Cleaning the imac 27 screen from dust. Cleaning the iMac matrix. Quality cleaning services from Yudu performers
After long-term use, each device must be cleaned from dust. It is better to perform this procedure in specialized service and repair centers. Such centers have everything you need: conditions, tools and qualified personnel. The cost of such a procedure varies within 3500 rubles.
The cleaning process can be conditionally divided into general cleaning from dust particles and cleaning of contaminants from the matrix. The important thing to know here is that the cleaning procedure will be slightly different for older iMacs. This is due to the fact that a display module has been used in thin monoblocks since 2012.
How often should iMac maintenance be done?
According to the information specified in the regulations, preventive cleaning of the monoblock should be carried out once or twice a year. This prophylaxis includes: removing dust particles from the inner surface of the case, radiators, fans, boards, changing thermal paste and lubricating the fans.
If the user notices that the monoblock case has begun to heat up more than usual, then it is worth taking the device for diagnostics in service center... Dust build-up can affect how hot your computer and its internals heat up during operation. You can independently identify the cleaning time using special utilities... If the fans are always running at full speed, and the case heats up almost immediately after starting, it is most likely to be cleaned.
Prevention at home
If you don't have extra cleaning supplies available at a service center, you can clean your iMac at home. This will take care. For older model, remove the front panel cover. Remove the strip protecting the RAM compartment and unscrew the screws from the bottom of the monoblock. An infrared port is located on the inside under the logo. Slide the screws securing the matrix ribbon cable and turn off the port. Remove the screen.
As such, the candy bar is ready for cleaning. Use compressed air. For this procedure, you can use a compressed air cylinder or a compressor (if you have access to it). For more complete removal unscrew all the retaining screws system board... This will lift the heatsinks and replace the thermal grease. Replacing it will have a positive effect on the operating temperature of the computer. After cleaning is complete, screw all parts in the opposite direction.
If we disassemble the newer Aimak versions (Unibody), there is no need to remove the product case. In such models, the screen rises. Use special suction cups for glass, if not, use a soft rubber plunger. Secure the glass with a plunger and pull, releasing the magnetic clips around the perimeter. Unscrew and remove the die. Disconnect the cables, carefully. The inner world of the iMac is open to us. We clean and change the thermal paste. Putting everything together in reverse order.
If you disassemble a thin iMac Slim or iMac Retina, the glass is also dismantled. For dismantling, a plunger is not required, the glass is connected to the matrix and is attached to the body with double-sided tape. Lift the display module carefully to avoid damage. Peel off the tape, disconnect the loops. To replace the thermal paste, unscrew the system board. Clean off any dirt deposits and reassemble the device in the opposite direction.
Cleaning the iMac Sensor
If you notice hazy spots on the iMac screen that were previously absent, most likely dust has settled on the matrix. This is a common problem with the late 2012 27-inch iMac. Dust usually settles on the bottom of the display. Remove the screen from the candy bar, peel off the tape and disassemble the display module. Disconnect anything that interferes with separating the display module into its components.
When all protective covers have been removed from the display module, turn the display glass side up. Separate the matrix and reflective layers. Set the matrix aside. Reflective layers must be held together with clamps. They will keep the reflective elements from shifting. After everything is fixed, wipe the dust from the surface of both the layers and the matrix. Cleaning must be done with a dry, lint-free cloth.
Assemble the display module by doing all the steps in the opposite direction. But before fully installing the display back, make sure that there is no dust or debris left on the matrix. Connect the screen to the device and turn it on. Check the entire display for debris, if nothing else, turn off your iMac. Next, complete complete installation module into the body of the monoblock. Disassembly of the monoblock must take place under special conditions. Use a soft cloth or towel to lay the display. This is to prevent accidental scratches or damage.
