The upper part of the touchscreen does not work. HTC One XL sensor is partially not working

Modern gadgets have become an integral part of our life. The phone is the most common gadget. Almost every person has it. Unfortunately, even the most reliable phones can break due to shock, water or software glitches. The most common problem faced by many users mobile devices, - the sensor does not respond to touch. If the device is still under warranty, then you should immediately contact service center... Otherwise, do not rush, because there are times when the problem can be easily and quickly eliminated. The sensor does not respond to touch, what should I do in this case? Let's take a look at all aspects of this problem.

Phone screen repair

Before solving the problem, you need to make sure what is the reason for the breakdown of your display. This can be mechanical damage, liquid getting inside the device, or a software failure. If you are sure that you did not drop your phone or spill liquid on it, then we can assume that this is a software glitch.

Mobile phone screen cleaning

First, you can simply clean the display of your device. You will not harm the phone in any way, but you will improve the connection and perhaps the problem will be solved. This method can help if the sensor is not responding to touch. What to do?

We take a suitable cloth and liquid to clean the screen. Better to use a lint-free or any other natural fabric. To clean the display, we need a glasses or monitor cleaner.

If this method did not help, then it is worth moving on to the next steps. Of course, they may not help either. The true reason breakdowns can only be established by a professional, but he can not solve every problem.

A software glitch that caused the display to break

If the display of the mobile device reacts in places to your touches, then you can try to make a Hard Reset of the system, this full reset settings. But it's worth remembering that this can only help if the sensor is buggy from time to time. After a factory reset, install applications that can clean up the system registry. This will fix errors caused by rAM... Recommended apps are WinFixer and Cleaner4. Unfortunately, the second utility is paid, but it has good functionality. The first program is for you if you are not sure about the reason why the display does not respond well to touch, and you are not going to spend money.

All actions should be performed without a memory card. It may contain viruses that cause system malfunctions. After resetting the settings and cleaning the registry, you need to put the SD card in place and check the device with an antivirus. Select full device scan and wait. But even after the actions taken, the sensor does not respond to touch. What to do? In this case, it is necessary to proceed to replacing the sensor, since the cause was not caused by a software failure.

Mobile phone display replacement

The sensor does not respond to touch - what should I do? If the previous methods did not help, then it is necessary to replace the damaged display. Most often, this should be done when the device has fallen, cracked or moisture has entered. In the latter case, you may not even notice how liquid got into the phone, as this can happen due to temperature changes. Thus, the condensation that accumulates in the mobile device will interfere with the normal operation of the phone. At first, black spots may appear when working with the gadget, and later the sensor itself will stop responding to touches. In this case, you will need to change the screen.

Phone screen repair is not a very difficult process, the main thing is care and accuracy. Anyone can do this. The sensor does not respond to touch - what should I do? First you need to disassemble your device, but you should remember the sequence of actions so that in the future there will be no problems with the assembly. All plugs and latches can be removed with a thin object. You will need to carefully remove all elements from the latches with this object.

After disassembling your smartphone, you need to remove the display. It is necessary to check how the display is attached to the matrix. This can be done in two ways: monolithic or separate. This is very important, since when ordering a new screen, this aspect must be specified.

The sensor can also be connected to the PCB different ways... There is a contact method, while the sensor is simply disconnected, and wired. In the latter case, you should be very careful.

If you need to detach the matrix from the sensor, you must follow these recommendations:

First warm up the surface to 60 degrees. This can be done with a regular hair dryer. It should be heated evenly so that the glass does not crack and the glue heats up.
Next, you need to find a flat and thin object to easily disconnect the sensor from the matrix. To do this, simply pry off the edges and gently lift.

All that remains is to attach a new sensor. How to do it? The kit should include the sensor itself and the glue. First, we apply special glue, and then carefully attach the sensor.

New display cost

How much it costs Of course, the cost of the screen will differ for different models of smartphones. On average, to change the display on phones with a diagonal of 4.5 or 5 inches, you will need to pay about 700 rubles.

If you don't want to disassemble the phone yourself, you can contact a specialist. The master will ask for about 2,000 rubles. Although this procedure is not very complicated and you can change the screen yourself. Only this will need to be approached carefully and carefully.

