How to determine the cost of repairing your HYUNDAI TV?
You just need to call us and an experienced master consultant in 80% of cases by phone can determine the cost of repairing your HYUNDAI TV.
The fact is that each TV model has its own typical malfunctions.
According to statistics, 8 out of 10 breakdowns are typical. To determine the cost of repairing your HYUNDAI TV, you need to call us, name the model and brand of the TV, and also briefly describe the manifestation of the malfunction.
For example, a Hyundai TV, model H-LCD2200. There is no picture, there is sound.
The make and model can be viewed on the back of the TV. Consulting a wizard by phone will help you decide what to do next - buy a new TV or make an application to repair an old TV.
Sometimes the cost of repairs is 50% or more of the cost of a new TV.
In this case, you should think about buying a new TV if the old one is not dear to you as a memory or you are used to it.
Either way, fixing an old TV is cheaper than buying a new one!
Repair of the HYUNDAI CRT TV makes sense if the TV CRT is in good condition. With LCD TVs HYUNDAI (Hyundai), the situation is about the same, if the LCD matrix is in good order, then the repair makes sense.
As for the HYUNDAI projection TVs, they have their own typical malfunctions. There are two types of projection TVs - CRT and LCD.
In CRT projection TVs, the information chips mainly fail. This breakdown is eliminated relatively inexpensively by replacing the information microcircuits.
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.

Probably, many are familiar with the situation when the TV stopped showing signs of life when the owner intended to turn it on. Now we are calm about this, since we understand that you can use another TV in the next room or in the kitchen, and the faulty device can be repaired over time. But, if you look back thirty, forty years ago, the refusal of the TV to turn on would be perceived as a big nuisance. TV then, despite the ideology of the programs, for many people was the only window into the world. It was in no way possible to skip the episode “Seventeen Moments of Spring”, and the feelings about this seemed quite reasonable.
There is no doubt that the technique has become more reliable and technologically advanced over time, its weight and dimensions have decreased, and many new user and multimedia functions have been added. However, nowadays, as well as at the dawn of its formation, television receivers are sometimes prone to failures when turned on. There may be many reasons for this, and the apparatus itself is not always the “culprit” of such strange behavior.
It is quite easy to verify the opposite. You need to check the electrical outlet where the cable from the TV is inserted. Plug in a table lamp and make sure it works. Remember where your device has the power button, and if there is one at all. This is no joke, many owners forget about its existence, using only the remote control.
The assortment of TV sets is so diverse and wide that even a master on TV in a model not very well known will take some time to find the mains switch. These elements of the scheme tend to hide in nooks and crannies, below, on the side, behind and be completely invisible. Accidentally hitting this button and not noticing it, then you can ask for a long time the question "Why does the TV not turn on?"
Of course, situations with a button or a bad outlet are not typical and are quite rare, but by checking these things it is worth starting to diagnose the reasons why the “box” does not want to turn on. Most often, the receiver itself is to blame and the owner has to make a decision whether to call a master or fix the TV with his own hands.
For many men who consider themselves technically literate, the issue of TV repair does not seem so difficult. “There you just need to replace the fuse, or something else, but to fix it you need a tester, a soldering iron and a circuit,” some confident people think so. However, the desire to repair the device on its own can decline after the cover is removed from the device and access to the boards and blocks of a modern TV is obtained.
The fuse, as we are used to seeing it, in the receiver, most often, is one and in most cases intact, if there were no farce-major circumstances in the form of a thunderstorm or large voltage surges in the electrical network. It may well be that the fuse on one of the boards has blown, but most of the "fuses" are now made in an SMD case and the search for a faulty one may take a long time, since there can be dozens of these components, and they are located in any television unit. It is rather difficult to visually determine their presence in the circuit and distinguish them from similar in appearance capacitors or resistors without proper skill.