The humidity of the room is of great importance. The higher the humidity, the easier the dust particles will be removed. Use a humidifier. When handling the matrix, avoid handling it with your hands. Better take her over the edge. The fewer prints you leave, the fewer greasy marks you have to wipe off. If you doubt your abilities, do not disassemble the iMac yourself for prevention, so that it does not happen that you disassembled the product, but could not assemble it. Better contact a specialist at an authorized service center.
Without experience, it is almost impossible to clean the display properly. There is a high risk of damaging thin plumes or bringing dust into the multi-layered “cake” of the backlight. After service from a non-professional, the result is usually the following: the display is crooked and hardly fits into the case, scratches and fingerprints are visible on the surface of the matrix, dark dots (grains of dust) are visible on the white background of the display. Remains of unremoved aluminum tape dangle on the display and can fly away along the case and short-circuit something on the board. A loosely assembled display will pick up the same amount of dust in six months.
From 3500 to 6500 rubles. The price is determined by the model and diagonal of the iMac or monitor. On latest models iMac, you need to peel off the display from the case for subsequent disassembly. During the assembly phase, the display module is glued back onto the original set of tape.
Cleaning your iMac at home is not possible due to special conditions... Disassembling an aimag or a monitor will not be difficult for a master, but to assemble it so that after the main cleaning at the assembly stage a speck of dust or a speck does not fly in, you will need a comfortable table and a room with clean air. As practice shows, 90% of displays already cleaned by someone come to us with dark dots, like dead pixels, this is the same rubbish left after cleaning by non-professionals. Mac Service recommends! Be sure to negotiate the result when you give something, and something for repair. For example, if we clean the iMac's sensor, it means it will be as good as new. For reference, one or more broken pixels are a reason to replace the display by Apple guarantees, which means that such a defect is in principle unacceptable, like a dusty screen. If you have the matrix cleaned, do not rush to calculate, turn on the screen with a white background on your desktop and carefully examine the entire area. If there are dark spots, specks and specks of dust, feel free to make a claim!
The display module installed in all iMacs and Cinema / Thunderbolt monitors is poorly sealed, as evidenced by gaps and gaps between the sensor and the metal frame, as well as in other parts of the display. One small gap is enough for a dark formation on the matrix to appear within a few months. Accelerates the dusting process, operation in the same room with a working ultrasonic humidifier. In our service, the display sealing elements are replaced and the gaps are glued, which eliminates the appearance of dust spots for many years.
Disassemble Apple display without experience, extremely risky: removing the metal frame from the display requires skill in order not to damage a large thin glass(the matrix itself) and wide thin loops. At the assembly stage, coarse dust may get between the backlight and the matrix, then the structure will have to be disassembled again. However, the older iMac and Cinema / Thunderbolt models have optical drive(until 2012), it is possible to easily remove the glass using two suction cups, it is held on magnets. This gives access to the inner surface of the glass. Using microfiber and a monitor cleaner can remove grime and dirt, if present.
How to clean the monitor matrix?
The master's answer:
It would seem that you can't imagine a simpler task, what's the big deal? But you also need to be able to properly clean the monitor in order for it to serve longer. Moreover, and at the same time not to harm him or not at all to break it irrevocably.
For cleaning, you will need a special tissue or some kind of monitor spray. Properties such as neatness and care can also come in handy to avoid damage to the monitor or partial damage to it.
First, choose a napkin. Here, when choosing, you need to take into account the type of your monitor, as well as the type of matrix installed in it, since the wipes are impregnated with a special liquid. An improperly selected cloth can negatively affect the matrix of your monitor. You can first search the Internet for what wipes are suitable for the device, or ask the seller about it.
If you are the owner of a glossy monitor, then you should not choose heavily soaked wipes, as they will leave ugly marks and stains on the surface, and this is very noticeable on gloss. It is best to buy lint-free wipes as they will not leave any marks on your monitor at all.
Unplug the monitor before cleaning. Next, remove all dust from the monitor with the first cloth by wiping it thoroughly. If there are marks in the form of stains and streaks, then remove them with a second napkin. When cleaning, do not put pressure on the monitor matrix, as it is made of a rather fragile material that can break faster under pressure than you think.
