General repair guidelines for TV LCD LED
In the absence of any signs of operability, when the SAMSUNG UE32F6100 does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV's BN44-00620A power module. 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.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, PWM controller D2011K (Standby), SLC2013M (PWM resonant), S3050 (PFC), which can only be checked by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the SAMSUNG UE32F6100 has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the HF320CSA-B1 panel, or their power converter - LED driver. Sometimes, when turned on, the image appears and immediately disappears. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the backlight unit.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the circuit of the LED lines without disassembling the panels with 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 a health indicator. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
Diagnostics and repair of the BN41-01954A - BN94-06532L motherboard 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 attempts to repair the MB board (SSB), it is necessary to check the health of its elements - CPU: SENK13; EEPROM: 24C256, SPI FLASH: 25Q40 which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
Before changing the tuner BN40-00262A, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding terminals of the tuner and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Owners and users of the SAMSUNG UE32F6100 TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

PSU Advanced
The UE32F6100 TV has a BN44-00620A power module using the PFC (Power Factor Correction) scheme acting as an active filter to eliminate the higher harmonic components of the current consumption. The boost converter based on the S3050 PWM controller does not allow the electrolytic capacitor of the input rectifier filter to be connected directly to the network directly through open diodes, when the reactance (about 15-30 ohms at a frequency of 50 Hz) determines the charge current. As a result of the conversion, the charging current of the capacitor will be determined in such a way that the envelope of the high-frequency pulses of the input current will repeat the phase and shape of the sine wave of the input voltage. The health check of the PFC unit is carried out by measuring the DC voltage on the capacitor of the rectifier network. In operating mode, it should be around 380V, in standby approximately 300V.
The appearance of the power supply
Main features of the SAMSUNG UE32F6100 device:
The matrix (LED panel) HF320CSA-B1 is installed.
The matrix control uses the Timing Controller (T-CON) T320HVN03.1.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the SLC2013M * 2 PWM controller. As power elements of the LED driver, keys of the KF9N25D type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32F6100 TV are generated by the BN44-00620A power module or its analogs using S3050 (PFC), D2011K (Standby), ADP3110A microcircuits and RJK60S3 (PFC), 14NM50N * 2 power switches.
MainBoard - the main board (motherboard) is a BN41-01954A module, using CPU chips: SENK13; EEPROM: 24C256, SPI FLASH: 25Q40, SOUND: NTP-7412S and others.
The tuner BN40-00262A // BN40-00262B provides the reception of television programs and tuning to channels.
