General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE46ES6100W 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.
With such manifestations, in most cases, the BN44-00518B power module is faulty. It is necessary to measure the output voltages in the secondary circuits, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a possible breakdown (short circuit).
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.
Mos-Fet power switches used in switching power supplies sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode or create an excess of the maximum permissible key parameters. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers FA5760N, SPC7011F, in the absence of visible damage or frank short-circuit between the terminals, are checked by replacing with new, or obviously 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.
Usually in such cases, a malfunction is detected in the backlight nodes 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 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, the indicator signals standby or working mode, or blinks.
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, 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: SEMS27; SDRAM: K4B2G1646C-HCK0; NAND FLASH: KLM2G1HE3F-B001; EEPROM: 24C256 and other possible defective components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
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 DTDO40FSVL084AA BN40-00232A and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
Owners and users of the SAMSUNG UE46ES6100W TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The appearance of the power supply
Main features of the SAMSUNG UE46ES6100W device:
Installed matrix (LED-panel) LTJ460HW05-L.
The matrix control uses the Timing Controller (T-CON) LSJ460HW05-S.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the PWM controller SLC5012M = MAP3312B.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE46ES6100W TV is carried out by the BN44-00518B power module, or its analogs using FA5760N, SPC7011F microcircuits.
