The matrix, as a rule, is subject to any damage very often. It could be broken by children, the TV might fall, or water might somehow get on the screen. If stripes or some stains appear on the screen itself, it will not be entirely easy to remove them. The best thing to do is simply replace the matrix on your TV. This process cannot be called easy; the part itself is very expensive, since it is the main and important part of the TV.
Replacing a TV matrix mainly occurs due to careless handling or incorrect operation rules. Without a matrix, a TV, as a rule, will not work. The repair process itself depends on the complexity of its breakdown.
If water gets on the monitor, such repairs will take a long time, as they require a careful approach. You won’t be able to do the repairs yourself, because this is a very painstaking job and only a specially trained master can handle it.
Replacing the screen with a new one can be done if the matrix has fallen due to mechanical damage. That is, if damage occurred due to an impact and it burst or scratches appeared on the monitor. Then you can cope with such a task with your own hands, you just need to choose the right type of matrix. Since each TV display requires an individual type, with its own main features.
The main signs indicating a matrix failure:
- The usual image was replaced by vertical stripes of different colors;
- Smudges and horizontal stripes have formed;
- Dark circles appeared on the monitor;
- Small spots of different colors appeared on the screen;
- The picture began to disappear partially or entirely.
If you notice even one sign, then you definitely need to make repairs. Restore the matrix if it leaks or replace it with a new one. A broken matrix does not look aesthetically pleasing on a plasma TV, so it must be replaced; without it, the device simply will not work.
Repairing a TV matrix cable: step-by-step instructions
Today, ice televisions and plasmas are not a novelty. You can find one of these in almost every home, office or on the corner of a large supermarket. Such devices have specific breakdowns that require special repairs. All well-known manufacturers: Samsung, Philips, Sony, Toshiba provide their own warranty period, so the service center must provide its free services.
LCD TVs need to be repaired when the microcircuit, cable, screen fails, or problems arise with its backlight. All this indicates a matrix failure. You can repair it manually or contact a service center.
It may be impossible to repair the matrix because the screen is cracked or completely broken. A broken matrix cannot be repaired; restoring it makes no sense. Therefore, it just needs to be replaced. But if the matrix cable is faulty, then you can fix it yourself, using the master class lessons.
Loop repair instructions:
- Disassemble the TV case;
- Identify a damaged cable that needs to be repaired;
- Carefully you need to disconnect the cable from the matrix, do not wobble it, but pull it out straight;
- Clean damaged contacts and degrease them;
- Solder the contact;
- Place the cable in place;
- Assemble the device.
This process requires extreme precision and accuracy so as not to damage the remaining thin cables. At the end of the work, you must check the TV and make sure that your actions are correct. To avoid doing such important work, it will be easier to replace the damaged cable with a new one.
Matrix for Samsung TV: step-by-step instructions for replacing it
Each manufacturer uses an individual type of matrix for their TVs. There are three types of matrices: TN, IPS and VA. Most companies use VA and IPS matrices, since they are advanced models. They have excellent quality images, excellent color palette and good viewing angle.
However, these models are also prone to breakdowns. Damage to the matrix occurs due to improper and careless handling of the equipment. The screen needs to be looked after regularly, its surface should be cleaned with a soft cloth, and no detergents or disinfectants should be used.
The well-known company Samsung uses most types of matrix in its production. One of them is the ltf320ap08 type. If it does break, then you need to try to restore or replace it. First, we purchase the correct matrix that is suitable specifically for your model, and then we begin the repair.
Step-by-step matrix replacement:
- Disassemble the TV. You need to separate the front panel of the TV from the back. The housing is connected with self-tapping screws that need to be unscrewed with a screwdriver.
- Place the matrix on a soft surface.
- Disable all loops. This must be done very carefully so as not to damage the special fastenings of the cable. In this case, adhesive tape is applied to the surface of the joints.
- Remove the matrix.
- Connect a new element.
- Reassemble the device body in reverse order.
After all the work done, you definitely need to coordinate the matrix with the TV using the remote control. If this does not happen, you need to make certain settings by entering the TV menu.
Modern matrix for LG TV: minor differences
Before replacing the screen on well-known TVs manufacturers Samsung, Philips and LG, first let’s find out what a matrix is. This is a glass surface that consists of a large number of pixels. They, in turn, can change the color and brightness of the image, depending on the influence of various signals from the external environment.
