Still, we decided to change the matrix?
The matrix can be repaired, but even here you will have to upset you a little: you cannot repair at home, and even here enormous difficulties arise. this is the transportation of plasma. Experts recommend transporting such equipment only in an upright position and avoiding 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 the yard, you will have to fork out not only for repairs, but also for the transportation of a broken apparatus.
Before sending the “corpse” of the TV set to the technical center, make sure once again that all manipulations are profitable. To avoid huge idle costs, it is recommended to call a foreman at home. A specialist will come, carry out diagnostics and put forward a solution with which it is best to agree, it may be necessary to replace some parts. Also, in addition to diagnostics, for a small fee, the masters will transport the TV themselves in compliance with all safety rules. You will only need to agree on the meeting and make a decision, wait a couple of days and go to the finished TV.
Important! Can LCD TV be repaired if there are streaks or spots on the screen? You can, and read about this in more detail in the articles:
It is best to try to avoid such breakage in the future.
A repaired TV arrives at your home, but children, animals, or a clumsy family member can still shatter the screen? Something needs to be done urgently.
For such TVs, special protective screens made of acrylic are produced. Such surfaces are not afraid of water, scratches, and children will be able to throw their toys at the screen without forcing their parents to take a loan for a new device. In addition, such protection saves from dust, which, by the way, is also the old sworn enemy of televisions. Therefore, the purchase of an “accessory” is the most popular. If you protect your equipment, you will be able to watch football, films or cartoons for a long time.
There is also another preventive TV care measure. To do this, you need to purchase a bracket. The use of the bracket allows the installation of the plasma directly under the ceiling. Such measures will help to avoid accidental “pushing back” or the consequences of children’s active play at home. True, the bracket will cost a little more, and its installation is a completely separate topic.
What is a plasma TV screen?
The main component of such a screen is the matrix. The matrix contains a huge number of particles that are filled with a mixture of neon and xenon. The perimeter of the matrix is framed by semiconductors. An electric current passes through the gas environment and creates UV light, which causes the phosphors to glow. This whole tricky 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 boasted a glass thickness of only 3 millimeters. But progress together with manufacturers have made 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 broken LCD TV screen be repaired if it is cracked? Let’s talk about it.
Plasma TVs have long ago become permanent cohabitants in our apartments, because such devices give a very high-quality image. The image quality is ideal for action films, sports competitions, and even cartoons. But then a weighty children’s toy flies into the TV, and your “electronic friend” stops transmitting the image, showing only a crack with colored stripes on the display. What to do in such cases? Can LCD TV be repaired if the screen is broken? Take your time to be sad, perhaps this article will help you find the most optimal solution to such a problem.
If the display is cracked
Cracks on the outer glass violate the integrity of the matrix, and the gas mixture freely leaves its “reservoir”. This malfunction cannot be repaired. Only one way out is to buy a new matrix.
Important! The matrix of the device costs almost the same as the TV itself, so it is often easier to purchase a new TV.
Experienced users recommend not to repair plasma panels, which are a home theater component and do not have any sound 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 is worthwhile to understand that only in 1 out of 5 cases it will be profitable to repair. Most likely you will need to replace the TV.
Therefore, immediately check out the rating of the best LED TVs 40 inches, perhaps you decide that buying a new TV will still be more profitable, instead of fixing a TV that fell and crashed.
Important! Remember that the quality of any device largely depends on the brand and place of assembly of the device. Find out where different brands of TVs are collected.
Matrix replacement problems
If you have made the decision to change the matrix, you should adhere to several important points:
- This procedure is not carried out at home, and even more so independently. You need to bring the broken TV to an experienced technician for repair.
- It is recommended to keep the plasma display in an upright position during transportation. This will help to avoid incorrect redistribution of the load on one of the sides. That is, often in order to transport the injured TV, a car will not be enough for you.
Important! Conveniently, today you can easily call a wizard at home, who will help diagnose the magnitude of the problem and determine whether it is possible to repair the plasma TV if the screen is broken and whether it is necessary to change the matrix. The company will also help you deliver your TV to the service center and back, observing all the necessary transportation rules.
It is impossible to argue that prevention is the best defense. Manufacturers have already created many ways to protect. One of them is an acrylic screen protector. Its advantage is that, unlike the TV screens themselves, they can be wet with water, scratched or even light blows.
Important! This type of screen will help protect the original panel from mechanical damage, which is extremely important, as well as from dirt, dust, which is considered the enemy of nanotechnology.
