General repair guidelines for TV LCD LED
Possible malfunctions
- The SAMSUNG UE40J6300AU TV does not turn on and does not show any signs of turning on, it does not respond to the control buttons or the remote control.
Most likely in this case, the main switching power supply (IIP) BN44-00703G is faulty. It is necessary then to measure its output voltages and, if they are absent, you should check the power switches (13N60M2 (PFC), 14NM50N) and rectifier diodes of the converters for a short circuit probability.
In case of breakdowns of semiconductors in secondary circuits, the converter can usually work abnormally in short circuit mode, and during short circuit in the power elements of the primary circuit, the main fuse often breaks.
The breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback (OOS) stabilization circuits. PWM controllers (PWM) S3051 (PFC), FA6A20, if they do not have visible damage to the case and open fault between the terminals, are usually checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
In such cases, the most likely malfunction of the backlight elements of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
- The indicator blinks or glows constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the BN41-02353B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, you should update or replace the software (software). If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - CPU: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA. Defective components should be replaced.
If there is no reception of television channels, but the TV works properly from external devices, first of all, check the voltage of the tuner BN40-00318A DNTS243H5A and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
Attention to users! Self-repair of a SAMSUNG UE40J6300AU TV without the appropriate qualifications and necessary experience can lead to its complete non-repairability!

The appearance of the power supply
Main features of the SAMSUNG UE40J6300AU device:
Installed matrix (LED panel) CY-GH040CSLV8V.
The matrix control uses the Timing Controller (T-CON) BN41-02110A.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller. As power elements of the LED driver, keys of the type 5N40, KF3N40W are used.
The necessary supply voltages for all nodes of the SAMSUNG UE40J6300AU TV are generated by the BN44-00703G power supply module or its analogs using S3051 (PFC), FA6A20 microchips and 13N60M2 (PFC), 14NM50N power switches.
MainBoard - the main board (motherboard) is a BN41-02353B module, using CPU chips: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and others.
The tuner BN40-00318A DNTS243H5A provides the reception of television programs and tuning to channels.
