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
Possible malfunctions
- The SAMSUNG UE32ES6307 TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
Usually, with such manifestations, the defect is caused by faulty elements in the main power module BN44-00517A. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches (10NM60N) and rectifier diodes in the converters for possible breakdown.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more 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 parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. 2S110 PWM controllers, in the absence of visible damage or explicit short-circuit between the terminals, are checked by replacing with new ones, 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.
Failure in most such cases is detected in the nodes and backlight elements of the LED panel. 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 strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, you can sometimes detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
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). If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - CPU: SEMS27, WT61P805, NAND FLASH KLM2G1HE3F-B001, EEPROM: 24C256, SDRAM K4B2G1646C-HCK0, MTP-7412S, TPS54427. Defective components should be replaced.
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
Attention TV owners! Attempts to self-repair SAMSUNG UE32ES6307 are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the SAMSUNG UE32ES6307 device:
Installed matrix (LED-panel) LE320CSM-C1.
The matrix control uses the Timing Controller (T-CON) V400HK5-CPS1.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SLC5012M PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE32ES6307 TV are generated by the BN44-00517A power module or its analogs using 2S110 microcircuits and 10NM60N power switches.
MainBoard - the main board (motherboard) is a BN41-01812A module, using CPU chips: SEMS27, WT61P805, NAND FLASH KLM2G1HE3F-B001, EEPROM: 24C256, SDRAM K4B2G1646C-HCK0, MTP-7412S, other TPS54427 and others.