Let's say the search was successful. Here it is - a burnt out "fuse" (fuse), which needs to be replaced and the hope that the TV will again delight us with juicy stories and heartfelt stereo sound will come true. However, joy can be premature.Questions should arise: "What is the rating of the defective fuse?" and "Why did it burn out?" If you don't think about these things and just solder a wire instead of a spare part, you can discover a lot of new things: see the smoke from a large microcircuit or hear the crackle of exploding transistors. This means that you have not found the cause of the blown fuse and, as a result, significantly increased the cost of further repairs.
For an experienced TV technician, the socket for the fuse in the power supply unit hastily wrapped in wire, causes sacred awe, horror in the eyes and the understanding that this device cannot be restored quickly and painlessly, that you cannot earn a lot, and you will have to “sit” with it for a long time, looking for changing what in ordinary life is not in the habit of failing. The most unpleasant thing in this case is the unpredictability and lack of logic when searching for defective parts.
Situation analysis and assessment of the factors affecting the occurrence of a malfunction are an integral part of the professional skills that an experienced TV master ... Finding the root cause due to which various components of the television chassis, including fuses, can fail, is the main task of a specialist. You cannot repair, relying on "chance", without having firm confidence that the defect will not recur in the future.
A simple example. Panasonic CRT TV does not turn on. Measurements show that a 56 volt zener diode is broken in the tuner tuning voltage generation circuit, which performs a purely protective function, and its presence or absence in a properly operating chassis is not at all necessary. Due to inexperience, when repairing with your own hands, replacing this part leads to its repeated burnout. If the zener diode is not installed at all, the TV can turn on and work for a while until the line transistor, frame microcircuit or line transformer burns out. The reason for this behavior is in the overestimated voltage that the power supply gives out, and if even deeper, in the loss of the nominal capacity of two electrolytic capacitors of 47 microfarads. in the primary circuit of this block. This is the root cause of all troubles.
There is much more to be said about why the TV won't turn on. This note focuses on the human factor in such a situation and on the fact that always when repairing a TV, as, indeed, any technically complex device, one should look for the cause and eliminate the consequences caused by it. An attempt to restore the TV's performance on its own may not always end in success. You need to be ready for such a turn and think a hundred times before deciding on this step. It may be worth calling a foreman on TV for repair and, accepting a job, pay, first of all, his experience and knowledge, and not the ability to solder and use a tester and a circuit.

Technical description and composition of the HYUNDAI H-LED15V6 TV, panel type and modules used. The composition of the modules.
Panel: LP156WD1 (TL) (A1) // LP156WH4
T-CON: 6870S-0675M LP156WF1-TLA1 CM1722A TPS65149
LED driver (backlight): PCB1D325-13 V1.2
Power Supply (PSU): Adapter 12V
MainBoard: CV181L-A // CV182L-C
IC MainBoard: CPU: MST6E181VS-LS-Z1, Flash: 25Q32B, RAM: W9425G6JH-4, Sound: TDA1517P
Specifications H-LED15V6
HYUNDAI H-LED15V6, like other TVs, it is advisable to start repairing with a careful examination of external and internal elements and modules. Many visible changes in the state of elements make it possible to determine the further direction of troubleshooting and localization of the defect. Charred paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering on the leads of heating elements or transformers can often suggest the causes of a defect and possible consequences.
In the absence of any signs of operability, when the HYUNDAI H-LED15V6 does not turn on and does not signal anything with the control lamps on the panel, there is a possibility of a malfunction of the TV power module. With the same manifestations, the power supply regulator of the control processor on the motherboard may be faulty. When repairing a power supply, it is advisable to start diagnostics with checking the mains fuse and electrolytic capacitors of the filters of the secondary rectifiers of the converter. In the event of a break in the fuse, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply unit. First of all, it is necessary to check the diodes of the rectifier bridge of the mains voltage and the power switch (s) of the converter.
