General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE46ES6200 TV does not turn on. There are no signs of operability. The indicators on the front panel do not light or flash, the TV does not respond to the remote control and control buttons.
Most often, with such manifestations, the main power module BN44-00518B is found to be 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 case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the 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) FA5760N, SPC7011F (PFC), if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- There is no image, there is sound, there is a reaction to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
In some of these cases, a malfunction is caused by a lack of display backlight. 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 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 indicator blinks or glows constantly, the TV does not turn on, 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, you should update or replace the software (software). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the CPU elements: SEMS27; NAND FLASH KLM2G1HE3F-B001; EEPROM: 24C256; SDRAM K4B2G1646C-HCK0. BGA chip malfunctions are usually easy to detect by warming up.
Before changing the tuner BN40-00239B, if it is not possible to tune to television channels, 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, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair to professionals with sufficient experience in the repair of electronic equipment.

The appearance of the power supply
Main features of the SAMSUNG UE46ES6200 device:
Installed matrix (LED-panel) LTJ460HW05-C.
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 UE46ES6200 television is carried out by the BN44-00518B power module, or its analogs using FA5760N, SPC7011F (PFC) microcircuits.
MainBoard - the main board (motherboard) is a BN41-01812A module, using CPU chips: SEMS27; NAND FLASH KLM2G1HE3F-B001; EEPROM: 24C256; SDRAM K4B2G1646C-HCK0 and others.
The tuner BN40-00239B provides the reception of television programs and tuning to channels.