So, if you want to protect your plasma TV from damage, and even more so if the cost of equipment is high enough, we advise you to purchase this protection option. An acrylic protective screen is very useful and necessary in a house with children, because one careless movement can lead to large losses.
Important! If the resume of the masters from the service center is unambiguous. the panel cannot be repaired, you will have to buy a new TV. You will be helped to choose a high-quality model and correctly position it in the room:
Is it necessary to change the matrix?
There is no single unequivocal answer to this question and will not be. The whole point is that every situation requires an individual solution. We can only tell you about the basic principles and help you make your decision. So, if you have broken your TV, the first thing to look out for is the brand of the device, the cost, and the amount of damage.
If the TV was bought a long time ago, then the manufacturer may already stop producing matrices for your model. In this case, you will have to either buy new equipment, or look for the necessary part in repair centers.
Important! So, for example, the well-known Japanese company Panasonic has ceased to produce plasma, respectively. and matrices.
Expensive TVs with a large set of functionality should be tried to be repaired, because this way you can save more than half.
Also, it is worth emphasizing that sometimes the damage is not so large-scale, which means that you can try not to replace, but to reconfigure the matrix. If, as a result of the impact, the gas did not leave the matrix, but only incomprehensible vertical and horizontal stripes formed on the screen, the situation can be corrected. To do this, take the broken TV to a service center.
Important! The huge advantage is that the cost of reconfiguring is not that high.
Plasma screen. what is it?
First, let’s figure out what a plasma screen is and how does it project an image? The matrix is the basis of such a TV and contains a huge number of cells, inside which there is a mixture of xenon and neon. These cells are covered with phosphors. Also, special conductors are located around the perimeter, which contribute to the formation of ultraviolet light during its passage through the gaseous environment. This is what causes the cells to light up and glow in a given color. As a result, we can observe a complete image.
Such a complex mechanism is located between two, often glass, planes. But if earlier the thickness was 3 mm, today, in order to facilitate and slightly reduce the technique, manufacturers have made thinner planes, namely 2 mm.
Important! Indeed, as expected, the weight became less, but the sensitivity to mechanical influences and fragility increased significantly.
What to do if the screen is cracked?
If you nevertheless break the TV, for example, after a fall, or rather a plasma screen, then the integrity and correct functioning of the matrix is violated. Since the gas mixture comes out through cracks or cracks, you can forget about a good image. It is also bad that this malfunction cannot be repaired. in any case, you will have to change the matrix.
Important! As a rule, the cost of this part of the TV reaches huge sums, so it is often easier to buy new equipment than to try to fix a broken TV. But you can still contact the workshop and find out how much it costs to repair the TV. Remember also that the cost of components largely depends on the manufacturer and the country of assembly. To understand the difference more, read about where LG, Samsung, and other brands are assembled.
In cases where you have a plasma panel installed, which is part of a home theater, and the sound system and other important functions do not depend on the broken panel, it is undesirable to change the matrix, since it is pointless. In such a situation, it is much easier, more profitable and faster to buy a new TV again.
Important! But if the situation is radically opposite. the TV has many functions and options, then replacing the matrix will be much more appropriate.
However, a TV set, especially a plasma TV, is a very expensive pleasure. We advise you to consult in advance with the wizard on the topic: is it possible to fix the LCD TV if the screen is broken, and find out the most suitable solution to the problem.
If the picture freezes, then such a breakdown occurs for several reasons:
- No signal from the receiving module to the input device of the video amplifier. To diagnose such a breakdown, you should connect some other video signal source, for example, a set-top box, laptop, PC or VCR, to the “Video” socket located on the TV case. If the image appears, then the cause of the equipment malfunction is the tuner or microcontroller, as well as their circuits.
- The microcontroller is checked quite quickly. it is responsible for the functionality of the buttons of all output audio and video signals. If by pressing a key you can enter the menu and it appears on the display. the microcontroller is not to blame. Then it is worth checking all the potentials on its legs with a multimeter. If they fully coincide with the values of the circuit, then you will have to replace the tuner.
- The cause of the breakdown may also be a malfunction of the video processor. If, after connecting to the tuner elements, the audio sequence does not appear again, you need to check the video processor, that is, the entire microcircuit as a whole. To do this, check the output and power supply circuits to ensure that their values correspond to the required operating potentials. If you find such a discrepancy, you can say with a 70% probability that the processor is broken.
