Take your phone to a store that sells parts for . Show it to the seller, and he will immediately tell you what kind of screen you need and whether it is in stock.

If you are going to change the display yourself, and you do not have special screwdrivers, purchase them from the same store. Never try to open the phone with a regular screwdriver. You will ruin the slots on the screws, after which it will be impossible to remove them.

Do not put the screen in your pocket - it is very fragile. Carry it home in a bag.

If you even slightly doubt your abilities, it is better to immediately take the phone and display to the nearest workshop.

Put them in a place where they won't get lost.

When disassembling the phone, strictly follow all the recommendations in the manual. Place all parts that are small enough not on the table, but in a jar. Otherwise, you can sweep them off the table and onto the floor with one careless movement. This is especially true for screws. Be sure to write down which length screws fit which holes.

Replacing the display in most cases is carried out without, so a soldering iron is not needed. Carry out this procedure carefully so as not to crush new screen.

Reassemble the phone in reverse order. Be careful to reinstall all removed parts.

Place the SIM card and battery back into the phone. Turn it on and make sure new display. Also make sure that it still has all the buttons, as well as the vibration alert, microphone and speaker.

Many users cell phones throw away their devices and immediately buy new ones if their screens break. In fact, you can save money on buying a new device if you try to replace the failed screen yourself. It's not as difficult as it might seem at first glance.

Instructions

Determine the breakdown. You may see a distorted image, or some pixels may be broken. In this case, you should take it to a service center. With the help of special devices, specialists will quickly bring display in proper condition. If the image on the display is completely absent, or does not respond to pressing (on phones), then, most likely, there is no way around this case.

Remove using a Phillips head screwdriver back panel phone. Simply unscrew the fastening screws inside the battery compartment of the device. Remove the side buttons of the device. Now you have access to his board.

Remove the screws that secure the LCD screen to the front of the phone. Pull the old LCD screen out of the device and set it aside. Place the new LCD screen into the internal compartment of the phone. Fasten all the necessary screws, connect the appropriate cable to the screen.

Smooth out any uneven surfaces on the back panel and press it firmly at all ends of the case mobile phone. Insert the side buttons. Install the battery and back cover devices. Turn on your to test the new LCD screen.

Video on the topic

Almost all of us have speakers, a subwoofer or other devices for transmitting sound with speakers at home. And at least once during operation, the speakers fail. This happens due to a violation of the climate regime, contamination of the speakers, their mechanical damage.

If you learn to deal with the cause of the breakdown, then in half the cases you will be able to eliminate it. A simple screwdriver may be enough to fix it. Sometimes soldering irons, additional soldering irons, glue, chewing gum and other unexpected materials come into play. It is worth considering that modern speakers are thin, so they are more difficult to repair. On the other hand, they are better protected, and this reduces the risk of their breakage.

Here are some small breakdowns and ways to deal with them.

1. If the membrane in the speaker is bent, you can try to shape it. This must be done very carefully, since damage to the structure is irreversible and can worsen the situation.


2. The membrane is attached to the diffuser, sometimes the problem of noise and wheezing is in it. It could have been damaged. Therefore, you need to very carefully unwind the speakers and replace the diffuser. The repair in such a situation is quite complicated, and here it is better to simply replace the entire speaker.


3. Problems may arise due to clogging. Most often, dust, rust or debris gets caught between the magnet and the coil. This leads to the speaker starting to produce “extra” sounds. Everything is simple here. Carefully unscrew the body and get close to the speaker. Then wrap cotton wool soaked in the match around the match and remove the debris. It is important not to disturb the wires and connections of the speaker.


4. If the wires that go to the diffuser are broken or damaged, then they need to be restored. In this case, the speaker can only be repaired with a soldering iron. Breakage becomes the result of constant dynamics; to avoid it, the wires must be strengthened.


5. One of the most complex options, this is when the magnet of the speaker “drives”. Most often this happens due to the proximity of other magnets and temperature changes. There is only one recipe - replacing the magnet, and better dynamics generally. So a magnet of the same strength can be difficult.


6. If the integrity of the “speaker dish” is damaged, you should try replacing it or making a similar one from paper. The latter is very short-lived and doubtful.

In general, repairing speakers is not difficult, the main thing is to have at least basic concepts in physics and acoustics. If you want to avoid such tests, buy closed-type speakers, and if they break, just replace them.

Modern people They simply don’t feel comfortable without phones, even if they hardly use them.

However, constant contact with technology requires us to have some new knowledge. That is, if you want to use technology, be prepared for the fact that you will need to learn basic skills about your devices. A problem that is encountered very often is the malfunction of microphones in phones, headsets and microphones to computers. Note that repairing a microphone is usually not difficult, the repair is simple. However, most often we waste time and nerves taking the microphone to the workshop.

There are three common problems that cause microphone failure. If you consider the problem carefully, you can solve it yourself.

