FLTV-32L28B Specifications

Repair of electronic equipment usually begins with its external examination and diagnostics of a malfunction. In this case, you should inspect all the internal components of the FUSION FLTV-32L28B TV, as well as the external elements of the case. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before starting the necessary measurements. Swollen electrolytic or sintered capacitors, charred resistors, ring cracks in the soldering of the element leads - all this can significantly help the master to determine the causes and consequences of the malfunctions in the TV.

Sometimes the FUSION FLTV-32L28B simply won't turn on. No control lamps on the front panel are on or blinking, the TV does not respond to the remote control and does not emit any sounds or any signs of life when turned on. The most likely cause of a malfunction is the failure of the common power supply module. If it is working properly, it is necessary to check the processor batteries on the SSB (Main Board). It is advisable to start diagnostics of the power supply module by checking the condition of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in a breakdown state in such situations.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (SMPS) it does not fail by itself without reasons that should be looked for by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).

If the FUSION FLTV-32L28B has no picture, but there is sound and the TV is controlled from the remote control, a malfunction in the TH315B051-MD1 panel backlight circuits is likely. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, you need to make sure that the electrolytic capacitors of the rectifier filter supplying the LED driver are in good working order, and check the LEDs by connecting those that are known to be working for diagnostics.
In most cases, there is no backlighting, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or more LEDs do not work in one line, therefore, they are punctured and should be replaced.
To identify an open circuit in the LED lines without disassembling the panel, a current source is required. It is impossible to open the junctions connected in series with a simple multimeter; a voltage of several tens of volts is required.

Diagnostics and repair of the TP.VST59.P83B-65W17 motherboard is carried out by checking the functionality of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Often the MB (SSB) board needs to be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - Cpu: TSUMV59XU, Spi Flash: G25Q32 and replace the failed chips with new ones. Some malfunctions may be associated with the use of BGA soldering technologies in the modern Main Board. Usually such defects are detected by local heating of the chip.
If the TV operates normally from external devices, but does not tune into TV channels, the CDT-3NP5L1-10 tuner may be faulty. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals, as well as the supply of varicaps (30-33V).

Remember! Attempts of self-repair by users of the FUSION FLTV-32L28B TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

In case of malfunctions in the SPI FLASH software produced by Winbond, we recommend that the microcircuit itself be changed to a new one. Sometimes Winbond microcircuits can recover for a while after high-temperature exposure, for example, warming up with a soldering station or a lighter, which is sometimes enough to read its contents.

Almost all TVs from FISION, which use the SPI FLASH chip from WINBOND, need to be replaced by another company or the same company with a new one. Malfunctions that may arise due to a faulty SPI FLASH microcircuit: does not turn on; does not turn on from the duty room; spontaneously turns off, etc.

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:

  1. 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.
  1. Faint, barely noticeable picture - such a breakdown happens with LCD / LCD monitors. The most likely cause of the malfunction: faulty diodes, device backlighting.
  2. 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.
  3. 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:

  1. Open the back cover of the LCD TV with tools.
  2. Disconnect the wires that are connected to the device matrix.
  3. Connect a working light bulb to the contacts.
  4. 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.

  1. The Rubin TV buzzes loudly when connected - most likely, the photodetector needs to be replaced.
  2. The ruby ​​does not turn on, the indicator does not light up - voltage surges in the transistor.
  1. 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.
  2. 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.
  1. The screen does not turn on - there is a problem with the power supply.
  2. 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.

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.

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.

Image - DIY fusion TV repair

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.
