LEDs for led samsung TVs. LEDs for LED highlighting TV

If, after turning on the liquid crystal television panel, the user hears the sound, but the image on the screen is missing, this may indicate the failure of the LED backlight. To diagnose and eliminate malfunction, you can call a representative of the service center, but, knowing the procedure, having spare parts and required tool, You can repair LED TV backlight and do it yourself. The rules and algorithm of the actions of this process are further in the material.

Causes and signs of faulty backlight

The TV screen consists of a plurality of points - pixels located close to each other, and so that the user see the image, the light should be served on them, then they "come to life" and form a picture. LED technology in LCD TVs is new way Screen backlight using LEDs that came to replace luminescent CCFL lamps. Devices with LED illumination are distinguished by excellent color reproduction, high contrast, incredible clarity and realistic image, low electricity consumption and small thickness.

Types of backlight

Depending on how LEDs are located, two types of LED backlight are distinguished:

  • edge (end, side) Illumination involves the location of the LEDs along the left and right edge, from above and below or around the perimeter;
  • direct (matrix) Illumination indicates the distribution of LEDs throughout the matrix area.

With the first type of LED location, it is impossible to achieve uniform highlighting the screens. In the second case, the diodes are located along the entire matrix, due to this, the uniform illumination of the entire display is ensured, as well as the highest contrast and rich black light.

Causes of breakdown

If the user includes a television and detects a lack of pictures or video, but the sound is played, this may indicate the backlight breakage.

Important! To make sure the backlight fails, it is enough to send a burning lamp on the screen. If a picture appears - this confirms the assumption.

There are several reasons why LED backlight fails. First, maybe damaged tape diodes. The LEDs are connected in series, which means if at least one stops to work, the whole strip will go out. In this case, the voltage will continue to be supplied. Secondly, maybe broomLed.-driver. In this case, the lamp does not receive an image, so they do not light up.

Sometimes the TV still comes from the factory with marriage. After all, just just one faulty LED so that the screen of the television receptionist does not work. In other situations, the lamps will be fascinated by the fault of the user who sets the maximum screen brightness - the voltage increases, the LEDs do not cope with it and burn out. The store can also be to blame the store in which the sellers are trying to attract the attention of buyers with a bright image on the screen of the television panel.

Detection of malfunction

To eliminate a malfunction, it is necessary to understand whether the LED tape is really its cause. To this end, you need to disassemble the TV book and inspect its components.

Tip! If the user is not sure that he will be able to correctly fulfill all the necessary actions, he should refer to the specialists in order not to risk the device and prevent the deterioration of the situation.

For diagnostics you need to perform partial disassemblytelevision panel and a number of measurements. So, the TV is required to put down the screen on a solid surface, for example, a table covering the bedspread or sheet to prevent damage to the matrix. Next should be removed the leg, and then unscrew the entire fastener holding the back cover, and remove the last to the side. If it is not removed, you need to find a bolt that is not duck with, and remove it.

Now measurements. First you need to check the voltage on the driver. If the output value is 220 volts at the output, this means that the part is working and feeds to the tape. Next, you need to diagnose the backlight in the same way. If it is faulty, the value will be 100 volts. For repair, the user will need to remove the matrix.

On a note! Usually in the LCD TVs use special LED strips with lenses, providing a smooth and clear lighting of the matrix.

What you need to eliminate breakage

To troubleshoot the user, the user will need a tool, as well as new LEDs. Buy lED ribbon. in service center It will not work - there they do not order them and do not sell. It is possible to order such a product from the manufacturer's company, but the delivery will take a lot of time, and the price will be too high. Best exitchange separately faulty LEDs.

Tip! Working lamps can be found in the markets, in repair shops, services, etc. The main thing is that they have been working, therefore, you can also acquire the repaired (from non-working television receivers).

On different models of the same company can be various number LEDs. For example, if there is a 32-inch 32LN540V-ZA diagonal on TV 32LN540V-ZA (3 rows of 7 lamps), then on 32LB522U, this figure may be different. In addition, the greater the diagonal, the greater the number of LEDs is used to illuminate the matrix. For example, 112 light bulbs are installed on the Samsung UE40ES5507K TV. Therefore, it is possible to determine the number of items in your TV book only disassemble his.