1. The microphone loses sensitivity due to clogging. Dust, microparticles of skin, small debris fall on the sound-sensitive head and it loses its properties. To repair the microphone in this case, you need cotton wool and a screwdriver. You need to release the microphone. To do this, sometimes you need to unscrew the case, or from it. Then dip the cotton wool in alcohol and very carefully remove the plaque from the head. Make sure that the cotton wool does not remain on it. Let the alcohol evaporate and place the microphone back.


2. The microphone loses sensitivity due to moisture. Sometimes condensation gets trapped between the gaskets and the head. As a rule, the head itself does not rust, but moisture does its job. You need to again release the head and warm it up under an incandescent lamp. If there are gaskets, you should do the same and remove them.


3. The microphone fails due to a break in the incoming wire. There are two options here - change, or. They need to be applied based on the specific situation. In phones, most often you need to solder the broken one. In, there are situations where the wire is broken in several places, in which case it’s better to change everything.

If the problems are more serious, they change the entire unit, especially when it comes to the phone. As for, it’s better to just replace it completely.

Almost every apartment has home phone. With its help, you can contact a subscriber located almost anywhere in the world. However, telephone sets tend to break down. Specialized repair services are sometimes very expensive. What to do? Repair your phone yourself.

In general, the picture turned out to be as follows:

Then a decline in mood, because the device is only 3 months old, a trip to eBay, etc. After googling the Internet, I decided to try various programs from Google Play on restoration dead pixels. Their meaning boils down to the fact that they heat up the pixels by quickly changing the color of the screen image (or a separate part of it). The pixel restoration program worked for about an hour and no changes on the screen, for the better, occurred. By evening, I began to notice that these “dots” of broken pixels had turned into stripes, and one of the stripes grew before my eyes. In general, by the evening I already had a bunch of horizontal stripes.

While I was waiting for an answer from eBay about the manufacturer of the display, I read the forums and came across one topic where a guy with the same phone encountered the same problem as me. One fine winter evening, having arrived home, he forgot his phone in the car, and the car spent the night on the street. It's -15 outside. When he got into the car in the morning and unlocked the phone, he saw that most of the “dead” pixels miraculously came back to life. The next night I decided to leave the phone again to “freeze” in the car and what do you think, every single dead pixel “came to life”.

When I read that topic on the forum, at first I thought it was complete nonsense. If I’m going to order a display anyway, then fine, I’ll put it in the freezer (my wife somehow reacted warily to this, but I didn’t explain anything). Naturally, I first took out the battery, SIM card and card. Of course, I couldn’t stand it all night, I pulled it out after 5 minutes and was amazed, 1/3 of the dead pixels were restored in 5 minutes. I put it in for another 5 minutes, took it out, and the stripes turned into dots. Then I became wary, because... After I took the phone out of the freezer, it quickly became covered with frost, which immediately melted, and this could lead to moisture getting into the display or oxidation of the contacts. I didn’t experiment anymore and put it in the freezer until the morning.

In the morning my expectations were justified, absolutely all the pixels were restored.

On communicators with capacitive touchscreens, the method of “massaging” the pixels is not applicable (since touchscreens are hard and it is physically impossible to press on the display itself), although it is described as very effective.

Also, some argue that freezing shortens the life of the display - nothing of the kind. The JVC Mafon has been living there in a car with an LCD display since 2005. The car sits outside all year round, and the frosts in the north are -50 and yet nothing happens to it and there is not a single dead pixel.

So take advantage.
Good luck.

Important:
This may not apply to all displays. This article concerns only my HTC Sensation. Type TFT matrices Super LCD (judging by the descriptions on the Internet - based on liquid crystal matrix).
I tried to apply the same method on Nokia 6300 (There is a normal TFT display - based on transistor matrix), the result was the opposite. The dots turned into stripes, some kind of yellow ones.

Possible explanation for this method(Thank you oENDark):

Let me add:
A broken crystal is in an energetically unfavorable position, it is “twisted”, so to speak, and in addition to the above, “Freezing” causes it to “unscrew”
Because external influence in the form of a blow, it made him “crouch” and added internal tension to him, the freezing takes away part of his internal energy and he cannot resist the internal tension and straightens up.

• The phone only displays White screen. In this case, there may be problems such as a faulty controller on the board, the cable is damaged, the program has crashed, or the display needs to be replaced.
• The display glows blue - there is a problem with either the controller or the screen itself.
• Ripples appear on the screen - the controller is faulty or the screen needs to be replaced.

• The picture is hard to see, but the screen still works - in most cases this indicates a malfunction of the backlight circuit.

Important! Do not put off going to the service center if you notice any malfunctions in the operation of your gadget’s screen. The sooner you do this, the easier it will be to get your phone working again. If, based on the diagnostic results, it turns out that repairs will be unprofitable, we suggest that you take a look immediately optimal model for purchase. Our reviews will help you with this:

Temporary solutions

If the cracks on the screen are not very large, you can try to fix the situation yourself. The options proposed below are only suitable if the functionality of the gadget is not impaired, that is, the sensor works:

• Try to carefully polish the crack special means type or very fine-grain sandpaper.
• As a temporary solution - or, which will “fix” the screen in its current state and prevent the crack from growing in size.

