Modern smartphones like the Xiaomi Redmi Note 6 Pro have excellent specs, but their glass screens remain a vulnerability when falling.Cracks, black spots, or a complete inoperability of the touchscreen are a signal that it’s time to replace the module.Self-repair saves a significant amount if you’re willing to act carefully and consistently.
The process of replacing the display requires some preparation and understanding of the device of the smartphone. In this article, we will discuss in detail each step, from the selection of components to the final assembly. Properly completing all the steps ensures that your gadget will again be happy with a bright picture and responsive control.
Before you start disassembling, it's important to understand that the display module on this model is often glued to the frame, which complicates the process, because it requires careful separation of the glass from the case or re-sticking of new glass. In most cases, it is cheaper and more reliable to buy a module assembled with a frame, which will greatly simplify the task.
Diagnosis and selection of components
The first step is to pinpoint the type of malfunction, and if there's an image that doesn't respond, or if the screen is broken, but the touchscreen is working, which is a rare case, it changes the way we do the repair, but 90 percent of the time, when there's a mechanical failure, the entire prefabricated module, including the matrix, the touchscreen, and the frame, changes.
When choosing a part for the Redmi Note 6 Pro, it is critical to pay attention to the quality of the matrix. The market offers originals, high-quality copies (High Copy) and cheap counterparts. Cheap options often have poor viewing angles, low brightness and quickly fail. The original module for the Redmi Note 6 Pro is marked IPS LCD and a resolution of 2280×1080 pixels.
It is also worth checking the presence of a frame in the kit. Buying a module without a frame will require gluing old glass, which at home is almost impossible to do without special skills and equipment. The frame should be metal, corresponding to the original design, with the right holes under the speaker and plumes.
Don't forget to order the right toolkit in advance. You'll need special screwdrivers, suckers and mediators. Using the wrong tools can damage the internal components, so you don't need to save on tools.
Tools and workplace preparation required
Quality repairs are impossible without a properly organized workplace. The surface of the table should be clean, flat and well lit. Small screws are easily lost, so it is recommended to use a magnetic mat or containers with cells to sort the fastener by dismantling stages.
To work with Xiaomi Redmi Note 6 Pro, you will need the following set of tools:
- 🔧 Set of screwdrivers (cross-haired) PH000 and flat) for the screws of the shell.
- 🌡️ Thermophen or heating pad for softening the glue under the back cover.
- 💳 Plastic card or mediator for opening the case without scratches.
- 🧲 Tweezers and suckers for careful lifting of elements.
- 🧴 isopropyl alcohol and B-7000 glue (if the frame is not included).
Pay special attention to safety. Before starting any work, be sure to turn off your smartphone. Although the battery in this model is not removable without opening, accidental short circuit of the display connector with the battery connected can disable the power controller on the board.
☑️ Ready for repair
If you don't have any experience with electronics, it's recommended that you practice on old technology or watch video instructions for disassembling this particular model, and visually understanding the location of the plumes helps avoid fatal errors in the process.
The process of disassembling the smartphone body
Starting the disassembly with the tray extraction SIM-This is standard procedure, but it's necessary to access some hidden screws and prevent damage to the tray when heated.
The Redmi Note 6 Pro's back cover is glass and glued around the perimeter. To remove it, you need to heat the edges of the case to about 80-90 degrees. Use a thermophen, evenly warming the perimeter for 2-3 minutes. Don't hold the hair dryer at one point for too long so as not to damage the matrix from the inside.
⚠️ Warning: Excessive heating can cause the battery to bloat or deform plastic elements inside the enclosure.Control the temperature with your hand - the body must be hot but tolerant to touch.
After heating, insert a suction cup at the bottom of the back cover and gently pull up to create a gap. Insert a plastic mediator or an old plastic card into the resulting gap. Swipe the tool along the perimeter, cutting the glue layer. Be careful in the area of the camera module so that the plumes are not damaged.
