    Preparation

    Preparation before disassembling the Samsung Galaxy Tab 3 tablet (namely, this model will be given as an example below), includes reading this article to the end.

    Next, prepare the necessary tools (more on this in the next heading) and choose a convenient place to work. A free table is perfect, on which you need to place a couple of cups to collect small parts such as screws.

    Why disassembly is required

    Disassembling the device at home is recommended when replacing certain components that are not soldered into the boards and are not installed deep under the case.

    A great example of such a part is a rechargeable battery on devices without a removable back cover. For example, the battery life is already rather long and it’s time to replace it.

    In addition, the analysis of the device is carried out in order to clean it. And this means not only cleaning from dust, but also removing corrosion.

    As a result, this is at least cleaning from dust and corrosion, even if no components need to be replaced.

    What tools are needed

    You will need a few tools: a Phillips screwdriver, a special plastic “spatula” for prying off some components and the case, a small and thin plastic object that will fit between the case panels (this object must be plastic, since a thin metal object can scratch the case when the side latches, and soft plastic will not scratch the same plastic case).

    How to disassemble a Samsung tablet?

    It will be useful for any user to know how to disassemble a Samsung tablet in order to solve some problems with his own hands or just clean the device, speeding up its work.

    Before moving on to the main part of the article with the preparation and step-by-step process of disassembly, I want to warn you that I do not recommend doing this to people who are absolutely not versed in technology and have never disassembled anything.

    Firstly, for beginners it may fail, and as a result, the gadget may be damaged to such an extent that it cannot be repaired.

    Secondly, even with detailed instructions, it is easy to confuse any components or parts of the case by assembling or disassembling the device incorrectly.

    Thirdly, with careless actions, there is a small risk of getting yourself damaged. Therefore, if you doubt that you can disassemble the device properly, then contact the tablet repair service.

    A step-by-step process for disassembling a Galaxy Tab 3 tablet

    Step-by-step instructions on how to disassemble a Samsung Galaxy Tab 3 tablet:

    • Pry off the side case latches, which are located around the perimeter, using the thin plastic object mentioned above. Do this slowly and clockwise. Each latch that comes out of the groove will be indicated by a corresponding click. When all the side latches come out of the grooves, the lower part itself will move away from the case, as if it were a back cover. Take her off.
    • Under the removed back panel there will be a frame consisting of metal and plastic in places. It holds the entire body together and is secured with screws, so it must be unscrewed with a Phillips screwdriver. In this case, put all the same screws in one cup. When the entire frame is unscrewed, place the tablet face down, grasp the frame with the fingers of both hands, and slowly pull up at a right angle.
    • The main board is now visible as well as the battery. It is screwed on with either one screw or two. Unscrew it with a Phillips screwdriver and place the screws in a separate cup so as not to be confused with the previous ones.
    • Disconnect the unscrewed battery by hand.
    • Find a camera cable that looks the same as it did when assembled. Then take a plastic “spatula” and gently pull the camera out of its connector. Place the removed camera on a napkin and preferably sign it before that, so that during the subsequent assembly it does not confuse the components with each other.
    • Find the volume button cable, which is connected by the system bus with these buttons, and slowly pry it with a plastic “spatula”. Next, place the detail on the signed napkin.
    • The display cable is the largest, and it must be carefully pushed away from the body with the same “spatula”. First, draw it around the entire perimeter of the train (where possible to draw along the perimeter), and then pull it out and put it on a signed napkin.
    • Now pull out the LED, memory card slot and sim card slot (if any). Do this in the same way as in the previous paragraphs, gently prying with a plastic “spatula”.
    • Further, it all depends on the specific assembly of Galaxy Tab 3. If you can see that you can disconnect the charging cable, then do it. If this train is located deeply and is almost invisible, then do not touch it.
    • When all the cables are disconnected, you can remove the motherboard by unscrewing the 7 screws that hold it (3 screws on the top, 3 screws on the bottom and 1 screw on the side, in the opposite part from the battery). In some assemblies, the board generally rests on several grooves, which must be pried around the perimeter with a thin plastic object (the same one with which the back part was disconnected). When the entire board is detached, grasp it with both hands and slowly lift it up at a right angle.
    • All that remains is to unscrew the headphone jack, which is secured with two screws. Then place it on a separately signed napkin.
    • If you need to disassemble the display, then first heat it with a hot air gun, and then pry it around the entire perimeter with a plastic “spatula”. On this model, the LCD and the glass above it are not one piece, so you can separate one from the other.

    When assembling, I advise you to use the instructions in reverse: from end to beginning. Assembly is often more difficult and more painstaking than parsing, so be extremely careful.

    The main problems of the Samsung 2000w vacuum cleaner

    Vacuum cleaners are equipped with electric motors, which are prevented from overheating by the air passing through the filters. When filters become clogged, dust or foreign matter can enter the engine, and the engine can overheat and shut down. Prompt detection and elimination of problems will help keep the engine working for a long time.