DIY LCD TV repair
Televisions have long and firmly taken their place in the life of every modern person, therefore, a breakdown of a TV receiver can fundamentally ruin the mood of any of its owners, especially since new units are not cheap at all. That is why, in the event of a malfunction, each person has a question. whether it is necessary to go to a service center and where to find a good master, is it worth spending your time on repairs and, most importantly, money. Of course, these are important questions, but before turning to the services of paid specialists, try to determine the cause of the breakdown and, if possible, fix it. in some cases, repairing electrical equipment at home is possible.
In order to carry out an independent repair of TV receivers, it is necessary to determine the root cause of the breakdown. This will require:
- multimeter. this device is necessary for determining the voltage parameters in the control sections of the measurement, the ratings of capacitors and resistors, as well as the continuity of electrical circuits;
- amplifier. used to identify the area where the signal disappears;
- oscilloscope. required to represent signals at several points of the functional diagram of a TV device.
The most common causes of malfunctions:
- The receiver does not start. the reason is usually the failure of the power supply, as well as damage to the cable or breakdown of the power button.
- The screen does not light up or the video sequence looks blurry, barely noticeable. this directly indicates problems with the backlight LEDs, light bulbs or their power sources.
- The TV wheezes or there is no sound reproduction at all. in this case, most likely there are interruptions in the operation of the audio amplifier or strapping.
- The TV receiver screen is lit, but there is no image. this indicates an interruption in the operation of the tuner, as well as its circuits, or a breakdown of the video card.
Another common cause of TV breakdown is mechanical damage to the screen. In this case, you can notice the problem with the naked eye. a broken monitor, cracks, a broken matrix, light and dark spots on the screen will indicate it.
We draw your attention to the fact that if during an external examination of television equipment you notice a rupture of elements, swelling, carbon deposits or darkening on the board, do not rush to repair the damaged parts.
It is possible that the burned-out component is only a consequence of a short circuit, and its real cause is located in a completely different place.
Does not turn on
If the TV receiver does not turn on, then most likely the reason for such a problem is a power supply malfunction, an activation button and wire defects.
To determine the cause of the problem associated with the cable and the button, you need to ring the elements with a tester, and the malfunction should be determined not only in the on, but also in the off state.
With the power supply unit, the situation is much more complicated. if during a visual inspection you notice damaged parts, this does not mean at all that by replacing them, you will get a properly working equipment. For example, capacitors may well swell from overvoltage, long-term use, or due to a secondary circuit, the source of which is contained in a completely different circuit.
That is why it is necessary to ring all the power supply elements with a multimeter. Do it in the following sequence.
- If the air conditioner swells, the posistor cracked, some other visually detectable defect is noticeable, then the part should be carefully evaporated and cleaned of electrolytes and carbon deposits.
- The tester is checked starting with the fuse, as well as the posistor, then the diode bridge is called, then the transistors, resistors and finally the microcircuit. If during the diagnostics no interruptions were detected, you just need to replace the old working elements.
No sound or wheezing
Such a breakdown is usually associated with a breakdown of the sound path. Before eliminating it, you should ring all the supply, as well as the output voltage values on the legs of the sound amplifier microcircuit. This should be done by a tester, referring to the working diagrams. If the indicators are normal, then the cause of the violation lies in the capacitors.
If there is no power at all or it is too low, then it is possible that the current does not come from the power supply unit. In this case, you should ring all the elements that go from the power supply unit to the sound device. Failed parts are exchanged for workers.
It is easy to check the state of the microcircuit. you need to remove it from the socket. If after that the voltage on the tester appears and its value is normal, then the microcircuit will have to be changed to a new one.
The screen does not light up
If there is sound, but the panel does not light up, this may indicate a malfunction in the lighting circuit. There may be two reasons for this:
- interruptions in the operation of lamps: LED or lamps;
- lack of power supply to the backlight.
If you have a LCD TV, then the backlighting is lamp, in all other models it is LED.
Typically, any LCD TV has 1 to 10 bulbs. They all burn out very rarely at once, most often the lamp itself is faulty. In this case, TV repairs are performed as follows:
- open the case;
- carefully remove all driver boards, as well as the power supply;
- disassemble the screen module, for this they remove both covers, if any, as well as the protective film;
- inspect the LED strip or light bulbs, if necessary, replace them;
- the rest of the target is checked visually, and then with a tester. this will make sure that there are no breaks in the diode tape.
