General repair guidelines for TV LCD LED
If the UE32F4500AK TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink, there is a high probability of a malfunction in the power module. In some cases, there may be a malfunction only in standby power. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
To power the backlight LEDs, the Led-driver is used, which is integrated with the power module and is a step-up voltage converter (Step-Up-Converter) with current stabilization in the load.
If the SAMSUNG UE32F4500AK TV does not have an image, but there is sound, there may be a malfunction in the backlight circuits of the HF320AGH-R1 LED panel.
A malfunction in the backlight circuits often occurs due to a break in the power supply lines of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the soldering of their outputs, as well as the reliability of the connections in the connectors and the soldering of the conclusions of the connectors.
It is impossible to check the line of series-connected LEDs without a special current source, and it is not safe to use any voltage sources for this purpose. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up a single 3-volt LED, if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode.
6-volt Ice with two P-N junctions is thus more difficult to verify. But if there is no short circuit or leak in both directions and the transition of the protective zener diode is caused by a multimeter, there is a high probability that this LED is working.
Repair or diagnostics of the BN41-01958 B motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update the software (software).
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 CPU chips: SEMS30, SPI FLASH: W25Q40, SDRAM: K4B2G1646E 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 BN40-00262B, if there is no tuning to the channels, first check the software and the necessary supply voltages at its terminals. Data exchange with the processor can be viewed with an oscilloscope.
Attention to the owners! Attempts to repair the TV SAMSUNG UE32F4500AK on its own are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE32F4510AK device:
The matrix (LED panel) HF320AGH-R1 is installed.
The matrix control uses the Timing Controller (T-CON) ST3151A04-5.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the BD8174MU PWM controller.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE32F4510AK TV is carried out by the BN44-00604B power module, or its analogs using 2S110 microcircuits.
MainBoard - the main board (motherboard) is a BN41-01958B module, using CPU chips: SEMS30, SPI FLASH: W25Q40, SDRAM: K4B2G1646E and others.
The tuner BN40-00262B GT2CX-3S / K3S provides the reception of television programs and tuning to channels.
