If you notice that the sensor on your tablet has stopped functioning, do not rush to immediately take it in for repairs, since there is a possibility that the cause of this problem is of a software nature. Perform a Hard-Reset of the gadget system to return to the original settings. To do this you will need to do the following: press 2 buttons at the same time – « increase volume" and "home", then, without releasing these keys, press Power. You will see a message indicating that existing data entered by the user will be deleted. Hold down the Power key and restart the operating system.

The sensor and touchscreen on the tablet do not work
If your tablet's sensor is mechanically damaged and does not work (for example, after being dropped), the monitor may not show any signs of failure. But the touch screen will need to be changed. In this case, it is best to purchase a separate touch screen.
We also know that the display of tablet devices consists of a touch screen and, of course, a matrix. If the gadget was damaged after a powerful blow, then, most likely, you will need change both the display and the matrix. For products trademark You can buy these components separately from Apple, Samsung or Asus.
Coming to completion, it is necessary to first establish the cause of the non-working sensor, and this largely requires certain skills and knowledge from the owner.
How to change the sensor on a tablet device
First of all, having determined the reason for the damaged operation of the touch screen, you need to buy all the necessary components for replacement. Each manufacturer supplies elements and components in special sets: each element separately or in a three-in-one pack.
So, the procedure is as follows:
- Open the device by first removing the rubber plugs and screws.
- Take the screen and detach the sensor, which is traditionally attached to the display with adhesive. The operation is simple, since the touch screen is fixed with glue and you will need to use a slight temperature effect (approximately up to sixty degrees) for several minutes. The idea is simple: heated air is blown onto the display, but this is done carefully and carefully (make sure it doesn’t burst).
- Next, you need to lightly pry it with a thin handy object and peel it off from the monitor itself.
- Install the purchased sensor using glue or double-sided tape.
- Once you've assembled your tablet device, do a little display calibration using the dedicated software on operating system Andriod or Ois.
Note! If you don't already know, in every article I share useful information which I published earlier. I wrote about what to do if and I also said why. For gamers, I spoke on the computer and .
I will end here. I hope you understand what to do if the sensor on your tablet does not work. By the way, I want to publish a video of my performance soon. Do you think it's worth it? Are you interested in knowing about me? Write about it in the comments, and don’t forget to like the article. Peace and goodness to everyone!
Unlike desktop computers, functions and programs in tablets are controlled by lightly pressing the fingertip on the screen at the desired point. The tablet reacts to touch thanks to a thin transparent glass plate superimposed on the display screen. When you press on the glass (touchscreen), depending on the type of sensors, the resistance, inductance or capacitance of the mesh applied to the glass changes and thus the tablet receives instructions for a specific action.
The touch glass is very thin, but strong enough to break with your finger. But if the tablet is dropped on a hard surface or hit with a sharp object, then touch screen cracks, which is what happened with the glass of the children's MonsterPad tablet shown in the photograph.
Checking the tablet's functionality using the mouse
The image on the screen was uniform without defects or distortions. The tablet remained operational, since when you pressed the Power button, a window popped up with a menu to turn off the tablet, but it became impossible to control its operation by touching the screen with your finger.
For full check In order for the tablet to work, and the ability to turn it off before repair, it was necessary to connect a mouse to the Micro USB connector located on the side of the tablet. Mice usually have a connector for USB connections. Therefore, I had to buy a USB-Micro-USB adapter.
When you connect a mouse, the tablet system automatically detects it, and an arrow-shaped mouse cursor appears on the screen. Diagnostics showed that the tablet’s electronics are in good condition. Therefore, to repair the tablet, it is enough to replace the touchscreen with your own hands. After diagnostics, the tablet was turned off using the mouse.
While waiting to purchase a touchscreen, it is necessary to keep the tablet battery charged, since deep discharge sharply reduces the time battery life tablet.
Where can I buy a touchscreen for a tablet?
The search for a store to purchase a touchscreen for a children's tablet MonsterPad at a minimal cost led to the website of the time-tested Chinese online store AliExpress. The site presented a large assortment of sellers of touchscreens for the MonsterPad tablet.
The seller was selected a large number positive reviews and high ratings with an average price and free shipping. When choosing a touchscreen, pay attention to the presence of double-sided tape on it. If the screen is without adhesive tape, then replacing it will be complicated by the need to purchase such adhesive tape, cut it and secure it.
