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

The fact is that we are talking about very small in size, but vital details for the phone, many of which must be removed when replacing the screen. In addition, you will have to deal with disconnecting cables, the fastening of which will also be a complete mystery to an inexperienced user.
The matrix is replaced with special tools that an ordinary person does not have a priori. Does it make sense to purchase professional tools for a one-time repair? The services of a master will cost less. In order to qualitatively repair the phone display, the master almost completely disassembles it and checks for possible damage to other parts. Timely detection of problems will save the smartphone from accidental breakdowns in the future.

Plasma TVs have long since become permanent cohabitants in our apartments, because such devices produce a very high-quality image. The image quality is ideal for action movies, sports events, and even cartoons. But then a weighty children's toy flies at the TV, and your “electronic friend” stops transmitting the image, showing only a crack that has appeared with colored stripes on the display. What to do in such cases? Can an LCD TV be repaired if the screen is broken? Do not rush to be sad, perhaps this article will help you find the most optimal solution such a problem.
What is a plasma TV screen?
The main component of such a screen is a matrix. The matrix contains just a huge number of particles that are filled with a mixture of neon and xenon. The perimeter of the matrix is framed by semiconductors. Electricity passes through the gaseous medium and creates a UV glow, which causes the phosphors to glow. This whole cunning process leads to the glow of the cell with the desired color, and in the aggregate, tens of thousands of cells form the picture that we observe every day.
The entire screen device is located in a relatively small space between two planes, which are usually made of special glass.
Important! Previously, models could boast of glass thickness, which was only 3 millimeters. But progress, together with manufacturers, has been made by new models with a thickness of only 2 millimeters. Such innovations have significantly reduced the weight of the device, but made it even more fragile, which leads to fraught consequences.
Can a cracked LCD TV screen be repaired? Let's talk about it.
If the display is cracked
Cracks on the outer glass violate the integrity of the matrix, and the gas mixture freely leaves its “reservoir”. Such a malfunction cannot be repaired. The only way out is to buy a new matrix.

Experienced users recommend not to repair plasma panels, which are a component home theater and do not have any audio output devices or other useful components. This case will definitely require the purchase of a new panel. But if a plasma TV with a huge set of functions is broken, then it will already be possible to speculate. But it should be understood that only in 1 out of 5 cases it will be profitable to repair.
Therefore, immediately read it, you may decide that buying a new TV will still be more profitable.
Still decided to change the matrix?
The matrix can be repaired, but even here you will have to upset you a little: you cannot do repairs at home, and even here there are huge difficulties - this is the transportation of plasma. Experts recommend transporting such equipment only in an upright position and avoid any tilt angles so as not to cause overload.
Important! If you are a happy owner of a huge plasma, and you have a small car in your yard, then you will have to fork out not only for repairs, but also for the transportation of a broken device.
Before sending the “corpse” of the TV to the technical center, once again make sure that all manipulations are cost-effective. To avoid huge idle costs, it is recommended to call the master at home. A specialist will come, diagnose and put forward a decision with which it is best to agree. Also, in addition to diagnostics, for a small fee, the masters themselves will transport the TV in compliance with all safety regulations. You will only need to agree on the questions about the meeting and make a decision, wait a couple of days and go for the finished TV.

If you protect your equipment, you will be able to watch football, movies or cartoons for a long time.
There is also another preventive TV care measure. To do this, you need to purchase a bracket. Using the bracket allows you to install the plasma directly under the ceiling. Such measures will help to avoid accidental “back pushing” or the consequences of children's active games at home. True, the bracket will cost a little more, and its installation is a completely separate issue.
Users laptop computers often worries about the breakage or loss of a key. After all, even one key that is out of order can cause great inconvenience when working with a laptop. Moreover, given the huge variety of computer models, repair tips for one may not be suitable for another. Each laptop has its own keyboard design. Therefore, before using general recommendations for repairing a key without resorting to the services of specialists, it is necessary to determine the model of a computer device.
Causes of broken keys
Most laptops have fairly thin keyboards with little key travel. This leads to the fact that this part is most often subjected to mechanical influences. The most common causes of failure can be:
- accidentally spilled liquid;
- clogging with household dust, dirt, pet hair;
- incorrect user actions during self-cleaning of the keyboard, and so on.
Of course, any breakdown caused by one of these causes is unpleasant. However, after reading the necessary recommendations, the user himself can repair the key.
In addition to the named causes of failure, there is also a factory defect or low-quality parts, as well as software malfunctions, leading to disruption of the operation of one key or the entire keyboard. Only service centers are involved in eliminating such causes, since for this, first of all, it is necessary to conduct a comprehensive diagnosis.
What to do as a result of a broken key
Although laptop models differ from each other, the keys, as a rule, are attached in the same way. The button on the keyboard is a rubber base with a built-in contact. In the process of pressing, the contact touches the circuit, as a result of which the desired action is performed. Therefore, you must first of all ensure that this contact is correctly installed.
Of course, from the very beginning it is necessary to find out the cause of the damage. If the button sticks, you should try to pull it out using a special screwdriver or a thick needle. To do this, the end of the tool must be brought under the key and gently pulled up. It is worth remembering that as a result of such an action, in no case should you apply a lot of force, since the key can be damaged, and this already leads to additional financial costs.
After pulling out the key, you need to examine it well and find out the cause of the damage. Of course, if the button cannot be restored, then it must be replaced with a new one, which can be purchased at any computer repair shop.
Sometimes a key can simply be glued with super glue, however, when installing it in place, you need to make sure that the contact is in the right place. Otherwise, the breakdown will not be repaired.
In the event of a key falling out, first of all, it is necessary to carefully consider the design of its fastening. On the reverse side The buttons are placed grooves and latches with "ears" of the rocker. They are designed to connect the keyboard to the cover of each individual button. If the key fell out along with the rocker, then they must be separated. After that, you need to install the rocker itself, on which the key cover is located. These two parts are connected using grooves located directly on them.
It is worth remembering that before installing the element in place, it is necessary to tidy up the opened niche, while removing all the dirt with a napkin.
It is much more difficult to repair a breakdown that is caused by an accidentally spilled liquid. Indeed, in this case, contacts are blurred, which, in most cases, are almost impossible to restore on your own. With such damage, it is best to contact the service center specialists or try to change the keyboard yourself.
Do-it-yourself laptop keyboard replacement
Such manipulations should be carried out very carefully so as not to cause even more harm to the laptop. First of all, you need to turn off the power, including pulling out the battery.
Basically, the keyboard is attached to the base of the device using special latches or screws, which can be easily removed. After that, you need to disconnect the cable that connects the keyboard to other devices. It is a rather fragile structure, which can be easily damaged if careless. When replacing the keyboard, the cable must be disconnected by pulling up on the black frame.
There are no particular difficulties in performing such actions. The only thing to remember is to be careful when working with fragile parts. So any user, having read the recommendations, can independently repair not only broken keys, but also the keyboard itself.