Disassembly of the teleceptor

Actions to replace LEDs are performed equally on all television panels, whether LG, Samsung, Philips, Toshiba or the technique of another brand. Before starting work, it is necessary to prepare: next to the table on which the TV is lying, put the second to put the parts (matrix, LED tape, panel). Then need wash hands thoroughlyIn order not to leave the dirt on the matrix or filters, which, after assembling a television, can weepingly affect the picture quality.

Tip! When disassembling a television panel, it is necessary to very carefully handle the decoders - any careless action can tear the train.

In any TV, regardless of the receiver, is three keyboards:main., T.- con. and power adapter. They are easily detected immediately after removing the back panel.

To disassemble a telephoneial, you need:

  • remove and pull the T-CON fee, pre-filled fasteners and disconnecting the loops;

  • remove with metal protection from decoders, disconnecting the side fasteners and remove the bolts, after which they will hold them only fastenings of rubber;

  • unscrew the bolts holding the front frame, turn over the TV guide on the back side and remove the frame;

  • carefully turn the TV, holding the matrix;
  • disconnect the rubber locks that hold the decoders;

  • remove the matrix and remove to the side.

Debugg

To access the LED tape, you need to remove the plastic frame, previously removing the fasteners. You also need to remove the films scattering light. In the TV vertices with LED illumination, the LEDs are connected consistently, and therefore, if one of them is damaged, the rest will not burn. To eliminate the breakdown, you need to replace the LED to the new one. If there are no signs of burning, it will be necessary check each separately.

Testing planks

In order not to test all the LEDs, you can feed the voltage separately to each bar. If the lamps are used on it, it will shine. Otherwise, you need to ring each LED on the bar. Usually there are contacts to connect a multimeter. Connect probe follows compliance with polarity. With the right connection, the whole LED glows. If the multimeter is connected correctly, and the lamp does not burn or demonstrates short circuit, It says she is faulty.

Replacement

To eliminate the spoiled element, you need to remove the reflective lens from it. The bar is fixed with bilateral scotch, so it is necessary to warm it with a hairdryer to dismantle. Next, it is necessary to securely fix the part and warm the solder hairdryer from the bottom near the LED until the tin is melted, and the lamp will not be disconnected. A new LED is sold in the same way or a very thin soldering iron.

Important! It is necessary to act very carefully, so as not to melt the diode during heating. If the LED is not suitable in size, then a minus pad (usually it is more plus) it is necessary to cut carefully, and then pour the lamp.


If lenses are removed during the work, it must be borne in mind that they are fixed by a compound polymer resin that performs the role of protection and insulator. You should be disconnected very carefully, but to install for your previous place - using superclone And in the same position not to disturb the focus.

Exists another replacement methodwhich is relevant when you melt the spoiled LED is almost impossible. It is necessary using the metal hacksaw to cut a faulty lamp along with the parts of the bar on both sides. The same actions must be performed with a new part. After that, it is necessary to remove the paint from the tracks on a piece with the LED and on the bar and gently solder them.

Completion of repair

After completing the work on the replacement of LEDs, you need to fully assemble the television panel connect the voltage to the straps and checkwhether the tape is burning. If all the lamps are functioning properly, you need to restore the television receptionist in the reverse order, performing all the actions as carefully.

Tip! If the user has made photos in the process of panel panel panel process, it is recommended when assembling before each action with them to be checked.

After the technique is collected, you need to install it on the source, connect to the network and enable. If the image is good, there are no light on the matrix, as well as any stains, it speaks of correctly performed work and successfully completing the repair operation of the LED backlight.

Prevention

To prevent the failure to repetition, you need to open the menu of the telephone player, find the backlight brightness in it (you do not need to be confused with the brightness of the screen) and set this indicator by 75%. In this case, the lamps will function in normal mode, and they will be applied to them (and not increased) voltage, which will significantly extend their service life.

So, if the TV does not output the image, but the sound is present, very often the reason lies in the faulty LED backlight. For its repair, you can resort to the help of a specialist, but, knowing the right procedure for actions and bought new details, you can repair the TV on your own at home. However, if there is no confidence in your abilities and experience in thin radio electronic works, it is better to use the services of a professional master in order not to aggravate the situation.

In the work of even the highest quality equipment, various failures and malfunctions appear. Therefore, each user should be ready to be to the fact that they will have to repair the equipment with their own hands, because the service centers will be paid for payment services.

