The LCD TV screen is broken, is it possible to repair it and how much will it cost? How quickly can it be repaired and is it necessary to replace the matrix?

Long gone are the days of CRT televisions - they have been replaced by LCD screens. Thanks to this technology, the image is very clear and beautiful, in the smallest detail. Such devices look stylish and appropriate in the interiors of houses, and are provided by TV receivers. They are characterized by light weight and thinness, easy transportation.

There are two sides to every coin: modern TVs are very fragile, so operation must be very careful. Breakdowns often occur and a web of cracks appears on the screen - is repair possible in this case?

What does the screen consist of?

The main component is the matrix. It contains a huge number of particles that are filled with xenon and neon. The matrix is framed around the perimeter with semiconductors. Phosphors begin to glow when UV is created - a glow created by an electric current that passes through a gas medium. This process causes the cell to glow in the desired color. Together, tens of hundreds of cells create the image that the TV shows.

The entire screen structure is located in a small space between two planes, which are made of durable glass. To understand whether the LCD screen is broken, you need to understand how the breakdown occurred.

Damage to the cable and glass leads to the need to completely change the matrix.

In order to place an order for TV repair or monitor repair, you must provide basic information about your device: its name and model, diagonal, and what the problem is. You can always place an order by phone or simply by sending an application electronically.

The prices for repairing LED TVs will depend on the screen diagonal of your TV (monitor). The diagonal can be clarified by the hardware model (the first digits are the matrix size in inches). Or simply measure the screen diagonally with a tape measure. You will get the result in centimeters, and dividing the result by 2.54 (1″ = 2.54 cm) - in inches.

Causes of screen breakdowns

Is it possible to repair a TV if the screen is broken or cracked? Let's consider several reasons for the problem:

the TV fell, was hit with a heavy object, was filled with liquid, or suffered other mechanical damage;
microcircuits that are responsible for the functionality of liquid crystals are broken;
pixels have burned out due to non-mechanical reasons;
The backlight has failed.

If the backlight is simply broken, there is hope that the LCD screen can be safely repaired. Especially if it is an outdated model with halogen lamps, which are easy to change. But if LED backlight technology (LED type) is used, repairs are possible based on the manufacturer’s company. For example, many produce models that have built-in LEDs, which are located in cables that cannot be installed. In this case, the situation cannot be corrected.

Damage to the system board

I would like to add that if colored stripes appear on the monitor screen, this does not mean that it is the monitor that is broken. The reason may also be in the motherboard. Therefore, if there is no visible damage on the screen, try connecting it to another computer. If it works, it means the system board is damaged, and we take the system unit to the master.

Most likely, in this case you will have to buy a new motherboard. If one like yours is no longer on sale (it has been discontinued), then you will have to buy a processor, operational boards (optional) and so on along with the motherboard.

Cracks on the display

Is it possible to replace the display if cracks appear on it? The fact is that cracks violate the very integrity of the matrix, and a mixture of gases leaks from the container under the glass. This kind of problem cannot be repaired; you just have to buy and install a new matrix.

Many people prefer to buy a new TV, since the cost of the matrix is equivalent to a new device.

It is easier to purchase a new plasma panel if it is a home theater component and does not have audio output devices. Here you just need to replace the broken panel with a new one. If a large multifunctional plasma TV is broken, you should think about repairs. Before choosing a new model, consult with sellers about the quality and place of assembly of the device - operation depends on this.

Where can I submit it?

If you need to hand over your TV for recycling, you need to figure out how to do it. There are several options to get rid of unnecessary equipment without harming the environment.

Sell

If the device still works, it needs to be sold. To do this, they use online advertising platforms. For an additional fee, the listing will stand out among others for a while, attracting more potential buyers.

It is recommended to take several photographs, especially when the device is turned on. They are posted along with the ad.

Used TVs are needed by owners of garages, apartments intended for rent, and summer cottages.

Give it to a pawnshop

If the device is in good condition, it is taken to a pawnshop. The main condition is the availability of documents for the TV. A pawnshop representative evaluates their value and offers a certain compensation, which the owner can receive immediately.

