Stripe on the tablet screen what to do. What does the image of an android with an exclamation mark indicate? Stripes or dots appear on the screen of your Android smartphone or tablet

Adviсe

There are a number of problems that can arise with your tablet display. At the same time, its service life does not matter. There are even more reasons leading to unpleasant consequences. It happens that the tablet itself executes commands, not allowing the owner to use the device’s capabilities to the fullest. It happens that the sensor does not respond at all or the screen turns completely white or black. Let's take a step-by-step look at the reasons for this gadget's behavior.

In this case, the MID operating system is not of fundamental importance. The principle of fixing the problem does not change significantly. Also, the type of sensor does not really affect: regardless of whether it is resistive or capacitive, the principles will again remain the same. Although the reasons are different. For example, the resistor may simply fall apart.

First aid

Here is a list of the most common causes of this malfunction and options for solving them.

Dust is the main enemy of electronics

The most common reason explaining the failure of household appliances is hidden in the accumulation of dust. In our case, it also takes place, but in a different sense. Dust can easily get between the sensor and the glass. To clean it, you will have to disassemble the device. You need to wipe with a soft brush or microfiber, but it is best to wash off the dust with distilled water.

Water

You can sin on water if the tablet does not respond to touch - what should you do in this case? It can only be verified experimentally. You will need a hair dryer, a screwdriver and something sharp and thin. Carefully disassemble the device and look where the cable from the sensor goes. You need to remove the cable from the connector and dry it well.

Inadequate display response frightens users who ordered MID by mail. For example, when purchasing directly from China or other countries. When turned on, the gadget does not respond correctly to touch. This, of course, is not the case if you buy it in a store, because the sellers do the calibration themselves. However, if you ask for a gadget in an unopened package, you will stumble upon the same problem.

A new device must be calibrated in any case, even if it works adequately. True, Apple devices are exceptions. This will make it much easier for you to work in applications that use a keyboard or small controls. Calibration is very simple. In MID on Android, the option is located in the Display section of the main settings. In Windows RT, calibration is found in display personalization.

Immediate problems

You can’t break everything down into categories and positions. Let’s just look at the problems using specific examples.

When a tablet screen flickers, it is quite difficult to determine the cause. Let's look at how this happens. The first option is software, that is, you just need to update the firmware. It’s unlikely, although users often fixed the problem by adjusting the power application, sometimes the reason was in a specific energy saving profile.

The second option is hardware. Here it all again comes down to poor contact between the display cable and its connector. More precisely, this is something that can be checked. If the loop does not help, then you only need a specialist to diagnose and, as a rule, you will not achieve anything.

The fact is that the tablet screen also flickers in cases of low-quality capacitors. They must be made of silicon, but Chinese manufacturers often try to save money on this. Sometimes a group of capacitors is not completely soldered. You can solder them personally, although this happens extremely rarely.

Sometimes the tablet screen blinks directly in Chrome, the native one. The developers themselves do not react to this fact in any way, but the problem is resolved by reinstalling the application.

Flickering of the display on the tablet can in no way be associated with unstable operation of the processor or matrix. It is a myth.

Now let's figure out why stripes appear on the tablet screen. Everything is simple here, but the solution is expensive. Stripes appear if the chip, voltage connector or Wi-Fi module is in close proximity to the matrix. The conductors of the latter are constantly heated, which leads to their deformation. As a result, stripes appear on the tablet screen.

repair: replacing the matrix, moving or isolating heating elements;
come up with a heat sink and continue to use it.

With the first method everything is clear. They took it to a service center or reinstalled the display in person. What about the heat sink? You need to find an element that heats up and, at a minimum, glue a copper plate onto the thermal paste. It is best to move the element to the side if space allows and it is technically possible. The best thing to do is to prevent such a problem. You must understand: if the device gets hot, this is not normal. This is especially true for budget models. In the latter, you do not need to overclock the processor, but it is best to set a limit using the same overclocking programs. If the tablet is constantly heating up, then do not use a case, play heavy games intermittently and completely stop watching movies online. But this does not mean that the case is not needed at all. Thanks to the case, the tablet will last you much longer. Therefore, you should not completely abandon such an accessory, and if you still don’t have one, we recommend choosing the right one here.