Replacing the touch screen

Touchscreen phones have become very popular because they are easy to use. The touch screen or touchscreen is part modern smartphones, which is the most vulnerable. It is usually made of fragile glass or plastic, which can easily be broken, spilled, or scratched. If the glass on your smartphone is cracked, what should you do? Don't worry! Replacing the touchscreen is not that difficult, and it only takes a little time.

Important! Touch screens, which are completely broken and do not work, cannot be repaired! Be extremely careful with them.

Touch glass replacement is required:

• There are cracks on it.
• The touchscreen does not respond to touches or does whatever it wants.
• The smartphone freezes when pressed.

Important! The sensor is made of several active layers - if one of them is damaged, the touchscreen will not work. Very often, if the screen does not respond to touch, it is necessary to replace the glass, not the screen. In most cases it will cost much less.

If the image becomes unclear, is not fully displayed, blackouts appear, or the picture is not visible at all, the entire screen must be replaced.

Should I change the screen myself?

If you're a jack of all trades, you can try replacing the screen yourself. To do this you will need: a new display and special screwdrivers.

To begin, turn off your mobile device and remove the battery and SIM cards from it, select screwdrivers suitable for your phone. Next use step by step instructions, which are suitable for your phone model, since in different models There are different nuances - you can find them on the Internet.

The vast majority of faults portable devices occurs due to the fault of their owners. For example, a broken screen on a phone clearly cannot be attributed to a manufacturing defect. Careless operation of equipment leads to the fact that devices often fall and break. Sometimes the case gets damaged, but the glass screen in a phone is one of the most fragile elements, so it is the one that suffers first.

Characteristics of damage

To assess the extent of the damage, you should first check the functionality of the gadget. If the device responds to movements, displays data, plays sound and does not glitch, it means we're talking about only about glass damage. Otherwise, more serious problems should be noted, the main of which is screen breakage. The smartphone display consists of glass and a matrix to which the board is connected. The failure of the matrix does not allow the use of the equipment - all that can be seen is a black screen.

Broken glass allows you to use the phone for the time being, since the growth of cracks over time will not allow you to use the gadget normally, as it will be inconvenient. Yes and appearance such a smartphone would be very pitiful. More serious problems arise when the cable breaks or other components become damaged. In this case, additional repairs are added to the replacement of the phone screen.

Can the screen be repaired?

If we talk about repairing the display, in this case we can only talk about glass repair, and even then only for the period necessary to make a decision about replacing it. In order to use a phone with a broken sensor, it is necessary to properly seal the touchscreen so that the cracks do not grow, and the fragments do not fall out and could not injure the user.

For this purpose, adhesive tape or tape is used, with the help of which the glass is hermetically sealed, thus creating its integrity. Ease of use mobile device in this case, it will completely depend on the area the damage occupies. If the defect is located in one of the corners and is small, interference during navigation will be minimal; in all other cases, the operation of the equipment will be quite annoying.

To replace the glass (and this will be the best decision), you need to carefully remove the old sensor and install a new one, which still needs to be purchased correctly. It is best to contact a service center that repairs phones, where specialists will do everything themselves, and you will receive an absolutely serviceable device.

If the device does not respond to user actions, it is necessary to change the screen. The matrix of a smartphone has a very complex structure, so there is no point in repairing it in case of mechanical damage - it is better to purchase a new one.

In order to properly replace your phone screen, you need to call a technician, for which it is best to contact a reliable service center. Such organizations employ the most qualified specialists who have passed a rigorous selection process, so the company always provides a guarantee for repairs.

It is not recommended to replace the display on a smartphone yourself, since without the proper experience and knowledge, the device can be damaged very easily. The fact is that we are talking about very small, but vitally important parts for the phone, many of which must be removed when replacing the screen. In addition, you will have to deal with disconnecting the cables, the fastening of which will also be a complete mystery for the inexperienced user.

Replacement of the matrix is ​​carried out with special tools, which a priori do not have ordinary person. Does it make sense to purchase professional tools for a one-time repair? The services of a master will cost less. To properly repair a phone display, the technician almost completely disassembles it and checks for possible damage to other parts. Timely identification of problems will protect your smartphone from accidental breakdowns in the future.

When ordering repairs from a service center, the user usually receives free recommendations on the correct operation of the phone and proper care for it so that the device works smoothly throughout long period time. One of the measures that will help protect the screen and body of the phone from shock is to purchase protective cover. This element is inexpensive, but, as practice shows, it is very effective.

Also a specialist service center will optimally configure the phone so that it uses the charge efficiently. The wizard will show the user how this is done, so that in the future the owner of the smartphone can make such settings independently. A specialist will tell you under what conditions it is best to store your phone so that it does not overheat or is not exposed to low temperatures. All tips and recommendations are worth taking into account, as they can significantly extend the life of the gadget.
