General repair guidelines for TV LCD LED
If the UE32H6410AU 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 supply module. In some cases, there may be a malfunction only in standby power. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is checked by replacing it with a known good one.
If the SAMSUNG UE32H6410AU TV does not have an image, but there is sound, a malfunction in the backlight circuits of the LED panel CY-GH032CSLV4V is likely.
In case of breaks in the LED circuit, a complete disassembly of the panel is required, the LEDs are checked for breakage, as well as the reliability of the connections in the connectors and the rations of the terminals.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using 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. Usually, 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.
If the motherboard BN41-02156A - BN94-07548E is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, and also, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - CPU: SEMS31; SPI Flash: 25Q40CL; EEPROM: S24C512; SOUND: NTP7414 to new or obviously working. In cases where BGA technologies are used, defects are usually localized by the heating method.
If there is no reception of television channels, but the TV is working properly from external devices, first of all, check the voltage of the tuner BN40-00288A and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
We recommend the owners of the UE32H6410AU TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE32H6410AU device:
Installed matrix (LED panel) CY-GH032CSLV4V.
The matrix control uses the Timing Controller (T-CON) BN95-01307A.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by a PIC16F753, 7014X * 3 PWM controller. As power elements of the LED driver, keys of the type MDD7N25, FDD6N25 * 2 are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32H6410AU TV are generated by the BN44-00707A power supply module or its analogs using microcircuits SPC7011F (PFC), FA6A01 (PWM SOP-16) and power switches of the type 10N60M2 (PFC), KF7N50 * 2.
MainBoard - the main board (motherboard) is a BN41-02156A module, using CPU chips: SEMS31; SPI Flash: 25Q40CL; EEPROM: S24C512; SOUND: NTP7414 and others.
The tuner BN40-00288A provides the reception of television programs and tuning to channels.
