General repair guidelines for TV LCD LED
In the absence of any signs of operability, when the SAMSUNG UE32D6530WS 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 power module BN44-00458B PD46A1D_BHS of the TV. 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 SAMSUNG UE32D6530WS does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the backlight circuits of the LD320CSC-C1 panel is likely. LEDs or their power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the backlight unit.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
To open all the junctions, several tens of volts or more are necessary, and it is best to use a current source for such purposes. An open in the LED lines connected in series cannot be detected with a multimeter or tester without disassembling the panel. In the open panel, it is necessary to check each LED. If your multimeter cannot open the LED transitions in forward bias, then see the presence of the PN transition of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
In cases of attempts to repair the motherboard BN41-01587B BN94-06108L, it is necessary to check the operability of the linear stabilizers and power converters of its microcircuits and, if possible, update the software (software). BGA chips can sometimes be diagnosed by local heating.
Before replacing the DNSS243VH142A BN40-00217A tuner, if there is no tuning for the channels, 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
Attention to the owners! Attempts to repair the TV SAMSUNG UE32D6530WS on its own are not recommended by the manufacturer and can lead to serious negative consequences!

PSU Advanced
The UE32D6530WS model uses a BN44-00458B power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a boost converter based on the PWM controller SPC7011F = FA5695N, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.
The appearance of the power supply
Main features of the SAMSUNG UE32D6530WS device:
Installed matrix (LED panel) LD320CSC-C1.
The matrix control uses the Timing Controller (T-CON) V460HK1-C01.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SLC3011M PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE32D6530WS TV are generated by the BN44-00458B power supply module or its analogs using the STR-A6052M, SPC7011F (PFC = FA5695N), FSFR1800XSL microchips and MDS1653RH type power switches.
MainBoard - the main board (motherboard) is a BN41-01587B module, using microchips SDP1001, SDP1005 and others.
The tuner DNSS243VH142A BN40-00217A provides the reception of television programs and tuning to channels.
