DIY lg TV repair no image

In detail: do-it-yourself lg TV repair there is no image from a real master for the site my.housecope.com.

No matter how perfect the technology from the LG manufacturer, it is subject to wear and tear and mechanical damage. This article focuses on such a problem as the absence of a picture on the screen when the sound continues to be broadcast, and the channels are switched using the remote control. Here we will consider what may be the causes of such a malfunction and options for eliminating these causes.

Inverter malfunction;
Breakage of the matrix;
Failure of the power supply;
Burnt capacitors;
The ribbon cable from the screen to the board is damaged or came out of the socket;
Burnt out LEDs;

In fact, it is almost impossible to diagnose all these problems on your own; this requires special knowledge and, at least, a minimum set of equipment. Usually, in this case, the owner of the equipment immediately contacts the LG service center, but we will nevertheless consider each of the problems in detail.

The inverter provides and regulates the supply of light, in other words, its malfunction will be the basis for the absence of an image. To determine the operability of this vital part for the TV, the first thing to do is to inspect the microcircuit, if burned parts or broken contacts are noticeable on it, then the matter is in it. Also, in terms of diagnostics, a multimeter will be very useful, it will show all the non-working parts of the device.

Still, a beginner should not take on the repair of the inverter, you can only aggravate the situation, immediately take the TV to the workshop or call the master at home.

If the matrix of your lg TV is out of order, then it's time for you to think about buying new equipment, since replacing this component will be very expensive, and it is relevant only for expensive models of goods in this category. In most cases, matrices cannot be repaired, and ordering a new one is quite costly, this also applies to the work of a specialist who will replace it.

The power supply responsible for the image may malfunction or even break down, its parts will need to be replaced. You can do this yourself, if you have a low-power soldering iron. If the contacts of the parts of the block turn black or the parts themselves are swollen, they must be replaced. You can also check the integrity by ringing the contacts. The most important thing in the process of repair work is not to damage the neighboring contacts and the microcircuit itself, otherwise the unit will have to be changed altogether.

Most often, capacitors swell, this can also be the reason that there is sound on the lg TV, but there is no picture. Naturally, it will not work to reanimate the capacitor, its replacement is also a simple process, like the actual diagnostics. It is not difficult to determine which of the capacitors burned out, it can be seen with the naked eye.

For a number of reasons, the loop that connects the device matrix to the microcircuit may fail, or it simply came out of the socket. If, upon inspecting, the loop is in its place, contact the service center technician.

Burnt-out LEDs can be added to the list of very common TV breakdowns, as a result of which the image will also stop broadcasting. Replacing LEDs is a painstaking business and requires perseverance, plus everything, one wrong move and you can damage the contacts, then you will have to pay for overhaul.

Do-it-yourself TV repair is a responsible business, since today a large number of different models (LCD, LSD, CRT) are presented on the market, each of which has its own technological features. Therefore, the approach to each type of TV is individual; in some cases, special skills will be required (knowledge of electronics, experience with a soldering station).

Before proceeding with the repair of television equipment, it is necessary to find out the cause of the problem.

The most common problems are:

TV screen does not turn on - this can happen with an old picture tube screen and with the most modern television panel. Basically, this symptom is characteristic of a blown fuse. When repairing, it should be borne in mind that the appropriate fuse must be selected for each model. And also experts recommend paying attention to the diode bridge, power supply, wire, perhaps the cause of the malfunction lies in these elements. Read also what to do if Samsung TV does not turn on.

Faint, barely noticeable picture - such a breakdown happens with LCD / LCD monitors. The most likely cause of the malfunction: faulty diodes, device backlighting.
There is no sound, the screen "wheezes" - most likely, the sound amplifier or microcircuit is out of order. Also read what to do if there is sound, but there is no picture.
Monitor is on, no picture - Perhaps the cause of the problem is in the video processor or in the receiving unit.

You should be aware that if a darkening of the board or rupture of elements is detected during a visual inspection of television equipment, then it is not recommended to immediately start replacing parts. Since such factors indicate a short circuit that could have occurred in another section of the TV. Therefore, if you do not eliminate the cause of the short circuit, but simply change the failed elements, then the situation will repeat itself.