The Matrix is the main element of TV. Each TV manufacturer uses its own type of matrix. For example, LG TVs use IPS matrices. This type does an excellent job of providing image clarity and contrast.
Today, LG TVs are very popular and are the best-selling model. However, incorrect handling of the TV can lead to its breakdown.
Main faults:
- Screen cracked;
- The microcircuit has failed;
- Problem with the cable;
- Pixels have lost their functionality;
- The LED backlights do not light up.
Some faults can be fixed on your own, but more complex faults ( broken screen) require specialist help. Repairing LG TVs is practically no different from other devices. There are minor differences that can only be detected in the design of the model itself.
Correctly replacing the matrix on a TV (video)
Without a matrix, the TV will not work, since it is its basic component. Replacing the matrix is not an easy task. If you are not confident in your abilities, it is better to seek help from specialists or a service center. They will help identify the breakdown and replace failed parts.
Let’s say right away that changing the matrix on a TV is not entirely easy. But without it, the TV will not show, so you will either have to change it yourself, or contact a specialist, or buy a new source of information and entertainment.
Causes and signs of failure
The matrix is perhaps the most susceptible part of the TV to damage. Children often break it, liquid gets on it, and the TV can fall directly onto the screen. If you find that some spots or streaks have appeared on the screen, it will be very difficult to remove them. Most likely, the matrix will need to be replaced. In addition to the fact that the repair itself cannot be called simple, a new part will be quite expensive. In fact, it is the most expensive part of a TV.
When moving the TV to a new location, you need to ensure maximum security for the monitor. Any impact can cause poor-quality images, and then a replacement will be needed. Here are the signs by which you can understand that something is wrong with the matrix:
- colored vertical stripes appear instead of the image;
- thin horizontal stripes, streaks, and stains appear;
- black circles are visible on the screen;
- dark and light dots have formed on the screen that do not disappear;
- the image has completely or partially disappeared.
Sometimes when liquid gets on the contacts of the matrix, it can be restored. This repair is very painstaking, takes a lot of time, and requires certain knowledge and dexterity. In case of mechanical damage, repair can only consist of replacement.
Replacement part or new TV?
By calculating all the costs, you can decide whether you are satisfied with a replacement or whether it is better to buy new TV. Some service centers buy non-working household appliances for a modest price or replace them with a surcharge for new ones.
If you still want to make repairs, then you need to remember that each TV model has an individual matrix. Sometimes you have to order it and wait some time for delivery. Matrices are not sold in the public domain, since they are a very fragile and expensive product, and, as already mentioned, they are individual.
DIY repair
If you decide to repair the matrix yourself, then you must adhere to the following rules.
- First, find and order a new matrix, focusing on the bottom ones, which are indicated on the rear plate of the panel. You can contact service centers where replacing the matrix is common, and ask them about the required model.
- When disassembling the panel, place it on something soft (for example, a piece of thick cardboard) with the screen facing down and tighten all the screws and screws. Then turn it over and detach the front part of the case. It is attached with latches.
- Before removing the matrix, the cable and wires are disconnected from it. Sometimes cleaning the cable with an eraser helps get rid of minor defects, but if the damage is mechanical, this will not help.
- Carefully insert the new matrix, connect the power cable and cable to it and turn it on to make sure its quality. The screen should glow and there should be no even the smallest defects on it.
- Only then close it back panel and screw it on.
At first glance, it seems that replacement is simple, but the matrix and all its connectors must be handled very carefully. If you do it carelessly, you can ruin your new part, which will ultimately hit your wallet hard.
It happens that after complete assembly the image is not displayed on the screen. This means that the operation of the new matrix must be coordinated with the TV control modules. You can make the settings through the menu. Setup information can be found in the user manual.
The liquid crystal panel is the key and most expensive component of any TV. To repair this component if it breaks, the user can contact a specialized workshop or rely on his own efforts. Having chosen the second option, the TV owner must be prepared for a number of difficulties that will inevitably arise when performing this procedure. Our team will help make the whole process easier detailed instructions, where the repair of the LCD matrix of a TV is discussed in detail.
Basic problems
Let us immediately note that in this material we will not talk about defects of LED backlighting, such as its flickering, unevenness, as well as partial or complete absence. When considering damage and malfunctions, we will only talk about the glass of the matrix itself, where the picture is formed. For convenience, we have divided all defects into several types, for which repair tips will be written, if possible.