Today it will be about the most popular breakdown - a malfunction of the highlighting ice in LG TVs. It is with such a problem that ordinary users most often appeal to service centers. Few people know that it is possible to normalize the operation of the device and on their own. Special skills will not need, the main thing follows the instructions.

Before starting repairing the LG TV illumination, you should first figure out how this component is arranged, what is its functions and what is it necessary for?

What is LED backlight?

Abbreviation LED decrypts Light Emitting DIODE, which is translated from English as a diode emitting light. If we say in the context of the television equipment industry in the context, this reduction denotes the type of liquid crystal matrix and illumination with light-emitting diodes.

After the new type of highlighting of the LCD monitors was presented, the manufacturers began to replace the LCD abbreviation in the name of the LED abbreviation models. Of course, LG TVs did not exception from this rule.

In fact, the motive for such changes was the marketing tasks rather than the real necessity. The fact is that the LED backlight of the matrices is not fundamentally new technology Production of television equipment screens. This is just an updated lighting method. However, the trend harmoniously worried, so the term Light Emitting Diode is actively used today.

The most ordinary TV matrices are based on the use of a cold cathode lamp, essentially all the same fluorescent lamps. As for LCD and LED models, they are characterized by emitting light diodes.

It's no secret that LCD screens Consist of pixels with liquid crystals. The position of the crystal in pixel determines whether the cell is missing. Actually, the screen will be made.

The quality of the screen matrix defines a huge number of parameters, in particular: the level of dark shades, the viewing angle, static contrast, the image update frequency and even response time. Liquid crystal matrices are produced by several technologies. We list the most popular: TN, IPS, Pls.

As for the backlight directly, it affects the brightness, color transmission, coverage, dynamic contrast. However, it is still necessary to estimate the parameters in the complex, given the type of the matrix and the backlight.

Thus, buying a TV with LED backlight, the user receives:

  • balanced contrast;
  • saturated brightness;
  • high clarity pictures;
  • color palette.

In addition, LEDs consume much less electricity, by about 40%, rather than analogues. Direct daylight lamps, which are also used in the production of television equipment, contain mercury, which negatively affects ecology. In this regard, the advantages of the ice are obvious.

It makes no sense to argue, modern TV devices with backlit, consisting of LEDs, provide a broadcast of the most bright image. Dynamic contrast appears - regulation of the brightness of the glow of diodes for different parts of the monitor. The image becomes more realistic.

Adjusting the glow of diodes directly in the process of viewing TV, has a positive effect on the level of black. When dark shades appear, the backlight level is reduced, as a result, the screen darkens.

Causes of lighting illumination

High-quality television equipment can work out long enough long, respectively, illumination problems appear after an impressive period of time. Unfortunately, this cannot be said about Chinese manufacturers.

Why not backlight? There are several reasons for the appearance of a malfunction, analyze each of them:

  1. Digured a certain line of diodes. LEDs are characterized by a sequential connection type, this means that if one element stops working, then the entire component fails. However, the voltage (about 200 volts) continues to enter the light bulb.
  1. Problems with the LED driver. The image disappears on the LG TV due to the fact that the voltage vice versa is not fed to the LEDs, respectively, they do not light up.
  1. Manufacturing defects. Sometimes only one LED does not work, but the TV device screen does not light up.
  1. The user exhibits the maximum image brightness, which leads to an increase in voltage, as a result of the diodes do not stand and burn out.
  1. Sometimes incorrect settings The voltage-supplied on LEDs is the wine wines in which you purchase TV. They are trying to attract buyers with a bright picture.

Now you know why the LED lights of the TV comes out. This breakdown occurs quite often, but if you follow the manufacturer's recommendations, you can significantly extend the operational period of the device.

Professional repairmen with the help of special equipment will determine which module failed. As the usual user understand that the LG TV screen does not work? Now we will analyze the az diagnostics.

Diagnosis of television

How to determine whether the backlight came out? It all depends on the symptoms. For example, LCD TV starts off the remote remote controlBut there is no image on the screen. Direct the flashlight on the screen, as a result you will see a dim picture. In fact, the flashlight performs the functions of the forced backlight.

Based on this, we conclude that I broke either LED Driver or backlight. To specify the source of the problem, you should disassemble the TV and thoroughly inspect the elements of the hardware component.