To repair television equipment, the following tools and equipment may be required:

Screwdriver Set;
hex keys (in rare cases);
pliers;
soldering station (for repairing modern monitors);
screen layout (can be downloaded on the Internet);
multimeter;
oscilloscope.

Many LCD screen problems can be dealt with on your own. But you should know that these screens require more careful handling than, for example, CRT TVs.

First of all, the user needs to study the instructions for his model, and only after that start repairing the LCD or LED screen. You should be aware that LCD TVs use fluorescent bulbs for backlighting, while LEDs use LEDs.

The TV may not function due to lack of power, to check this, you need to do the following:

Open the back cover of the LCD TV with tools.
Disconnect the wires that are connected to the device matrix.
Connect a working light bulb to the contacts.
Some panels have more than one light source, in which case they must be tested as well. This can be done as follows: pull out the TV matrix and connect it to the network, it will immediately become clear which lamp is out of order.

After the faulty luminaire is found, it must be replaced. This procedure should be carried out as carefully as possible. In most cases, the lamp can be taken out even without removing the matrix - you need to move the protection elements and get the burned out part using a soldering station. Then a new lamp is installed in the same way.An important rule is that the new lamp must be completely identical to the old one.

Another common problem with these models is damage to the monitor. But in this case, it is not advisable to repair LCD TVs, since it is easier to buy a new screen. This test scheme can also be used to repair plasma televisions of all types. Read also how to fix the LED backlight yourself.

Each manufacturer has its own weak points, so below is a selection of the most common LCD screen breakdowns.

Often, users of this brand are faced with such a problem that when turned on, the device beeps without interruption. This symptom usually indicates that a leak has occurred. It is recommended to try replacing the preout stage diode.

Another common problem is that the monitor turns on and off itself. The main reason for this breakdown is a failed transistor, it is necessary to replace it. It is recommended that such malfunctions be eliminated on their own only by people who have experience in repairing television equipment.

DIY Philips TV repair is recommended if the problem is minor: settings are lost, cable replacement is required.

If the breakdown is complex, then it is better to entrust its elimination to specialists who will not only professionally perform repairs, but also issue a guarantee. Therefore, if the repaired screen stops working again, the user may demand a refund.

LG flat screen owners may have a problem saving settings. Such a problem does not require contacting the masters, you can repair the LG TV yourself. It is enough to switch the device to another operating mode, and all settings will be saved.

As well as in the case of other LCD models, if the problem is serious, then it is not recommended to repair an LG TV with your own hands, it is better to contact a specialist.

Despite the fact that today the majority of consumers prefer the most modern plasmas, CRT screens are still in demand. These TVs have their advantages: they are inexpensive, easy to operate, and the quality of the transmitted picture is still high.

The main problems with CRT devices:

the CRT TV does not turn on - just like on devices of a different type, first of all, you need to check the integrity of the fuses;
a diode bridge malfunction is a common problem with CRT receivers, you can fix the TV only after making a "ringing", you will need a multimeter from the equipment;
breakage of the posistor is considered the most serious problem; in order to check, it is necessary to turn off the power circuit of the TV, then start it again. After, observe the lamp, if it goes out, it means that the posistor is out of order. First of all, you need to adjust the resistance of the network, and then replace the part;
burnout of a transistor or capacitor - such a malfunction can be easily replaced by visual inspection (on black carbon parts), repair is carried out by replacing the part.

Below is a list of problems encountered by owners of CRT TVs.

The Rubin TV buzzes loudly when connected - most likely, the photodetector needs to be replaced.
The ruby does not turn on, the indicator does not light up - voltage surges in the transistor.

The Horizon TV does not have a blue tint, as well as the white balance is disturbed - this is mainly due to a break in the resistor.
There is sound, no image - the cause of the problem lies in poor contact of the power connector of the screen board. It is recommended to use a soldering iron to solder the harness into the Horizon TV board.

The screen does not turn on - there is a problem with the power supply.
A horizontal strip appears on the monitor - repairing a Vityaz TV consists in fixing a problem in the frame scan microcircuit.

Since the malfunction of the power supply is one of the most common problems of all types of TVs, it is necessary to study it in more detail.

Since all models of LCD monitors do not have fundamentally different design differences, therefore, the diagram below can be applied to all TVs (Toshiba, Horizon, Samsung, Sony, Rubin).

