Replacing the screen with Xiaomi Redmi 7: a detailed guide with photos and tips

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

The Xiaomi Redmi 7 screen is one of the most vulnerable parts of the smartphone. Falling from a height, a strong blow or even bad pressure in your pocket can lead to cracks, broken pixels or a complete failure of the display. If your touch module stopped responding to touch, and the matrix appeared slashes or vertical stripes, most likely, you can not do without replacing.

The cost of professional repairs in service centers varies from 3,000 to 7,000 rubles (depending on the type of screen and region). However, with patience and minimal skills, you can save up to 70% by performing the replacement yourself. In this article, we will discuss all the steps of the procedure, from the selection of spare parts to the final build, and also reveal the key nuance: why the original screens for Redmi 7 are often sold with deception and how to avoid it.

Before you start, evaluate your strength: repairs require care, as there are fragile plumes and small mounts inside the case. If you have not previously disassembled smartphones, practice on an old device or watch video disassembly, this will reduce the risk of damage to the motherboard.

What tools will be needed to replace the screen

Without the right tools, replacing the screen becomes an agonizing experience.

• 🔧 Plastic blades (2-3 pieces) - for careful slashing of the body and disconnecting of the plumes. Metal tools can scratch the frame.
• 🔨 Cross screwdriver (size) PH00 or PH0) — Using an inappropriate screwdriver will break the slats.
• 🔥 A hair dryer or a thermo-air station to soften the glue that the screen is glued to the frame. Heat temperature: 60-80°C.
• 🧲 Suction cup - helps to raise the screen after heating.
• 📏 Tweezers – for working with small details, for example, disconnecting the battery connector.
• 🧴 Isopropyl alcohol (90%+) — to clean the frame of the glue residues. Acetone or solvent cannot be used!
• 🔋 New glue tape (e.g., scotch, 3M 9448A) — screen-locking.

Additionally, we recommend buying an antistatic bracelet (costs ~200 rubles) to avoid damage to the chips by static electricity. If the bracelet is not available, regularly touch grounded metal surfaces (for example, a heating battery).

⚠️ Warning: Do not use a household hair dryer at maximum power - this can melt the plastic elements of the case.The optimal distance to the screen is 5-7 cm.

How to choose a screen for Xiaomi Redmi 7: original vs. copy

There are three types of screens in the Redmi 7 parts market:

1. Original (OEM) - taken from other devices or residues of factory batches, the quality is ideal, but the price is high (from 4,500 rubles), often sold under the guise of "original" repackaged copies.
2. Premium copies are made in the same factories as the originals, but with minor differences (for example, different glue or marking). Price: 2,500-3,500 rubles. Quality is close to the original.
3. Budget copies are cheap (from 1,200 rubles), often with the worst color reproduction, dim lighting and an inaccurate sensor.

How to distinguish the original from the fake when buying:

• 🔍 Check the serial number on the screen plume - the original it matches the number on the box.
• 📦 Original packaging must have a Xiaomi hologram and a print with a production date.
• 🎨 Copies often lack oleophobic coating (screen quickly covered with greasy traces).
• 🔦 Turn on the screen and check the uniformity of the backlight - on copies there are dark spots in the corners.

Where to buy the screen for Redmi 7:

• 🛒 AliExpress is cheap (risk of marriage 30-40%) and look for sellers with a rating above 98% and reviews with photos.
• 🏬 Local service centers – often sell originals or quality copies with a guarantee.
• 🌍 Foreign sites (e.g. Kimovil or eBay) – originals at prices below Russian.