A more detailed overview of replacing non-working lamps using the example of a Sharp LCD TV is presented in the following
If all the lamps do not light up at once, then with a high degree of probability the problem is reduced to the power supply of the backlight. As a rule, high-voltage converters are used in liquid crystal and plasma technology. Violation in their starting circuits can be easily determined with a multimeter. To do this, you need to measure the voltage on the knives in exact comparison with the working diagram. As soon as you find inconsistencies, you can replace the elements with serviceable ones.
But it will be much more difficult to make sure that the transformer is working. To do this, you need to measure the voltage across all microelements of the converter. If the parameters are normal in each, then the transformer is to blame. If you want, you can rewind it over again, but this is a very troublesome task. And the quality of such winding leaves much to be desired. sooner or later, the equipment fails again. The best option would be to buy a new one.
In LED backlight transformers, the potential difference is usually between 50 and 100 W. If it is not present on the connectors, you should check how many volts goes to the old transformer. To do this, you must first remove it. If the parameters are normal, the transformer should be replaced, and if not, then it is worth continuing to check the remaining parts of the converter.
Is it possible to repair the screen
If the LCD TV is dropped or you accidentally hit it with a heavy object, the panel will break. And in fact, and in another case, the question arises: is it possible to fix the screen after an impact at home?
If you do not have the skills to work with electronic equipment, the answer will be negative. you cannot do it with your own hands, all the necessary work must be entrusted to specialists by contacting a repair shop.
Keep in mind. the cost of such repairs usually costs a “tidy” amount, comparable to the price of a new receiver.
The situation is no better with the breakdown of the screen caused by damage to the matrix. In this case, you may notice a partial absence of a picture, light or dark spots, stripes. To eliminate all the unpleasant consequences associated with this problem, it needs to be changed. These works should also be performed only by qualified technicians, since any repair at home can aggravate the situation and lead to the permanent failure of your TV.
Does not turn on
If the TV does not turn on, then the reasons for such a malfunction can be very diverse, ranging from problems with the electrics and ending with a failed control module. In any case, you will not be able to identify the problem yourself, as well as fix the unit. this will require professional equipment. In some cases, when it comes to a faulty electronic board, the cost of repairs will be comparable to the cost of buying a new TV.
Remote control does not work
The most common reason the remote control does not work is because of its old batteries. First, try inserting new ones, if after replacing the problems do not disappear anywhere, then you need to try to check the operation of the remote control. You cannot see infrared radiation with your own eyes, but it is beautifully displayed in photographs. Diagnostics is simple: point your phone camera at the module and take a picture at the moment when you press the buttons. If you notice a glow in the photo, it means that the remote control is working properly, otherwise it needs to be repaired or bought a new one.
Image is too dim
If you see an overly dim image, then you are probably dealing with a failure of the backlight indicators. The fact is that in Samsung TVs, the LEDs are connected in series, so if even one lamp burns out, you will have to replace the entire system.
The screen lights up, but there is no picture
Usually this situation occurs when the signal from the receiving unit is not fed to the input of the graphic amplifier. This indicates that the tuner is defective or its circuit is damaged. To test the TV receiver, you need to connect an alternative signal source: it can be a laptop, personal computer or smartphone. If, as a result, a picture appears, then you are dealing with a breakdown of the microcontroller. it needs to be replaced. You can perform such work only after having disassembled the entire TV set.
All malfunctions associated with hardware failures can only be eliminated by experienced technicians. Therefore, if dots, stripes appear on the display, or the power supply unit of Samsung TVs burns out, then you must definitely contact the service department.
Smart TV problems
In some cases, users are faced with distortion of audio and video sequences. Samsung TV receivers, especially the latest models, are prone to problems with software glitches in the Smart TV app. In order to neutralize them, it is necessary to regularly update the firmware, while the automatic update option should be turned off.
Samsung TV repair
Premature failure of Samsung TVs often becomes the reason that the owner is faced with the question: “Is it worth trying to repair the device on your own, or is it better to turn to professionals for help?” The answer depends only on the nature of the malfunction: some failures are minor, so they can be dealt with at home, while others require the intervention of service center specialists. Let’s dwell on each of them in more detail.
Malfunctions and diagnostics
If you’ve just bought a Samsung TV, whether it’s plasma, CRT or LCD, the chances are very low that it’s broken. The only reason may be a factory defect, which happens extremely rarely, or your own carelessness in case you did something wrong at the time of transportation or connection of the equipment.
