General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE40H6500 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.
Most likely in this case, the main switching power supply (MPS) BN44-00709A is faulty. 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 any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more 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), FA6A01N (FA5760N), 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, it reacts to the remote control. Or the image appears when you turn on and immediately disappears
Usually in such cases, a malfunction is detected in the backlight nodes of the LED panel. 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, you can sometimes 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 TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-02156A 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). 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 CPU chips: SEMS31; SPI Flash: 25Q40CL; EEPROM: S24C512; SOUND: NTP7414 and other possible malfunctioning components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before changing the tuner BN40-00288A, if it is not possible to tune 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
Once again, remind users! Attempts to self-repair a SAMSUNG UE40H6500 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 UE40H6500 device:
Installed matrix (LED panel) CY-GH040CSLV1V.
The matrix control uses the Timing Controller (T-CON) BN41-02110.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE40H6500 TV are generated by the power module BN44-00709A, or its analogs using S3051 (PFC), FA6A01N (FA5760N) microcircuits.
MainBoard - the main board (motherboard) is a BN41-02156A module, using CPU chips: SEMS31; SPI Flash: 25Q40CL; EEPROM: S24C512; SOUND: NTP7414 and others.
The tuner BN40-00288A provides the reception of television programs and tuning to channels.
