ELENBERG LTV-2231
General recommendations for repairing TV LCD
Possible manifestations of defects
- The ELENBERG LTV-2231 TV does not turn on and does not show any signs of turning on. There are no reactions to the control buttons or the remote control.
In most of these cases, the JSI-220401B main switching power supply fails. It is necessary to measure the secondary output voltage, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM chip P22M OB2269S (SG6841S) can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
These manifestations can be triggered by the power module, or by inverter defects, as well as by the distortion of the currents in the lamps due to their uneven wear. If all the electrolytic capacitors of the filter according to the inverter power supply are serviceable, you should make sure that the lamps are in good working condition, then you need to check the converter keys and the secondary windings of the transformers.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- 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.
Repairing or diagnosing a QINGJLA 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). In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - MST9E19A-LF 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 AFT1 / 3100G tuner, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary voltage levels and impulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.

Attention to users! Self-repair of the ELENBERG LTV-2231 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

Possible malfunctions
- The ELENBERG CTV-1540 TV does not turn on at all. There is no reaction to the remote control or to the control buttons from the front panel. Indicator lights do not light or flash.
In such cases, the fault should be sought first in the Adapter power module.
This TV model is equipped with an external power adapter type Adapter 24V 4A, which the owner can purchase independently, and repairing it may not always be advisable, however, sometimes there is some sense in opening it and eliminating simple typical defects typical of IIPS. It is necessary to verify the presence of secondary voltages and, if they are absent, check the power switches and rectifier diodes for a short circuit.
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 main 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 the excess of maximum current or voltage values. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may be PWM (PWM). It is checked only by replacement with a known good one.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
These manifestations can be triggered by the power module, or by inverter defects, as well as by the distortion of the currents in the lamps due to their uneven wear.

The MLT-268A power supply module is made using the Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced by the device into the mains. The PFC assembly is a Step-Up Converter based on the FAN7529 PWM controller, which evenly distributes high-frequency pulses of the charging current of the electrolytic capacitor of the rectifier filter of the mains voltage over a period of 50 Hz. The current of its charge in this case will already be determined not by its reactance (usually 10-30 ohms for the network frequency), but by the elements of the converter. As a result, a change in the amplitude of the pulses (envelope) of the consumed current of the converter will repeat the shape and phase of the input sinusoidal voltage. The availability of an increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.

 According to the conditions of compliance with modern world standards for household switching power supplies, the MLT-268A module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the FAN7529 PWM controller. The reactance of the electrolytic capacitor of the line filter at a frequency of 50-60 Hz is usually not more than 20-30 ohms and its charge directly from the network through open diodes could reach tens of amperes per pulse if no filtering were applied.
As a result of the PFC conversion, an increased voltage on the capacitor (about 380V) cannot directly open the rectifier diodes, on the anode of which the voltage will always be slightly less (about 300V) and then its charging current will always be limited by the elements of the PWM controller. As a result, the envelope of the high-frequency pulses of the consumed current will repeat the shape and phase of the input sinusoidal voltage. The presence of an increased voltage (+ 380V) on the network capacitor indicates the serviceability of the PFC node.

- The ELENBERG LVD-1902 TV does not turn on and does not show any signs of operability at all. There is no reaction to either the remote control or the front panel control buttons.
With such manifestations, a malfunction is likely to be detected in the 2956C power supply module. It is necessary to measure its secondary output voltages, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
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 main fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM chip CM0765R can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or inverter. If all the electrolytic capacitors of the filter according to the power supply of the inverter are working, make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- 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 3302CV5.3 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace 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 elements FLI8125, FSAV330, AT49F040A (Flash), TPA3008 (Sound). BGA chip malfunctions are usually easy to detect by warming up.
Before replacing the tuner M09WPP-1P-E TCL 071029 08E 07, if there is no tuning for the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus

General repair guidelines for TV LCD LED
Repair of any electronic device, in particular Elenberg with the 2973C V5.0 chassis, is advisable to start with an external examination of the internal and external elements. Visible damage to elements can often indicate the direction of a defect search.
If the LVD-1502 TV does not turn on at all and does not make any sounds when it is turned on, no indicators light up or blink on the front panel - there is a high probability of a malfunction in the power module, which is designed as a separate device and is included in the TV set. First of all, in the power supply unit, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken in the power supply, a breakdown of the power switch is possible, which can be integrated with the PWM controller. In this case, you should check the rectifier bridge diodes, as well as the electrolytic capacitor of the rectifier filter.
Typically, power switches in switching power supplies are reliable enough and rarely fail for no reason to look for when checking other components of the circuit. The PWM controller chip is checked by replacing with a known-good one.
If, when you turn on the TV, the image is missing, or appears and immediately disappears, but the sound is there and other functions work, there is a possibility of a malfunction of the LED driver (power converter for the backlight). In such cases, it is necessary to check the lamps, the LED driver and the general power supply module, in which you should pay attention to the electrolytic capacitors of the rectifier filter supplying the LED driver.
When diagnosing a malfunction of the LED backlight driver with disabled protection, special care must be taken, there is a risk of failure of the power elements of the LED driver. After the diagnosis, it is imperative to restore the protection circuits for the LED driver to operate normally.
If the Main Board 2973C V5.0 is faulty, you should first 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. In cases of complex MB repairs and with the necessary skills and equipment, sometimes it may be necessary to replace microchips.

Attention to the owners! Attempts to self-repair TVs without appropriate qualifications are not recommended by the manufacturer and can lead to serious negative consequences up to complete non-repairability!

General repair guidelines for TV LCD LED
Television ELENBERG LE236N59W, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. 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.
If the ELENBERG LE236N59W does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a malfunction of the PCB power supply module - MP113-W. In some cases, only the processor power regulator 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 cut off 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.
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, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but the sound is there and other functions work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the HM236WU-100 panel). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
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 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 the CV59L-C motherboard is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, as well as, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
Board repair and replacement of Cpu: TSUMV59XE-Z1 chips, Spi Flash: 25Q32, Audio: YD1517 are made with the necessary equipment, and the corresponding hardware base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.

Attention! Users and owners of LE236N59W TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

General repair guidelines for TV LCD LED
Possible malfunctions
- The ELENBERG E39Q2510A TV does not turn on and does not show any signs of turning on at all. There are no reactions to the control buttons or the remote control.
In the vast majority of such cases, a malfunction is detected in the HS100D-1MF12 power supply module. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary first of all to check the power switches and rectifier diodes for a possible partial or complete breakdown.
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 main 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 the excess of maximum current or voltage values. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may be PWM (PWM) 2A1178, NCS1002A, NCP1271A. It is checked only by replacement with a known good one.
- 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 turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the JUG7.820.1358 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). In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - AT25DF321A, TPA3100D2, IT6633E-P with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
In cases where there is no 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 R620D 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.

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.
