A broken smartphone screen is always an unpleasant surprise that can knock any owner out of the rut. Especially offensive when it comes to such a popular device as Xiaomi Redmi Note 7, known for its durable glass Corning Gorilla Glass 5. However, even the most reliable protection does not always save you from falling on a sharp stone or asphalt at an unfortunate angle. At this point, the user faces the main question: how much will it cost to restore the functionality of the gadget?
The cost of replacing a display module with a Redmi Note 7 comes from a few factors to consider when planning your budget. The parts market is full of different quality offerings, and the price can vary by many times depending on the option chosen. It is important to understand that the savings on components often lead to loss of brightness, sensor sensitivity, or even problems with fingerprint recognition.
In this article, we will take a closer look at the pricing of spare parts, explain the difference between original parts and analogues, and weigh the pros and cons of self-repair. You will learn why the original bezel display costs more, but is a better investment in the long run.
Factors Affecting the Final Cost of the Screen
The first thing that users encounter when looking for a spare part is a huge price range. Some services offer a replacement for 1500 rubles, others say the amount of 4000-5000 rubles. This difference is due to the type of matrix. There are original modules on the market that are manufactured in the same factories as the components for the factory assembly, their color reproduction, brightness margin and touch screen work fully correspond to the standard.
The second type is high-quality copies (High Copy) or so-called "factory" variants, which often lack Xiaomi's official packaging.They may cost less, but often have thicker bezels or less saturated colors.The cheapest segment is low-quality In-cell or OGS matrixes, which can quickly degrade, lose brightness or have "dead zones" around the edges of the screen.
⚠️ Warning: When buying a cheap display, you risk losing the automatic brightness control feature or getting image artifacts that will only be visible when the white background is turned on.
The price is also affected by the presence of a frame: a module assembled with a frame (Assembly with Frame) costs more, but its replacement is easier and more reliable. Cheap options come without a frame, which requires re-adhesive of the old case, the use of glue and the risk of damaging the plumes when sloppy assembly.
Price comparison: original, copy and pasting
Let's look at the specific price ranges that are relevant for the current period. Costs may fluctuate by region and currency, but the proportions remain the same. Below is a table that helps you navigate the approximate cost of components.
| Type of display | Approximate price (ruble) | Image quality | Resource of work |
|---|---|---|---|
| Original (Original) | 3500 - 5000 | Reference, IPS | High-pitched |
| Copy (High Copy) | 2000 - 3000 | Good, there's a possibility of distortion. | Medium. |
| Budget (In-Cell) | 1200 - 1800 | Low, faded colors | Low. |
| Glass pasting | 1500 - 2500 | Depends on the matrix. | Risky. |
If your Redmi Note 7 only has the exterior glass broken and the image and sensor work perfectly, the services can offer only glass replacements, which is cheaper than buying a new module, but the process requires factory equipment for separation and vacuum pasting.
The main risk of re-patching is the use of poor-quality glue or a violation of technology, which can lead to stains (“rainbow”) or detachment of the glass after a month of operation, and it is easy to damage the matrix itself when separation is made, and then repairs become meaningless.
💡
If you choose re-adjustment, be sure to ask the service whether they give a guarantee for tightness and absence of spots, and not only for the work of the touch screen.
Cost of work in the service center against self-replacement
When you decide to repair, you have to choose between handing over your phone to the master or trying to replace the screen with your own hands. The cost of work in an authorized or good private service is usually from 1000 to 2000 rubles on top of the cost of the spare part. What do you get for this money? Professional diagnostics, availability of tools, quality glue and, most importantly, a guarantee for the work done.
Self-replacement (DIY) saves you on work, but requires the purchase of tools: a hair dryer, suction cup, mediator, screwdriver and glue B-7000 or T-7000. For the Xiaomi Redmi Note 7, the process of replacing a module with a frame is relatively simple, but requires accuracy when connecting plumes.
- 🛠️ Tools: You will need special Torx screwdrivers and a plastic spatula to avoid scratching the case.
- ⏱️ Time: The experienced master takes a replacement 20-30 minutes, the newcomer can spend 1-2 hour.
- 🛡️ Warranty: The service gives a guarantee on the unit, when self-repairing you risk spoiling a new detail with inept actions.
If you don't have experience disassembling smartphones, it's best not to take risks. Incorrectly connecting the plume can short-circuit and fail the motherboard, which will cost significantly more to repair than the screen.
☑️ Checklist before the start of repairs
How to distinguish a quality display when buying
When ordering parts online or buying "radio parts" from a store, it's important to be able to visually assess the quality of the product. Original matrices have perfectly flat edges, high-quality sealing of plumes and markings. Cheap copies often show glue around the frames, and the plumes can be skewed.
Notice the thickness of the frames. In low-quality copies, the black frame around the image can be wider than the original, which makes the screen look smaller. Also important is the presence of an oleophobic coating. Swipe your finger across the screen: on good glass, your finger slides easily, on cheap glass, you feel friction.
⚠️ Warning: Never buy a display without checking. Turn on the module by connecting the plume to the phone (you can just attach it without gluing it), and check the touchscreen in all corners and the presence of broken pixels on a white background.
Another sign of poor quality is color reproduction: the image on cheap In-cell arrays often goes yellow or has an unnaturally cold hue that cannot be adjusted by settings.
The secret to checking the plume
Step-by-step instructions for replacing the module
If you're going to make a self-repair, you'll need patience and care.The process of replacing the display with a Redmi Note 7 Starts with turning off the device and removing it. SIM-Next, you need to warm the perimeter of the screen with a hair dryer or a heating pad to a temperature of about 80-90 degrees to soften the glue.
Using a suction cup and a mediator, carefully separate the broken screen from the body. Be careful: under the screen there is a plume of the fingerprint scanner, which can be easily torn, and after the battery is turned off, disconnect the plumes of the display and touch screen.
Sequence of action:
1. Warming up the edges of the hull.
Removal of the back cover (if changing without a frame) or the old module.
3. Battery shutdown.
4. Disconnect the display plumes.
5. Installation of a new module.
6. Check the work before the final assembly.The new module (if it is without a frame) requires careful cleaning of the old case from the glue residue and applying a new layer of adhesive. If you bought a module assembled with a frame, the task is simple: you just need to transfer the motherboard and battery to the new case.
💡
The most critical moment of replacement is to turn off the battery before working with the plumes, and ignoring this step can cause the power controller or the backlight to burn.