If your equipment has been functioning properly for some time, but suddenly, when you try to turn it on, it stopped working, then looking for the cause of such a problem, according to certain signs, will help determine whether it is worth trying to cope with the breakdown with your own hands.
Often, users of TV-receivers begin to panic and call the wizard at the most elementary malfunctions in the TV. Do not do this. first try to diagnose yourself.
First, check what operating mode your TV receiver is in. For example, in many Samsung models, the Standby option is installed. this is a standby mode, when it is on, a red light on the outer panel of the unit is on. Please note that it is not recommended to leave the television receiver in this mode for a long time, since when it appears to be off, all the power supply circuits are under high voltage and wear out.
If there is a sudden power surge, the equipment may burn out, after which the receiver stops starting.
To prevent such a malfunction, the unit must be turned off with a button from the panel. this will significantly reduce the risk of electronics burnout. If you observe an indication response, but the TV does not respond to commands coming from the remote control, then try turning on the unit through the panel.
If after that the picture is loaded, then most likely the malfunction concerns the remote control. On some Samsung TVs, a clicking sound is heard when the lock is activated. You cannot fix such a failure with your own hands, the only reasonable way out in this situation is to contact the service center.
If the LED button changes its color from red to green and vice versa, but the TV does not start, most likely, the control unit generated a signal to turn on the device and sent it to all the necessary modules for execution.
But if any of them fails, then the command will not be executed. For example, when there is an interruption in the operation of the power supply, the television receiver will not be able to enter the desired functional mode. In this case, the processor will not receive information from it about normal operation, so it will immediately send a feedback signal to cancel the device turning on. thereby returning it back to sleep mode. Such blinking can last for a long time until you eliminate the root cause of the problem: repair the inverter, replace the transistor, recycle the power supply completely, or fix some other malfunction.
If the indicator of the television panel is lit in green, nevertheless, the equipment does not even think to start, then this situation can rather be called ambiguous. Here you need an experienced craftsman who, with the help of professional equipment, can check the functionality of the electronic board, measure the voltage supplied to it, and also examine the start signal, backlight and many other problems.
If the light comes on, giving a signal that it is ready to work, but no commands are received from the main board, and the device does not respond to the remote control and does not respond to the panel buttons, then with a high degree of probability you are dealing with software malfunctions. securing.
In this case, only a software update and a complete flashing can return normal operation in the motherboard.
If it takes too long to turn on the TV receiver, this directly indicates that one of the units of the unit is out of order. For Samsung LCD TVs and CRT models, the reasons for this failure can vary greatly. It will be difficult to identify them without the necessary tools, skills and knowledge.
Turns on and off immediately
Why does Samsung screen turn on and off by itself? Turning on and off the TV is carried out via the remote control. If the TV does not respond to manipulations with the remote control, then the problem is in it. One of the reasons the batteries are dead, try replacing them.
The second reason may be hiding in operating systems. Like any computer, modern TVs run on an operating system. If the OS malfunctions, then independently turning on and off the TV is inevitable, for this solution, contact a specialist, the problem will be solved immediately by reinstalling and updating the OS.
You turned on the TV, it turned on and then turned off. The problem may be hiding in the power supply or a weak connection. Also, due to a sudden power surge, TV may experience such a failure. Use the indicator to check the condition of the outlet and the voltage.
If after installing a new TV, you turned it on and after a while it turned off, then check the settings. Perhaps a timer is set in the settings to turn off the TV on its own. Some models have certain default settings. when the signal is unstable, the TV turns off. Change your settings and the problem is resolved.
The screen may black out unexpectedly during playback. This can be due to several reasons. But first of all, check if the TV indicator responds to the remote control. Click on the menu. If it appears, then look for the reason in another.
Here are some of the most common reasons why the TV turns off on its own.
Today TV devices with LCD or plasma screens have become thinner, lighter, thus easily exposed to external mechanical influences that can damage the screen itself. It can be easily dropped from the stand onto the floor; in case of poor attachment to the wall, the TV may fall. If there are small children in the house, playing with a toy and unaware of the fragility of the screen, they can knock on it. In any of the above cases, the screen suffers.
Then questions arise, is it possible to fix a plasma TV after a shock and the plasma TV needs to be repaired after a fall.
