General repair guidelines for TV LCD LED
Possible manifestations of defects
- The SAMSUNG UE40J6590 TV does not turn on and does not show any signs of switching on, it does not respond to the control buttons or the remote control.
In some of these cases, a fault is detected in the BN44-00803A power supply module. It is necessary to measure its output voltages, and in case of their absence, check the operability of the power switches of the converters and rectifier diodes for the probability of short circuit.
In case of breakdowns of diodes in the secondary circuits, the converter can operate in emergency short circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually 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. PWM circuits are usually checked by replacement with new ones, or known to be 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.
In some of these cases, a malfunction is caused by a lack of display backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V for them. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up a single 3-volt LED, if you connect the probes in the forward direction, the red probe to the anode, and the 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.
- 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 BN41-02353B 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). 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 - CPU: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.
Before changing the tuner BN40-00318B, if there is no possibility of tuning to television channels, you should make sure that there are supply voltages that must be measured at the corresponding terminals of the tuner and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Attention! For users and owners of UE40J6590 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 UE40J6590 device:
Installed matrix (LED panel) CY-WJ040CGLV1V.
The matrix control uses the Timing Controller (T-CON) BN41-02229A.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE40J6590 TV is carried out by the power module BN44-00803A, or its analogues.
MainBoard - the main board (motherboard) is a BN41-02353B module, using CPU chips: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and others.
The tuner BN40-00318B provides the reception of television programs and tuning to channels.