Repair of monitors equipped with a picture tube, for example, such as (ruby, sharp 2002sc, sony trinitron, vvk), as well as repair of Samsung TV, Panasonic. always starts checking the power supply.

Testing is carried out using an incandescent lamp, but before performing the procedure, it is necessary to disconnect Sharp c2002sc, Samsung or another screen from the load (horizontal cascade). The horizontal scan voltage can vary from 110 to 150 V, it depends on the size of the picture tube. It is required to find a sweep filter capacitor in the TV circuit. Next, you will need to connect a light bulb, in order to remove the load, it is necessary to unsolder the choke and the fuse through which the JV element consumes power. This scheme is used for sharp screens since 2002sc.

After that, connect the power adapter to electricity and measure the voltage, if the values exceed the norm, you will have to check the feedback circuit of the power supply. If the power supply unit is in good condition, then the light bulb is removed and all the elements are soldered into place. This is the basic information on how to repair a TV with your own hands.

In our time, a rare person does without a TV. Every year the models become thinner, larger and offer more and more new functionalities. Modern plasma screens with Smart TV technology have little in common with devices that were on sale some ten years ago. However, the commonality between the old and new generations still remains - breakdowns and malfunctions still happen. The reasons for this can be very different: blows, falling, ingress of moisture and direct sunlight, or an elementary marriage. In this article, we will take a closer look at what to do if the TV has lost the image, but there is sound. Let's figure it out. Go!

What to do if there is no picture on the TV

First, it should be noted that such a malfunction occurs quite often in a variety of brands of TVs. TVs of all brands are equally affected by this: Samsung, LG, Philips, Sony, Panasonic and many others. Therefore, it makes no sense to blame the manufacturer.

There are many reasons for the absence of an image on the screen, and you are unlikely to be able to determine it yourself by eye. Most likely, you still have to contact a service center or other repair service. It all depends on the nature of the problem. More on this below.

It happens that when you turn on the TV, a splash screen with the manufacturer's logo appears first (LG, Samsung, Philips, and so on), after which the screen simply goes blank. With this, you can change channels and hear the sound. Some users noticed that after a while the image appears, but when you turn it on again, everything repeats and the picture is absent. In this case, try the following tips:

Check the connection of the receiver cord as it may have become disconnected. Make sure the cord is plugged in securely.
Also, the problem may be in the cable itself. The wire may be damaged or simply be of poor quality. This concerns HDMI cables. In some cases, replacing the wire can correct the situation.
Check the power cable. It must also be securely connected.
Some users have found a rather original way to solve the problem - to increase the volume to the maximum (or close to it). After a few seconds, the image will appear and then you can set an acceptable volume level.

Please note that all the above tips will only help if the screen is working.This is indicated by the splash screen when the TV is switched on. If there is no splash screen and the screen is constantly dark, this already indicates that some component of the TV that is responsible for the image is out of order.

There are several components, failure of which can cause no picture on the screen. It is quite common that the inverter breaks down, which supplies voltage to the backlight lamps. The lamps themselves can also fail, and this, in turn, provokes a breakdown of the power supply. In addition to the above malfunctions, it is not uncommon for a matrix or motherboard to break down. Also, the problem may lie in the loops, converter and decoder. In this case, non-working parts and elements will have to be replaced with new ones.It is not recommended to carry out repairs on your own, since modern TVs are rather complex devices, and you risk aggravating the situation even more. The most correct decision would be to turn to professionals. This can be a service center of a manufacturing company or a private office, where repairs will be carried out efficiently and quickly.

One way or another, it is impossible to determine what is the reason for the breakdown of your TV without a thorough examination. In any case, the device must be disassembled and diagnosed for non-working parts and components. It is best if this is done in a workshop with appropriate conditions, however, if this option is not to your liking, many telemasters provide all of these services at home.

Of course, replacing some parts can cost a pretty penny, but it should be noted that matrices or motherboards themselves rarely fail. Usually damage occurs as a result of physical damage to the part, for example, when the TV falls or gets wet. In general, you cannot do without a telemaster.

Now you know what to do if the TV has lost the picture, but there is sound. You will also understand what could be the reason for such a malfunction.