Important! A plasma TV screen is a collection of a large number of cells, consisting of xenon and neon. These cells are covered with phosphors. This is a complex “organism”, which is placed between two glass planes.
If the screen is damaged, the image quality suffers. If the screen is cracked, you can forget a good picture from the TV screen. It is impossible to repair a cracked plasma TV screen yourself at home. Because the matrix can be replaced qualitatively only in a service center. Plasma TV matrix repair can only be entrusted to a service center or a good workshop. It is worth consulting in advance at the service center how much this type of repair will cost.
In connection with such a breakdown, the price of repairs can reach the amount for which you can purchase a new TV. Repairs vary by country of assembly and part manufacturer. If you want to understand better, then study where LG TVs are made and assembled. A broken screen can only be replaced with a screen from the same manufacturer.
You are the owner of a home theater and the sound quality does not depend on plasma, then in case of its mechanical damage, the right decision would be to buy a new LCD or plasma TV. Because how long the repair will take and whether the necessary plasma panel is available in the service center and the price issue plays a big role.
We invite all owners of LCD or LED TV to take advantage of our recommendations, which will eliminate (or minimize) the likelihood of such defects.
Do not try to replace the display or other components on your own. With unskilled intervention in the design of the television receiver, there is a risk of bringing the equipment to a state of complete unsuitability for repair. It is better to call the operator of the A-Iceberg SC, describe the problem and call the master at home.
Another problem that users of modern LCD TVs face is the image or the display darkens, why this happens. It happens that the image is just blurry, and we start looking for the reason, reading the instructions from the manufacturer, articles on the Internet. In fact, the problem lies either in the settings or in the incorrect connection of the antenna, namely the use of the wrong input.
Recommended screen brightness from 60-80% for comfortable viewing of the image with eyes. If we constantly increase the brightness, then we increase the load on the LED lamps, on which the brightness of the plasma TV screen depends. Also, the LED problem is indicated by a darker screen display.
To determine if LED bulbs are really the cause, arm yourself with a regular flashlight or turn it on on your smartphone and direct a beam of light onto the screen. And you will see the silhouettes of the broadcasting image on a dark background.
This malfunction can be repaired by hand. You can use Internet resources to learn how to repair a burned-out light bulb on a Samsung plasma TV and alji with your own hands, namely, watch video tutorials in which they show in detail step by step and tell you how to properly disassemble the TV so as not to damage where the LEDs are located. because each manufacturer places them differently. Before repairing, study the TV structure diagram so as not to damage matrices, boards, wires and fragile connections during the process.
Contact a technician to repair your TV
To replace it yourself, you will need a hair dryer, a screwdriver, a circuit, and a work surface. You can watch the video on free resources on how to properly remove the back cover and find a faulty light bulb. Visually, you can determine which light bulb has burned out, there will be traces of brown around it. To remove it, turn on the hair dryer at the minimum speed and warm up the glue so that the lamp can be removed freely, put a new lamp in its place. And check if there is voltage, if everything is done correctly, then the image will appear.
Also, the image may disappear due to poor signal quality. Some models are equipped with a weak tuner. And a good signal is the key to high-quality TV viewing. Check the antenna connector for loose connections. If the problem is in the antenna, then just replace it.
A damaged matrix should not be ruled out. If they themselves could not determine the cause and eliminate the problem, then professionals will always come to the rescue.
How to visually tell if a screen is broken?
Screen damage will not always be expressed as a visible crack (s). In addition, the TV after damage can work normally for some time.
You can suspect damage to the screen by noticing distortion of colors, clouding in some area of the screen, the appearance of stripes, a black oily trail. Visual inspection will also help: the crack may not be visible from one angle, but will become noticeable if you look at the screen from a different angle.
Is it possible to fix / replace a broken TV screen?
The screen of a modern TV is a monoblock assembled at a high-precision robotic enterprise. The complexity of the assembly, soldering, and drying processes makes it impossible to disassemble the screen in order to replace any element. It is only possible to replace the entire screen.
But in this case, the cost of a new screen, materials and work will be comparable in price to the purchase of a new TV, which makes the work of replacing a broken TV screen unprofitable. In addition, replacing the screen is not possible at home and requires transporting the TV with special precautions.
One of the possible solutions for a plasma TV is that there is a possibility that if damaged, there was no gas leak and there is no need to replace the matrix. You can fix the problem by reconfiguring your TV. However, the specialist will be able to assess the severity of the breakdown and possible solutions to the problem only on site.
