General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE43M5513AU TV does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
Usually with such manifestations, the defect is caused by faulty elements in the main Power supply module. It is necessary to measure its output voltages and, if they are absent, to check the short circuit probability in the converters power switches and rectifier diodes.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
The breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in the circuits supplying the PWM controller, frequency-setting or damper ones, as well as in the circuits of Negative Feedback (OOS) stabilization. PWM controllers (PWM), if they do not have visible damage to the chassis and open short circuit between the terminals, are usually checked by replacement.
- 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.
As a rule, in this case, the backlight of the LED panel is faulty. The reason can be found in the failure of the LEDs, in the violation of the contact connections of the LED strips, or in the provision of their power (LED-driver).
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN-junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-02575B 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 a tuner BN40-00331B is suspected of malfunction, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary supply voltage levels and data exchange pulses with the processor via the I2C bus at the corresponding tuner pins.
It should be remembered! Attempts to self-repair a TV SAMSUNG UE43M5513AU, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

Main features of the SAMSUNG UE43M5513AU device:
Installed matrix (LED panel) CY-KK043BGAV4V.
The matrix control uses the Timing Controller (T-CON) T430HVN01.6.
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 UE43M5513AU TV is carried out by the Power supply module, or its analogues.
MainBoard - the main board (motherboard) is a BN41-02575B module, using CPU chips: SDP1604 and others.
The tuner BN40-00331B provides the reception of television programs and tuning to channels.
