How to fix a tablet if it won't turn on? How to repair a smartphone and tablet with your own hands: the main details of repair Good service centers for tablet repair

Topic of the article - The tablet does not turn on and repairing the tablet yourself. The reasons may vary. A number of reasons may be associated with the “iron” filling of the device. Also, the reasons may be hidden in an OS failure. Either way, users can take some steps to fix the problem themselves.

The tablet does not turn on - what to do?

It is important to remember the last time the tablet was charged. When completely discharged, sometimes ten minutes of charging is enough for the device to turn on. During charging, you should press the power button with short one-minute breaks so that the device turns on again. Of course, the charger must be in good working order.

If the charging option does not help solve the problem, then it is recommended to carefully inspect the tablet for mechanical damage. The presence of chips on the screen or dents on the case may indicate that the device has been dropped. In the end, the reason is obvious. If there are guarantees, you should go to a service center.

The tablet turns on and does not boot - what should I do?

In this case, the reason is hidden in the failure software. For example, the backlight may turn on, and then the inscription “ANDROID” or a picture of a non-working device appears. green robot. Here the reasons are as follows: incorrect installation of applications and forced termination system processes. As a result, she got hurt.

You can restore the device using the Hard-Reset or Hard-Reset program. By the way, the program can be found on the Internet. So, using Hard-Reset you can reset your tablet to factory settings. The principle of action in this case for most models, especially Chinese ones, remains unchanged:

You need to turn off the tablet.
Now you should remove the SIM card and micro card.
You need to hold down the volume up button for ten seconds - you can feel the tablet vibrating.
Using the volume and power buttons, you need to select the “Setting” settings in the menu, and then “Format System”.
Now you need to select “Reset Android”.
At this stage, the tablet will reboot.

This procedure will result in the data being erased. If it's clear how to flash a tablet, then you can repeat the procedure if it fails the first time. The caveat is that sometimes the result can be negative. In this case, it is recommended to think about completely flashing the device. On the website you can find information about how to flash Android with your own hands.

How to turn on the tablet without using the power button?

There are several reasons why the tablet's power button may not respond. However, the device can be turned on. In this case, you can turn on the device when it is completely discharged:

First you need to connect the charger.
You need to press the volume down and power buttons at the same time.
Using the volume down button, in the “bootloader” menu, select the “powder off device” section.
The option must be selected using the Power button.
After turning off the tablet, you need to disconnect the charger.
Now the tablet needs to be connected again - a charge indicator should appear on the screen.

Basically, that's all. If now the tablet does not turn on and does not want to charge, then you should check the charger and power supply. As for the power button, mechanical damage is also possible here. In this case, you should disassemble the device and restore the button (replace, restore paths, repair broken contacts, etc.).

In our age of technology, tablets are considered one of the most popular electronic devices, used by people of different ages. With their small dimensions, high parameters and autonomy, they can more than replace a desktop computer or laptop.
Therefore, it would not be bad to know their structure and how to troubleshoot minor problems without turning to specialists. Although there are now so many “specialists” with dubious reputations that no matter where you look, there are only masters. But in the end we end up with a tablet with even bigger problems, or we pay an exorbitant price to fix a trivial problem.
It's no secret that many don't even know how to remove back cover tablet, at least to assess the battery condition.
This article will describe a method for disassembling and repairing one of the tablets, but the principle and tools used do not differ much from the same operation with other devices.
So, we have before us a tablet whose screen does not light up when it is turned on after falling, although it makes startup sounds and pressing keys.
Externally, the touchscreen and screen matrix have no cracks or smudges. Let's try to remove the back cover.
For this, craftsmen use a mediator - a triangular plastic tool with sharpened corners. If there is none, then you can use the old one bank card or a piece of plastic ruler with sharpened and rounded corners. The photo shows that just such a homemade tool is used.

If everything is done correctly, it will not leave a trace of your intervention on the tablet body.
Under no circumstances use a screwdriver or anything metal for this purpose. The consequences will be disastrous, ranging from nicks and broken latches to damage to the cable, matrix and other “internals” of the device.
So, place the tablet on a previously prepared clean and flat surface, screen down. The surface could be a glossy magazine placed on a desk.
If it has a decorative cover covering the slots with SIM cards and memory cards, you should open it and move it to the side.