Remember that disassemble the body of the TV is only provided that you have previously had a similar experience. If there are no skills, it is advisable to contact the service center. Once times better not to risk. Since there is always a possibility to make worse, that is, aggravate the original breakdown.

To dismantle rear panel TV devices from the company LG, it is enough to simply unscrew the special bolts that provide fixation. Make it easy. First disconnect the delivery and dismantle the mounts. If the lid is still not removed, it means you need to find a blocking bolt.

When the rear panel is removed, you should check the backlight and output voltage. For example, if the highlight voltage is 100 volts, then the component failed.

In most cases, LG TVs are equipped with a LED set with lenses, it is located all over the perimeter of the screen, providing clear lighting. To get to this detail and repair it, it should be dismantled to the matrix.

Now you know what to do if the TV is turned on, but the image is missing.

Disassembly of the product

Regardless of the model, television equipment is equipped with three keyboards: Main, T-Con and the power adapter. Immediately after removing the lid, you will see them.

Disassembling LG LG - an extremely complex and time consuming process, observe maximum caution, since there is a risk of damage to other hardware elements. To carefully disassemble TV, follow the following recommendations:

  • prepare the work area in advance and two tables tightly standing together, which will fit the components: matrix, LED ribbon, bar;
  • before you start disassembly, wash your hands to not pollute the filters or the matrix. In the future, this will negatively affect the image quality;
  • special attention should be paid to decoders if you do not comply with accuracy, it will simply break the loop.

Step-by-step instructions on disassembling television equipment:

  1. Disconnect the plumes and unscrew the bolts located between them to disconnect and remove the T-CON fee.
  1. Remove the metal protective elements with decoders. To do this, unscrew the mounts located on the sides and bolts. As a result, the decoders will be held exclusively on rubber fasteners.
  1. It's time to remove the front frame of the device. Remove the screws around the perimeter and place the product on the rear panel. Remove the frame.
  1. Turn over the screen holding the matrix. Decifrators must be from above, you can disconnect the rubber fasteners holding them, the main thing is to do everything very carefully.
  1. We disconnect the matrix and put it on the pre-prepared table so that it does not interfere with the backlight repair.

In principle, a TV device will be able to disassemble every wishes, the main thing to be as accurate as possible.

Definition of non-working LEDs

Earlier, we reviewed the process of disassembling the TV, now proceed directly to repair. To replace the LEDs in the backlight, carefully drop all the mounts, and then dismantle the plastic frame. We remove the scattering films in order to open access to faulty items.

The structure of the Ice backlight directly depends on what model of television equipment is in question. For example, for LG 32LB582V three rows of LEDs for 6 pieces. Model 32LN541U has one diode in each row more.

Television equipment in which such lighting technology is used is characterized by a sequential connection of diodes, so if only one element burns, then absolutely the entire system fails.

In the event of a driver breakdown, the voltage will overreve the entire system. If only one diode begins, then the voltage will be, but there is no proper lighting. The chain is open. Therefore, you need to change the faulty LG TV LEDs for correct viewing.

Approximately the backlight system has about 18 diodes, the stress measurements showed that 140 V is supplied without load, this means that each element is separately 7.8 V.

Why are all these calculations need? The voltage level of each strip and total load allow you to calculate the power of the used LEDs. It is extremely difficult to find a faulty element of the system. If fasteners are not burned, you will have to tweak absolutely all diodes.

Replacing LEDs

It is extremely difficult to replace the LG TV backlight extremely difficult, it is possible that you have certain difficulties. Suppose that during the diagnostic process you managed to determine a couple of damaged diodes. Purchase a plank new light bulbs is very problematic. Service centers do not supply these parts, so the only output is the purchase of the manufacturer. It is clear that the deliveries will have to wait for a very long time, not to mention the cost.

In order not to buy a bar, you should replace LEDs in LED LG TVs one one. You can buy on the market. Mostly sold already soldered details, but nothing terrible, the main thing is that they worked.

Remember that absolutely all the planks are fixed with the help of bilateral scotch. Consequently, they need to warm themselves with a soldering hair dryer so that Scotch's fixation. Secure the LED bar in a special holder. Her hair dryer from the bottom, as a result of tin will be melted. So the broken part is removed. Soldering is carried out in a similar way, only this can be changed the item, while without damaging it.

Remember that in the factory conditions, absolutely all lenses are attached to the compound, therefore, in the process of their dismantling, be extremely careful. Each of them will have to install in its place. In order not to disturb the focus.