Repair of plasma TVs: do-it-yourself LCD and LED, LG and Philips do not turn on, video and circuits, liquid crystalPlasma TV repair: 3 ways of carrying out Image - DIY lg TV repair no image

The experience of the craftsmen allows you to eliminate breakdowns of various nature and varying degrees of complexity Without video and audio equipment, a modern person can no longer imagine his life. As a result of regular and intensive use of equipment, it is subject to various breakdowns. The potential of imported and domestic TVs is very often violated. A posistor is responsible for this function. Another plasma breakdown can be discoloration, interference, the appearance of light or dark streaks during operation. But sometimes the problem might be with the outlet or power cord. This is only the most minimal description of the malfunctions, as there can be many more problems associated with the TV. Screen faults are the hardest to fix. If dark or light spots appear on the monitor after a shock or water ingress, then it is better to immediately take it to a service center, since only a technician can repair the device.

Before starting the repair work, it is imperative to determine what exactly has broken down and for this, the device is diagnosed. If the TV does not turn on, then a malfunction may occur due to a blown fuse. This applies to LCD TVs and CRTs. At the same time, as practice shows, the problem may lie in the failure of the diode bridge.

If the breakdown in the TV is insignificant, the repair is done by hand

TV repair is possible:

Produce at a service center;
Call the master at home;
Do all the repair work yourself.

Plasma TVs, in contrast to tube TVs, have many advantages, since they: have a richer image, are distinguished by a thin body, are characterized by high contrast and wide viewing angles. However, despite all the advantages, like models with a picture tube, they are susceptible to a variety of breakdowns.

All types of malfunctions that occur can be divided into several categories, namely:

Plasma panel malfunction;
Breakdown of the electrical circuit, receiver;
Problems with sockets, connectors, wires;
Dust build-up inside the device.

If the screen is broken, the image may be partially or completely missing. In this case, it will be necessary to replace the plasma panel in a specialized service center, and you will not be able to repair the TV yourself. If the TV panel is broken, you also need to replace it. If the problem is in the electronics, then the image may be distorted and disappear completely. Electronics can be repaired by yourself by re-soldering defective parts or replacing them with new ones.

However, it is imperative to have certain knowledge and skills in working with electronics.

If you carelessly handle wires, cables or connectors, certain problems can arise. Defective parts of the LED TV can be repaired, and in case of a serious breakdown, they can be replaced with new ones. The accumulation of dust inside the case can provoke the occurrence of various malfunctions, which is why it is better to clean the device in a timely manner than to repair the TV for a long time.

Repairing LED TVs at home can be quite a difficult and time-consuming task, which is why you need to pay enough attention to prevention, as this will help reduce the risk of breakdown.

Repairing LCD TVs at home is a solvable task, especially if you have basic experience in electronics

Preventive measures include:

The device must be in a ventilated area;
Dust cleaning should be done periodically;
Do not leave static pictures for more than 20 minutes.

Learning to repair a TV yourself is quite simple, the most important thing is to take into account the advice of professional masters. You can learn all the secrets of fixing LCD TVs by watching video tutorials for beginners, where everything is detailed for each brand of device.

Important! Before starting to repair the TV yourself, it is advisable to consult with a specialist, since the cause of the breakdown can be very serious and you can only cause even more damage to the equipment.

LG is considered one of the most popular home appliance manufacturers. The manufacturer is constantly improving the production of household appliances, introducing the latest technologies, which makes it possible to achieve the exceptional quality of appliances.

To determine how to repair LG TVs and other models, you first need to establish the cause of the breakdown

Basically, factors such as:

Ingress of foreign objects inside the vehicle;
Clogging;
Poor maintenance and misuse.

Before starting to repair an LSD TV, you need to prepare the appropriate tools and check the device for faults. Then you need to remove the back cover of the device and find the instructions, which will be written in Russian, so that you can study the configuration. Initially, the television receiver is inspected, and the reliability of the connection of all cables is checked. After checking the connections, you need to carefully inspect the cable equipment, because it can be the main cause of the breakdown.

If the cause of the malfunction lies in the power cord, then initially you need to replace it and only then proceed with further diagnostics of the device.

