General repair guidelines for TV LCD LED
The FUSION FLTV-19L16B TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
Sometimes the FUSION FLTV-19L16B TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the LKP-LP055 common power module. If it is working properly, it is necessary to check the processor batteries on the SSB (Main Board). When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself for no reason that should be sought 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-19L16B has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the M185B3-PA1 panel, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
When trying to identify a break in the LED lines, it should be borne in mind that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
The CV181L-Y motherboard must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary.
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - 25Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If there is no reception of television channels, but the TV is working properly from external devices, first of all it is necessary to check the voltage of the varicaps of the tuner CDT-3SP5I2-37, which is usually within 30-33V, as well as other supply voltages at the terminals of the tuner.

Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.

FIRMWARE FOR SPI FLASH  ----------->   FUSION FLTV-19L16B V1L06, Main: CV181L-Y, Panel: M185B3-PA1

 In case of failures in Winbond's SPI FLASH software, we recommend that you replace the chip itself with a new one. Sometimes Winbond microcircuits can recover for some time after high-temperature exposure, for example, heating with a soldering station or a lighter, which is sometimes enough to read its contents.

To reduce the backlight current in LED drivers with a PWM controller MP3389EF (MP3389), or its analogue OB3362VP (28 pin), it is necessary to proportionally increase the total resistance of the resistors from terminal 9 (ISET) to the housing. The maximum current in each of the 12 channels (in milliamps) for the resistance Rset (in kilo-ohms) is determined from the ratio 1000 * 1.22V / Rset. With a parallel connection of channels, the currents are added up.

General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-19L31B TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Based on visible external changes in the state of the components, it is usually possible to determine the further direction of troubleshooting and localization of the defect before making the necessary measurements. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
Sometimes the FUSION FLTV-19L31B TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the HKL-190401 common power module. If it is working properly, it is necessary to check the processor batteries on the SSB (Main Board). When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
Power switches in switching power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one.
In cases where the FUSION FLTV-19L31B TV has lost its image, and the sound is there and all the other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the HK185WLEDM-HH75H panel). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
If the T.VST59.11 motherboard is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - CPU: TSUMV59XE-Z1, FLASH: 25Q32. Defective components should be replaced.

Attention to users! Independent repair of the FUSION FLTV-19L31B TV without the appropriate qualifications and experience can lead to its complete non-repairability!

 In case of failures in the software of SPI FLASH microcircuits made by Winbond, they can for some time restore their working capacity after temperature exposure - heating by a hairdryer of a soldering station or even a lighter. Usually this is enough to read the regular contents of the software. In such cases, the chip must be replaced with a new one.

To reduce the backlight current in LED drivers with an OB3362RP (TSOP16) controller, increase the total resistance of the resistors from pin 5 (ISET) to the chassis. The maximum current in each of the four channels (in milliamperes) for the Rset resistor (in kilo-ohms) is determined from the ratio 3000 * 1.2V / Rset.

Repair of the FUSION FLTV-19T9D TV should begin with a careful external examination of all its components and modules. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
In cases when the FUSION FLTV-19T9D TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the power module is most likely faulty or there is no power processor on the motherboard (a typical defect of some models of FUSION TVs). In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip may also cause a breakdown of the power switch of the converter.
If the FUSION FLTV-19T9D TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the TB190B1Z1 panel is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the BP (power supply) for an overstated ESR.
In most cases of lack of backlight, there is a need to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its Cpu: MST6M181VS, Spi Flash: 25Q32, Ram: Winbond W2925G6JH-4, Audio: YD1517P, and other possible malfunctioning components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
If you suspect a malfunction of the AFT7 / W110G QINGJIA tuner, first of all, you need to make sure that the voltage of the varicaps (30-33V) is on the corresponding output of the tuner, as well as other voltage supplying it.

Owners and users of the FUSION FLTV-19T9D TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. In some cases, faulty elements can be seen with the naked eye, for example, carbonized resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
If the TV does not turn on, no indicators on its front panel light or blink. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain probability that the power module is defective and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of processor power, which is typical for certain FUSION models. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip may also cause a breakdown of the power switch of the converter.
If the FUSION FLTV-22C10 does not have an image, but there is sound, the backlight LEDs of the M215HTN01.3 panel or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
Diagnostics and repair of the TP VST59.PA671 motherboard is carried out by checking the operability of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: TSUMV59XE-Z1, SPI: FLASH W25Q32BV and replace failed chips with new ones. Some malfunctions can be associated with the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.

We recommend the owners of the FLTV-22C10 TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

General repair guidelines for TV LCD LED
FUSION FLTV-22L31B, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
In cases when the FUSION FLTV-22L31B TV does not turn on, does not respond to the remote control and buttons, any indicators on the front panel do not light up or blink and there are no sounds and no signs of operability at all, the power module is most likely faulty or there is no power processor on the motherboard (a typical defect of some models of FUSION TVs). Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the network rectifier, as well as the large electrolytic capacitor of the filter of the network rectifier.
Power switches in switching power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one.
In cases where the FUSION FLTV-22L31B TV has lost an image, and the sound is there and all the other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the panel backlight LEDs). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
An open in the LED lines connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - SPI FLASH: GD25Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.

Once again, remind users! Attempts to independently repair the FUSION FLTV-22L31B TV without the appropriate qualifications and experience can lead to its complete non-repairability!