Physical damage
In most cases, the LCD panel fails after impacts on the screen, falling of the device and other similar factors. Unlike old TVs, modern matrices cannot withstand some mechanical loads so well. Even thrown by a child soft toy with a glass eye into the TV screen can end badly for the latter.
If the matrix in your TV breaks due to excessive physical impact, then it cannot be restored and the LCD panel must be replaced.
Image distortion
Factory defects are also not uncommon. It can appear either immediately after purchasing the TV or after some time of using the device. This breakdown can be so diverse that it can easily be divided into several categories:
- vertical stripes on the screen;
- absence of a picture or part of it;
- pillars in the image;
- “fading” or “braking” of the frame;
- illuminated areas on the matrix changing their position;
- color distortion and so on.
There can be many reasons for this malfunction. Usually the problem lies in flexible cables integrated into the glass of the matrix and control chips.
In most cases, this problem can be resolved by contacting your manufacturer's service center. You should not try to fix a problem with a new TV on your own, because you will be denied warranty service. Moreover, even if the defect is caused by a manufacturing defect, which involves replacing the device with a new one, you will also not be able to receive compensation after independent intervention.
The appearance of spots in the picture
Another common matrix failure is various spots of oval, round or any arbitrary shape. They appear due to defects in the matrix glass or due to a damaged polarization layer.
Wear of these elements can be caused not only by manufacturing defects, but also by violation of transportation rules, storage standards and even operating requirements. If such spots appear on the display of your TV, then in this case the only thing possible solution– matrix replacement.
Unskilled intervention
Although it's not common reason display failure, but it should also be mentioned. Problems with the matrix can also appear after the screen itself, the screen, or other components of the TV. In this case, torn cables, cracks in the corners of the screen, chips and other damage may appear. Of course, you can repair the LCD matrix of a TV yourself, but for this it is important not only to study the issue, but also to be careful. Remember that repairing any equipment also includes proper disassembly and assembly.
Disassembling the device and fixing the problem
It is very important to carry out the disassembly procedure very carefully so as not to damage other components of the device and not make repairing the TV prohibitively expensive. It is especially important to be careful when removing the screen itself, because breaking the cable leading to it will require, as in the case of physical destruction, a complete replacement of the matrix. Alas, such repairs cannot always be called a profitable solution, because taking into account its cost, it would be much more reasonable to purchase a new model. The exact price depends on the features of the matrix, the presence of other defects, as well as the availability of a new screen for sale. Before disassembling the TV, you need to prepare enough space on a large table. The space should be at least 2.5-3 times larger than the dimensions of the device. This is necessary for conveniently rearranging different elements, such as screws, boards, as well as the matrix itself. It is also recommended to place a piece of cardboard or thick soft cloth on the place where all procedures will be carried out, which will protect the display from scratches, chips and other damage.
Then the TV is placed on the table with the screen down and the screws holding the cover are unscrewed around the perimeter of the case. After this, it should be easy to remove, but sometimes you will also need to find an additional lock and set it in a different position. After completing this procedure, turn the TV over and remove the front frame from the latches, which will help you gain access to the matrix. In some cases, you can access the insides of the TV not from the back, but from the front, which depends on the design of the device.
If you accidentally spilled a drink (coffee, soda, etc.) on the TV, after which image artifacts appeared on the screen, then sometimes to restore the TV’s functionality it is enough to clean the cables leading to the display. In this case, in addition to screwdrivers for disassembly, you only need a regular eraser. However, this method will not help with physical damage. The video tutorial will tell you how to properly clean the cable:
Replacing the matrix
When the case is completely removed, you will see in front of you a metal matrix frame on which all the electronics and cables connected to them are attached.
The latter must be disconnected very carefully to prevent breakage. Replacing the LCD matrix on a TV is a fragile process. Then unscrew all the screws that secure motherboard, power supply and other components.
Owl! In order not to get confused in the subsequent assembly, you can first photograph the placement of all elements of the TV.
After all components of the model are disconnected from the matrix, you need to unpack new screen and fasten all the boards, cables and speakers on it in reverse order. Once all the modules are in place, you can begin installing the frame and cover in place, as well as subsequently checking the functionality of the device. The video explains this process in sufficient detail:
Conclusion
Self-repairing the LCD matrix of a TV is a fairly simple procedure, in which the most important thing is not previously acquired skills, but caution and strict adherence to instructions. If you have minimal experience in disassembling equipment, then you can replace the screen on your TV without any problems. But for more serious damage, you should make sure that you are able to fix the identified problem, and also make sure that such repairs are advisable. Some types of damage will cost TV owners 60-80% of the cost of a brand new model, so evaluate the economic benefit. If, from a financial point of view, repair does not seem an attractive solution, then you should take the TV to a workshop for spare parts, earning some money for it.