As for the cards themselves, they need to be removed. Otherwise, either they or the slots for their installation will be broken.
Next, we take our prepared ruler and try to insert its sharpened edge into the gap between the lid and the top part.
This must be done carefully without pressing hard. We simply follow the connection from one side to the other.

In order not to damage anything inside the tablet, when the mediator passes inside, you should hold it with your fingers 1-2 mm from the parts to be separated. Thus, when removing the cover, the fingers will act as a limiter.
We carefully move our tool around the perimeter of the tablet, without making rocking movements. You will hear the latches coming out of the hook one after another.
When the pick has passed around the circle and you can see that the cover has come loose, carefully remove it. Sometimes to do this, you need to move it down a little.

We remove the lid, and all the beauty of our pet’s inner world appears before us.

You can see the battery here, motherboard, cables, as well as other parts of the device.
The first thing you need to pay attention to is the battery. Does it have any swelling, leaks or other visible defects?
Next, disconnect the battery.

The fact is that after the fall one of the cables could have lost contact, so it is necessary to inspect them. It is strictly not recommended to do this with the battery connected.
Also, you should remember that static electricity on the human body can damage the electronics of the device, so at least periodically, before any actions with the board, touch the heating battery with your hand to remove the charge.
Most often, the battery is connected to a connector, so disconnecting it will not be difficult. Use a thin watch screwdriver or toothpick for this.

After the battery, disconnect the small plugs of the different sensors.

If they are nearby, it is better to take a photo of where and what happened.

Now the speaker plug.

Power, off and volume buttons.

Here pay attention to the connector itself. To pull out the cable, you first need to carefully lift the white part - this is the clip. When it is raised, the cable easily comes out of the connector.

It is when it falls that this part can either rise or break on one of the sides, then the contact of the cable disappears, which leads to various problems.
Therefore, sometimes it is enough to pull out the cable, insert it back and close the latch.
When the latch is raised, we pull out the cable using the same toothpick, namely its rounded shape.
Here is the photo of the screen cable. Basically it depends on it whether there is an image.

To get to the touchscreen cable, you will have to remove the speaker. It is secured with two screws.
Next, we do everything in reverse order. When inserting the cables into the connector, make sure that they go all the way in and only then lock them with a clamp.
Lastly, connect the battery.
Before putting the lid on, you need to check the operation of the tablet and only if everything is fine, close it. It's easy to do. Place the device on the same surface and apply the lid exactly around the perimeter. Then press evenly along the edge until you hear a characteristic click.
Very often, this repair procedure described above will return the tablet to its original working condition. This is certainly not a panacea, but it’s worth a try.

According to the latest statistics, the number of tablet computers sold is increasing every year. The reasons for this are very different: the balance between the dimensions and computing capabilities of the devices; absolute silence during operation, no additional components (keyboard and mouse); energy efficiency; high reliability due to the absence of moving parts. However, if there are no questions with the first points, then with the last it’s not so simple.

Now there is a huge number on the market inexpensive tablets from Chinese manufacturers, who are not too different high quality assembly, which sometimes leads to certain malfunctions. In some cases, it is impossible to do without contacting service centers, and sometimes it’s enough just to find information on how to fix a tablet at home and apply the knowledge gained in practice. Surprisingly, most often you can “lift” the device yourself, saving money and time. The main thing is to constantly remember that the answer to the question “can a tablet be repaired” is always affirmative, but without faith in yourself you shouldn’t even start.

Diagnostics

Any repair begins with identifying the fault. All of them can be divided into two categories: software, in which a “software” failure occurs for one reason or another, and hardware, when some internal electronic component fails. Depending on this, the approach to repair differs.

The likelihood of self-recovery is higher if we are talking about system error. Although in the first case you can fix the tablet. Broken screen- this is one of the most common breakdowns that can be fixed without outside help. To do this, you need to decide on the designation of the display, which is indicated on it, order a new one and replace it. Please note that models listed as compatible may not work in this configuration. Therefore, 100% coincidence in designation is desirable. If the tablet's operation is disrupted due to an update system files, obtaining root access rights, trying unsuccessful firmware, then it is definitely a software problem that can be solved by returning file system to its original state. This type of malfunction occurs most often. Let's look at how to fix a tablet if it doesn't turn on.