Often LSIDI TVs do not work due to a breakdown of the power supply. For the same reason, the computer can often fail. Breakdowns mainly occur as a result of excessive accumulation of dust inside the device. During the repair of an old CRT TV, you need to inspect the basement element of the picture tube. All threads must be illuminated. If you have to repair electronic devices for the first time, then the circuitry is initially drawn up.

Fixing a TV with your own hands is a completely doable task, the most important thing is to get acquainted with the peculiarities of the internal structure of technology from the beginning.

If the LED TV breaks down, two options can be assumed - either the power supply is out of order, or the backlight itself is out of order

The simplest are considered TV models such as:

In addition, among modern TVs, the Sony, Panasonic, Elenberg, Mystery brands differ in a rather simple device. Standard malfunctions are considered to be the lack of backlighting or intermittent loss of sound. In this case, it is important to determine the performance of each individual element. On TVs Supra, Samsung, VVK and others, the LEDs located on the tape often burn out. The issue is fixed by replacing them. The reason for the burnout of LEDs is mainly the constant overheating of the device and its operation at a critical temperature regime. In addition to replacing the LED, it is also important to align the heatsink as this allows for better heat dissipation.

The high reliability of the Philips brand TV guarantees its long service life, however, in some cases, various types of breakdowns may occur. Philips brand technology is of high quality and difficulty in eliminating breakdowns, since the device is characterized by the peculiarity of parts, in particular, such as a transformer.

If the indicator on the Philips TV flashes, it means that the TV itself diagnoses the type of problem

The most common types of malfunction are such as:

Lack of sound;
Blinking, intermittent disappearance or complete absence of a picture;
Image distortion;
Lack of response to commands.

In the case of a broken matrix, it is best to purchase another TV, as it will be very expensive to replace it. If you do not have sufficient experience in carrying out repair work, then you can watch video tutorials or entrust the elimination of malfunctions to specialists.

LCD TVs are a very reliable and functional device, however, if used improperly, if dust and foreign objects get in, as well as in the case of defects and many other problems, various kinds of breakdowns may occur. You can easily eliminate many types of plasma faults on your own, the most important thing is to first study the device of this type of technology.One of the most popular problems faced by the owners of smart TVs from the Korean company LG, when the image on the TV has completely disappeared, but there is sound. The symptoms associated with the transfer of content can be different:

The device speaks but does not show.

Unable to change channels due to black screen.

The backlight does not work.

The technique distorts the picture, turns it over and it becomes necessary to change the display format.

The TV shows dim and dim.

The broadcast on the display periodically disappears and the screen does not light up.

In this article, we will analyze what the causes of malfunctions can be, their elimination, and also what to do in each specific situation. Image - DIY lg TV repair no image

The most popular reasons why the ice TV does not show digital and analogue channels are considered to be faults in the hardware components.Problems with the power supply, or the color unit, a burnt-out inverter, breakdown of matrices and capacitors - all this can lead to the following:

Shows no gear.
Shows them in green or black and white.
Broadcasts an inverted image.
Other variations, when there is no video sequence, but the sound works (more on them later).

To solve problems when the screen does not show - the logo does not appear and subsequent broadcasts - a visit to a private master in a repair center or self-diagnosis and repair of a breakdown on your own will help.

If the sound comes at normal audio noise volume, but the screen remains dark, one of the diagnostic measures will be to test the cables transmitting the picture:

Antenna.
HDMI.
From your cable provider.
We check the availability of the Internet (in the case of digital set-top boxes from providers).

To do this, you need a special utility called Moninfo. It is designed to find some problems with the transmission of sound and video signals. If the application detects malfunctions, you should carefully examine the cable pins for damage.

Perhaps the most common reason why the image on an LG TV disappears is a matrix breakdown. Because of this, it starts:

jump video,
an afterimage is shown on half of the monitor,
there are stripes across the entire display (white, yellow, pink, or multi-colored).

As a rule, this TV part breaks down under the influence of external signs: moisture, strong shocks or falls. In such cases, the display cannot be repaired, and you will have to replace the matrix (or, as an option, buy new equipment). But if the malfunctions arose without any visible prerequisites, for example, the picture began to bifurcate or "cloudy" abruptly, then they can be corrected in the technical service, without replacing the module with a new one.