If you can’t find a touchscreen by the name of the tablet, you can try searching by its markings, which are usually applied to the flat cable running from the touchscreen.
The touchscreens of many tablet models are interchangeable. The main thing when choosing is to pay attention to the type of sensor and its diagonal size, expressed in inches. For example, the MonsterPad requires a 7" touchscreen.
The resulting parcel was a large, compared to the size of the touchscreen, polystyrene box completely wrapped in adhesive film. It is convenient to open such packaging by cutting the film with a knife along the line of connection of the box halves.
The touchscreen was removed from the packaging and carefully inspected for defects. Everything was in perfect condition. Trying on the glass on the tablet confirmed the size matches. To check its functionality, all that remains is to disassemble the tablet and connect the touchscreen to motherboard.
How to disassemble the MonsterPad children's tablet
Before starting to repair the tablet, to avoid scratches on its case and display and dust getting between the display and touch glass, you need to wipe the table with a damp cloth and cover its surface with a soft, lint-free cloth. The only tools you need are a knife and a couple of small screwdrivers with a Phillips and a flat blade. After preparing the workplace, you can begin repairs.
The MonsterPad children's tablet can be disassembled easily thanks to the screw fastening of the back cover. Using a sharp tool, remove the four plug legs glued with adhesive and unscrew the four screws using a Phillips screwdriver.
Then, even without the help of a plastic card, grab the case halves with your fingernails in the area where the tablet's power button and connectors are installed, and carefully move the halves apart. The power and volume buttons must be immediately removed and set aside so that they do not get lost or scratch the tablet screen if they fall under it.
The tablet has been disassembled sufficiently to begin replacing the touch glass. All that remains is to remove the cable coming from the touchscreen from the connector. In the photo the connector is in the far right corner.
If the tablet was disassembled to replace the battery, then its type is clearly visible in the photo. To replace the battery, you first need to unsolder the red and black wires coming from it from the motherboard and carefully remove it, overcoming the adhesion force of the double-sided tape.
To release the touchscreen cable, you need to use a screwdriver blade to move the clamps a couple of millimeters in the direction indicated by the red arrows in the photo. After this, the cable can be removed from the connector without effort.
How to check the touchscreen before installing it in a tablet
After removing the back cover from the tablet, it became possible to test the new touchscreen for functionality. To do this, without removing the protective film, you need to place a new touch screen on the broken one, carefully turn the tablet over, and observing the numbering of the cable, insert it into the connector on the motherboard and return the latches to their place. Then turn the tablet over with the display facing up and turn it on using the power button.
After downloading the software, you need to tap on any icon or just work a little on the tablet. If there is a reaction on the display when touching and scrolling through pages, then everything is in order and you can start replacing broken glass. Before starting the repair, you must turn off the tablet with the power button and disconnect the cable of the new touchscreen from the connector.
How to remove a cracked touchscreen
To remove a cracked touchscreen, use the end of a knife to pry it at any of the corners and try to lift it up.
In the MonsterPad tablet, the glass was glued weakly; there was no need to even heat the glued area with a hairdryer. The force of the fingers was enough to peel it off. The main thing is not to rush and perform this operation very slowly and smoothly.
Preparing the tablet frame and installing the touchscreen
After removing the cracked touchscreen, use a rag soaked in alcohol to degrease and remove any remaining adhesive from the frame.
Fortunately, the cracked glass did not crumble into pieces and there was no need to use a vacuum cleaner or hair dryer to blow off the small fragments. For the same reason, it is not recommended to scrape off glue residue with a tool.
To ensure that the cable did not interfere with the positioning of the touchscreen when gluing, a piece of polyvinyl chloride tube was inserted next to its release hole, as in the photo.
In the next step, the protective film was removed from the touchscreen from the applied adhesive layer to the edges.
All that remains is to tuck the cable into the hole in the tablet frame, rest the corner of the touchscreen near the cable into the notch of the frame and slowly attach it to the frame, controlling the accuracy of the placement in the opposite corner diagonally.
The touchscreen fit into the recess of the frame exactly, without gaps or displacement on the first try. There is no need to press the glass tightly at this stage of repair. It is advisable to do this after fully assembling and checking the operation of the tablet.
The cable is long enough, which is convenient for installation. However, to prevent the cable from breaking if it gets caught between the covers when they are closed, it must be folded in half and pressed a little, avoiding sharp bends.
