Plasma repair
Plasma TVs have long gained popularity among consumers, because no other screens have such image quality parameters. But, unfortunately, even such modern technologies have the ability to break. We will talk about how to make a plasma repair, and whether this procedure is possible at home without the involvement of professionals, in this article.
to contents ↑What is a plasma screen?
Televisions with a plasma screen appeared much earlier than most of us are accustomed to consider - more than fifty years ago. True, their appearance and characteristics were far from modern. Today they not only perfectly cope with their main function - image transmission, but they are also a great stylish addition to the interior of rooms - both residential and office. They are easily installed on the table with the help of a special stand, and are also easily mounted on the wall.
Plasma is considered the best option for watching dynamic scenes in movies, broadcasting sports games and vivid cartoons with 3D technology.
Important! It is these screens that have the highest characteristics of color rendering quality, brightness and contrast, displaying the depth of black, as well as the widest viewing angles.
What is this modern miracle of technology?
The structure and principle of operation 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 around the entire perimeter of the matrix. An electric discharge passes through the gaseous medium and creates an ultraviolet glow, which contributes to the luminescence of phosphors. As a result of this action, each cell lights up with the necessary color, and together they create a picture that the viewer sees on the screen.
The whole structure 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 significantly.

Causes of breakdowns and repair of a plasma TV
Unfortunately, like any other technique, a plasma TV can also break. All types of breakdowns can be divided into the following categories.
Plasma panel malfunction
Such a problem leads to a malfunction of the panel or a partial lack of image. A kind of such a nuisance is the burnout of the pixels of the matrix, and to be more precise - the phosphor layer. Most of all, such a defect manifests itself 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 plasma repair consists in replacing the panel, which only masters specializing in the repair of televisions of this type can qualitatively produce.
Important! Usually, such repairs are quite expensive, so it’s more advisable to think about buying a new device. Our articles will help you with this:
Malfunction of the tuner, video processor, electrical circuits, receiver
If white noise appears on the display, then the problem is the malfunction in the malfunction of the receiver or tuner. Failure of other electronics in most cases leads to distortion or loss of image.
Repair of a plasma TV in such cases comes down to re-soldering the faulty parts on the board or completely replacing them with new ones. Such breakdowns are not uncommon for plasma devices, because they are subjected to a large load from the side of the screen.
Important! For its normal operation, high voltage is required. Such televisions are characterized by significant consumption of electrical energy. Therefore, despite the protective mechanisms against excessive current in the structure, such malfunctions occur quite often.
Faulty connecting loops and wires, sockets and sockets
Careless handling of the equipment may damage the wires, loops, connectors and sockets. Also, in the process of long-term operation, these elements by themselves can become completely unusable or loose.
If the connectors are not damaged much, they can be repaired. In more deplorable situations, they are completely replaced with new ones.
Important! Loops and wires, as a rule, cannot be repaired and are replaced by new ones.
Excessive dust inside the case and malfunctioning cooling system
Such problems lead to overheating of the internal components, which in turn leads to breakdown of the electronics. Harbingers of such troubles are:
- excessive cooler noise during operation of the equipment;
- spontaneous shutdown of the TV.
In this case, it is better to immediately contact a service center for specialized assistance. For prevention, you need to regularly clean the case from dust in the service center of plasma TVs.
Cracked display
Often, due to careless handling of equipment or by accident, the plasma screen is subjected to mechanical stress. This very often happens in a house where there are small children and animals. Since the outer glass of the display is very thin, no special force is needed to damage it.
When the outer shell of the display cracks, the integrity of the matrix is violated and the gas mixture escapes. Such a breakdown cannot be repaired. In this case, a complete replacement of the matrix is required.
Important! The cost of the matrix is so high that sometimes it’s more profitable to buy a new TV.
When is it better to repair a plasma with such a breakdown, and when - to buy new equipment?
- If the screen is part of a home theater and has no other functions besides broadcasting an image, then changing the matrix is simply pointless. It’s more profitable to buy a new display.
- If the screen of a plasma TV having a large set of functions is cracked, it is advisable to replace the matrix. However, in this case, it is beneficial to do a similar procedure only in 20% of cases.
- Sometimes there is no need to replace the matrix - just reconfigure it. A similar procedure is relevant in cases where the impact on the screen was not strong, and as a result, the gas did not come out of the matrix, but horizontal and vertical stripes appeared on the display.
Why not repair plasma yourself?
Sometimes people who do not have experience in repairing such equipment try to fix the problem on their own. This inevitably leads to even more serious problems and at times increases the cost of repairs.
The plasma panel is a high-tech device, so even if you can repair irons and electric kettles, then this does not mean that you can easily repair a plasma TV. Accordingly - if there is a breakdown, then contact the service center for specialized assistance.
Important! To get started, look at the warranty period.If the trouble happened before the end of the specified period, then the repair should be carried out for you free of charge, unless, of course, the cause of the breakdown is not improper handling of the equipment.
Actions that reduce the risk of plasma TV breakdowns
Like any other technique, plasma also requires care and proper handling of itself. Here are some helpful suggestions for doing this:
- The device should be used in a well-ventilated area where regular dust cleaning is carried out. Thus, the internal components will be able to get good ventilation. Additionally, you must use and special screen cleaners.
- At least once a year, bring the plasma to a specialist for cleaning. Do not allow dust to accumulate on the external elements of the case - try to clean it in time with a soft cloth or rag.
- Since plasma TVs have a limited life, if the device is not used for viewing, it is better to turn it off so as not to waste time.
Important! Older models of plasma screens have a working life of 10-15 thousand hours. Newer and more expensive models boast a slightly larger “shelf life”.
- It is not recommended to leave a static picture on the screen for more than 20 minutes. This provokes the burnout of certain pixels. It is better to change the image or completely turn off the TV.
- To protect the display from cracks, you can install a special protective acrylic screen on it. Such screens protect not only from objects accidentally caught in the TV, but also from dust. And our tips from a separate article will help you. remove minor scratches on the screen.

If you have any trouble with a new plasma TV, don't panic. Perhaps the breakdown is not so serious, and plasma repair does not require a large investment of time and money. But only in any case, you need to contact a specialist and call him at home for preliminary diagnosis. It is also necessary to transport the plasma screen correctly, and how to do it depends on the type of breakdown.