Self-replacement of the matrix at home is also allowed, however, it will be very difficult for a layman to do this. The first difficulties will begin already during the preparation for the repair: it is rather difficult to get a suitable matrix, and it must be ordered from certified service centers. Otherwise, there is a risk of running into a fake and the work will be "down the drain."

Problems with capacitors in LCD TVs occur due to strong voltage surges in the network. External signs of a malfunction are manifested in this way: the display goes out and the transmission disappears immediately after switching on or after a short period of time, the broadcast becomes double, or the brightness disappears - the colors become darker. After disassembling the device on the board, you can observe a swollen or exploded capacitor, and the eternal companion of such a situation is a blown fuse.

Please note that after an overvoltage, it is the power supply unit of the equipment that breaks down very first. The complex of diagnostic procedures completely repeats the instructions from the previous section. As in the case, the electronics repair must be entrusted to an experienced craftsman so as not to harm the device and not completely break it.

The main signs by which it can be determined that the cause of the plasma malfunction was precisely the broken plume of the matrix, the following situations are considered:

The image periodically disappears on the TV.
The equipment stopped showing a normal picture - ripples and interference appeared.
Display distortions appeared: the screen began to strip or duplicate in any geometric order.

After contacting the service centers, there are two options for the development of events:

Repair of the loop.
Replacing a defective part of a part.

The first option disappears due to its inexpediency and complexity, since it is much easier to dismantle the breakdown and replace it with a working part than to try to repair the LG equipment. It is categorically not recommended to carry out any manipulations on your own.

One of the most popular reasons for this problem is the situation when the screen backlight does not work. In LV technology, failure of LEDs in LED backlighting is far from uncommon. It is determined quite simply - if the picture "blinks" and ripples, then the root of all evil lies in the faulty illumination of the polymer liquid crystal layer.

It is almost impossible to repair such a malfunction at home, if only due to the lack of the necessary parts - ordering them from an official distributor is expensive and time-consuming, and unfortunately, such components are not supplied to the radio market. Therefore, the best option to fix the equipment would be to send it to a certified service center.

It is impossible to describe all possible malfunctions with a voltage inverter in an LCD device.

The image is flickering and distorted.
Video appears for a long time or does not appear at all.
After starting, the display of the device dims and goes out almost instantly.
There is sound, but the screen is dazzling.
The broadcast looks vague or so dark that it is impossible to make out what is happening.

This module is responsible for supplying energy to the backlight lamps, in addition to this:

Converts 12 volts DC voltage to high voltage AC;
Stabilizes the input current of the lamp to the required values;
Adjusts the brightness of the backlight;
Matches the output stage of the inverter with the input impedance of the lamps;
Protects electronic boards from short circuits and possible overload.

After a careful external examination and diagnostics of a broken inverter, someone who knows how to handle a soldering iron, a multimeter and has basic knowledge in physics and electronics will be able to repair it. It is difficult to say exactly where these parts most often burn out, since the problem can manifest itself anywhere: in lamps, transformers, "keys" or controllers on the board.

If there is sound on the LJI TV, but there is no image, while the picture is constantly twitching, it has become dim, displayed incorrectly or appears on the display with a delay, the problem is in the faulty power supply.

It is categorically not recommended to carry out manipulations without experience in repair and knowledge of electronics. It is better to pay money and call a TV technician who will quickly diagnose the breakdown and fix it.

But the initial inspection to detect problems can be done independently:

Discharge the capacitors - remove the plug from the socket (for the desperate - short-circuit it with any conductor). Open the back cover, check the cables for kinks and breaks, the buttons and the fuse are working.
Inspect the power supply for swollen or melted capacitors or resistors. If any, they should be replaced.
Measure the voltage of the output circuits of the power supply. The values must match the numbers indicated in the documentation or on the board.
If the voltage differs and reaches a value of approximately 200V, it is necessary to look for the cause of the malfunction in the primary circuit.
If, when tapped, the TV reacts, video blinks or colors change, the source of the problem is poor soldering of modules or wires, and it is it that needs to be repaired.

This article has described all the possible situations and reasons when there is no image on the LG LCD TV. If the plasma technology works with sound without a picture, channels are not displayed on the TV, the screen is dark, only the logo is lit, or it is impossible to watch movies, then the problem is most likely a hardware problem. To diagnose and purchase components for repair, you should contact the company representatives who assemble LG devices or repair points.
