Do-it-yourself tablet repair: what is needed to revive the device. Tablet won’t turn on - do it yourself tablet repair Tablet battery is dead

Modern life is filled with a huge number of technologically complex devices. They make our life easier and richer. However, in case of failure, a significant amount may be required to restore the gadget at a service center.

Asus tablets have a reputation for being reliable and fairly affordable gadgets. You can also purchase such devices on the Internet.

Before disassembling the tablet, it is necessary to diagnose the breakdown. Specialized forums will help in this matter. In most cases, breakdowns are similar.

Therefore, the proposed solutions to a specific problem are almost guaranteed to help you too.

Once the cause of the problem has been identified and there is a specific plan to eliminate it, you can proceed to disassembling the tablet.

Devices must be opened very carefully. Any plastic card is best suited for this (the use of screwdrivers or household knives is prohibited!).

There are cases when a breakdown occurs during the warranty period. Some owners mistakenly believe that their breakdown is not covered by the warranty and try to repair the tablet themselves.

This is mistake! You should begin self-repair only after warranty service has been officially denied to you.

A non-specialist can carry out only some repair measures. To do this you may need the following tools:

• a set of special screwdrivers;
• soldering iron;
• magnifying glass;
• tweezers;
• hairdryer with adjustable air temperature.

To help, you can use videos from popular video hosting sites. Find a video in which the tablet is the same as yours and follow all the steps according to the step-by-step instructions.

Modern electronics are incredibly compact. This means that you must be as careful and attentive as possible (not only during repairs, but during assembly/disassembly).

In the video below you will see how to replace the display yourself:

Mobile technologies have long been entrenched in modern society, and it is difficult to imagine a person’s life without a smartphone or tablet. However, sooner or later all equipment fails. There are a huge number of reasons for breakdowns and their types. In order not to send the gadget to a service center and not wait several days, you can repair the tablet yourself.

First steps

• The first type are those that can be seen with the naked eye: a broken touchscreen, a broken connector and a faulty speaker. This is all on the surface and can be easily diagnosed.
• But with the second it is much more difficult. After all, understanding why the device cannot be turned on or why the Wi-Fi adapter does not work is quite problematic. In such cases, you should use special programs that test different modules of your tablet and provide all the information about them, and also show whether they work or not.

Required Tools

After finding a breakdown and deciding to repair the tablet yourself, you need a small set of tools, such as:

• a set of small magnetic screwdrivers;
• tweezers;
• a special spatula or credit card, which is used to disassemble the case;
• thin double-sided tape;
• detailed manual or video instructions for assembling and disassembling your tablet model.

It is important to consider the brand of your device. Sometimes it is quite difficult to repair tablets. It's quite easy to fix Samsung with your own hands. There are many spare parts from this company sold on the market. Repairing a Lenovo tablet with your own hands is also not difficult. But it’s difficult to get spare parts from less popular companies. However, not all breakdowns can be repaired at home.

Major breakdowns

Here are the types of breakdowns that, with the proper approach, can be corrected at home:

1. Reflashing the tablet. It is needed if the software part of the device begins to work incorrectly: programs begin to freeze or even close arbitrarily. All tablets have a button or combination of buttons that, when pressed, performs a full factory reset. If this does not help, you need to go to the official website of the device manufacturer and find your model, then download the latest firmware version in .zip, .rar, .7zip format. Next, you should launch a special program that will automatically begin updating your device.
2. If your tablet loses power too quickly or does not charge correctly, you will need to replace the battery. To do this, you need to remove the back cover, carefully remove the battery, and then find out what model it is and what its capacity is. Having purchased the spare part you need from an electronics store, you need to place it in place of the old one using thin double-sided tape.

Screen breakdowns

In case of many breakdowns, it is possible to repair tablets yourself. The screen is usually the one that breaks most often. Manufacturers specifically make it so that replacing it does not cause any particular difficulties.

• A broken screen is a frequent breakdown, and the reason for it is a careless attitude towards the device. Constant shocks and frequent falls can lead to cracks on the screen, which will have an extremely negative impact on the appearance of the device, and can also affect the operation of the matrix and sensor. If the glass or sensor has been damaged and stopped responding to touch, and you want to repair the tablet yourself, you will have to do a rather difficult job of replacing the touchscreen. To do this, you need to find out the markings of your device and order a new matrix with glass for it, purchasing and installing a new touchscreen according to the video instructions for your device.

• Mechanical defects are usually caused by hitting a hard surface or accidentally dropping the device. As a rule, in such cases, only the tablet body suffers, without affecting the entire electronic filling. Such unpleasant defects can be dealt with quite simply with the help of covers, stickers, stickers, etc., which are glued to the damaged parts. However, sometimes it happens that after a fall, the electronics inside the device fail, and then you won’t be able to repair the tablet yourself. You will need to seek the help of specialists.
• Problems with the touchscreen. This problem usually occurs when there is some kind of malfunction in the device or a software error. As practice shows, this problem disappears after flashing the device. This will only work if there is a problem in the logical part, and if there is a problem with the device itself, then the cause may be a disconnection of the touchscreen cable or motherboard. In this case, to resume work, you need to disconnect the front glass using a spatula and insert the matrix cable back.

Conclusion

It is highly not recommended to perform other types of repairs at home. Do-it-yourself tablet repair will be reasonable only for simple breakdowns. It is best to trust the repair or replacement of parts that are soldered to the system board to professionals from the service center, who will bring your device back to life at a reasonable price.

There are several reasons that you can eliminate on your own:

It's all about the operating system, you just need to press the power button and hold it there for 15 seconds, or press the RESET hole with a thin object and then try to turn it on.

Charger failure. Connect the charger to the tablet and try to turn it on; if that doesn’t work, try again after 10 minutes. Then wiggle the plug at the base of the tablet socket, it should move fairly freely, but if the plug doesn't stay in place, then you need to change the charger, and this is part of problem number 2.

2.The tablet is not charging

If the tablet works only with the help of a charger, then most likely the cause of the breakdown is in the charging, because it does not conduct enough power to charge the tablet, and its power is only enough to operate the equipment.

3. There is no image on the tablet

A fairly popular reason for the sudden disappearance of an image is the matrix. Try connecting your tablet to your TV using an HDMI cable. If there is a picture, then it is guaranteed that you either need to change the matrix or look at the cable connecting the matrix to the system board.

4. There is no sound on the tablet

If the tablet works properly, but there is no sound, then the reason is probably hidden in the device settings or in the headset jack.

First, check the settings in the sound menu, then move all the volume sliders to maximum, restart the tablet and check for sound. If there is still no sound, then the reason is most likely in the headset jack. And the connector is designed so that when you connect headphones, it switches the sound from the speakers to the headset. And two contacts in the connector are responsible for this; if they are shorted or broken, then perhaps the sound will disappear.