Step-by-step: how to disassemble Xiaomi Redmi 7 and remove the old screen

Before disassembly it is necessary:

Turn off the phone and remove it. SIM-map|Charge the battery by 30-50% (full discharge interferes with diagnosis)|Make a backup of the data (in case of damage to the fee)|Prepare the workplace: clean desk, good lighting, screw containers-->

Now we're going to disassemble:

1. Heat the screen. Turn the dryer on at medium power and warm the screen evenly around the perimeter for 3-5 minutes. The glue should become elastic. Don't stay in one place for too long!
2. Push the body. With a suction cup, raise the screen at the bottom edge (where the charging connector is), insert the plastic blade into the gap, and slowly move it along the frame, separating the screen. If the glue does not respond, warm it up again.
3. Disconnect the plumes. Bend the screen carefully (don't tear it off completely!) and turn it off: 🔌 Battery plume (black connector) 📱 Display plume (white connector) 👆 Sensor plume (orange connector)

Use tweezers or plastic spatula to tweak connectors.

At this point, don't touch the motherboard or other components -- static electricity can damage them. If there's old glue left on the frame, remove it with alcohol and a napkin.

Installation of a new screen and assembly of the phone

Before installing the new screen, check:

• 🔍 Integrity of plumes (whether there are breaks or contaminations).
• 🧹 Clean connectors on the motherboard (clean with alcohol if necessary).
• 🔋 Battery status – if it swells, replace it before the screen is installed.

Follow the instructions:

1. Prepare the frame. Put new adhesive tape around the perimeter of the frame. Keep it open, it'll cause dust.
2. Connect the plumes: 📱 Display plume (white connector) 👆 Sensor plume (orange connector) 🔌 Battery plume (black connector)

Make sure the plugs are closed to the end.

Final check.

After assembly, turn on the phone and check:

• 🎨 Color rendering (whether yellow or blue).
• 👆 Sensitivity of the sensor in all corners.
• 🔦 Brightness and uniformity of lighting (are there any dark spots).

⚠️ Attention: If the screen flashes after replacement or pushes buttons spontaneously, check the density of the plumes.

💡

Before final assembly, take a picture of the location of the plumes and screws, which will help to avoid errors in the reverse installation.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when changing the screen.-5 Problems and ways to prevent them:

• 🔧 The screws are torn off, use a screwdriver strictly in size, and don't use excessive force, and if the screw is already torn, it can be removed with tweezers or a drill.
• 🔥 Overheating of the body. Keep the hair dryer at a distance of 5-7 cm and do not direct the flow of air to one point for longer than 10 seconds.°C.
• 🧲 Damage to plumes. Never pull the plumes, just gently lift the connectors. If the plume breaks, it can be replaced separately (cost) ~500 rubles).
• 🔋 Short circuit. Before connecting the battery, make sure all contacts are dry and clean.
• 📏 Imbalanced screen setting. If the screen is curved, the glue will eventually move away, and you'll have a backlash. Use the magnetic substrate to align exactly.

If the screen is not switched on after replacement:

1. Check the connection of the display plume (white connector).
2. Make sure the battery is connected and charged.
3. Connect the phone to the PC – if the computer sees it, the problem is in the screen or plume.
4. If the phone does not respond at all, the motherboard may be damaged (diagnosis is required in the service).

💡

90% of the problems after a screen change are due to improper connection of plumes or damage to contacts.

How much does it cost to replace the screen in the service and when to contact the professionals

If you are not confident in your abilities or faced with one of the following problems, it is better to contact the service center:

• 🔧 Damaged motherboard (for example, after a fall, the phone does not turn on at all).
• 🔋 Battery is up (self-replacement is dangerous!).
• 📡 Antenna plumes are severed (no network or Wi-Fi).
• 💧 The phone is in the water (complete disassembly and cleaning is required).

The cost of replacing the screen in services (for 2026):

Where to repair it:

• 🏢 Xiaomi service centers – a guarantee of 6-12 months, but the price is higher by 20-30%.
• 🔧 Local workshops are cheaper, but the quality depends on the master.

If you decide to repair yourself, but something went wrong, many services offer a service of “refinement after self-repair” (cost ~ 1000 rubles), which is cheaper than paying for a full replacement.
