Introduction: when to replace the screen and whether to do it yourself

Xiaomi Redmi Note screen 8T — One of the most vulnerable parts of a smartphone: one unfortunate fall is enough to make the matrix cracks, broken pixels or the sensor no longer respond to touch. 80% In cases of damage to the display module requires a complete replacement, as modern AMOLED/IPS-The panels are not partially repairable, but before you take your phone to the service center, you need to assess whether you can do it yourself?

Replace the screen on the Redmi Note 8T will cost 2-3 times cheaper than in the service (the price of spare parts is from 2,500 to 5,000) ₽ It depends on the quality of the product, but requires accuracy and basic electronics skills, and the main risks are damage to the plumes, disconnection of the battery contacts or improper assembly, after which the phone will stop turning on. In this article, we’ll look at all the steps of replacement, from choosing a display to testing a new module, and uncover hidden nuances that are not mentioned in 90% of the instructions (for example, why a new screen might not work with the original glass).

Diagnostics of malfunction: how to make sure that the problem is in the display

Before ordering a new screen, make sure that the breakdown is not related to other components.

• 🔍 Cracks or squashes on the screen surface (even if the sensor is working).
• 🖥️ Black screen when backlighting is on (check if the notification indicator is on).
• 👆 A broken sensor (partially or completely) with the image displayed.
• 🌈 Image artifacts: broken pixels, stripes, flickering.
• 🔋 The screen flashes when pressing the body (symptom of a departing plume).

If the phone doesn't turn on at all, the problem could be the battery, the motherboard, or the power plume, to rule out these options:

1. Connect the Redmi Note 8T to charging – if a charging indicator appears, the problem is not the board.
2. Try turning on the phone with the button "Loud up + Power" (Fastboot mode). If the screen remains black, but the computer detects the device through adb devices, the display or its plume is to blame.

⚠️ Warning: If the screen responds to touch but the image is missing, check the brightness settings (Settings) → Display. → Sometimes the problem lies in the lost parameters after the fall.

Display module selection: original vs. copy, which is better for the Redmi Note 8T

In the market of spare parts for the Redmi Note 8T there are three types of displays:

For the Redmi Note 8T, it is critical to choose a module with the right plume connector - this model uses a 30-pin connector (unlike the Redmi Note 8 Pro, where the 40-pin is).

• 📦 With frame - simplifies installation, but may not match the color of the body.
• 🛠️ Without a frame – cheaper, but requires a careful transfer of the old frame.
• 🔧 With glue tape - mandatory for reliable fixation.

⚠️ Warning: If you buy a display with AliExpress, check reviews for the “moire effect” – cheap copies often suffer from wavy divorces when scrolling.

💡

Before buying, ask the seller for a photo of the back of the module – the original should be the Xiaomi logo and production date (for example, 2022.05).

Required tools: what you need to replace

To disassemble the Redmi Note 8T and replace the display, prepare the following set of tools:

• 🔧 Plastic blades (2-3 pieces) - to separate the screen from the body.
• 🔨 Screwdriver. T3 and T5 — frame-holder.
• 🧲 Magnetic mat or container – so as not to lose screws.
• 🔥 Hair dryer or thermo-air station - for softening the glue.
• 🧴 Isopropyl alcohol (90%+) — clean-up.
• 📏 Suction cups (2 pcs) - help to light up the screen.
• 🔌 Tweezers - to work with plumes.

We further recommend:

• 🛡️ Antistatic bracelet – protection against static electricity.
• 📸 Loop or macro lens – to check small details.
• 🔋 External battery (Power Bank) – to keep the phone charged while running.

If you don't have experience, buy a replacement display kit -- it already includes shoulder blades, suction cups and glue -- it costs about 500. ₽.

Step-by-step: how to disassemble the Redmi Note 8T and replace the screen

The process of replacing the display takes 1-2 hours. Follow the instructions carefully so as not to damage the plumes or flexible cables.

