Replacement of the display on Xiaomi Redmi Note 6 Pro: detailed instructions with nuances

Xiaomi Redmi Note 6 Pro is a popular smartphone with reliable hardware, but its display is vulnerable to falls and bumps. If the screen appears cracks, broken pixels or sensor stopped responding, do not rush to carry the device into service: you can do the replacement yourself. In this article, a step-by-step analysis of the process, from choosing the original module to testing after repair.

The main challenge when replacing the screen with the Redmi Note 6 Pro is to properly unplug the plumes and carefully work with the adhesive layer. Many users make mistakes during the disassembly stage, which leads to damage to the flexible boards or sensor failure. We will analyze each step in detail, point out critical points that even experienced craftsmen ignore, and give recommendations for the choice of spare parts.

Important: If you've never taken a smartphone apart, practice on an old device or watch video disassembly.The Redmi Note 6 Pro has fragile body latches, and a wrong opening can break the mounts.

Preparing for replacement: tools and safety

Before you start, you'll need to assemble a full set of tools, and without the right tools, you'll risk damaging the plumes or leaving marks on the body.

• 🔧 Plastic blades (2-3 (a) - for the careful smearing of the hull and the disconnection of the plumes.
• ⚙️ Screwdriver T3 and T5 for screws of the back cover and attachment of the motherboard.
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic mat or organizer – so as not to lose small screws.
• 📱 Suction cups (2 pcs) - for removing the display module after warming up.
• 🧴 Isopropyl alcohol (90%+) — glue-cleaner.
• 🔋 New display module – original or quality analogue (more on this below).

Don't use metal blades, they scratch the body and can close contacts on the board, and avoid cheap Chinese kits: their screwdrivers often lick the screws.

⚠️ Warning: If you are working with the Redmi Note 6 Pro for warranty, replacing the display will void it, in which case you should contact the authorized Xiaomi service.

Before disassembling completely turn off the smartphone and remove the SIM- memory card. The battery is not necessary to disconnect, but if you are a beginner, it is better to turn off the board by removing the battery connector (instruction below).

Selection of the display module: original vs analogues

The quality of the new screen is not only the image, but also the sensor, avtobrightness and proximity sensor. There are three types of modules on the market for the Redmi Note 6 Pro:

For the Redmi Note 6 Pro, trusted suppliers:

• 🛒 AliExpress – Look for sellers with a 98%+ rating and module reviews (e.g. HSD or KDZ).
• 🏬 Local service centers – often sell leftovers from original parts.
• 🌍 Specialty stores (e.g. GSMMart, ETradesupply).

Before you buy, check if you have a glue layer (LOCA or OCA) in the package, if you don't, you'll have to buy it separately, and make sure that the module has a built-in sensor and backlight, some cheap options are sold without them.

⚠️ Warning: The Redmi Note 6 Pro has a AMOLED- touch-enabled display. If you see the phrase "glass only" in the module description, that's a hoax. It won't work!

💡

Before you buy the module, ask the seller to send photos of the plume connectors. On the original, they should be marked MI or Xiaomi.

The Xiaomi Redmi Note 6 Pro is a step-by-step disassembly

Now, to the most critical stage, follow the instructions in strict order, and skipping the steps could damage the board.

Step 1 Remove the back cover

Turn on the dryer and warm up the back cover around the perimeter for 2-3 minutes. Start at the bottom edge (where the charging connector is), because the glue is usually denser there. Temperature is no higher than 80°C so as not to damage the battery. After warming up, put the lid on with a plastic blade and carefully guide it around the perimeter. The latches are fragile - do not apply force!

Step 2. Shutting off the battery

When you take off the lid, you'll see the motherboard. First of all, unplug the battery connector (it's at the bottom, under black insulation). Use a plastic blade to plug the jack lock. Don't pull the wires!

Step 3: Withdrawal of the motherboard

Unscrew all the screws (there are 12 of them: 10 under the screwdriver T3 and 2 under the T5). Carefully raise the charge over the edge, it is attached to several latches. Don't pull too much: under the board are the plumes of the speaker and cameras.

