General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular SAMSUNG UE32C6510UW, it is advisable to start with a careful external examination of internal and external elements. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, through ring cracks in the soldering of the outputs of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external signs of certain malfunctions.
If the TV does not turn on, no control lights are on or blinking, there are no sounds when you turn on, there is not the slightest sign of operability - the most likely malfunction is in the power module. 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.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuit.
Sometimes the SAMSUNG UE32C6510UW TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the LTF320HF02 panel backlight LED converter, or a break in the LED circuit is possible. In such cases, first of all, it is necessary to verify the operability of the electrolytic capacitors of the filter by supplying the LED driver itself, including the PSU.
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 check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN-junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
Repair or diagnostics of the BN41-01444C BN94-04168T motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update the software (software).
Before replacing the DTOS40CVH081A BN40-00172A tuner, if there is no channel setting, you must first check the software and the supply voltage at its terminals.
Attention! For users and owners of UE32C6510UW TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

BN41-01444C
BN41-01444C can be used in TVs:
SAMSUNG UE40C6510UW (Panel T400FBE2-DB), SAMSUNG UE32C6510UW (Panel LTF320HF02), SAMSUNG UE55C6000RW UE55C6000 (Panel LTF550HJ03), SAMSUNG UE40C6000 UE40C6000RW05 (Panel)
The appearance of the power supply
Main features of the SAMSUNG UE32C6510UW device:
Installed matrix (LED-panel) LTF320HF02.
The matrix control uses the Timing Controller (T-CON) S120APM4C4LV0.4.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SELC2010 PWM controller. As the power elements of the LED driver, keys of the K5A50D type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32C6510UW TV are generated by the BN44-00355A power supply module or its analogs using ICE3BR1765J (Standby), UCC25600 (PWM Resonant 8pin) microcircuits and power switches of the FQPF9N50CF type.
MainBoard - the main board (motherboard) is a BN41-01444C module, using CPU chips: SDP92, DRAM: K4T1G164QF; NAND Flash: KFG8GH6U4M-AIB6 (BGA) and others.
Tuner DTOS40CVH081A BN40-00172A provides the reception of television programs and tuning to channels.