You need to take a closer look at the charger if the tablet gets hot when charging. Replace it with another one with the same voltage but lower amperage. The gadget will take longer to charge, but will heat up noticeably less.

The tablet has a white screen

Well, now comes the fun part. The tablet has a white screen and does not respond to attempts to log in for a hard reset. Just a white screen. What to do? The whole problem is that the internal memory just disappeared. In most cases, a flash drive is no different from an external one, but is simply hidden under a technical tape inside, on the motherboard of the gadget.

You need to disassemble the tablet, remove it and format it on your computer. Important! The partition name cannot be changed; formatting must be done in FAT32. If the memory is not working at all, then buy a new flash drive and perform the same actions. Be careful! The flash drive should not exceed the volume of the previous one and have a class rating lower than fourth.

Next, you need to write firmware to it. It is advisable to do the same with an external flash drive. Sometimes the internal one simply does not connect to the firmware, but since you formatted it, the installation will start. You don’t have to do this, decide for yourself. Next, simply turn on the tablet. It may not work the first time; The firmware may not work. It is advisable to download the original version.

Although this is a little off topic, what to do if the pen on your tablet stops working. First, make sure the batteries in the pen are working. This does not apply to Wacom pens, which do not have batteries for this component. Also check to see if the tip has worn off.

Batteries leak very often. Replacing them alone will not help. Here you need to disassemble the component and clean the acid formations, although in most cases they need to be re-soldered.

There is also a problem associated with moisture getting on the contacts. Users themselves agree that coffee is often spilled on the pens or they themselves fall into the cup. It’s easy to dry, but it still doesn’t hurt to clean the contacts.

Non-hardware problems include driver failure or incorrect interaction. Repeated reinstallation does not always help; you need to experiment with their options. There are times when Photoshop or similar programs are incompatible with a specific pen. You need to download the program before connecting the pen or vice versa. Here you need to get used to it, since there is no clear solution to the problem.

I quote Alina:
Hello. It is necessary to disassemble and do visual diagnostics. Perhaps there is a hardware problem (that is, the screen “died” or some kind of cable broke). Maybe something else. Must watch. In addition, there may be a software problem. That is, the firmware itself is buggy. In this case, you need to disassemble the tablet, disconnect the battery to reboot it. After reboot, try to turn it on. If it turns on, then reset to factory settings -

A. What to do and how to treat?

Many users encounter a problem when phone or The Android tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

For example, the device has problems with defects of one kind or another in the image, color rendition, etc.. The reason for this may be:

1st: Software glitch- i.e. the problem is a software glitch

2nd: Hardware failure- i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)

However, do not rush to get upset - in 90% of cases there are problems operation of the system for adjusting color correction, detailing and other functions of the display smartphone a or Android tablet is to blame software glitch which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to "settings", find there "backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if after this the problem is not resolved, see Method 2.

Method 2.

Based on solving problems with communication and network reception phone number and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. The best tool to monitor system functions, corrects and corrects all possible settings and synchronization errors is an easy-to-use, free utility for Android devices. You can download the application from Google Play and see its additional options in the description. After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)
Method 3.

Changing the device software, or as it is also called "re firmware ". This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brings results, unfortunately, you will have to contact the Service Center for repairing your tablet a or smartphone a.

Stripes or dots appear on the screen of your Android smartphone or tablet. The display of a smartphone or tablet ripples, flickers, and blurs the image. What to do and how to treat?

What to do if stripes appear on the screen after the phone falls. Video guide from PC4USER.

If stripes or ripples appear on the tablet after an impact or fall, there is a possibility that the cable connecting the device’s motherboard and display has popped out of the connector. At the same time, the tablet itself is visually intact, there are no permanent black spots on the display or cracks. In this case, the device user can try to fix the problem themselves. To do this, you will need to carefully disassemble the tablet and insert the cable back into the socket on the system board.

In the event that you know that the tablet 100% did not fall, but the stripes still appeared on their own, you will probably have to take the tablet to a service center to replace the cable. Unfortunately, it tends to “wear out” over time.