Step 4: Disconnect the display module

Warm up the front of the smartphone (on the screen) for 3-4 minutes. Then glue the suction cups to the glass and pull up. If the module does not respond, warm up the glue again. After removing, clean the frame of the glue residue with isopropyl alcohol.

Installation of a new display and assembly

Before you install the new module, check it for performance. Connect the plume to the board (without screws) and temporarily assemble the smartphone. Turn it on and check:

• 📱 Image quality — are there any broken pixels, slashes, uneven backlights?
• 👆 Sensor operation – all areas of the screen must respond to touch.
• 🔦 Autobrightness - the light sensor must adjust the backlight correctly.
• 📞 Approximation Sensor - during the call the screen should go out.

If everything works, turn off your smartphone and start the final assembly:

1. Apply a new adhesive layer (LOCA or OCA) to the frame or back of the module. For LOCA, use a UV lamp for polymerization.
2. Carefully lay the display module, combining the connectors of the plumes.
3. Fix the plumes on the board (first the main display, then touch).
4. Set the motherboard in place and twist the screws (do not tug!).
5. Connect the battery and check the device again.
6. Close the back cover, warming up with a dryer for reliable fixation.

If the screen does not turn on after assembly or the sensor floats, check:

• The density of the plumes fit (sometimes it helps to lightly press the connector).
• Integrity of flexible boards (whether there are cracks or breaks).
• Correct battery connection (sometimes power does not come to the display).

💡

On the Redmi Note 6 Pro, the sensor plume and the display are combined into one connector, and if the touch doesn't work after the replacement, but the image is there, the problem is with the module itself, not the connection.

Common Mistakes and How to Avoid Them

Even experienced wizards sometimes make mistakes when replacing the screen with the Redmi Note 6 Pro. Here are the most common of them and ways to prevent:

Another common problem is the "moiré effect" after the display is replaced, which manifests itself as wavy divorces on the screen, and arises from:

• 🔄 Incorrect installation of adhesive layer (air bubbles).
• 📉 Low quality module (especially cheap counterparts).
• 🔥 Overheating on drying LOCA- glue.

If you have moire, try re-gluing the module, and if that doesn't work, the module is defective, and it needs to be replaced.

Testing after replacement: what to check

Once you've assembled the device, don't just check if the screen is on.

1. Visual inspection: Is there any scratches or chips on the new glass, is the module exactly adjacent to the body (there should be no gaps), is the same lighting at all corners (no dull spots).
2. Functional test: Check multi-touch (simultaneous touching in different zones); test gestures (swipes, double-touching); make sure that the autorotation (gyroscope) works.
3. Sensor check: Light sensor (auto-brightness), proximity sensor (whether the screen goes out when you call), fingerprint scanner (if it is built into the button).

Stress test:

• Run a graphically loaded application (such as a game) – there should be no artifacts.
• Call your smartphone – check the speaker and microphone.

If you find problems, take apart the device and check:

• The density of the plumes.
• Integrity of contacts on the board (sometimes oxidized).
• System settings (for example, disabled autobrightness in Settings → Display).

💡

For a deep screen diagnosis, use the Screen Test app (available on the Play Market) to show broken pixels, backlighting and color problems.

Replacement cost in service vs self-repair

If you doubt your abilities, compare the cost of self-repair and contacting the service:

Self-repair is more profitable if:

• 💰 You have a limited budget.
• 🛠️ I have experience with electronics.
• ⏳ We need to bring the smartphone back to life.

Please contact the service if:

• 🔧 No tools or skills.
• 📱 Guarantee device.
• ⚡ The problem is more complicated than replacing the screen (e.g., a board is damaged).

The average cost of replacing the display in the service for the Redmi Note 6 Pro is 4000-8000 ₽ (depending on the module), in Moscow and St. Petersburg prices are higher, in the regions - lower.
