General repair guidelines for TV LCD LED
Sometimes the SAMSUNG UE40J6390 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 a failure of the common power module BN44-00703A L48S1_ESM. If it is working properly, you must check the standby batteries on the Main Board. 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.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the FA6Axx PWM controller chip (FA5760N) itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If there is no image when you turn on the SAMSUNG UE40J6390, or it appears and immediately disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the CY-GH040CSLV1V panel, or in the LED node of the driver-converter of their power supply.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source. By opening the panel, each LED can be checked separately. Usually, Chinese multimeters light up a single 3-volt LED, if you connect probes in the forward direction to it. 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.
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).
Before replacing the tuner BN40-00318B, if there is no tuning to 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
Once again, remind users! Attempts to self-repair a SAMSUNG UE40J6390 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 UE40J6390 device:
Installed matrix (LED panel) CY-GH040CSLV1V.
The matrix control uses the Timing Controller (T-CON) BN41-02110A.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller. As power elements of the LED driver, keys of the AOD5N40 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE40J6390 television are generated by the BN44-00703A power supply module or its analogs using SEM3051 (PFC), FA6A01N (PWM resonant) microcircuits and 13N60M2 (PFC), 50R380P 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.