If you are the owner of an ordinary monitor, then you can safely clean it with any lint-free cloth and any cleaning liquid, since such monitors are quite strong. safety glass, then you don't have to worry about the pressure, it will withstand it even with a margin.
Next, it is worth turning the monitor over with the matrix to the floor so that the cleaning liquid does not get under it, which will leave ugly marks in the form of stains. You should not use various industrial products, such as window cleaners, powders, etc. This can damage the matrix. If there are no special products, it is better to use a simple cloth, there will be no harm from it.
In general, the main thing when cleaning the monitor is to be careful and careful, then cleaning will not bring you any problems. Moreover, it will extend the life of your monitor with more or less respect for it. As a result, your monitor will be able to serve you for many years.
In order for any device, from a vacuum cleaner to a computer, to serve for a long time, it needs timely and accurate care. Not everything can be done with your own hands. For example, there is such a delicate procedure as cleaning the matrix from soot and dust, which it is better not to carry out with improvised means. The advantages of performing this procedure in a workshop are as follows:
Faster and more reliable
Since it is not a problem for experienced professionals to clean the iMac matrix from soot of all models and years of production, the mechanism for its implementation is perfected to perfection. Therefore, what would take you a lot of time at home is carried out in the workshop quickly, efficiently and without the risk of breaking any desired train.
The quality of the result is higher
In order not to doubt how high-quality the cleaning of the aimag matrix from dust will be, whether all the necessary parts will be cleaned of contamination (after all, it can be not only dust, but also soot, other contaminants), and whether this will damage the insides of the computer, it is better to contact to those who thoroughly know the intricacies of iMac care.
Get a clean computer in an hour
To carry out preventive cleaning of the aimag matrix from dust, you can order a courier or take the computer to the workshop yourself, and it will be clean very quickly, and you can pick it up yourself at any time convenient for you or receive it by courier.
Good day! How much does it cost to clean your imac 27?
Hello, 9,000 rubles.
Good evening. How much does it cost to clean the imac 21.5 sensor from hooves and dust?
Hello, 8,000 rubles.
Good afternoon, can you clean the matrix from soot and dust for new models?
Hello Sergey. The latest iMacs don't have this problem. This defect of the matrix is observed only in models of 2009 - 2012 (with a DVD drive)
Hello! I have an iMac 27 late 2012, new type - thin. In the lower corners of the display, spots of either micro-dust or soot are slowly growing - I don't know. Looks like small smoke marks. I read that this is a recognized marriage in the first batches of thin models - they were changed under warranty. But my warranty is over, and I have these questions: 1. Because. the glass is soldered to the matrix, you probably have to change the entire matrix ?? Or is cleaning possible contrary to popular belief? 2. If cleaning is possible, will the stains reappear over time? How much does this cleaning cost? 3. If cleaning is still impossible - how much does it cost to change the matrix + glass? 4. If changed, will there be a warranty for the new display and what?
Hello Kirill. In your case, it is easy to clean the matrix from dust and soot. You don't have to change the entire matrix. Spots on the matrix may reappear over time; for this, for prevention purposes, cleaning should be done 1-2 times a year. Cleaning the matrix on your device costs 12,000 rubles. Contact our service center and we will always be happy to help you.
In which we talk about how to fix certain problems with Apple computers. MacFix is frequently visited by desktop users Apple iMac, production years from 2009 to 2012 inclusive, with the problem of dust on the screen.
In this article, we will explain and show you how to clean the matrices in your iMac 21.5 or 27 yourself.
Let's take a 2010 iMac 27 ″ for experiment. iMac (by appearance) was in a dusty room, even when turned off, gray stains are visible under the glass. And, as it turned out later, in this room they also regularly smoked, and obviously not thin cigarettes.
