General recommendations for repairing TV LCD
It is advisable to start diagnosing a malfunction of the SHIVAKI STV-32L3 TV, like all others, with an external examination of possible changes, both external and internal elements. Often, by the external signs and nature of some damage, it is possible to draw preliminary conclusions and determine a further algorithm for troubleshooting. 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 SHIVAKI STV-32L3 does not turn on and does not signal anything with the control lights on the panel, the power supply module FSP205-4E01 is most likely faulty. In this case, first of all, it is necessary to check the fuse at the mains input. 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 N-FET converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
If a breakdown of the power switch of the flyback converter of the power supply unit is detected, it should be remembered that it does not fail without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, PWM controller NCP1014 TNY264 FAN7529MX (8) FAN7530 L6598 (16) , which can be checked only by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
In cases where the Power Factor Corrector (PFC) is used in the power supply, troubleshooting can be a bit more complicated.
If the SHIVAKI STV-32L3 TV does not have an image, but there is sound, the malfunction should be sought in the backlight power converter (inverter). It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overstated ESR.
Repair of the inverter HS-EE32WL-M REV 0.1 6632L-0342B 6632L-0343B is complicated by the fact that in case of any malfunction or emergency, even if the lamps are unevenly worn, protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
It should be remembered that in such cases there is a risk of failure of the power elements of the inverter and to take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.

Owners and users of the SHIVAKI STV-32L3 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!

PSU Advanced
The STV-32L3 model uses the FSP205-4E01 power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a boost converter based on the FAN7530 PWM controller, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes, when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.

General recommendations for repairing TV LCD
Repair of the SHIVAKI STV-32L6 TV is advisable to start with an external examination of all its constituent elements, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. It often happens that some damage to elements or connections will help determine the correct direction of troubleshooting and localization of the defect. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
In the case when the STV-32L6 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, most likely in this case the power supply module is faulty. It is advisable to start the troubleshooting of the power supply module by checking the mains fuse. If it is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and the power switch of the converter, which are often found in breakdown conditions in such situations.
In most cases, a breakdown of the N-Fet converter key does 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 an active Power Factor Corrector (PFC) is used in the power module circuitry, it is sometimes more difficult to troubleshoot. Knowledge, experience, intuition and skills in such cases have a great advantage for a successful repair.
If the SHIVAKI STV-32L6 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. 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 inverter itself, including in the secondary rectifier of the main PSU.
Repairing the inverter is difficult because in case of any malfunction or emergency, even with uneven wear of the lamps, a protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
In cases of attempts to repair the motherboard L2M015 (02) 2009.09.06, it is necessary to check the operability of the power supply circuits of the microcircuits and, if possible, update the software (software). 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 - MSD106CHL-LF-Z1, 25L3205DM2C, T315HW02 V.7, IJ99F (6), TMDS251, tuner DTI1-E4I2RH 9916FI and replace the failed chips with new ones.

General recommendations for repairing TV LCD
It is advisable to start the diagnostics of a malfunction of the SHIVAKI STV-26L2 KALININGRAD TV, like all others, with an external examination of possible changes, both external and internal elements. Any external damage can sometimes prompt the repairman to take further steps to determine the malfunction of the TV and localize the defect. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
Malfunctions of the MLT070A power supply module can be expressed in different ways, for example, SHIVAKI STV-26L2 KALININGRAD does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. When diagnosing and repairing the power supply, first of all, it is necessary to 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 or power switch 20N60, 9N50, 5N60.
It should be remembered that the N-FET keys used in flyback converters rarely fail for no reason that must be sought by checking other elements of the circuit. 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 ML4800C6, LM358, 20N60 can also cause a breakdown of the power switch of the converter.
It is somewhat more difficult to look for a malfunction in the converter of the power module with an active KKM (power factor corrector).
If the SHIVAKI STV-26L2 KALININGRAD does not have an image, but there is sound and the TV is controlled from the remote control, a malfunction in the display backlight nodes is likely. The lamps or the power converter - inverter may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the inverter, and check the LCD lamps by connecting external and obviously serviceable for diagnosis to the connectors.
In most cases, the diagnosis and repair of the VT71008.90 Logah REV: 0 inverter is difficult due to the organization of protection, which turns it off in emergency cases to avoid fires during short circuits or open circuits in high voltage circuits and during lamp depressurization. Often, repairmen block the protection circuits in order to make the necessary measurements at the inverter control points to identify the causes of the defect.
All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
On the tun TDQ6F6T1260 motherboard, in case of a malfunction, you should first check the operation of all power supply stabilizers of the microcircuits and, if necessary, update the software (software). 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 - MST6151A, TDA12063H, AN17820N, K4S161622H-UC60, and replace failed chips with new ones.

