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 cases where the SAMSUNG UE40ES5530W TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the power module BN44-00502A - PD46A1_CSM is most likely to be faulty or there is no standby power. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
In the event of a malfunction of the power switches of the pulse converter, attention should also be paid to other elements in their bundling, which may be the result or cause of their breakdown.
If SAMSUNG UE40ES5530W does not have an image, but there is sound, the backlight LEDs of the CY-LE400BGSV1L panel may be malfunctioning, LED strips LED 2012SVS40 7032NNB LEFT / RIGHT56 2D Rev1.1 120317. There may also be a malfunction in the node of their power converter - LED driver.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and 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.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - CPU: SEMS27; NAND FLASH KLM2G1HE3F-B001; EEPROM: 24C256; SDRAM K4B2G1646C-HCK0 for new or obviously working. In cases where BGA technologies are used, defects are usually localized by the heating method.
In the absence of tuning to local television channels, you should make sure that the software is correct, as well as the presence of supply voltages at the terminals of the tuner DNTS403EL144AA BN40-00239B.
It should be remembered! Attempts to repair the SAMSUNG UE40ES5530W TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

PSU Advanced
The UE40ES5530W TV is equipped with a BN44-00502A power module 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 UE40ES5530W device:
Installed matrix (LED panel) CY-LE400BGSV1L.
The matrix control uses the Timing Controller (T-CON) CPWBX.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the SAMSUNG UE40ES5530W TV are generated by the power module BN44-00502A, or its analogs using microchips SPC7011F (PFC = FA5695N), FSFR1700XSL, SQD2011K (Standby).
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 DNTS403EL144AA BN40-00239B provides the reception of television programs and tuning to channels.