If the TV screen is cracked, then even with minor damage, stripes, color distortions and other image imperfections will be visible on the display. There are several reasons for the malfunction, but usually they consist in mechanical damage. You will not be able to fix the problem yourself, so try to call a service engineer.
The masters of the A-Iceberg SC repair TVs of all popular brands (from inexpensive LCD panels Toshiba, Supra, Philips to the TOP models of LG, SONY, Samsung). Diagnostics and repairs are carried out at home in the presence of the client (without taking the equipment to the workshop). To call a telemaster for a specific time, call 8 (495) 213-11-90 from 7:00 to 23:00 on any day of the week (seven days a week), or leave an online application on the website indicating contacts for feedback.
Plasma TV malfunctions and their elimination
Like any technology, TV devices tend to break down, regardless of their brand and model. Let’s first figure out which malfunctions are the most common:
- the image is included in whole or in part;
- there is sound, but there is no picture;
- independently turns on and off;
- damage to the screen by external physical impact;
- problems with the remote control;
- spots appear on the screen.
In this video, we will consider repairing an LG TV:
Like everything that happens, there are reasons for plasma device malfunctions, which lead to unexpected breakdowns. Most often, the cause of the breakdown lies in the malfunction of the LED circuit or lamp, poor contact of the power supply, inoperative matrix. No matter how elementary it sounds, ordinary dust can lead to a malfunction of the TV.
Attention! To repair faults, it is important to understand circuits, electronics and be able to work with tools. Without special knowledge about the plasma TV device, do not disassemble it yourself, but call the master or contact the service center.
The appearance of spots on the plasma TV monitor may indicate a problem with the installed card. If a light (white) spot spreads all over the screen, then we will look in the TV “MAIN-board”.
What to do with a broken TV screen
The screen of a plasma or LCD panel is the most vulnerable spot. The matrix responsible for image reproduction may suffer from moisture or mechanical stress. What to do when the TV screen is “broken”, consider further.
How to protect the device from accidental damage
If your TV is not equipped with a display protection from accidental mechanical stress, you can take care of this yourself. Acrylic protective screens are produced separately, and you can purchase a product of a suitable diagonal to install on an expensive TV panel.
The option of installing a protective glass on the TV panel will not affect the image quality, but at the same time it will protect the matrix from moisture, dust and other mechanical influences. True, such protection will not protect from damage when falling. To prevent the TV from falling, it is recommended to properly fix it on the wall using a special bracket.
If the plasma panel is broken
For a plasma TV, the screen is a monoblock of the following parts.
- Two high-quality glass screens with a thickness of no more than 2 mm.
- The matrix is a cellular structure filled with a mixture of xenon and neon, and is located between glass screens.
- A layer of phosphor, to which a current flows through special conductors, which causes a glow.
The principle of operation of the structure is that light of different intensity, passing through the cells with illuminated gas, forms an image. Any mechanical impact can violate the integrity of the matrix, which affects the quality of the image or its availability.
If, when the panel is damaged, there is an image, but with various artifacts, you should contact the service center for advice. There is a small chance that the problem with a broken TV can be solved by reconfiguring the matrix. Such repair is possible if there is no gas leakage from the matrix cells. Otherwise, the panel screen cannot be repaired after impact. To repair a broken TV, you will need to replace the entire plasma screen.
If the LCD receiver is broken
LCD screens and LED panels are also made in monoblock format. They are a matrix on liquid crystals with RGB filters, placed between two thin glass panels and a backlight, the intensity of which is regulated by supplying current through a special conductive loop. The slightest crack in the inner or outer glass will damage the connections in the crystal matrix, which means that the screen is broken.
The restoration of the most complex structure of the LCD TV matrix due to the complexity of the production of TV screens is not provided. Also, spare parts are not produced, and there are no schemes for repairing damaged screens. There is no way to fix a broken LCD TV screen.
Repairing an LCD TV screen means installing a new matrix in place of the damaged structure, or replacing the protective glass. Such work is carried out only in a specialized workshop. As with plasma. display replacement is costly.
How can a broken TV be used?
If, due to the fault of households or pets, the TV still crashed, there is no need to rush to throw the device away as unnecessary. Commercial workshops redeem broken equipment for spare parts. In addition, an interesting lamp, color music and even an infrared heater can be made from a broken LCD TV. Manufacturing technology can be found on the Internet.
