General repair guidelines for TV LCD LED
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when it is turned on, there is a certain chance that the BN44-00754A PSLF870G06A L40G0B_ESM power module is faulty and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of standby power. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors 60R580P, which are often found in such a state of breakdown in such situations.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a key breakdown can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller microcircuit S3330 = FAN6755, which it is desirable to check by replacement, are subject to verification.
If the SAMSUNG UE40H5300AK 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 CY-HH040BGNV1V 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.
To check the health of the LEDs, as well as contact connections in the ruler circuit, the panel must be disassembled.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). 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.
Repair or diagnostics of the motherboard BN41-02217B - BN94-071558 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 chips SENK14 25Q40CLSIP S24C256C F59L1G81A K4B2G164GQ-BCKO 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 BN40-00287A, if there is no tuning to the channels, you must 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
Once again, remind users! Attempts to self-repair a SAMSUNG UE40H5300AK TV without the appropriate qualifications and experience can lead to its complete non-repairability!

Main features of the SAMSUNG UE40H5300AK device:
Installed matrix (LED panel) CY-HH040BGNV1V.
The matrix control uses the Timing Controller (T-CON) V390HJ1-XRME1.
To power the backlight LEDs, a converter is used, combined with a power supply. As power elements of the LED driver, keys of the MDD5N40 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE40H5300AK TV are generated by the BN44-00754A power module or its analogs using S3330 microcircuits (FAN6755) and power switches of the 60R580P type.
MainBoard - the main board (motherboard) is a BN41-02217B module, using SENK14 25Q40CLSIP S24C256C F59L1G81A K4B2G164GQ-BCKO chips and others.
The tuner BN40-00287A provides the reception of television programs and tuning to channels.