General recommendations for repairing TV LCD
Repair of the SHIVAKI STV-26L6 TV is better to start with a thorough external inspection and diagnosis of the malfunction. It is advisable to carefully examine the internal and external components. Many visible signs make it possible to determine the future direction of troubleshooting and localization of the defect. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
Sometimes the SHIVAKI STV-26L6 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 common LKL- power supply module. When diagnosing and repairing the LKL-power supply unit, it is first necessary to check the fuse, and if it breaks, the power switch and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
It should be remembered that the N-FET keys used in flyback converters rarely fail for no reason that must be sought by checking other elements of the circuit. 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 can also cause a breakdown of the power switch of the converter.
Diagnostics of power modules with a Power Factor Corrector (CMC) is somewhat more complicated and requires a more detailed approach.
If the SHIVAKI STV-26L6 TV does not have an image, but there is sound, the malfunction should be sought in the power converter of the backlight (inverter). It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overstated ESR.
Repair of the inverter can often be somewhat complicated by the use of special protection circuits, which are designed to disconnect it in emergency cases for fire safety during depressurization of lamps, or short circuits or breaks in high-voltage circuits and connections. Sometimes it becomes necessary for diagnostic purposes to block the protection circuits in order to be able to make the necessary measurements at the control points of the circuit.
In these cases, special care must be taken in view of the risk of failure of the power elements. After completing all repair work, it is imperative to restore the protection circuits for full and safe further operation of the TV by the user.
On the motherboard, in case of a malfunction, it is first of all necessary to check the operability of all power stabilizers of the 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) - MSD106CHL-LF-Z1, KH25L3206E.

SHIVAKI STV-32L2
General recommendations for repairing TV LCD
Like any other TV, it is advisable to start the SHIVAKI STV-32L2 repair with an external examination of the visible changes in the external and internal elements. Many visible signs make it possible to determine the future direction of troubleshooting and localization of the defect. Electrolytic capacitors of filters with a swollen casing, as well as ring cracks formed in the soldered leads of heating elements, or a layer of coal on burnt resistors sometimes tell the repairman the causes of the malfunction and possible consequences.
In the absence of any signs of operability, when the SHIVAKI STV-32L2 KALININGRAD does not turn on and does not signal anything with the control lights on the panel, the ML4800SC power supply module is most likely faulty. The diagnostics of the power supply should always be started by checking the fuse and, if it is broken, it is first necessary to check the rectifier bridge diodes and the power switch for the possibility of an avalanche or thermal breakdown.
It should be remembered that the N-FET keys used in flyback converters rarely fail for no reason that must be sought by checking other elements of the circuit. 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 FAN7601 PWM controller chip can also cause a breakdown of the power switch of the converter.
If the power module uses an active KKM circuit (power factor control), troubleshooting is somewhat more complicated.
Sometimes the SHIVAKI STV-32L2 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the backlight converter, or of the lamps themselves, which can be checked by replacement. In such cases, it is necessary to verify the serviceability of all electrolytic capacitors of the filter according to the power supply of the inverter itself, including in the power supply unit (power supply unit).
Repair of the inverter 4H.V0708.381 / B1 mod. V070 is complicated by the fact that in case of any malfunction or emergency, even with uneven wear of the lamps, a protection is triggered, which turns it off for fire safety purposes. Diagnostics become impossible and protection needs to be disabled.
In such cases, the risk of failure of the power elements of the inverter is most likely, and special care is required during work, and after their completion, it is necessary to restore the protection circuit for further safe operation of the TV by the owner in normal mode.
Repair of the motherboard must begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM. 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 - MST9U88L-LF, 24LC32AI, TDA7297, tun TDQ-6F6 / T126D (TDA6509ATT) and replace failed chips with new ones.

SHIVAKI STV-22L6
General recommendations for repairing TV LCD
Like any other TV, it is advisable to start the SHIVAKI STV-22L6 repair with an external examination of the visible changes in the external and internal elements. Often, for certain external signs, the repairman can draw some conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing the defect. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
In cases where the SHIVAKI STV-22L6 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, what it happens much less often - there is no processor power on the motherboard. If the mains fuse is broken in the power supply, in most cases a breakdown of the power switch 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.
The reasons for the breakdown of the power switch of the flyback converter of the power module 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 breakage of the resistors in its bundle.
When using the Active Power Factor Correction (CMC) circuitry in the power module, the search for faulty elements is somewhat more complicated.
If there is no image when you turn on the SHIVAKI STV-22L6, or it appears for a second and disappears completely, but there is sound, most likely either the backlight lamps or their power converter (inverter) are faulty. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
When repairing the inverter, it is often necessary for diagnostics to turn off the protection, which, for the purpose of fire safety, turns it off in any emergency situation, for example, during a malfunction or uneven wear of the lamps, which makes it difficult to find a defect.
Turning off the protection for diagnostic purposes, it must be remembered that in this case there is a risk of failure of the power elements of the inverter. Upon completion of the diagnosis, all regular protection circuits should be restored.
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, to repair the MB board (SSB), it may be necessary to replace the chips - EN25F40, 24C32, SA7454, MX25L3205, FT24C32A with new or obviously working ones.