If, when turning on the TV, the image appears and immediately disappears, or is absent initially when turned on, but there is sound and other functions work, there is a high probability of a malfunction of the LED driver (the power converter for the backlight LEDs of the LP156WD1 15.6 HD + panel). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
Complex repair of MB (SSB) is possible only in a service center with the necessary equipment. Checking or replacing CPU elements: MST6E181VS-LS-Z1, Flash: 25Q32B, RAM: W9425G6JH-4, Sound: TDA1517P requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by the warm-up method.
Remember! Attempts of self-repair by users of the HYUNDAI H-LED15V6 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!
The appearance of the MainBoard CV181L-A is shown in the figure below:
The CV181L-A motherboard uses a multifunctional processor MST6M181VS, combined with a scaler (video controller-scaler). It is advisable to start MainBoard repairs by checking the stand-by power supply, which is implemented using a separate 3.3V linear stabilizer. In the operating mode, it is necessary to check the operability of linear stabilizers or voltage converters required to provide power to the processor units: 1.2V, 2.5V, 3.3V. To power the DDR W9425G6JH-4 random access memory, a voltage of 2.5V is required. In the absence of an image, but a working backlight of the display, it is advisable to measure the power supply of the LCD panel 5V or 12V, depending on the type of panel used, directly on the LVDS connector. If the TV does not come out of Stand-by mode, does not respond to the remote control and control buttons, you should check the 3.3V power supply at pin 8 of the SPI FLASH chip, it may be necessary to update its software.
CV181L-A can be used in TVs:
FUSION FLTV-19T9D (Panel TB190B1Z1), FUSION FLTV-22T9D (Panel HM215WU1-500), HYUNDAI H-LED22V16 (Panel M215HW01 VB), HYUNDAI H-LED15V6 (Panel LP156WD1 (TL) (A1)), LC77 SUPRA STL Panel HK215LEDM-BH 1H), SUPRA STV-LC2425WL (Panel M240HW02 V.1), SUPRA STV-LC1677WL (Panel 720p HD 1366 × 768).

Everybody has a TV at home. But it so happens that sometimes this kind and loyal friend refuses to show us his favorite TV shows. In general, the TV is broken. What to do? How to fix a cheap TV? It's very simple - try it yourself, repair the TV with your own hands! Tell me - it's not real, yet how real! Possible malfunctions and methods of their elimination are presented below.
Modern technology, on the one hand, has become more complex, and on the other, more compact and completely repairable. Of course, there are complex malfunctions that are not easy to detect and repair, for which it is necessary to have special equipment and devices, we will not talk about this. We are interested in common faults that can be detected visually and corrected with a screwdriver and a soldering iron. Take any DVD player, LCD TV or display, basically all the circuitry of the device consists of a main board (motherboard) and a power supply unit (power supply). You should not go into the motherboard, you can only harm it without experience, but we will "chicken out" the power supply.
Let's get started. Liquid crystal TV, I do not name the brand, the principle of operation is the same, but in design they differ slightly. Carefully unscrew all the screws on the back panel, put them in a jar or box so as not to lose. Disconnect the back cover. Caution: the front and back panels can be latched together, carefully and carefully try to separate them with a screwdriver. If you opened it successfully, you can see what is inside.

Caution: the front and back panels can be latched together, carefully and carefully try to separate them with a screwdriver. If you opened it successfully, you can see what is inside.
First, we determine what the denomination of the defective parts is.
In our case, two 1000mF x 25V capacitors and two 1000mF x 16V capacitors are faulty. Unfortunately, in our time, manufacturers put capacities at the output of the power supply without a voltage reserve.Therefore, capacitors cannot withstand increased modes, especially during standby operation, without load.
Attention: When changing capacitors, do not mix up the polarity, otherwise you will find out how they explode. When using for the first time, move to a safe distance or cover the power supply with the TV back cover.
Good luck with the repair! Come to our FORUM.
If you have a UPS (uninterruptible power supply), a TV or monitor starts to turn off spontaneously, noise is visible on the screen, the raster size changes, etc., then, in addition to the reasons described, this article often also occurs such as the loss of contact in connectors and elements on the board.