There is one more subtlety: it is possible that you will find LEDs with a minus platform big sizeTherefore, a plus will be less. Cut the contact place to solder a diode.

In the event that the paint will be a bit damaged - nothing terrible. According to the same principle, the remaining elements of the design are soldered. As for the lenses, they need to be glued with a super block.

Note.

  • Prices are 15% below the procurement due to the purchase of components directly from manufacturers
  • Express diagnostics of technology for 15 minutes - 0 rubles.
  • Urgent repair of the device from 30 minutes
  • Official guarantee up to 6 months

Repair LED backlighting Samsung TV in St. Petersburg

LED or LED screen backlight gives better compared to the lamp (LSD) system image, and installed in all modern TVs.

If you turn on the TV, you saw a dark screen with normal sound, it is possible to repair the Ice highlight of the Samsung TV. The black screen is characteristic of other types of faults, but you can make a small diagnosis yourself, leaving the lamp screen. If there is a dull image - repair LED highlighting the Samsung TV "is inevitable".

Replacing the LEDs on the Samsung TV is needed when they are braveled. Most often one or several LEDs burns out, but the system turns off anyway - so the inverter protects the TV from the closure. The brave of all elements is usually occurring after the voltage drop or the LED driver failure fails.

Repair Ice highlighting the Samsung TV must be performed in an authorized service center, as it requires a television parsing. An illiterate procedure performed may result in serious faults, eliminate which will be much more expensive. Our service engineers have tremendous experience and modern tools for repairing Samsung TV. We carry out the replacement of LEDs on the Samsung TV only on the components of the AAA class. All these factors guarantee high quality Repair.

Without such a backlight, no liquid crystal TV can work normally regardless of its brand. We will tell how to make a repair of LED highlighting the TV at home on the example of a device from LG, and what you will need for this.

How to determine what illuminated is broken? Suppose that the fault of the LCD TV is such: turns on from the remote control, but the screen does not shine (if your TV does not turn on even from the console - read О). When the display is directed light from flashlight (i.e., forced backlighting), the image manifests itself. The verdict - the ice driver or similar backlight does not work, may be due to the fact that the special rules with soldered LEDs are blown. You need to disassemble the TV and visually inspect the details in troubleshooting.

Attention! You can open the TV LCD housing only if you have skills to work with complex devices and a small experience, otherwise it is better not to risk.

Remove the back cover Any TV brand LG is simple, just to do everything neatly and without a rush: we disconnect the stands of the stand and unscrew the mount throughout the perimeter of the product. If the lid is not removed - it means there is a blocking bolt, you should not make an effort, you need to find it and unscrew it.

After removing the rear cover, check the output voltage.

If it is normal - check stress Ice backlight Screen itself. The value of its total is 100V, which indicates the presence of a lighting of the LCD TV.

In such TVs, a special LED set with lenses is used, which is installed throughout the screen area to provide clear illumination. To get to them, and repair the LG TV illumination, you must first remove the matrix.

Disassembly of the product

The TV has three main boards - main, t-con and power supply, all of them are clearly visible in the photo.

Removal and disassembly of the matrix With your own hands - the work is very painstaking, one careless movement, and you can buy a new telly, so it is better not to take to repair without experience. Experts identify such highlights when disassembling the matrix:

  • it is necessary to prepare place of work and two tables for which laying matrices and scattering films;
  • before starting this work, you should thoroughly wash your hands to accidentally not leave the traces of dirty fingers on the filters and the matrix itself - it can harm the image quality afterwards;
  • special attention should be paid to decoders - one inaccurate movement can entail a loop break.

Subsequent dismantling is carried out in several stages.

Finding a fault

Now it starts directly repairing the LED TV illumination: for this you need the contour to deduct neatly all latches, remove the frame from the plastic and remove the scattering films to open the LEDs.

W. different models LG TVs will have its own set of backlighting: for LG 32LN541U - these are three rows of 7 LEDs, and for LG 32LB582V - three to 6 pieces.

In all TVs where such a backlight is used, the LEDs are connected in series, so when one of them is bravely, the entire system stops working. If the LED driver is defective, then the voltage is not received by the entire system, and when one of the LEDs burned out, the voltage goes, but all the efforts of the device will light up the system in vain: even give 200 volts, the circuit is open.