Step 1: Turn off and warm up your phone

Before disassembling completely turn off the Redmi Note 8T and remove the tray for SIM-Then warm up the edges of the screen with a hair dryer (temperature 60-70)°C) for 2-3 minutes to soften the glue. Keep the hair dryer 5-7 cm away so as not to overheat the battery.

Step 2: Separation of the display from the body

Attach the suction cups to the bottom of the screen and gently pull up. Put a plastic blade into the gap and slowly swipe it around the perimeter to separate the display. Don't put too much effort into it -- there are plumes inside!

Once the screen is separated, put it on the table with the display down (to avoid damaging the matrix) and disconnect the battery and sensor plumes from the motherboard. Use tweezers or a plastic spatula.

Step 3: Turning off the old display

Unscrew the 4 screws that hold the metal plate above the display plume (T3 screws). Carefully tuck the plume connector and remove it. If the glue is too sticky, drop some isopropyl alcohol.

Step 4: Install a new display

Move to the new module:

• 🔊 Speaker and microphone (stick to the screen frame).
• 📶 Antenna plume (if it is attached to the frame).
• 🔋 Notification LED (in some modules not included in the set).

Connect the new display plume to the motherboard and lock it with a metal plate. Before final assembly, check the health of the device:

1. Connect the phone to charge - a charging indicator should appear.
2. Turn on the device and check the sensor, colors, brightness.

Step 5: Assembly of the phone

Apply the new adhesive tape to the frame of the case or to the display itself (depending on the type of adhesive). Carefully align the screen with the body and press it starting at the top. Twirl all the screws and check if there are gaps.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when changing screens, and here are the most common ones and ways to prevent them:

• 🔌 Battery plume damage – always turn off the battery first to avoid short circuit.
• 🧲 Loss of screws – use a magnetic mat or tape to fix details.
• 🔥 Battery overheating – don’t point the hair dryer directly at the battery, only heat the edges of the screen.
• 🖼️ Bubbles under the screen - the cause is poor-quality glue or dust.
• 📵 Broken sensor – check if the touchscreen plume is connected (it is thinner than the display plume).

If the screen flickers or changes brightness on its own after assembly, the backlight plume is likely damaged, in which case you will have to re-disassemble the phone and replace the plume (cost is about 800). ₽).

⚠️ Note: If you are using a non-original display, you may need to calibrate the sensor after you have been replaced. download the Touchscreen Calibration app from Google Play and follow the instructions.

💡

The most common reason for a new screen to fail is the wrong plume connection. Always check the fixation of the connector before final assembly!

Firmware and configuration after replacement of the display

In most cases, after replacing the screen with the Redmi Note 8T, additional firmware is not required, however, if you installed a non-original module, the following problems may occur:

• 🎨 Incorrect color reproduction (excess of blue or green).
• 👆 Poor sensor sensitivity (you have to press harder).
• 🔄 Spontaneous touches ("ghost taps").

To address these problems:

1. Reset your phone settings to factory settings (Settings → About Phone → Reset settings).
2. Update the firmware to the latest version through Settings → System Update.
3. If the sensor is not working properly, install a custom core (e.g., FrancoKernel) or run the sensor module through Fastboot: fastboot flash touch panel.img fastboot reboot

To check the quality of the new screen, use test applications:

• Screen Test – Checking broken pixels.
• Touch Screen Test is a multi-touch test.
• Display Tester – analysis of color reproduction and brightness.

Replacement cost vs. self-repair: what is more profitable

The price of replacing the Redmi Note 8T display in service centers varies depending on the region and type of module:

Self-repair is more profitable by 30-50%, but has hidden costs:

• 🛠️ Buying tools (if they are not available) — ~1 000 ₽.
• 🔄 Risk of damaging other components (e.g. camera or microphone).
• ⏳ Loss of time – the first time a disassembly can take up to 3 hours.

If you're not sure about your skills, the best option is to buy a display yourself (for example, on AliExpress or in a proven parts store) and take it to the service. Many workshops charge only 1,000-1,500 for working with your spare parts. ₽.