Touch buttons do not work

The lower touch buttons are directly related to the screen and in case of their failure, it is necessary to do all the actions that we have already considered. If the touch buttons do not work, you should first do a full reset. Next, clear the system registry and check your device for viruses. Unfortunately, if the actions taken do not help, then you will need to change the screen.

Ergonomic touch devices arrived. What has changed with the new technology? Yes, almost everything related to management functionality. Therefore, a tricky situation when the sensor on the phone does not work requires immediate permission. Moreover, in some cases, the user has every chance to make repairs on his own. However, we read about this and many other things below.

Why did the sensor stop working?

There can be an incredible number of reasons. Despite the high manufacturability, in most cases, a fragile and rather "finicky" control element. The functional abilities of such a modern "miracle" are completely dependent on a variety of influencing factors:

weather conditions,
mechanical damage,
ingress of conductive liquid.

A software failure, spontaneous system failure can also be the culprit for the fact that the sensor on the phone does not work. Of course, all these shortcomings are conditional, because it plays the main role in the life of the used mobile device. Specifically, the performance of the device and its efficiency in operation depend on our actions.

Typical touchscreen faults

Mechanical damage most often results in various breakdowns. Falls and deformations are a kind of record holders of a widespread excuse: “I didn’t do anything, I just rode in a crowded minibus” ”or“ It’s not my fault that it’s so slippery ”. The consequences of a blow and excessive pressure on the apparatus can be different. From an innocent chip on the case lid to a spider-like pattern of a split display. The case may "tolerate", but the touchscreen and screen will need to be replaced. If the sensor on the phone does not work, you should pay special attention to the structural parts of the mobile phone. In the case when the body part of the device moves away from the touchscreen and you visually see the gap formed or find that it has shifted, you need to install the parts in place. Sometimes a smartphone loses its sensory performance due to a small amount of liquid trapped inside the gadget. And often you don't even know how the water gets into the bowels of the device. Although you should know that the condensate will pick up the most unfavorable moment in order to show its destructive abilities. Check the pads and connectors for oxidation. Physical defects: screen flickering, image distortion and other non-standard manifestations in the phone's operation may indicate that the device needs urgent repair. Delay and delay with professional help is not in your best interest ...

What You Can Do: Being on your own doesn't mean counterproductive.

If the sensor on the phone does not work well, first of all, calibrate the touchscreen. Usually this function is available in the main window of your device's settings. Such actions are carried out when the device is clearly working, when the body is intact, no traces of deformation or oxidation were found, and the sensor reflects the glare of light with an impeccably smooth surface. If the forecasts are not entirely rosy, you will have to transform into a mobile device repair engineer. Since the subsequent actions require certain skills and specific knowledge.

Oxide elimination and touch panel positioning

Arm yourself with a special (mobile) tool: Phillips and flathead screwdrivers, unnecessary plastic cards (bank or other type). Prepare rubbing alcohol, a clean toothbrush, eraser, and regular table napkins.

Finally

In case of a favorable outcome of all your manipulations, your touchscreen should work. If everything remains unchanged and the sensor on the phone also does not work, then only replacing this component of the control system will help you. What is not recommended at home. Therefore, you cannot avoid a visit to the workshop. Take care of your sensor!

A touchscreen phone is a very functional and convenient thing. However, the more high-tech the device is, the easier it is to damage it. The sensor (touchscreen) is the "Achilles' heel" of modern gadgets, because it is very fragile and at the same time is constantly exposed to mechanical stress. Sloppy users can put a bag on it, sit down, pour it, or even run it against the wall in a fit of anger. And now the long-suffering phone comes to a moment when the touchscreen sensor no longer responds to finger touches. What if the phone stops obeying its owner?

There are many reasons why the touchscreen does not respond to touch... The main provocateurs are hardware damage, which can only be diagnosed and eliminated at a service center.