    Among the main malfunctions faced by the owners of models of this type, there are:

    • Changing traction power. Appears due to mechanical damage to the hose and the places where the hose and tube are connected, as well as foreign objects stuck in the passage.
    • Worn out filters that have not been replaced for a long time Many models are equipped with a special sensor indicating clogging, but if it is absent, it is possible to understand that the filter requires replacement by the characteristic dull sound of the motor, as well as by a decrease in the suction power.
    • No power on power-up or intermittent loss of current. With such a malfunction, the sound of a working device becomes intermittent, you can smell burnt dust or wires, in extreme cases sparks and smoke will appear. Check the vacuum cleaner by connecting it to several sockets one by one, and if the situation is the same everywhere, the cause of the malfunction is under the housing. In the presence of sparks and short circuits, the device must be urgently disconnected from the network and handed over to a specialist.

    Features of disassembling the vacuum cleaner

    The first recommendation: if you have not previously dealt with the repair of such devices, perhaps the repair of your equipment should be entrusted to the masters. External filters can be removed and cleaned without problems, but the case itself can be disassembled and, moreover, not everyone can assemble it on their own.

    If you decide to make the repair yourself, you will need special tools such as flat and Phillips screwdrivers, pliers, and sandpaper. Record each step with a photo or video. this will help you in the future to correctly assemble the device without unnecessary or missing parts.

    Vacuum cleaner repair

    It is possible to repair the vacuum cleaner on your own only with minor damage. In other cases, you may need specific parts and tools, as well as experience with household appliances. If the problem is not found during disassembly or looks serious, we recommend that you contact a professional.

If you ask yourself this question, then your vacuum cleaner has ceased to perform its functions correctly, and you want to correct the situation yourself. From our article you will learn how to disassemble a vacuum cleaner, find a breakdown in it and put it back together.

    Vacuum cleaner prevention

    In order to avoid malfunctions during the operation of the device, when using it, you must adhere to simple rules:

    • External filters need to be checked and changed periodically. These are important parts to help keep the engine cool and prevent clogging.
    • Large and sharp objects can clog the hose and impair its permeability and damage it and internal mechanisms. Use manual methods to collect them.
    • If during the operation of the vacuum cleaner there is a burning smell, smoke, gusty vibration, the device should be immediately disconnected from the power supply and the external filters should be inspected and cleaned.

    Major malfunctions

    There are not many of them. As a rule, they are quite trivial, but when they occur, disassembly of the vacuum cleaner is required. You cannot do without it when diagnosing faults. The main reasons for the breakdown of the vacuum cleaner are the following:

    • failure of bearings;
    • wear of engine brushes;
    • engine failure;
    • malfunctions in the electronic system.

    Along with the above, there may be other deviations in the work, but they, as they say, lie on the surface. For example, a fuse has blown. In this case, it is enough to replace it with a new one, and the vacuum cleaner will work again.

    Getting ready for disassembly

    Before proceeding with the repair, you need to prepare everything for this. First of all, you need a toolkit. Nothing unusual is included in it: a set of screwdrivers, pliers, a set of heads, an awl, a small hammer. that will be enough. Additionally, you need to have WD-40 fluid, EP-2 or Litol.24 grease, a soldering iron and a clean rag. To ring out electrical circuits, you will need an ordinary tester.

    For those who are engaged in disassembly for the first time, it is advisable to have a camera with them. to record the disassembly sequence.

    Disassembly and repair stages

    Disassembling a vacuum cleaner is not as difficult as it might seem at first glance. First you need to unscrew the mounting bolts from the case.

    After that, it will be possible to remove the cover. Having disconnected the wires from the electronic board, we carefully separate the case from the controls. On this, the main part of the disassembly work can be considered completed. Next, we carefully take out the engine and carefully remove it from the plastic case in which it is placed.

    All work must be carried out without the use of brute force so as not to break fragile plastic parts.

    Dismantling the engine

    Since the main part of the vacuum cleaner’s malfunctions arises from the engine, it often has to be disassembled for repair.

    This process is not difficult and looks as follows. Using a thin screwdriver, carefully remove the impeller cover. As a result, access to the nut of its fastening opens. By unscrewing this nut, you need to remove the motor brushes and loosen the body tightening screws. It remains to carefully remove the anchor, and you can start removing the bearings. As a result of the work done at the workplace, you should get something like this picture (pictured).

    A readily available tool is usually sufficient to remove bearings, but sometimes a special puller is required. After disassembly, all parts are thoroughly cleaned of dust and dirt. Particular attention is paid to the bearing seating surfaces and the engine manifold.

    The impeller nut has a left-hand thread. Exceptions are encountered, but very rare.