Before proceeding with the disassembly of the screen, you need to carefully prepare the work surface. The surface should be horizontally flat, clean, free of debris, and even more so without any crumbs. You can put a clean, dry and soft towel of a suitable size on the table (larger than the screen size - at least 10 cm on each side).
There should be enough space on the desktop so that during disassembly all the parts of the matrix in the disassembled state can freely fit on it. The bezels of the screen can also be removed under the table, if it is convenient. Let's get started.
The photo clearly shows (without removing the glass) that along the top of the screen there is a wide strip of dirt and dust.
Carefully remove the protective glass by grasping the middle of the screen with a suction cup.
With the help of visual inspection, we carefully study the state of the matrix and glass. The conclusion is unambiguous - wiping the glass and matrix with a cloth will lead nowhere. It is possible that only stains will remain from brushing off the top layer of dust.
We put the glass aside, remove the matrix and proceed to disassemble it.
The first step is to carefully remove all the trains.
We carefully memorize the position of the fastening frames attached on the short sides (magnets on top and on the vertical sides of the matrix, directed outward). We unscrew all the screws holding the frames to the base of the screen. Of all the screws, only two are short (remember the side on which they were installed).
The frames are in some places glued to the foil along the base of the matrix, therefore, to remove them, we use thin but durable tools (for example, a construction trowel and a specially sharpened spatula).
Along the upper border of the screen along the edge there are thin loops bent to the base of the decoder. They are not securely attached to the decoder. Therefore, any contact with them must be extremely careful. Even if you apply a slight force, the loop or even one contact on the loop may move away from the decoder's contact pad, or a crack from bending may appear at the base of the loop. In this case, the repair of the matrix can be considered complete. The new matrix on the 27 ″ iMac starts at 20,000 rubles.
Remove the aluminum adhesive tape around the perimeter of the entire matrix frame. This should be done slowly and very carefully! We will also have to remove the adhesive tape covering the decoder cover (along the top edge of the screen). We remind you that the new matrix on the 27 ″ iMac costs from 20,000 rubles.
We unscrew the screws securing the decoder cover. Remove the cover and carefully disconnect the two adapter cables from the main matrix board. Carefully peel off the matrix boards from the matrix body. Again, it will not be superfluous to remind that the new matrix on the 27 ″ iMac is expensive.
Along the perimeter of the screen (again very carefully) we take it out of the fastening latches, slightly bending the edges of the frame. It is more convenient to do this operation together, placing the matrix on a short edge on a flat hard surface. Everyone has already understood the cost of the new matrix.
Next, we very carefully remove the LCD glass of the matrix (we no longer remind about the new matrix). You will have to carefully and as easily as possible toss the decoders in order to raise the LCD glass, holding them strictly by the middle of the long side, without twisting or jerking.
We lift the LCD glass of the matrix and put it aside so that the cables from the LCD glass to the decoders do not bend anywhere and lie freely.
Under the LCD matrix we see reflective layers, the one closest to us along the upper side is covered with a wide strip of gray-brown soot.
We can only remove this kind of dirt with active chemistry. V this case we took Mr. Muscle Professional (no ammonia). White paper towels (no color print) are ideal for controlling dirt removal and cleaning fluid residues. Textiles are not good here - just smear the dirt on the LCD glass.
We do all the operations for washing and wiping the reflective layers and the matrix carefully and quickly enough, since the detergent, dissolving the dirt in itself, begins to dry out. We installed a bright lamp next to the work table to see that there are no streaks on the reflective layer and on the matrix.
We clean all surfaces, starting with the reflective layer, which remained in the mount of the display module.
Now it's time to clean the LCD glass. We very carefully transfer the glass to a clean surface so that the decoders lie freely on the table surface without any bends. In this case, the glass itself should lie tightly on a strictly horizontal surface of the table. It is better to do this operation together so that the LCD glass does not move on the surface of the table when actively wiping it with a paper napkin.
We can see the result of cleaning the reflective layer and the matrix in the photographs.