What if you have the touchscreen does not work on the phone:

Pay attention to the tidiness of your phone first. Due to dirt or oil stains, the touchscreen may not respond correctly to the user's touch. Therefore, do not be lazy to regularly wipe the screen with a microfiber cloth. Such a simple cleaning can bring it into working order. In addition, make it a rule not to pick up your phone with dirty or wet hands.
An improperly installed screen protector can be the culprit for the touchscreen not responding to fingertips. This is due to air bubbles and dirt accumulated between the surface touch screen and a film. To solve the problem, you need to re-glue the film.
Sometimes the touchscreen does not work due to the fact that the signals received by the device may not be perceived correctly. In this case, a reboot or reset is enough to bring the system back to life.
Examine the screen carefully for cracks. Even small cracks can force. As a result, the touchscreen partially reacts to touch only in certain areas. Only replacing the sensor on the phone at the service center will help to return the phone to full functioning.
If the touchscreen does not work on your smartphone, this may be the result of a breakdown or failure of the sensor control chip. As a rule, failure of a microcircuit occurs due to shock and falls. It can also be caused by moisture penetration into the case. Replacing the microcircuit with a new one will help to solve the problem.
In addition to everything mentioned, part of the touchscreen on the phone does not work due to the breakdown of various components. For example, failure of the printed circuit board or its components, caused by moisture penetration, physical or mechanical stress, can lead to loss of functionality. Only a full-fledged diagnosis will help determine what exactly is out of order.

As practice shows, in cases where the sensor on the phone does not work, the problem lies in the touchscreen. According to statistics, in 90% of cases, replacing the glass on the phone will help to restore full functionality. And only 10% of the reason lies in other details.

Remember:

If the touchscreen does not work for you, do not try to repair the phone yourself so that you do not have to buy a new one later. Replacing the glass on the phone should be carried out only in a specialized service center using original parts, since fakes quickly become unusable and cannot be repaired.

The service center masters will promptly identify the site and qualitatively eliminate the malfunction at an affordable price.

Electronic components can break if used carelessly. If part of the touchscreen on the phone does not work, it may be caused as temperature regime use and mechanical damage.

Correct diagnostics will help to repair the screen of a smartphone or tablet that does not respond to touch. Sometimes simple cleaning, combined with disassembling the case, helps. However, if after all the user's actions the device does not turn on, it will have to be carried to the service, and this may lead to additional costs.

Breakdown reasons

There are the following reasons why a part of the screen does not work:

Oxidation of contacts due to the ingress of condensation. Moisture trapped inside the device can lead to complete or partial loss of functionality. Oxidized contacts stop responding to processor commands and transmit them to the screen. To eliminate the consequences of liquid ingress, it is necessary to disassemble the device and carry out cleaning internal components... To do this, you can use rubbing alcohol on a cotton swab or swab. After this procedure, the phone should turn on normally.
Cracks on the screen surface. Due to micro damage to the sensor, it stops responding to pressing. Such damage occurs due to falls or impacts on the screen. You can identify cracks on the display by carefully examining its surface. If part of the touchscreen is covered with cracks, then it is possible to return it to work by replacing the touchscreen of the device.
Disabling touchscreen contacts as a result of displacement. This usually results in the lower or upper half of the screen not working. To diagnose contact misalignment, you need to disassemble the device and see if the visual order of symmetry of the components is broken. If you see misaligned contacts, you can try to correct them using tweezers. In addition, some of the elements are fixed on glue, which can melt at high temperatures and displace the contact. In order for the upper part to return to its place, you need to heat the mount with a hair dryer and return the component to its original position.

Features of the operation of electronic devices

In addition to the listed breakdowns, electronic devices may malfunction due to internal architecture. The limitation of the size of the components affects their power reduction if the tablet screen does not respond to touch - this may be due to the overload of the device with a large number of resource-intensive applications. For prevention, you need to start the task manager. Find out what is loading the central processor of the device, and disable unnecessary applications.

Electronic devices have increased screen sensor sensitivity. The situation when the screen of a tablet or phone does not work may be associated with trivial pollution. Grease and dust sticking to the surface makes the tablet unresponsive to touch.

If the screen does not work on the tablet, the best solution would be to take it to a service center for diagnostics. Most models have a very long warranty, which will allow you to replace the device with another device without defects or get your money back at no additional cost. If the case is not guaranteed, perhaps you just need to buy a new gadget and then treat it more carefully.
