General repair guidelines for TV LCD LED
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when it is turned on, there is a certain probability that the BN44-00475A power supply module is defective and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of standby power. 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.
A 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 there is no image when you turn on the SAMSUNG UE55D6100SW, or it appears and immediately disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the LTJ550HW04-L panel, or in the LED node of the driver - their power converter.
The lack of backlight often occurs due to an open circuit in the LED circuit. There is a need for disassembling the panel and checking the LEDs themselves, as well as the same contact connections in the connectors and rations of the terminals.
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. Typically, 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 an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
Diagnosis and repair of the motherboard BN41-01587E - BN94-04975Z usually begins with a test of the performance of the stabilizers and power converters of the module chips. In some cases, a software update is required.
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its chips SDP1001, SDP1005, SDP94, SIL9489ACTU, K4B2G1646C-HCH9, EPM240T100C4N and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before replacing the tuner BN40-00217A, 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 TV SAMSUNG UE55D6100SW without the appropriate qualifications and experience can lead to its complete failure to repair!

Main features of the SAMSUNG UE55D6100SW device:
Installed matrix (LED-panel) LTJ550HW04-L.
The matrix control uses the Timing Controller (T-CON) BN41-01744.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE55D6100SW TV is carried out by the BN44-00475A power module, or its analogues.
MainBoard - the main board (motherboard) is a module BN41-01587E, using microchips SDP1001, SDP1005, SDP94, SIL9489ACTU, K4B2G1646C-HCH9, EPM240T100C4N and others.
The tuner BN40-00217A provides the reception of television programs and tuning to channels.