General repair guidelines for TV LCD LED
Possible manifestations of defects
- FUSION FLTV-22LF31B does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
In such cases, the HKL-240101 power supply is usually faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the operability of the power switches (7N65FB) of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) OB2273 (PWM SOT23-6), in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, there is sound, it responds to the remote control. Or the image may appear for a second when turned on and immediately disappears.
As a rule, in such cases there is no display backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to detect a break in the line of LEDs without disassembling the panel with a simple multimeter. LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED if you connect probes in the forward direction to it (red probe to the anode, black to the cathode). In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as a health indicator. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The indicator blinks or lights up constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the CV59L-E motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Sometimes it is necessary to check or replace (if necessary) the elements of the MainBoard - CPU: TSUMV59XU-Z1 EEPROM: 24Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If you suspect a malfunction of the CDT-3NP5I1-10 tuner, first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.

Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.

General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-22T22 TV should begin with a careful external examination of all its components and modules. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. If ring cracks are detected in the soldered terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the FLTV-22T22 TV does not turn on, does not make any sounds when it is turned on, and also no indicators light up or blink on the front panel, there is a high probability of a malfunction in the power supply module. In some cases, there may be a malfunction only in standby power. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If the FUSION FLTV-22T22 has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the 720p HD, 1366x768 panel, or their power converter - LED driver. Sometimes, when turned on, the image appears and immediately disappears. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
In case of breaks in the LED circuit, a complete disassembly of the panel is required, the LEDs are checked for an open circuit, as well as the reliability of the connections in the connectors and rations of the terminals.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
On the CV9202L-T motherboard, in case of a malfunction, you should first check the performance of all the stabilizers and power converters of the microcircuits, and also, if necessary, update the software (software).
Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the SPI Flash elements: W25Q64FVSIG; SOUND: YD1517P; . BGA chip malfunctions are usually easy to detect by warming up.
The malfunction of the tuner ST03WS-2A-E is established after checking the software and all supply voltages at its terminals.

FUSION FLTV-22T9
General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-22T9 TV should begin with a careful external examination of all its components and modules. Based on visible external changes in the state of the components, it is usually possible to determine the further direction of troubleshooting and localization of the defect before making the necessary measurements. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in soldering will help the master to guess the causes and possible consequences of the malfunction.
In the absence of any signs of operability, when the FUSION FLTV-22T9 does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV power module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the network rectifier, as well as the large electrolytic capacitor of the filter of the network rectifier.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its wiring.
If there is no image when you turn on the FUSION FLTV-22T9, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the TB215WU3 panel, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
In most cases of lack of illumination, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
When trying to identify a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
Diagnostics and repair of the CV182L_B motherboard is carried out by checking the operability of the stabilizers or power converters of the module chips. In some cases, a software update is required.
In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - 25Q32BVSIG, YD1517P with new or obviously good ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
If you suspect a malfunction of the tuner CDT-3SP5I2-37, first of all, you need to make sure that the voltage of the varicaps (30-33V) is present on the corresponding output of the tuner, as well as other voltage supplying it.

Remember! Attempts to self-repair by users of the FUSION FLTV-22T9 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the FUSION FLTV-22T9D TV, as well as the external elements of the case. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. Experienced repairmen are often aware of the causes of the defect and the possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
In the absence of any signs of operability, when the FUSION FLTV-22T9D does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV power module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is checked by replacing it with a known good one.
If the FUSION FLTV-22T9D has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the HM215WU1-500 panel, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
If the motherboard CV181L-A is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
Board repair and replacement of CPU chips: MST6M181 / 182, main DVD AL10-M-64, CPU DVD MT1389DE, SPI Flash DVD EN25F80, laser HOP-120X are made with the necessary equipment, and the corresponding element base. Malfunctions associated with the application of the soldering technology of the BGA processor can be localized by the heating method.

General repair guidelines for TV LCD LED
The FUSION FLTV-22W6 TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and determine the direction of further troubleshooting even before the necessary measurements are taken. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the FLTV-22W6 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, there may be a malfunction only in standby power. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the binding of the PWM controller microcircuit are subject to verification, which it is desirable to verify by replacement.
If there is no image when you turn on the FUSION FLTV-22W6, or it appears and immediately disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the CLAA215FA panel, or in their power converter.
In most cases of lack of illumination, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up one LED slightly if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the SPI Flash elements: EN25T80_U11; EEPROM: 24C32_U13; . BGA chip malfunctions are usually easy to detect by warming up.
If the TV works normally from external devices, but does not tune into television channels, the tuner ET6T1E-LF-108W-A may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals. Sometimes the cause of the inoperability of the tuner may be a software failure.

Attention to the owners! Attempts to self-repair the FUSION FLTV-22W6 TV are not recommended by the manufacturer and can lead to serious negative consequences!

Possible manifestations of defects
- FUSION FLTV-22W8 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
Often in such cases, the 569KN0120D power module is faulty. It is necessary to measure its output supply voltage, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode, or cause the maximum current or voltage to be exceeded. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM), in the absence of external damage and a short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
In some of these cases, the malfunction is caused by a lack of backlighting on the display. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required. Then it is necessary to open the panel and check each LED separately with a multimeter. If the capabilities of your multimeter do not allow you to open the LED in the forward direction or dual LEd are used, then the PN junction of the emergency zener diode can indirectly serve as a health indicator. In case of LED-a malfunction, the zener diode PN junction will either be cut off or broken into short-circuit.
- The indicator blinks or lights up constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the 569KC0201A motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Board repair and chip replacement SPI FLASH: MX25L3206E are made with the necessary equipment, and the corresponding hardware base. Faults associated with the use of BGA processor soldering technology can be localized by the heating method.
If there is no reception of television channels, but the TV works properly from external devices, first of all it is necessary to check the voltage of the tuner F41CT-2B-E and update the software. The pulses from the I2C bus must be monitored using an oscilloscope.

Once again, remind users! Attempts to independently repair the FUSION FLTV-22W8 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!
