General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE55ES6307 TV does not turn on, does not respond to the remote control and control panel buttons, indicators do not light up and do not blink.
Most likely in this case, the main switching power supply (IIP) BN44-00518B is faulty. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches and rectifier diodes in the converters for possible breakdown.
In the event of breakdowns in the secondary circuits of the converter, it can usually fail in short circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most 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) FA5760N, SPC7011F (PFC) are usually checked by replacing with new, or obviously working.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
The most likely in these cases is a malfunction of the LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- 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 BN41-01812A 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). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: SEMS27; NAND FLASH KLM2G1HE3F-B001; EEPROM: 24C256; Submicom: WT61P805 requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
If you suspect a malfunction of the tuner BN40-00239B, first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
It should be remembered! Attempts to self-repair a SAMSUNG UE55ES6307 TV, 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!

The appearance of the power supply
Main features of the SAMSUNG UE55ES6307 device:
Installed matrix (LED panel) LTJ550HW08-L.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the SLC5012M PWM controller.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE55ES6307 TV is carried out by the BN44-00518B power module, or its analogs using the FA5760N, SPC7011F (PFC) microcircuits.