All that remains is to install the pushers of the buttons for turning on the tablet and adjusting the sound volume and snap them into place back cover to the base of the tablet. Screw in the four self-tapping screws and install the removed plugs on them.
The independent repair of the tablet was successfully completed, it began to work and look like new, and the child can play his favorite games again. Now, I believe, he will be more careful with his tablet and other gadgets. I did not remove the protective outer film from the touch screen; let the owner of the tablet remove it and be the first to tap (touch) the surface of the screen.
I hope given step by step instructions will help any home handyman, even those without experience in repairing such devices, cope with the repair of a tablet or smartphone.
The cost of replacing the tablet's touch glass with your own hands was less than 10% of the original cost of the tablet.
A tablet is a device that allows you to access the Internet, call friends, play games, watch videos and listen to music. The gadget is very popular due to its compact size, light weight, fast Internet connection, accessibility and ease of use. Thus, a smartphone and a computer are combined in one device. Since the tablet is always in working order, it is not surprising that its components fail. Most often, tablet sensor failures occur. There may be several reasons: electronic failure, poor-quality software, mechanical damage. If it is necessary to entrust TV repairs in Kharkov, tablets and monitors, we recommend Solaris SC.
How to keep your tablet screen intact?
Modern tablets are light in weight and very thin, which means their screens are quite fragile. That's why you need to work with the gadget carefully. A slight fall will not crack the screen completely, but small cracks may appear and dust will begin to accumulate in them. In addition, the screen can crack due to temperature changes or excessive pressure. To keep your device intact, follow the following recommendations from experts:
- Do not carry your tablet in your bag without a protective case. It is better to give preference to rigid products;
- stick on the surface of the screen protective film and change it periodically. The service life of a good film is more than one year;
- do not leave the gadget on chairs, armchairs and sofas;
- Do not give it to people who have not previously used such a device; keep it away from small children and animals.
The screen is cracked, what should I do?
If the tablet could not be saved and it cracked when dropped, then there is no need to despair immediately. To begin with, experts recommend figuring out what exactly is broken and why the sensor does not respond to finger touches. The tablet screen consists of a matrix that transmits the image and a glass screen itself, which is also called a touchscreen. If only the glass screen is damaged, it can be easily repaired. You contact the workshop and the master will replace the glass with a new one. Such a service will not cost much. Follow the link to find out prices for tablet LCD screen repair in Kharkov. But if the matrix is damaged, then repairs will cost many times more.
Determining whether the matrix was damaged when the tablet was dropped is quite simple. If it is in working order, then a crack will be visible on the screen, but the gadget itself will continue to work normal mode. But there is a risk that over time the damaged glass will damage the matrix. This, although rare, does happen. In addition, the sensor is broken screen will not work correctly. That is why you should not delay your visit to service center.
Of course, replacing the matrix will be expensive. In many tablet models, the matrix and touchscreen are a non-separable unit, so both will have to be replaced. If the glass of the tablet did not break when dropped, but the touchscreen stopped working, then most likely the cable came loose and a microcrack appeared. In this case, you will need to disassemble the device and check the signal. If the screen responds to touch only in a certain area, then either the touchscreen or the module will need to be replaced. The appearance of spots on the display also indicates its damage.
Since gadgets tend to break down at the wrong time, many users try to fix them at home. We do not recommend doing this, since such an undertaking is not always crowned with success. At home, you can reboot the device, adjust the touchscreen, or clean the screen from dust. Please note that improper use of the touch screen may reduce the sensitivity of the touch screen. charger and low quality protective film. It is better to entrust repairs to specialists. In Kharkov, repair of monitor screens and tablets can be entrusted to the above-mentioned Solaris SC.

How much will it cost to replace the touchscreen on a tablet?
Parts for new models are much more expensive than for older gadgets. The average price of a touch screen is 800 - 2,000 rubles. In addition, many large manufacturers sell sensors in a set with a matrix, called a module (touchscreen + matrix). The cost of a matrix for a tablet varies from 1,500 rubles. Therefore, the price of such a kit is from 2,500 (the price of the touchscreen + the price of the matrix). In service centers, for replacing a matrix or touchscreen they charge from 500 rubles to 2,000, depending on the complexity of the work.
The tablet's touch screen consists of two parts: the touchscreen and the matrix. In most cases, the screen breaks, but the matrix remains intact. Therefore, even if the glass is cracked and the sensor is working, you should replace the screen as soon as possible. Don't delay repairing your gadget. Otherwise, you will have to spend money on not one part, but two. This, of course, will cost more.