As you can see from the photo, the backlight consists of 18 LEDs, when measurements, the voltage without load was 140 V, that is, it accounted for 7.8 V. When we take into account the voltage drop on each bar and the overall load, the output will be like this: in this model are used LEDs on 6 V.

Find a blown LED is not easy: if there is no burning at the place of attachment, then you need to check each element separately.

Replacing LEDs

Replacing the LG TV illumination can cause certain difficulties. Suppose, on the results of the inspection, several faulty LEDs were revealed. It is quite difficult to buy a shift bar - these parts are not supplied to the service centers, you can order them on the manufacturer's website, but it is long and very expensive. So, there is only one way - replace individual diodesAlthough it will not be easy to find them on Radiorenka. Experts assure that you can buy already soldering, but serviceable, after a long search, just that were purchased.

Users should know that all the planks are glued with bilateral Scotcha, Therefore, it is necessary to warm them up with a special soldering hair dryer so that Scotch has departed. For this, the bar is fixed in the holder and heated from the bottom with a hairdryer, tin melted, and the faulty item is removed. It follows exactly the same method so as not to damage the LED.

Important! All lenses at the factory are fixed by the compound, so when they are removed, it is necessary to act very carefully, while each you need to install each other in order to not disturb the initial focus.

Another nuance: LEDs can be cracked, which have a minus playground a bit more than a plus, so you need to trim the contact location to enter the diode. So the deployed LED looks like:

What is damaged a little paint is not trouble. In the same way, the rest of the LEDs are depicting, and lenses stick to superciles. And this is a renovated view of the collected and ready for the further operation of the backlight panel:

As you can see in practice, in the repair of LED backlighting the LG TV matrix there are many specific nuances, and not knowing them, it is impossible to achieve a positive result.

Final work

When the repair of the LED LG TV system was carried out completely, before performing the final assembly, connect the voltage to the straps and checking the glow of all LEDs. If everything is fine, then you collect the TV, performing all operations consistently and with caution, as well as when dismantling.

After completing the backlight brightness, it is better not to remove to a maximum, and limit to 75% - with this mode, the LEDs operate in normal mode and, according to experts, they will serve much longer.

We install the TV to the previous place, turn it on to the network and enjoy the quality: if there are no extraneous spots on the screen on the screen, it means that the repair was performed correctly, in compliance with all the recommendations. And get the maximum of the possibilities from your TV by learning how it is

Hello everyone. In this article I will talk about LED backlighting TV matrix, namely, for what reason the LEDs are burning in the backlight, where they can be bought, and how to prevent them from re-out.

About LED backlighting TV matrix.

The first LCD televisions had a backlight made using fluorescent (CCFL) lamps. This type The backlight worked very well, but the brightness of the glow left much to be desired. Such TVs were inferior as a plasma panel as an image, but won on their dimensions, and weight.

As science does not stand still, instead CCFL lamps LEDs that their bright glow and low current consumption have begun to be used in the development of LCD televisions. Of course, the matrices themselves, too, during this time, have improved much in quality and color, so that the dull glow of CCFL lamps could not fully pass the picture that manufacturers would like to see.

The reasons for the failure of the LED highlighting TVs.

Since I often repair TVs, and on my old site more than once described the repair process, then for myself I can select several basic causes of failure of LED LEDs.

The first reason - This defects the manufacturers themselves. Very often, based on my practice, the manufacturers themselves configure the backlight driver in such a way that there are current on the line of LEDs, more laid, as a result of which the LEDs are overheated, and fail.

The second reason - This is a marriage of the LEDs themselves. It happens that the disassembly matrix finds only one faulty diode. At the same time, the current that goes on the matrix is \u200b\u200bwithin the normal range, and all other LEDs are in excellent condition.

Third reason - Directly related to the first. Some owners love to watch TVs on the maximum brightness (the backlight is on 100%). Since manufacturers of some TVs specifically overestimate the current that enters the LEDs, viewing in this mode It does not pour the life of highlighting TVs. I recommend not to increase the backlight level of more than 70%. In this mode, your TV will work much longer.

What LEDs I use to repair LED backlighting TVs and where I buy them.

All LEDs I buy on AliExpress in proven sellers. How to search and replace LEDs on the planks, I will show in subsequent articles, and now I will lay out a list of the most popular LEDs that are used in the repairs of the backlight.