Mechanical damage to the matrix

If ripples, stripes or spots on the display appear due to shocks, falls, and other physical influences, this may indicate damage to the matrix. This type of failure can be distinguished from the previous one by the presence of a crack under the touchscreen, or by the presence of dark spots of various sizes, which retain their constant position when the display is turned on. You can do independent repairs only if you have experience in replacing the display, and also have a new display in stock. Otherwise, you need to take the device to a workshop. Replacement costs vary depending on the tablet model and display size.

Video driver failure

Sometimes the reason for the inappropriate behavior of the image on the display may be caused by a software glitch. How to distinguish problems in the system from problems with the loop? If the tablet has not been subjected to mechanical stress, but the image changes color on its own, or duplication or overlaying of images occurs, try resetting the tablet to factory settings. If this does not work, you can try to reflash the tablet. And only if these manipulations do not solve the problem, can we assume that the culprit of the malfunction is the cable.

Cooling problem

Some budget tablets made in China may have problems with overheating and lack of cooling. The tablet may work quite normally, but after heavy load (for example, after playing games), it may freeze and streaks will appear on the display. After some time, the stripes disappear on their own and the tablet works again. Such symptoms clearly indicate poor-quality cooling, or even its absence. At home, you can organize a cooling system only if you have knowledge and skills in this area. In other words, may the service center help us.

Tablet screen flickering

The fact is that the tablet screen also flickers in cases low-quality capacitors. They must be made of silicon, but Chinese manufacturers often try to save money on this. Sometimes a group of capacitors is not completely soldered. You can solder them personally, although this happens extremely rarely.

A frightening situation - stripes appeared on the phone screen. But when using a mobile phone, no one is immune from this. And, it doesn’t matter how long you use this phone, the problem may arise immediately after purchase or after a few years. Let's take a closer look at why stripes may appear on your phone screen, and what to do about it.

Reasons for stripes appearing on the screen

The appearance of streaks can be due to a number of reasons that are inevitable when using a cell phone:

falls from a great height, impacts, pressure on the screen;
moisture ingress;
software failure;
viruses that can be downloaded and installed along with unverified applications;
overheating when charging;
manufacturing defects.

When using cheaply assembled phone models, any fall, shake, or blow can cause contact breakage, damage to the microcircuits and, as a result, stripes appear on the screen.

The stripes themselves can also tell you about the cause of the problem. If a black line appears on the screen after a fall, this indicates that the screen itself is damaged and needs to be replaced. If there is moisture or mechanical damage, multi-colored or white stripes may appear. Blue, yellow, green stripes indicate a possible software failure. The appearance of a red stripe indicates a manufacturing defect in the display; in this situation, it will most likely need to be replaced. Damage to the controller is indicated by the appearance of colored ripples on the screen.

What to do if stripes appear on the screen?

If, by all indications, the appearance of stripes on the screen is due to a software glitch, then at home you can reset to factory settings. If this does not help, then it is better to contact a service center, where specialists will reflash the phone and clean it of viruses.

In case of mechanical damage or moisture on the phone, it is better to immediately take the device to a repair shop, since repairing it yourself can aggravate the situation and make the repair more expensive.

The appearance of stripes on the screen is a fairly common occurrence. At the same time, the phone fully retains its functionality and the presence of stripes causes inconvenience when watching videos, reading, etc. #streaks appeared on the phone screen #stripe on the screen #red stripe #multi-colored stripes #blue stripe #white stripe #green stripe #yellow stripe #black stripe #why are there stripes on the phone screen #after a fall

You could leave everything as is and continue to use the phone, but if this breakdown is related to damage to the phone, then over time the problem may worsen and more expensive repairs will be needed. Therefore, if stripes appear on the screen, if you cannot cope with this at home, it is better to contact a specialist at a service center. In the service center, after diagnostics, the problem can be solved quickly and at a low cost.

Telephone is a very common problem. The main trouble is that such a malfunction can appear at any time: on the day of purchase or after several years of use.

However, despite the frequent occurrence of the problem, there are still device owners who do not know how to solve it.

What does the defect look like?

The main thing to remember is that the display does not lose functionality after a malfunction is detected. But this is not a reason to abandon the device in this state, because only its owner suffers from the incorrect functioning of the smartphone. If stripes appear on the phone screen, the image quality drops, so you will have to exclude reading and watching movies (few people like to “break their eyes”). That is, there will no longer be any point in having such a device.

