General repair guidelines for TV LCD LED
If the UE46ES6547U 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 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 TK8A50D 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 key breakdown 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 strapping of the UCC25600 PWM controller chip are subject to verification; PFC: SPC7011F (FA5695N); Standby: SQD2011K (STR2A151D), which is desirable to verify by replacement.
If the image appears and immediately disappears when the TV is turned on, or it is initially absent when it is turned on, but the sound has other functions, there is a greater likelihood of a malfunction of the display backlight LEDs or the LED driver (power converter for the LTJ460HW06-L panel backlight assembly).
Often there is a need for disassembling the panel to check the health of the LEDs, as well as the contact connections in the connectors and soldering.
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.
On the BN41-01807A BN94-05898F motherboard, in case of a malfunction, you should first check the operation of all the stabilizers and power converters of the microcircuits, and also, if necessary, update the software (software).
Before replacing the tuner BN40-00236A DNSD243VH144A, 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
It should be remembered! Attempts to repair the SAMSUNG UE46ES6547U 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!

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the BN44-00520C module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the PWM controller SPC7011F = FA5695N. The reactance of an electrolytic capacitor of a 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 mains capacitor indicates the serviceability of the PFC node.
The appearance of the power supply
Main features of the SAMSUNG UE46ES6547U device:
Installed matrix (LED-panel) LTJ460HW06-L.
The matrix control uses the Timing Controller (T-CON) LSJ460HW05-S.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SLC5012M PWM controller (MAP3312B). As the power elements of the LED driver, keys of the type KF9N25D (250V / 7.5A) are used.
The necessary supply voltages for all nodes of the SAMSUNG UE46ES6547U TV are generated by the BN44-00520C power supply module or its analogs using UCC25600, SPC7011F (PFC = FA5695N), SQD2011K (Standby = STR2A151D) microcircuits and TK8A50D power switches.