Preparation

In order to restore functionality tablet computer lost due to a software failure that resulted in the inability to download or any other similar troubles, you need to download the program to your computer Flash Tool. Actually, it should be familiar to anyone who has ever wondered “how to fix a tablet.” This application is designed to work with processors from MTK.

Next, we will talk specifically about tablet models based on such computing cores, since they are the most common. It is recommended to discard older versions of the program, since compatibility with new models may not be sufficiently ensured. It is worth paying attention to version 5.x.x. This software solution allows you to record internal memory device new system files, i.e. perform the so-called flashing.

System set

You also need to find and download the archive with the firmware to your computer. It is a set of system files, usually distributed in a single archive. It is important that it is intended specifically for the one being restored, including its revision.

It is best if the firmware is obtained from the device developer’s website. So, for example, for an Oysters tablet, you should not look for a suitable product on network resources from Apple, Lenovo, etc. Also, you should not ignore the possibility of finding the right one software solution on specialized forums, if for some reason the model is not supported on the official website. And finally, you need a cable that allows you to connect the tablet to your computer.

Definition of modification

It often happens that two outwardly completely identical devices are actually different. For example, a manufacturer, when assembling a new batch, may begin installing another type of display matrix into a tablet, similar in characteristics, but controlled by different drivers. Accordingly, two revisions of the same device will appear on sale, differing in the driver embedded in the firmware. Thus, anyone who wants to figure out how to fix a tablet simply must correctly determine the modification of the gadget.

If the system functionality is not completely lost, then this can be seen in the “About the phone - Build number” section. For example, in one case the version SA0001 is indicated there, and in the other SB0001. In such a situation, firmware from one device to another will not work. The modification is also indicated on the board, which is very useful if the device does not start at all.

Boot process for new system

The archive with the firmware must first be unpacked into a folder containing only Latin characters or numbers in the name. Then launch Flash Tool. In this program, select the scatter file and MTKxxx.bin, to indicate the paths to which a dialog will be displayed. The firmware mode must be set in Download. After this, you need to press the green button to start the process and connect the tablet to the computer. If everything is done correctly, the system will begin loading onto the internal media.

Nutrition

The case discussed above with loading new control programs is, so to speak, an ideal option. Although service centers even require an impressive reward for such work, there is nothing complicated about it, if, of course, the appropriate firmware is selected and the failure is software. But how to fix a tablet if it does not turn on due to a completely dead battery? In this case, any attempts to turn on the device are useless, and the connection charger leads to nothing. In fact, this is not a breakdown, but a feature of the operation, which also applies to smartphones, recorders, etc. The reason lies in the peculiarities of the charge controller, which controls the filling of the battery with energy.

How to fix a tablet that turns off and won't charge? Using a regular plastic card with sharpened edges, you need to disassemble the body of the gadget and get to the battery. It is usually connected to the main board with two wires through a controller unit. Most often these are black (“minus”) and red (“plus”) veins. You need to take any charging unit that produces the required voltage (current - preferably at least 1 A), and determine the polarity of the wires - often it is indicated directly on the case. Then unsolder both battery wires from the main board of the tablet and tape/solder them to the wires from the prepared charger, ensuring compliance. The block should heat up (up to 50 degrees) depending on the parameters. Upon completion, the controller will interrupt the process and the temperature will drop. The wires can be soldered back and the tablet can be assembled. If the problem was excessive discharge, the device will turn on and be fully operational.

How to fix a broken tablet

This is perhaps one of the most difficult breakdowns. If repair is advisable (the device is not broken into pieces), then you need to carefully inspect the damaged element and find a designation on it, which is a set of letters and numbers. Then, having this data in hand, order a replacement. Every character is important. In fact, there is nothing complicated about how to fix a tablet. One of the conditions for the successful completion of this operation is the correct selection of programs (in the case of a “software” malfunction), as well as the accurate determination of component models by designation numbers - if the failure is hardware.
