker, because when the screen is replaced, their plumes may have been affected. If all tests are successful, the repair can be considered complete.
Self-replacement is a skill that comes with experience, and the Redmi Note 6 Pro is a great training model thanks to its relatively simple design.