Take it to a scrap metal collection point

This is a good way to get rid of junk, suitable for Soviet television receivers. Such devices contain rare and valuable metals. Therefore, many items accept them for later analysis. The disadvantage of this method is that the owner will not receive a decent payment for a working TV.

Take it to a thrift store

Some consignment stores buy old household appliances for resale. The store evaluates the condition of the equipment and determines the sale amount. If the device is purchased within a certain period of time, the previous owner receives a percentage of the income.

Services of specialized companies

Many cities have companies that recycle household appliances. All you have to do is call our employees to your home and they will remove your old TV. But payment will save you from searching for other ways to dispose of the device.

Promotions when purchasing new equipment

Large retail chains often hold similar promotions. For returning your old TV they offer a discount on a new one. This recycling program benefits both customers and stores.

The “Total Recycling” program is organized annually by the Eldorado chain. For an old TV, participants of the promotion are given a discount on a new one. Removal of the old device and delivery of the new one is carried out at the expense of the store. Similar programs that allow you to get rid of junk and save money operate on the M-video and MediaMarkt networks.

For free

If a working TV is no longer needed, it can be given to people in need. Such assistance is appropriate for low-income and large families, single elderly people, and geriatric institutions. You can give the TV to acquaintances or friends.

Replacing a cracked display yourself

If you decide to fix the problem yourself, use the general recommendations. Please read the device installation instructions first. So, how to replace:

disconnect the TV from the power supply, remove all cables from the outside;
place the device on a soft and flat surface;
unscrew the screws;
remove the frame on the damaged screen;
remove cables and wires from the inside, remove the screen;
mount the new panel and connect cables and wires. Turn on the power.

As you can see, it’s not difficult to do everything yourself. The main thing is that changing the screen does not cost you more than buying a new plasma.

Is it possible to change the matrix?

First of all, pay attention to the manufacturer of the device, the amount of damage and the price. If you purchased the device a long time ago, perhaps they no longer produce a matrix for it. If this is the case, you will have to buy a new TV. You may be able to find a replacement part in service centers or at disassembly sites with a quality certificate and warranty. If you have a device with a large set of functions, it is worth trying to repair it. You may just need to reconfigure the matrix - if all the gas has not yet completely come out of it, but stripes appear on the screen (horizontal or vertical), the situation can be corrected.

It is possible to repair this part of the TV, but the repair must be done by a professional. It is necessary to place the device in a vertical position, do not tilt it, it is advisable to fix it firmly or ask someone to hold it. It is recommended to transport large plasma in a spacious car so as not to spoil it.

Exclusive interior items

If you simply take out the kinescope, insert the mirror inside the housing and install a backlight on the back wall, you will get a minibar. We attach the mirrors with special “glass” glue, and make the lighting from sticky spotlights powered by batteries. All that remains is to supply alcoholic drinks and a container with cocktail straws.

And to make an aquarium, you need to remove the back cover, remove the electrical parts, and free the inside. We leave the buttons for compressor air. We insert the aquarium so that there is room for lighting and algae.

When disassembling, be careful with the beam tube. Additionally, make a cover and attach it to the panel

Pour water into the aquarium and add the fish after three days (this time is enough for the water to settle).

In the same way, the TV turns into a pet bed. In this case, the inner part should be covered with soft material, and a mattress should be laid underneath. It is advisable to varnish and decorate external surfaces.

The case, free of “stuffing”, is also suitable for storing books. Surfaces need to be cleaned and covered with sticky wallpaper. We attach loops to the back wall for hanging. If the case is large, we divide it horizontally with an additional shelf.

A table made from an old TV? It's simple! It is important that the model has a flat screen

Two or three cases, painted in different colors and placed on top of each other, will serve as an original shelving unit. It makes more sense to fasten them together for structural strength. And screw the legs from below.

Why not make a dollhouse or mini-room? Scraps of fabric and pieces of wood will make you feel like a real designer. And the gift for the child will be magical.

How many interesting objects can you turn an old TV into if you use your ingenuity! Sometimes you will need sandpaper, paint, varnish and other available tools and materials. A little effort - and a stylish accessory or useful thing is ready.

