Repair and replacement of laptop screen

In our time, technical progress touched everyone. Now everyone is accustomed to such devices as computers, mobile phones, tablets. They are created with the help of the latest technologies and eventually acquire an increasingly complex structure. And, of course, like any other machinery or technology, these electronic devices can undergo various breakdowns and malfunctions. This article will cover in detail such an actual problem for many, as a breakdown, as well as replacement of the laptop screen. Why do such troubles arise, how can they be avoided and eliminated?

About the laptop screen device

The laptops themselves, regardless of the model and the manufacturer's preferences, always have a similar design. They consist of a screen and a panel, inside of which is the entire electronic "filling" of the device. Above this panel is a keyboard.

The screen of the laptop also has a rather complex structure. Its basis is a matrix that reproduces the main graphic image. In addition, the device of the screen also includes special loops that connect the matrix to the motherboard, video card and a number of other nodes necessary for normal operation. The matrix is protected from external influences by the case of the laptop, and also by the coatings, which are now made mainly of transparent plastic. But even such a reliable design can be broken. This is due to a number of reasons.

Why did the screen break?

So, what are the most common causes of laptop screen breakdowns? First of all, such troubles are connected with mechanical influences. It can be a blow, the falling of the device on a hard surface, the result of careless handling. In any case, it is these effects that damage the matrix most. As a consequence, you may need to repair or replace the laptop screen.

Another reason is the impact of unfavorable conditions. This range includes such unfavorable factors as moisture, high or low temperature of the air or the device itself, fluctuations and voltage surges, short circuits. They can damage primarily the electronic component of the matrix and its associated chips, circuits and nodes. Therefore, it is very important to protect the laptop from all these adverse effects, and the breakdown may not occur at all.

Symptoms of a broken screen

Evidence that something is wrong with the screen can be quite different manifestations. The screen can transmit a distorted image, reproduce it with fragments. In some cases, there are delays, for example, when watching movies that are not dependent on other circumstances. It often happens that the screen does not give any "signs of life", even if the laptop is turned on normally. It is these alarming events that say it's time to replace the screen.

The breakdown did happen

How can it be, if you can not save the laptop, and the image is either abnormal, or not at all? In this case, you will need urgent repair or replacement of the laptop screen. First of all, it is necessary to learn that independent attempts to repair it will lead to nothing good. A complicated device and a lot of details sometimes puzzles even experienced repairmen, what to say about amateurs. Therefore, at the first opportunity it is necessary to take the broken device to the nearest workshop, which specializes in working with computer equipment.

One of the most easily eliminated problems with the screen is the failure of the backlight lamps. About their malfunction is shown by the darkening of the image, especially at the edges of the screen. Often the image acquires a certain shade and does not change. In this case, you will not have to spend a lot of money, because the lamps are abundant in every service center, and they cost a penny (compared to more complex components).

Laptop Repair: Replacement Screen

Since the matrix is technologically very complex, it must be replaced only if its repair is impossible, for example, due to mechanical impact. In the service center, these facts are taken into account first. In general, the repair procedure includes many complex stages. It:

  • Full analysis of the laptop or (in some cases) the cover of its screen.
  • Further diagnostics of the laptop. It is carried out with the help of complex equipment. It helps to identify such problems, when the interference of the screen image is not always associated with the matrix. In rare cases, this can be caused by problems with the video chip or trains, as well as bridges.
  • If the root of the problem is still in the matrix, then the most suitable replacement is chosen. Usually this takes into account such important parameters as dimensions, mounting methods, screen resolution.
  • Then the installation of the new matrix itself is performed directly. This process may differ depending on the model and the manufacturer of the laptop.
  • After the process of installing the matrix, the laptop is subjected to thorough testing with the help of specially created programs and devices.

In many ways this process can slow down some features. The very diversity of manufacturers, model series and separately produced copies of laptops implies a great experience of the master in working with electronic devices. At the same time, manufacturers, trying to please finicky customers, install on devices of one model line absolutely different in their structure and characteristics of the matrix. And the prices for them significantly fluctuate depending on the rarity. For example, replacing the screen on an Asus laptop may cause the need to search for components that are unique to this manufacturer. But, as a rule, there are no problems with popular brands.

As an example worth considering such famous brands as Packard Bell and Samsung. Each of these manufacturers has its own approach to the manufacture of equipment. Therefore, their matrices can be very different.

Specific requirements for replacing the screen

For example, replacing the screen of a laptop Packard Bell can be quite expensive, because now the goods on their market are difficult to meet, the same situation with the accessories to them. But since the company is part of the company Acer, many parts of their laptops are interchangeable. Directly for matrices, these are details such as the hinges of the cover. In general, these laptops are put matrices manufactured by LG (15.6 inches).

If you need a replacement screen Samsung laptop, you need to consider that all the matrices produced by the company are controlled by their own brand, which makes them even quality, but still have minor flaws, which generally do not affect the laptop. One of these can be attributed to a tendency to overheat, but this happens rarely when observing the necessary rules.
