General repair guidelines for TV LCD LED
If the SAMSUNG UE39F5500 does not turn on, no control lights on the front panel light up and do not blink, therefore, there is a very high probability of a malfunction of the BN44-00645A L42S1_DSM power module. In some cases, only the processor power regulator may be faulty. 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 STD14NM50N, STF13NM60 (PFC), which are often detected in such a breakdown state.
Power switches in switching power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip SEM3110A, SQD2011K (Standby), SEM3050 (PFC), which can only be checked by replacing with a new or obviously working one.
If there is no image when you turn on the SAMSUNG UE39F5500, or it appears and immediately disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the HF390BGM-C1 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.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Usually, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). 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.
Repair or diagnostics of the motherboard BN41-01958A // BN41-01958B should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update the software (software).
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - CPU: SEMS30, SPI FLASH: W25Q40, SDRAM: K4B2G1646E. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltages at the terminals of the tuner BN40-00262A. It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.
Remember! Attempts to self-repair by users of the SAMSUNG UE39F5500 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE39F5500 device:
Installed matrix (LED-panel) HF390BGM-C1 or CY-HF390BGMV1V.
The matrix control uses the Timing Controller (T-CON) V390HJ4-CE1.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the MAP3312B PWM controller. As power elements of the LED driver, keys of the type AOD9N40, AOD5N40 are used.
The necessary supply voltages for all nodes of the SAMSUNG UE39F5500 TV are generated by the BN44-00645A power module or its analogs using SEM3110A, SQD2011K (Standby), SEM3050 (PFC) microcircuits and power switches of the STD14NM50N, STF13NM60 (PFC) type.
MainBoard - the main board (motherboard) is a BN41-01958A module, using CPU chips: SEMS30, SPI FLASH: W25Q40, SDRAM: K4B2G1646E and others.
The tuner BN40-00262A provides the reception of television programs and tuning to channels.
