General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular SAMSUNG UE40C6510UW, it is advisable to start with a careful external examination of internal and external elements. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
In the absence of any signs of operability, when the SAMSUNG UE40C6510UW 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 BN44-00357A power module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
Power switches in switching power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one.
In cases where the SAMSUNG UE40C6510UW TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the T400FBE2-DB DD01 SAMS panel). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as the contact connections in the connectors and soldering.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
In the event of a malfunction on the BN94-04235D SERK motherboard, first of all, check the operability of all stabilizers or power converters of the microcircuits and, if necessary, update the software (software).
If the TV works normally from external devices, but does not tune into television channels, the tuner BN40-00172A DTOS40CVH081A may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals, as well as the power supply of varicaps (30-33V).
Remember! Attempts to self-repair by users of the SAMSUNG UE40C6510UW TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the BN44-00357A module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the SEM3040 PWM controller. The reactance of an electrolytic capacitor of a line filter at a frequency of 50-60 Hz is usually not more than 20-30 ohms and its charge directly from the network through open diodes could reach tens of amperes per pulse if no filtering were applied.
As a result of the PFC conversion, an increased voltage on the capacitor (about 380V) cannot directly open the rectifier diodes, on the anode of which the voltage will always be slightly less (about 300V) and then its charging current will always be limited by the elements of the PWM controller. As a result, the envelope of the high-frequency pulses of the consumed current will repeat the shape and phase of the input sinusoidal voltage. The presence of an increased voltage (+ 380V) on the mains capacitor indicates the serviceability of the PFC node.
Main features of the SAMSUNG UE40C6510UW device:
Installed matrix (LED-panel) T400FBE2-DB.
The matrix control uses the Timing Controller (T-CON) V460H1-CH7.
To power the backlight LEDs, the BN44-00357A LED driver is used, controlled by the HV9963 PWM controller. As power elements of the LED driver, keys of the type SDT03N04 are used.
The necessary supply voltages for all nodes of the SAMSUNG UE40C6510UW TV are generated by the BN44-00357A power supply module or its analogs using SEM3040 (PFC), ICE3BR1765J (Standby), UCC25600 (8-Pin Resonant) microcircuits and power switches of the SD10N60 (PFC) type, TK8A50 .
