Repair of plasma

Plasma TVs have long won popularity among consumers, because no other screens have such parameters of image quality. But, unfortunately, even such modern technologies have properties to break. On how to make repairs to the plasma, and whether this procedure is possible at home without the involvement of professionals, we'll talk about this article.

What is a plasma screen?

Televisions with a plasma screen appeared much earlier than most of us used to believe - more than fifty years ago. True, the appearance and characteristics of them were far from modern. Today they not only perfectly cope with their main function - the transfer of images, but also are an excellent stylish addition to the interior of rooms - both residential and office. They are easily installed on the table with a special stand, and easily attached to the wall.

Plasma is considered the most optimal option for viewing dynamic scenes in movies, broadcast sports games and bright cartoons with 3D technology.

Important! These screens have the highest quality of color rendering, brightness and contrast, black depth display, as well as the widest viewing angles.

What is this modern wonder of technology?

The structure and operation principle of the plasma screen

The basis of the plasma display is a matrix, which consists of a large number of sealed cells filled with a special mixture of xenon and neon, and coated with phosphors. Conductors are located along the perimeter of the matrix. Through an atmosphere of gas passes an electrical discharge and creates an ultraviolet glow, which contributes to the emission of phosphors. As a result of this action, each cell lights up with the necessary color, and all together they create a picture, which the viewer sees on the screen.

The whole design is limited on both sides by planes( most often glass).If in the first models of plasma displays the thickness of the glasses was 3 mm, then the last screens have thinner planes - only 2 mm. This move reduced the weight of the equipment, but at the same time led to a greater sensitivity of the TV to mechanical damage. The fragility of the screen has increased many times.

Reasons for breakdowns and repair of the plasma TV

Unfortunately, like any other technique, a plasma TV can also break. All types of failures can be divided into the following categories.

plasma panel failure This problem causes the panel to fail or the image to be partially missing. A kind of such trouble is the burnout of the matrix pixels, and if to be more precise - the phosphor layer. Most of all, such a defect is manifested as follows: if you display a static image on the screen, and after changing the frame for a long period of time, the picture remains unchanged. In this case, the repair of the plasma consists in replacing the panel, which qualitatively can only be made by masters, who specialize in the repair of TVs of this type.

Faulty tuner, video processor, electrical circuits, receiver

If the display shows white noise, the problem is a failure in the receiver or tuner. The breakdown of other electronics in most cases leads to distortion or loss of image.

Repair of a plasma TV in such cases is reduced to a soldering in the motherboard of faulty parts or their complete replacement with new ones. Such breakdowns are not uncommon for plasma devices, because they are subjected to a large load on the screen side.

Important! For its normal operation, a high voltage is necessary. For such TVs, a significant consumption of electrical energy is characteristic. Therefore, despite even the protective mechanisms from excessive current in the structure, such malfunctions occur quite often.

Malfunctions of connecting loops and wires, connectors and sockets

In case of careless handling of the equipment, the wires, loops, connectors and sockets may be damaged. Also, in the process of long-term operation, these elements themselves can come to complete unfitness or shake.

If the connectors are not severely damaged, they can be repaired. In more deplorable situations, they are completely replaced by new ones.

Important! Loops and wires, as a rule, are not subject to repair and are replaced by new ones.

Excessive dust inside the cabinet and a malfunction of the

cooling system Such problems lead to overheating of the internal components, which in turn leads to a breakdown of the electronics. Precursors of such troubles are:

• excessive noise of the cooler during the operation of the equipment;
• the TV turns off automatically.

In this case it is better to immediately contact the service center for specialized help. For prevention it is required to regularly clean the case from dust in the center of plasma TV service.

Cracked display

Often, due to inaccurate handling of equipment or by chance, the plasma screen is exposed to mechanical stress. This very often occurs in a house where there are small children and animals. Since the outer glass of the display is very thin, there is no need for special force to damage it.

When the outer shell of the display crackles, the integrity of the matrix is ​​broken and the gas mixture exits. Such a breakdown can not be repaired. In this case, a complete replacement of the matrix is ​​required.

Important! The cost of the matrix is ​​so high that it is sometimes more profitable to purchase a new TV.

When is it better to repair the plasma with such a breakdown, and when - to buy a new technique?

• If the screen is part of the home theater and does not have any other functions than the image translation, then changing the matrix is ​​simply meaningless. It is more profitable to buy a new display.
• If the screen of a plasma TV having a large set of functions cracked, then it is advisable to replace the matrix. However, in this case, it is advantageous to do this procedure only in 20% of cases.
• Sometimes there is no need to replace the matrix - it is enough to simply reconfigure it. This procedure is relevant in cases where the impact on the screen was not strong, and as a result, the gas from the matrix did not come out, but horizontal and vertical strips appeared on the display.

Why it is not necessary to carry out plasma repair yourself?

Sometimes people who do not have experience in repairing such equipment, try to solve the problem on their own. This inevitably leads to even more serious problems and at times the cost of repairs becomes more expensive.

The plasma panel is a high-tech device, so even if you can repair irons and electric kettles, this does not mean that you can easily repair a plasma TV.Accordingly - if there was a breakdown, contact the service center for specialized assistance.

Important! First, look at the warranty period. If the trouble occurred before the end of the specified period, the repair should be carried out for you free of charge, if, of course, the cause of the breakdown is not the improper handling of the equipment.

Actions that reduce the risk of damage to the plasma TV

Like any other technique, the plasma also requires care and proper treatment to yourself. Here are some useful recommendations for such actions:

• The device should be used in a well-ventilated room where regular dust removal is carried out. In this way, the internal components can get good ventilation.
• At least once a year should bring plasma to a specialist for cleaning. Do not allow the accumulation of dust on the outer elements of the body - try to remove it in time with a soft napkin or cloth.
• Since plasma TVs have a limited service life, if the device is not used for viewing, it is better to turn it off so as not to waste time.

Important! Old models of plasma screens have a resource of work equal to 10-15 thousand hours. Newer and more expensive models can boast a little more "shelf life".

• It is recommended not to leave a static picture on the screen for more than 20 minutes. This causes the burning of certain pixels. It is better to change the image or completely turn off the TV.
• To protect the display from the appearance of cracks, you can install on it a special protective acrylic screen. Such screens protect not only from objects accidentally caught in the TV, but also from dust.

If you have a problem with a new plasma TV, do not panic. Perhaps the failure is not so serious, and plasma repair will not require much time and money. That's just in any case, you need to contact a specialist and call him at home for a preliminary diagnosis. It is also necessary to transport the plasma screen correctly, and how to do it depends on the type of failure.
