General repair guidelines for TV LCD LED
Malfunctions of the power module BN44-00353A - PD46AF0E_ZSM - PSLF121B01A-B can be expressed in different ways, for example, SAMSUNG UE40C5100 does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. After checking the mains fuse and power elements of the primary power supply circuit, you should also check for the presence of a short circuit in the loads of the secondary rectifiers.
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.
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 high probability of a malfunction of the display backlight LEDs or the LED driver (power converter of the LTF400HM02 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.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN-junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
The motherboard BN41-01549C - BN94-04496Y must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary.
If the TV works normally from external devices, but does not tune into television channels, the tuner BN40-00196A (DTOS40FVH082A) may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
Remember! Attempts to self-repair by users of the SAMSUNG UE40C5100 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

PSU Advanced
The power module BN44-00353A is made using a Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced by the device into the mains. The PFC node is a Step-Up Converter based on the SEM3040 PWM controller, which evenly distributes high-frequency impulses 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 operation mode on the capacitor of the line filter indicates the serviceability of the PFC node.
The appearance of the power supply
Main features of the SAMSUNG UE40C5100 device:
Installed matrix (LED-panel) LTF400HM02.
The matrix control uses the Timing Controller (T-CON) F60MB4C2LV0.6.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by a HV9963, KIA358F PWM controller. As power elements of the LED driver, keys of the FDPF5N50 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE40C5100 television are generated by the BN44-00353A power supply module or its analogs using UCC25600, SEM3040 (PFC), ICE3BR1765J (Standby) microchips and power switches of the TK8A50, SD10N60 (PFC) type.
MainBoard - the main board (motherboard) is a BN41-01549C module, using EEPROM chips: 24C256; SOUND: NTP7300S; K4T1G164QF-BCF; WT61P802 and others.
The tuner BN40-00196A (DTOS40FVH082A) provides the reception of television programs and tuning to channels.
