General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE50F6330 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
Typically, with such manifestations, the defect is caused by faulty elements in the main power module BN44-00624A. It is necessary to measure its output supply voltage, and in case of their absence, check the operability of the power switches (K10A60W) of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of breakdowns of semiconductors in the secondary circuits, the converter can usually work abnormally in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse often breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. Chips PWM (PWM) D2011K (Standby) are usually checked by replacing with new, or obviously working.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
The most likely in these cases is a malfunction of the LED backlight. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, sometimes you can detect the presence of a PN junction 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.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the BN41-01958B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - SEMS30, WT61P807, K4B2G1646E, KLM4G1FE3B, 25Q40, 25Q40, WT61P807, TAS5745 and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
The malfunction of the tuner BN40-00262B is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
Attention! For users and owners of UE50F6330 TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

The appearance of the power supply
Main features of the SAMSUNG UE50F6330 device:
The matrix (LED panel) HF500CSA-B1 or T500HVF02.4 is installed.
The matrix control uses the Timing Controller (T-CON) T460HVN5.3.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the SAMSUNG UE50F6330 TV are generated by the BN44-00624A power module or its analogs using D2011K (Standby) microcircuits and K10A60W type power switches.
MainBoard - the main board (motherboard) is a BN41-01958B module, using chips SEMS30, WT61P807, K4B2G1646E, KLM4G1FE3B, 25Q40, 25Q40, WT61P807, TAS5745 and others.
The tuner BN40-00262B provides the reception of television programs and tuning to channels.
