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
If the SAMSUNG UE32D6100SW does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a BN44-00458A power supply module malfunctioning. In some cases, only the processor power regulator may be faulty. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors 10NM60N (PFC), which are often detected in such a state of breakdown.
Power switches in switching power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip SPC7011F = FA5695N (PFC), D2011K (Standby), FSFR1700XS (PWM), which can only be checked by replacing with a new or obviously working one.
If the SAMSUNG UE32D6100SW has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the LD320CGC-C2 panel, or their power converter - LED driver. Sometimes, when turned on, the image appears and immediately disappears. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the backlight unit.
A malfunction in the backlight circuits often occurs due to a break in the power supply lines of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the soldering of their outputs, as well as the reliability of the connections in the connectors and the soldering of the conclusions of the connectors.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
The motherboard BN41-01604C must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up continuously. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary.
If it is not possible to replace the MB (SSB) card, you must check the health of its elements - CPU: SDP1001; NAND Flash: KFG2G16Q2M; WT61P805, Sil9489ACTUC. Defective components should be replaced.
Before replacing the tuner BN40-00211A, if there is no tuning to the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Attention! For users and owners of UE32D6100SW TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

 The appearance of the MainBoard BN41-01604C is shown in the figure below:
BN41-01604C
BN41-01604C can be used in TVs:
SAMSUNG UE40D6100SW (Panel LTJ400HV03-L), SAMSUNG UE37D6100 SW (Panel LD370CGB-C2), SAMSUNG UE46D6100 UE46D6100SW (Panel LTJ460HW03-V), SAMSUNG UE32D6100SW (Panel LD306SWGC)
PSU Advanced
The BN44-00458A power module is installed in the UE32D6100SW TV using the PFC (Power Factor Correction) scheme acting as an active filter to eliminate the higher harmonic components of the current consumption. The boost converter based on the PWM controller SPC7011F = FA5695N does not allow the input rectifier filter's electrolytic capacitor to be connected directly to the network directly through open diodes when the reactance (about 15-30 ohms at a frequency of 50 Hz) determines the charge current. As a result of the conversion, the charging current of the capacitor will be determined in such a way that the envelope of the high-frequency pulses of the input current will repeat the phase and shape of the sine wave of the input voltage. The health check of the PFC unit is carried out by measuring the DC voltage on the capacitor of the rectifier network. In operating mode, it should be around 380V, in standby approximately 300V.
The appearance of the power supply
Main features of the SAMSUNG UE32D6100SW device:
Installed matrix (LED panel) LD320CGC-C2 / 1021.
The matrix control uses the Timing Controller (T-CON) BN81-06434A.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the SEM5025 PWM controller. As power elements of the LED driver, keys of the MDD5N40 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32D6100SW television are generated by the BN44-00458A power supply module or its analogs using microchips SPC7011F (FA5695N PFC), D2011K (Standby), FSFR1700XS (PWM) and power switches of the 10NM60N (PFC) type.
MainBoard - the main board (motherboard) is a BN41-01604C module, using CPU chips: SDP1001; NAND Flash: KFG2G16Q2M; WT61P805, Sil9489ACTUC and others.
The tuner BN40-00211A provides the reception of television programs and tuning to channels.