Prevention of cracks and recommendations for safe operation

If you have children in the house, and you are afraid of touching or knocking over the TV, take simple steps to ensure reliable operation. For example, you can install an acrylic screen to protect the LCD - it makes the screen thicker without compromising image quality. Also, you can be sure that your TV will not suffer from spilled tea or impacts or scratches. This acrylic overlay also protects the matrix from dust accumulation.

A serious risk of injury arises from the possibility of falls. Buy a hanging bracket that hangs from the ceiling. Of course, these are unforeseen financial costs, but it’s easier to secure a device than to buy a new one.

Proper operation of household appliances involves malfunctions, cracks and matrix breakage. Install the device on a flat surface or bracket, wipe off dust (without using aggressive household chemicals). Discuss behavior near the TV with your child - active games can lead to broken screens, falls and cracks.

If the matrix in your TV is faulty, first of all you should contact us to find out the availability or replacement of the matrix, as well as the cost and delivery time of the matrix. Give us a call.

Read for everyone, Important!

Before you call or about the cost of replacing the matrix, SO AS NOT TO WASTE YOUR AND OUR TIME, first find out the TV model, since there are many modifications of LCD, LED or LCD matrices, even within the same TV model. Thus, there are hundreds of items for each screen size. It is IMPOSSIBLE to provide you with information without a model.

How to determine the TV model?

THE MODEL NUMBER IS LOCATED ON A STICKER ON THE BACK OF THE TV. The so-called nameplate. Looks like that:

Do not try to read the model number from the box or documentation. Often the model number is partially reflected there, or is written for several models with different screen sizes at once. The information will be inaccurate, and you and I will simply waste time.

Or maybe they will “foist” a fake or “Chinese” matrix on my TV?

The manufacturer works hard to ensure that the user cannot easily resolve the issue of replacing a cracked screen.

Therefore, in nature Attention! THERE ARE NO UNIVERSAL MATRICES FOR ANY TV.

Each model has a clearly defined matrix model.

Moreover, even the same TV model, depending on the batch of goods, may have several different matrix variations. And these variations are not interchangeable. Depending on the type of matrix, the TV must be programmed for a specific matrix option.

Is it possible to restore a broken or cracked LCD, LED or LCD TV matrix?

We receive many calls every day asking us to restore or repair the screen (also known as the matrix, also known as the panel) after an impact. Definitely, if there was a hit on the screen, or pressure on the screen, or the TV fell, then 99.9% of the screen is broken. Even if cracks and fragments are invisible from the outside. The design of the matrix is such that the outside is covered with a special polarizing film, which does not allow cracks to be seen from the outside, and at the same time protects the user from injury. It is impossible to restore a matrix damaged in this way. In other words, it is no longer recreational. In this case, there is only one way - replacing the LCD, LED or LCD matrix with a whole one.

Is it possible to repair the matrix if water or other liquids get on it?

In some cases it is possible. When water gets on the electrical lines and contacts of the TV matrix, a galvanic reaction occurs. This triggers the processes of corrosion and dissolution of current-carrying tracks; short circuits also often occur in different circuits and this can ultimately lead to the destruction of chips on the matrix. If water gets on the screen and flows down it, or any other liquid gets inside the TV, even a small amount. Unplug the TV from the electrical outlet as quickly as possible and contact a matrix specialist. Don’t delay repairs; various liquids will sooner or later dissolve some of the matrix’s current-carrying paths. The faster the restoration is carried out correctly, the greater the chance of saving and restoring your screen.

What to do if the LCD, LED or LCD TV matrix is cracked or broken?

The matrix of an LCD, LED or LCD TV is very fragile and can easily be damaged or broken if pressed or hit. In some cases, the image on such a TV is partially or completely missing. It is impossible to restore a matrix damaged by pressure or impact. In this case, it is only possible to replace the LCD, LED or LCD matrix with a whole one.

How to change the matrix (display) of a TV?

