General repair guidelines for TV LCD LED
Repair of the SAMSUNG UE40ES6307U TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. Electrolytic capacitors of filters with a swollen body, as well as ring cracks or a layer of coal on burned-out resistors formed in soldered terminals of heating elements, sometimes tell the repairman the causes of the malfunction and possible consequences.
In the case when the UE40ES6307U does not turn on, does not respond to the remote control and the front panel buttons, does not blink bulbs and does not show any signs of operability, probably in this case the power module BN44-00518B - PD46B1D_CHS is faulty. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. 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 converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
If the power keys of the pulse converter are not equal, you should pay attention to other elements in their bundling, which may be the result or cause of their breakdown.
In cases where the SAMSUNG UE40ES6307U TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the LTJ400HV05-L panel). When you turn on the TV, the image may appear briefly and disappear. It must be borne in mind that with such manifestations the LEDs themselves also fail.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the LED will light up slightly.
Repair or diagnostics of the BN41-01812A BN94-05857T motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update the software (software).
In cases of complex repairs of MB (SSB) and with the necessary skills and equipment, sometimes it may be necessary to replace its CPU chips: SEMS27; NAND FLASH KLM2G1HE3F-B001; EEPROM: 24C256; SDRAM K4B2G1646C-HCK0 and other possible malfunctioning components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before replacing the tuner BN40-00239B, if there is no tuning to the channels, you must first check the software and supply voltage at its terminals.
Attention! For users and owners of UE40ES6307U TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-serviceability of the device.

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the BN44-00518B module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the SPC7011F PWM controller. 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.
