General repair guidelines for TV LCD LED
If the UE40J5530AU 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. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
The breakdown of the power switch of the pulse converter is often triggered by other elements, for example, in the stabilization or control circuits of this switch, as well as by the damper elements in its drain and TPI winding.
Sometimes the SAMSUNG UE40J5530AU TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a possibility of a malfunction of the LED driver - the power converter of the backlight LEDs of the CY-GJ040BGSV5V panel, or an open circuit in the LED circuit is possible. In such cases, first of all, it is necessary to verify the operability of the electrolytic capacitors of the filter by supplying the backlight unit.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
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. 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.
If the motherboard BN41-02353B BN94-09121B is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, and also, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
In some cases, they require checking or replacing (if necessary) the elements of the MB board (SSB) - SPI Flash: W25Q40; EEPROM: 24C512. 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 tuner BN40-00318B, first of all, you need 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.
Once again, remind users! Attempts to self-repair a SAMSUNG UE40J5530AU TV without the appropriate qualifications and experience can lead to its complete non-repairability!

The appearance of the power supply
Main features of the SAMSUNG UE40J5530AU device:
Installed matrix (LED panel) CY-GJ040BGSV5V.
The matrix control uses the Timing Controller (T-CON) RUNTK5538TP.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE40J5530AU TV are generated by the BN44-00703G power supply module or its analogs using S3051 (PFC), FA6A20 (PWM resonant) microcircuits and 13N60M2 (PFC), 14NM50N type power switches.
MainBoard - the main board (motherboard) is a BN41-02353B module, using SPI Flash chips: W25Q40; EEPROM: 24C512 and others.
The tuner BN40-00318B provides the reception of television programs and tuning to channels.