You can replace your TV matrix with us. We do not recommend changing the matrix yourself, not because we are afraid of losing you as an installation client. This is simply done in order to prevent its damage due to incorrect, illiterate connection. Different types of matrices have a different supply voltage, the location of the power pins in the connectors also varies from type to type of matrix. Also, different matrix models use different positions of color bits in LVDS streams and other tricks invented by TV manufacturers. In this regard, you often have to resort to changing settings in the service menu of televisions, accessible only to specialists.

Ideas for a summer residence

It would seem, how can you use a TV in landscape design? In fact, this has its own interesting idea. By planting flowers in an old TV, designers thus create the effect of forgotten things. Such an object in the middle of a country house garden adds its own charm

Attracts attention, dilutes the abundance of nature with the subject of human activity

Bird feeder made from an old small TV,
Flowerpots
Shoe maker
A place to store various country small items.

Anything that can be made from an old TV, if you start implementing the idea with a creative impulse, can turn out to be very useful in everyday life. Therefore, before throwing it away, think maybe it’s worth making something useful and original out of it.

Bar

Not everyone has their own bar. If you have an old TV, this problem is easy to fix. The sequence of actions will be as follows:

take the TV, take out the kinescope and all the “stuffing” from it;
Remove the back cover too, replace it with a piece of plywood or fiberboard;
cover the inner walls with self-adhesive film, wallpaper, mirror panels or any other suitable materials, or paint them in a beautiful color;
if desired, glue battery-powered LED lighting strips inside the bar;
screw on a door or hinged lid, add shelves to make the bar more “advanced”;
fill the bar with alcohol, glasses, and straws for cocktails.

Minibar from TV

Lamp

An old tube TV makes original designer lamps. If you remove the screen and cover the body with a film that matches the rest of the interior, such an item will fit perfectly into the overall style. Instead of a screen, a transparent panel is installed, a light bulb with the appropriate connection is mounted inside, and then the lamp is placed in a convenient place.

Competent and rational use of old technology is a simple science. Sometimes it is enough to show a little imagination to get a lot of new, interesting things with minimal costs, but with maximum benefit.

Assembly

This circuit is simple: I plugged single-core wires directly into the “braid” from the power supply to the controller.
The “black and white” wire carries 16 volts through the switch and ground. White and blue wires (thrown by the installer at the telephone box) carry 5-volt signals to all three lines. Assembled and checked. If there is less flow to the DIM channel than the driver expects, the backlight will blink. With a voltmeter in one hand and a clock screwdriver in the other, I found the threshold at which everything calms down. In principle, it can be collected and used. But you can do it smoothly!

Brightness adjustment

Having read in the datasheet for the backlight chip what the controller expects from us on the DIM channel (I hoped that I would just get by with a resistor), I was disappointed - it is there waiting for a PWM signal, the duty cycle (part of the time when the signal is present) determines the brightness. On the same Ali, inexpensive PWM controllers were purchased: https://aliexpress.com/item/item/32953823579.html Even in the photo, an experienced eye would notice that their positive output is connected to the input, and the PWM is on the negative one, which me didn't suit me at all. What a pity that I realized this only after receiving the boards. But, having carefully measured the signal at the “negative” terminal, I was happy: it gave a normal PWM signal with the amplitude of the incoming voltage! Moreover, when turned off (and there is a twist with a click), the incoming voltage was supplied to the negative terminal! Those. I got a switchable brightness signal. This is what it looks like in real life:

As you can see, all the controls are located where the entrances used to be. For the on button, I widened the hole in the USB connector, and the brightness control fit into the coaxial input without adjustment. Everything was secured and insulated with pieces of fabric tape that used to hold the standard wires.

Personal Computer

Using a Raspberry Pi single-board computer (sold here), you can turn an old monitor into a full-fledged PC for about $50. All you need to do is connect your Raspberry Pi to your monitor. In addition, based on the Raspberry Pi, you can create a retro video game console or a multifunctional watch, for example, such as the PiClock.

As conceived by the author of the project, the gadget is capable of displaying the current time, weather forecast in the region where the user is located, as well as a radar map. The developer has posted step-by-step instructions on how to build the device on GitHub, but essentially all you need to create a PiClock is a monitor, a Raspberry Pi, a keyboard and mouse, and an active Wi-Fi connection.