The defect manifests itself as distortion of the content on the display. It ripples and runs in stripes (horizontal or vertical) of different colors: from black to iridescent tints.

Classification

Using this section, you can indirectly find out the cause of the breakdown, but it will be quite inaccurate. However, it's worth a try.

For example, colored and white stripes on a phone screen are often a sign of mechanical damage to some component of the display or a loose cable fit into the groove.
Black lines indicate the need to replace this part of the smartphone.
Colored ripples indicate a problem with the controller.

However, without opening the case, such “diagnosis” cannot be confirmed, so either your own hands or service centers can help.

How does the defect manifest itself?

This section is also important, as it will make it clear which part of the device (hardware or software) the fault relates to. Everything is quite simple here:

If stripes appear on the phone screen only when you launch a specific application or make any changes to the settings and files of the device, then the problem is a failure of the operating system.
When lines appear on the display after mechanical intervention, damage, or when touching the touchscreen, we can safely talk about problems in the hardware itself.

After determining the type of malfunction, you should move on to methods for solving it.

Line on the phone screen: what to do?

If the problem is caused by mechanical damage, then there are two ways: take the gadget to a service center or disassemble it yourself. In the latter case, you should look for a master class in video format that will show you how to open the case and get to the display. Next, you will need to carefully examine this part of the gadget to understand the extent of the damage.

If the problem is only that the cable does not fit tightly into the groove, then it is quite simple to correct it, and the stripes on the phone screen will disappear. But if it or the controller (chip) is damaged, there is nothing left but a complete replacement of components.

In the event of a software failure, the situation is usually corrected by a hard reset (resetting the settings, during which all personal data is deleted; it is recommended to save important files before performing it) or cleaning smartphones from viruses. Although the first method is more reliable, since many OS protection programs do not see the pest.

Reflashing the device also helps, but this step is best performed only by people with experience, otherwise the gadget will turn into a “brick” with a wave of the hand. Although this is also an option, then display malfunctions will be the least of your worries, but it’s not worth experimenting with.

Causes

Telephone problems arise in a number of situations, since a modern gadget is a very fragile thing. Among the common reasons, it is worth highlighting the following:

strong pressure on the display;
impact or fall from a great height;
moisture ingress (causes corrosion of microcircuits);
viruses leaked into the system with unverified applications;
manufacturing defects;
controller failure;
rupture or loose connection of the cable;
overheating when charging;
system failure;
unsuccessful flashing or update installation.

And these are not all the possible factors leading to breakdown. If the smartphone is assembled from low-quality parts, then you just need to shake it vigorously - and voila! Something inside will come off. Therefore, there are dozens of nuances, all of them impossible to predict.

Precautionary measures

To avoid such unpleasant consequences, you need to follow the basic rules for using equipment. Smartphones should not be dropped, wet, charged using an inappropriate adapter, or disassembled unnecessarily. You should not give them as a toy to small children, or install applications from suspicious sources. An even better solution would be to install a program that blocks ads, then the phone will definitely not be harmed.

And of course, it’s worth purchasing high-quality equipment. Otherwise, it’s pointless to even be surprised by another breakdown, because nothing else can expect such a “miracle” from the owner.

The tablet didn’t fall, I just held it in my hands and looked at the weather. Suddenly I noticed stripes s on the screen on the right. Thin colored stripes - white, black and even some colored ones. The tablet's desktop has shrunk, but the proportions have remained the same.

The tablet screen, in fact, is divided into 4 parts: on the left at the top there is a reduced desktop, at the bottom there is a strip (the upper part of the desktop), and on the right there are thin colored stripes along the entire height of the tablet screen (the width of the stripe area is 2.5-3 cm). Rebooted with reset - same thing. The tablet became impossible to use - the button images no longer coincided with the corresponding zones on the touch screen: the top left is almost normal, to the right and down everything has shifted diagonally. Hoping that it was a software glitch, I decided to perform a “hard reset” (reset to factory settings). Alas, all without result, just now dial the password for WI-FI succeeded on the eighteenth try...(distressed by the breakdown, I completely forgot that you can connect a mouse to the tablet).