It should be remembered! Attempts to repair the SHIVAKI STV-22L6 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

General recommendations for repairing TV LCD
It is advisable to start diagnosing the malfunction of the SHIVAKI STV-20L3 TV, like all others, with an external examination of possible changes, both external and internal elements. Visible damage to elements can sometimes suggest further directions for finding a defect before starting the necessary measurements. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a hint in the assumptions about the causes and consequences of the malfunction.
Sometimes the SHIVAKI STV-20L3 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 Haider HDAD60W102-OF REV2.1 CCE-VOE166702 common power supply module. If the mains fuse is broken in the power supply, in most cases a breakdown of the power switch 6N52JP02 (SO8) 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.
It should be remembered that the N-FET keys used in flyback converters rarely fail for no reason that must be sought by checking other elements of the circuit. 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 LD7552BP (SO8) STK0766 can also cause a breakdown of the power switch of the converter.
In cases where the Power Factor Corrector (PFC) is used in the power supply, troubleshooting can be a bit more complicated.
Sometimes the SHIVAKI STV-20L3 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the backlight converter, or of the lamps themselves, which can be checked by replacement. In such cases, it is necessary to verify the serviceability of all electrolytic capacitors of the filter according to the power supply of the inverter itself, including in the power supply unit (power supply unit).
Diagnostics of the Haider IVA20601D REV03 PC40003J inverter --- 1CG CCE-VOE166702 can be difficult due to the protection being triggered by the designers to prevent negative consequences or fires in emergency cases, for example, during short circuits or open circuits in the lamp power supply circuit, as well as their possible depressurization. To make the necessary measurements at control points or to take the necessary waveforms, repairmen have to block the protection circuits in order to be able to diagnose.
It should be remembered that when the protection is turned off, there is always a risk of failure of the power elements of the inverter during diagnosis. After repair, it is necessary to restore all standard converter protection circuits.
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). If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - TDA15021H / N1C00, 24C16AN, MST9010SA-LF, AN17825A, 74HC153D, KF9650. Defective components should be replaced.

General recommendations for repairing TV LCD
Repair of the SHIVAKI STV-20L2 TV is advisable to start with an external examination of all its constituent elements, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. Any external damage can sometimes prompt the repairman to take further steps to determine the malfunction of the TV and localize the defect. In some cases, faulty elements can be seen with the naked eye, for example, charred 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.
In cases when the SHIVAKI STV-20L2 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 when turning on, the AC adapter SAWA power supply module is most likely to be faulty -01-483 (12v / 5A) or BPD0023A - DZG or, which is much less common, there is no processor power on the motherboard. The diagnostics of the power supply should always be started by checking the fuse and, if it is broken, the first thing to do is to check the rectifier bridge diodes and the power switch BA6N62 plan 8n (4606). BA7K28 for the probability of an avalanche or thermal breakdown.
It should be borne in mind that in the repair practice it is extremely rare that key transistors of the N-FET type fail for no reason that should be looked for by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, either dried electrolytic capacitors or dangling resistors of the primary circuit of the PSU, involved in the stabilization process. In this case, all semiconductor elements of the strapping of the BIT3106A pit PWM controller chip are subject to verification. SG6841SZ 2AO7512 (8H), which is preferably checked by replacement.
If an active Power Factor Corrector (PFC) is used in the power module circuitry, it is sometimes more difficult to troubleshoot. Knowledge, experience, intuition and skills in such cases have a great advantage for a successful repair.
In cases where the SHIVAKI STV-20L2 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 inverter (converter for powering the backlight). When you turn on the TV, the image may appear briefly and immediately disappear. It must be borne in mind that with such manifestations, the lamps themselves also fail, the malfunction of which can be detected by replacement, by connecting to the connectors for diagnostics that are known to be serviceable and suitable in power.
When repairing the SFP2066E_Ver1.0 inverter, it is often necessary to disable the protection for diagnostics, which, for the purpose of fire safety, turns it off in any emergency situation, for example, during a malfunction or uneven wear of the lamps, which makes it difficult to find a defect.
In such cases, the risk of failure of the power elements of the inverter is most likely, and special care is required during work, and after their completion, it is necessary to restore the protection circuit for further safe operation of the TV by the owner in normal mode.
Diagnosis and repair of the motherboard SHFA060213535 is carried out by checking the performance of power stabilizers or updating the software (software).