All repair work on the gadget must be carried out very carefully so as not to completely damage the device.
Gluing the sensor takes a lot of time and effort. Before you start gluing the screen, you should make sure it is in good condition.
How to prevent your tablet's touch screen from getting damaged?

If you notice that the sensor on your tablet does not work, be sure to read our instructions. We will try to help you solve this problem.
Technology and electronics make our lives much easier every day. For the most part, we cannot live without tablets and phones, because almost all areas of our lives depend on them: social, economic, and sometimes even political. Therefore, when we discover that the sensor on the device does not work, it becomes very big problem, because there are practically no buttons for them, everything is controlled by a sensor.
Unfortunately, damage may sometimes not be visible to the naked eye. The reason why the sensor stops working is not always water/dust getting inside or careless handling.
So, what are the main reasons why the sensor on a tablet stops working:
1. Liquid or contamination has entered the sensor. This also includes contamination of the screen with fingerprints, which can lead to decreased or loss of touchscreen sensitivity.
In the first case, immediately after detecting liquid getting inside the tablet, turn it off and, if possible, disassemble it, clean it and let it dry. If stains appear on the screen that cannot be wiped off, then you should replace the screen and clean all internal components of the device to prevent oxidation.
2. Mechanical damage to the tablet (falls, shocks) or severe temperature changes. Even if the device screen does not have any visible defects, and the sensor still does not respond to touch, then most likely you will have to replace the touchscreen. If the sensor stops working due to exposure to too low or high temperatures, then best solution- wait, the malfunction should go away on its own.
3. Damage or detachment of the cable that is responsible for connecting to the touch coating.
4. Software glitch ( software) tablet.
The simplest thing that can be done in this situation is to restart the tablet and give it a rest for a while, since the gadget could “freeze” due to a large number of running applications, which led to malfunctions of the sensor. It is worth considering not only open applications, but also applications located in background, since they also load RAM.
If a simple reboot does not help and the sensor on the tablet still does not work, then you can try checking it for any viruses and removing all unnecessary or questionable applications. After these operations, you must reboot the device.
The next way to solve the problem with a non-working sensor is to reset the tablet to factory settings. Please note that in this case, all information stored on the device will be erased and cannot be restored. A device that has been reset to factory settings will be the same as it was on the day of purchase - crystal clear. Therefore, you should remove the flash drive and try to transfer all important files to a computer or other accessible device.
1. Soft reset.
Experts insist that regardless of the problem with the tablet, you should first perform a soft reset, and then, if unsuccessful, try to bring the device back to life using a hard reset.
A hard reset is carried out in two ways: through the “Settings” menu, the “Recovery and reset” submenu and through the “Recovery menu”, or “Recovery menu”. Since in the case of a sensor, control through the main menu is not possible, only the second method remains.
1. To enter this mode, you must turn off the tablet. Please note that the tablet must be fully charged, otherwise it may turn off at the wrong time and it will be more difficult to restore the system.
2. After the device turns off completely, you need to hold down a combination of several keys (power button and volume button) and hold until the following screen appears:
Photo: Recovery menu 3. You can navigate through the recovery menu using the volume key, and select items using the power button. You need to select “wipe data/recovery reset”.
Photo: Recovery menu 4. The next step is to agree to delete all data from the tablet by clicking on the “Yes – delete all user data” option.
Photo: Recovery menu 5. Now you need to proceed directly to reboot the system by selecting “Reboot system now”.
Photo: Recovery menu After a little thought (which may take a while), the tablet will perform all the necessary actions and begin to start.
Please note this method does not guarantee that the tablet's sensor will work. This is just one of the possible manipulations for his resurrection.
Photo: Touchscreen on tablet Another reason why a tablet's sensor isn't working or isn't working accurately (opening apps instead of just swiping through menus, tapping twice instead of once, etc.) could be that it's poorly calibrated (this applies to older devices with resistive displays). In order to calibrate the sensor, you must either use standard setting using Android OS services, or download calibration applications (for example, Touchscreen Calibration(Download)), or contact a service center when all other methods do not help.
All the tips offered above are not direct instructions to action. If you are not entirely sure that you can handle fixing the sensor on your tablet yourself, it is better to contact a service center, where experienced specialists will be able to determine exactly what the problem is and how to solve it.
