In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!

General repair guidelines for TV LCD LED
In the case when the UE40ES6100W does not turn on, does not respond to the remote control and buttons on the front panel, does not blink bulbs and does not show any signs of operability, the BN44-00518B power supply module is probably defective in this case. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
Key breakdown in switching power supplies (PPS) usually does not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If the SAMSUNG UE40ES6100W TV does not have an image, but there is sound, a malfunction in the backlight circuits of the LTJ400HV05-L LED panel is likely.
Often there is a need to disassemble the panel to check the health of the LEDs on the strips 40NNB 3D-7032LED-MCPCB-L V2GE-400SMA-R3 (11,12,12) and 40NNB 3D-7032LED-MCPCB-R V2GE-400SMB-R3 (11,12 , 12), as well as their contact connections in the connectors.
When trying to identify a break in the LED lines, it should be borne in mind that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
Repair or diagnostics of the BN41-01812A BN94-05678T motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update the software (software).
In some cases, they require checking or replacing (if necessary) the elements of the MB board (SSB) - CPU: SEMS27; NAND FLASH KLM2G1HE3F-B001; EEPROM: 24C256; Submicom: WT61P805. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If you suspect a malfunction of the tuner BN40-00239B, first of all, you need to make sure the software is correct, as well as the presence of the necessary voltage levels at the corresponding terminals of the tuner.
For owners of the UE40ES6100W TV, we recommend that you contact qualified personnel with experience to repair! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

PSU Advanced
The power module BN44-00518B is made using the Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced into the power supply by the device. The PFC assembly is a Step-Up Converter based on the SPC7011F PWM controller, which evenly distributes high-frequency impulses of the charging current of the electrolytic capacitor of the rectifier filter of the mains voltage over a period of 50 Hz. The current of its charge in this case will already be determined not by its reactance (usually 10-30 ohms for the network frequency), but by the elements of the converter. As a result, a change in the amplitude of the pulses (envelope) of the consumed current of the converter will repeat the shape and phase of the input sinusoidal voltage. The availability of the increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.
The appearance of the power supply
Main features of the SAMSUNG UE40ES6100W device:
Installed matrix (LED-panel) LTJ400HV05-L.
The matrix control uses the Timing Controller (T-CON) LSJ400HV05-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 UE40ES6100W TV 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; Submicom: WT61P805 and others.
The tuner BN40-00239B provides the reception of television programs and tuning to channels.