Owners and users of the SHIVAKI STV-20L2 TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences, which can lead to complete non-repairability of the device!

General recommendations for repairing TV LCD
It is advisable to start repairing a SHIVAKI TV-505D TV, like any others, with an examination of the internal and external visible physical visual changes. Often, for certain external signs, the repairman can draw some conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing the defect. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
If the TV does not turn on, no indicators on its front panel are lit or blinking. 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, but this happens much less often. The diagnostics of the power supply should always be started by checking the fuse and, if it is broken, it is first necessary to check the rectifier bridge diodes and the power switch for the possibility of an avalanche or thermal breakdown.
It should be remembered that the N-FET keys used in flyback converters rarely fail for no reason that must be sought by checking other elements of the circuit. 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 can also cause a breakdown of the power switch of the converter.
If the power module uses an active KKM circuit (power factor control), troubleshooting is somewhat more complicated.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but there is sound and other functions work, there is a high probability of a malfunction of the inverter (power converter for the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the inverter should be checked.
When repairing the inverter, it is often necessary for diagnostics to turn off the protection, which, for the purpose of fire safety, turns it off in any emergency situation, for example, during a malfunction or uneven wear of the lamps, which makes it difficult to find a defect.
When diagnosing with the protection off, special precautions must be taken, because there is a risk of failure of the power elements of the inverter. After the diagnosis, it is imperative to restore the protection circuits for the inverter to operate normally.

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 attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - MST726C-LF P10-100GCP (EN25P10) SA7496LS TDA9886TS which may require replacement with new ones.

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.

General repair guidelines for TV LCD LED
Possible manifestations of defects
- The SHIVAKI STV-55LED17 TV does not turn on and does not show any signs of turning on, it does not respond to the control buttons or to the remote control.
In this case, first of all, you should check the operability of the main power source - AC / DC network voltage converter, all of whose elements are located on the MainBoard TP.S512.PC821 board. It is necessary to measure its output voltages, and in case of their absence, check the serviceability of power switches (MDF13N50B, 70R900P) of converters and rectifier diodes for the probability of short circuit.
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.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback circuits (OOS) of stabilization. PWM controllers (PWM) NCP1607B, LD5530, if they do not have visible damage to the case and open fault between the terminals, are usually checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The 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 the 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 an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights constantly or blinks.
Repair or diagnostics of the TP.S512.PC821 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - CPU: S2T512, SPI FLASH: W25Q64BV, Audio: TPA3110D2, 1117 with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltages at the terminals of the R840 & XF-3SDT-H tuner. It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.

We recommend the owners of the STV-55LED17 TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

Possible manifestations of defects
- The SHIVAKI STV-55LED15 TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
Typically, with such manifestations, the defect is caused by faulty elements in the MIP550D-CX2 main power module. It is necessary to measure its output voltages, and in case of their absence, check the operability of the power switches of the converters and rectifier diodes for the probability of a short circuit.
In the event of breakdowns in the secondary circuits of the converter, it can usually fail in short circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most often breaks.
Mos-Fet power switches, used in switching power supplies, sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode or create an excess of the maximum permissible parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers, in the absence of visible damage or frank short-circuit between the terminals, are checked by replacing with new, or obviously working.
- 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.

Possible manifestations of defects
- The SHIVAKI STV-50LED13 TV does not turn on. There are no signs of operability. The indicators on the front panel do not light or flash, the TV does not respond to the remote control and control buttons.
First of all, in such cases, you should verify the operability of the common switching power supply (IIP) - AC / DC voltage converter of the mains voltage. All source elements, including the PFC circuit and LED drivers in this TV model are located on the MainBoard TP.S512.PC821 main board. It is necessary to measure all the output voltages of the source, and if they are absent, you should check the power switches and rectifier diodes of the converters for a short circuit probability.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the mains fuse and, less often, the current sensor at the source of the key are most often cut off.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM circuits NCP1607, LD5530, LD7750 are usually checked by replacing with new, or obviously working.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
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 LED line without disassembling the panel with a simple multimeter. The 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.

If necessary, update or replace the software (software). Sometimes they require checking or replacing (if necessary) the elements of the MainBoard board - S2T512, W25Q64BV, TPA3110D2. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
The malfunction of the tuner R840 - XF-3SDT-H, T3 / 1 R 1/613 is established after checking the software and all the supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