When the lid is removed, you open up the insides, and the first thing you do is unscrew the screws that lock the plastic shield that covers the plumes and the battery, and they're usually around. 10-12 They can be of different lengths, so remember their location.
Disconnecting the battery and dismantling the old screen
When you take off the safety panel, you see the motherboard and the battery, and the most important thing you do at this point is to disconnect the battery plume from the motherboard, and this will power the device down and minimize the risks of further electronics.
Then you have to disconnect the display and touchscreen plumes, which are located next to the battery connector, use a plastic blade or nail to gently lift the connector locks, and never pull the plumes themselves, which will cause them to break.
Now you have to remove the camera module and the speaker if they're attached to the old frame. Depending on the type of module you buy (with or without a frame), the actions may differ. If you have a frame, just transfer all the components from the old frame to the new one. If you don't have a frame, the process is complicated by the need to peel off the glass.
To retrieve the old screen, if it's still stuck on the glue, apply heat around the perimeter of the front panel again. Carefully push the matrix with the mediator, trying not to press on the center where the matrix layer itself is. The old screen can be thrown away, so you can apply the force boldly, but without fanaticism, so as not to damage the frame.
What to do if the plume is broken?
Clean the frame of the old glue and dust residues. The surface must be perfectly clean before installing the new module, otherwise there may be bubbles or distortions.
Installation of a new display module
Before the final assembly, it is recommended to conduct a test connection. Connect the plumes of the new screen and battery to the board without fixing them permanently. Turn on the phone and check the matrix for broken pixels and the touch screen in all zones.
If the test is successful, turn off the phone and remove the protective film from the adhesive layer on the new frame. Carefully combine the module with the body and press tightly around the perimeter. Make sure the plumes are stacked correctly and not clamped with metal elements.
| Phase | Action. | Important detail |
|---|---|---|
| 1 | Preparation | Checking a new module before installation |
| 2 | Cleanup | Removing dust from frame and camera |
| 3 | Installation | Removal of protective film from glue |
| 4 | Fixation | Tight edges clamping |
Put the main camera module, speaker and vibrator in place, make sure the speaker grid is clean and the camera sits tightly in its nest, and tighten all the screws of the safety board, keeping order so that you don't break the thread.
💡
Use a toothbrush to clean the dynamic mesh of dust before final assembly - this will improve the sound of the conversational speaker.
Assembly and initial inspection
The final step is to install the back cover. If the new cover is not glue-free, apply a thin layer of special glue B-7000 or use double-sided tape. Avoid getting glue on the camera and connectors.
Put the back cover on and press it evenly around the perimeter, and you can use the rubber bands to get better at fixing them, stretching them across and along the body. 15-20 You can use the time to get the glue together.
Turn on your smartphone and do a full diagnostic. Check the proximity sensor, brightness, colors and multi-touch. You can use Android built-in tools to check the multi-touch, or download the app from the store.
⚠️ Warning: If the screen doesn't burn after assembly, but the phone vibrates when you call, don't rush to disassemble it again. 15-20 minutes - with a deep discharge, the indication may not be immediately.
Make sure the fingerprint sensor (if it's on the back cover or in the screen) works correctly. On the Redmi Note 6 Pro, the scanner is located on the back, so make sure you don't damage its plume when you build it.
💡
Quality assembly is determined not only by appearance, but also by the absence of creaks when compressing the body and tightness of joints.
Frequent problems and their solution
Even with a careful assembly, there can be nuances, such as "dead zones" of the touchscreen often associated with poor contact of the plume or defect of the spare part itself. If you notice such areas, try reconnecting the connector, cleaning its contacts with a stripe.
The appearance of yellow spots or uneven illumination may indicate excessive pressure on the matrix during assembly, in this case, it is worth loosening the screws of the frame or checking whether the debris fell under the screen.
If the phone stopped seeing SIM-After the map is repaired, check the antenna plume, it's easy to touch or it's not tightly pressed when it's disassembled.