If such color bars had appeared not on a tablet, but for example, on a regular PC everything would have been clear - problems with the video card. Usually, on a PC, the monitor sits quietly on the table (in 97% of cases), and its malfunction from shocks occurs much less frequently than tablet displays, and it is very easy to check a computer monitor. Same thing with the video card - took it out and replaced it - all clear. The “inner world” of a tablet may not be more complicated, but it is definitely smaller and more unknown y.

A fairly long search on the Internet helped me identify the main reasons for the appearance of colored stripes (thin lines) on the screen of tablets and methods for eliminating them.

Reasons for the presence of colored stripes:

Impact, and as a result, damage to the display.
Impact and damage to the cable connecting the motherboard to the display.
Impact and loss of contact in the cable connector.
Software glitch.
Video chip malfunction ( video accelerator, graphics accelerator).

Diagnostic steps and methods.

1. I'll start with the simplest thing - a software failure. Android is reset to factory settings. According to Internet experts, such a step will be enough and flashing will be unnecessary in most cases. Since the screen was somewhat unusable, I reset the tablet to factory settings. Alas, this did not give anything. There is an option with alternative firmware, where there will be a different driver for the tablet’s graphics processor - the probability of success is small.

2. Having disassembled the tablet, I disconnected the display cable, and then carefully attached it. To no avail. The connection seemed to be reliable.

3. After reading several dozen articles about similar tablet malfunctions, I came to the following conclusion: with a 90% probability, the stripes on the tablet screen are a problem in the video chip. What to do:

Expensive tablet. You contact a good, reliable service center, where they will solder in a new video chip for quite a bit of money, perhaps...

Cheap tablet. There are a lot of options here:

Throw away your broken tablet (after all, the price of the tablet is $50 and repairs will cost a similar amount).
Leave it until better times - let it sit.
You sell your tablet on an online flea market for spare parts (touch screen, display, battery or anything else that may interest the buyer).
If the stripes are not all over the screen, then the disabled tablet can be used as an MP3 player or Internet radio. The rest of the live screen can be controlled with the mouse. By the way, this is a good solution for those who have broken their “touchscreen” (touch screen) and are waiting for a new spare part from the online store.
Extreme repair.

There is a method of “extreme repair” of video chips in graphics accelerators of tablets and laptops - “warming up”. Warming up is a dangerous repair method that does not provide a guarantee. The method is that the tablet’s video chip is heated for some time with hot air from an electric hair dryer at the soldering station. In 30-50% of cases there may be a result. A “corrected” tablet can work in this way from 1 day to several months.

There are many blind spots in the “warming up” theory. As far as I understand, numerous short circuits occur in an overheated crystal, and currents bypass faulty areas through closed ones. This combines the features of chip architecture and the properties of pulse circuits as such. I join those who call this method dangerous and categorically do not recommend it.

It will be worse if an adherent of the “warming up” theory comes across you at a service center. For your money, he will conduct an experiment on the tablet, and if the outcome is successful, he will even charge you money for repairs.

P.S.

Developing the topic, we managed to find that “warming up” is often called on the Internet They call it “reballing”. Based on this theory, “home craftsmen” do terrible things. Not having soldering stations at home, they use construction hair dryers and hair dryers, irons and ovens... Here, for example, is a video (I don’t give a link, for obvious reasons) a person shows a tablet, instead of an image on the display there are stripes, then he disassembles the tablet. Shows a gas oven, the thermometer reads over 200 degrees, and places a tablet inside. Shows the timer on the smartphone, which is charged for 5 minutes. Time has passed, he takes out a tablet with a thick mitten. Further on the screen there is an inscription - an hour has passed. He closes the lid, turns it on, and lo and behold, the tablet starts up and works! The video is almost a year old, there are almost 4000 views. It’s a pity that there is no counter for the number of idiots who repeated this experiment.

P.S. 1
Without further ado, I took the receipt and warranty card and took the tablet to the seller for repair. The seller accepted the tablet according to the deed and now several options have appeared:

the tablet will be repaired;
will be replaced with a similar one;
if it cannot be repaired and there is nothing to replace it with, the money will be returned;
they will refuse warranty service based on an inspection by a specialist (there was a case - there was no external damage, but inside the consequences of an impact, namely an impact, were noticeable!)

The seller company sent the tablet to the central office and promised to respond within 28 days... P.S. The seller company returned the full cost of the tablet by receipt a month later, without comment.