Owners of TVs with LCD and plasma screens often face the question of whether it is advisable to replace a broken matrix. High cost of work in service center pushes to search alternative options– independently replacing or purchasing a new TV. It's worth figuring out which is better.
Signs of a broken matrix on a TV
General sign The fact that the matrix in the TV has become unusable is a violation of the normal transmission of images to the screen. It may appear as follows:
- Spots of round or oval shape are black.
- Burnout of individual pixels, which appears as light or dark spots on the TV screen.
- Vertical stripes of different colors.
- Horizontal gray stains and stripes.
Signs such as: darkening along the edges of the screen (or a separate part of it), complete absence of an image (black screen), blinking, white noise, may indicate the failure of not the entire matrix, but only a separate part of it, for example, the backlight. That is why it is important to make replacements and repairs at a service center - only there they can determine the cause of defects with 100% accuracy. The cost of work depends on the TV model, the availability of ready-made spare parts, and whether they are produced by the manufacturer itself.
When the outer glass of a plasma screen cracks as a result of physical impact, the matrix itself is damaged. The gas mixture contained in it comes out, and numerous noises appear on the screen. In this case, only replacing the matrix can solve the problem, since its repair is impossible.
The only advantage self-replacement matrix on TV is saving cash. Since repairs at a service center cost 75-85% of the cost of the equipment itself. Self-searching for a screen on the Internet helps you find the most profitable option, and you don’t have to pay yourself for the work.
Preparing to replace the matrix on the TV
Before replacing the matrix on the TV, you need to perform a number of preparatory measures:
- Buy a new matrix. Choose suitable option You can do this on specialized Internet sites or at a service center that repairs this type of equipment. You need to start from the data that is indicated in the technical documentation for the TV.
- Buy a protective screen. To prevent possible breakdowns in the future, use a new matrix plasma TV It is better to buy a protective acrylic screen.
- Prepare workplace. To avoid accidentally damaging the LCD screen further, the work area must be covered with something soft, for example, thick cardboard or a blanket.
- Collect required set tools and materials. This includes a set of screwdrivers with different types profile, tweezers for penetrating hard-to-reach places and a thin metal plate.
Instructions for replacing the matrix on a TV
Step 1. Disconnect the wires and cable from the TV. Accordingly, if the TV is mounted on a bracket, then remove it from it. Move equipment to the workplace.
Step 2: Separate the front of the TV from the back. Using screwdrivers, unscrew the screws holding the housing together. Place the matrix face down on a soft surface (thick cardboard), use a plate prepared in advance (or any convenient device (not a knife!)) to unlock the latches.
Some TV models may use screw connections instead of plastic fasteners. Use the appropriate tool to work with them.
Step 3. Remove the old matrix. Having first disconnected the power supply wire and the signal cable from it. This must be done very carefully, preferably study in detail the mechanism of fastening the cable in advance. During assembly, the junction of the cable and the matrix is additionally taped with tape; it must be removed in such a way as not to damage fragile elements of the equipment.
Step 4. Prepare the new matrix for installation. Wipe its edges with a damp alcohol wipe and install metal fasteners.
Step 5. Install a new matrix. Connect the signal cable and power cable to it. Check functionality.
Step 6. Reassemble the TV case in reverse order. Install a protective acrylic screen.
Step 7. Coordinate the new matrix with the TV control module. Sometimes, after replacing the matrix, the image is still not transmitted to the screen; this may be due to inconsistency between the new screen and the control module. The necessary changes are made through the TV menu; more details about this can be found in the documentation accompanying the equipment.
Video instructions for replacing the matrix
Replacing the matrix on a TV in a service center is carried out in a short time and using all the necessary tools. If it is not possible to contact specialists, then following step by step instructions You can do this work yourself. In general, it takes 0.5-1.5 hours.
When it comes to replacing a broken screen, laptop owners often have questions about their compatibility. This article will focus on presenting the user with the necessary technical information for competent selection of an alternative screen from the many available on the market.
So, monitors have different diagonal sizes, measured in inches, operating resolution, matrix type, type of backlight, location and types of interface connector.
Information on the interchangeability of some types of matrices can be found in the table.
