SAMSUNG UE32F5020AK
General repair guidelines for TV LCD LED
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain chance that the power module BN44-00605A - L32SF_DSM - PSLF770S05A is faulty and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of standby power. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors 10NM60N for the possibility of an avalanche or thermal breakdown.
If the power keys of the pulse converter are not equal, you should pay attention to other elements in their bundling, which may be the result or cause of their breakdown.
If the SAMSUNG UE32F5020AK does not have an image, but there is sound, there may be a malfunction of the T320HVF03.0 backlight LEDs or their power converter - LED driver.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
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.
If the BN41-01955B BN94-06292P motherboard is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, and also, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
Board repair and replacement of microchips SEMS29, 25040CLSIP, F59L1G81A-25TIG, K4B1G1646G-BCKO, S24C256C, 24C02, DRV612, NTP-7412S are carried out with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
Before changing the tuner DNTS403EH105A BN40-00262A, if it is not possible to tune to television channels, make sure that there are supply voltages that need to be measured on 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, remind users! Attempts at self-repair of a SAMSUNG UE32F5020AK TV without the appropriate qualifications and experience can lead to its complete non-repairability!
One of the typical SAMSUNG UE32F5020AK faults often occurs in the T320HVF03.0 // HF320BGA - B1 LED panel from Samsung.
External manifestations: no image, the backlight does not work. The LED driver provides maximum voltage for powering the LEDs. Usually the LEDs themselves turn out to be faulty, which, when tested, turn out to be either in a cliff or with broken internal zener diodes.
The LEDs in this case must be replaced, and the maximum driver current limited by 10-20% according to the bulletin from the manufacturer.SCHEMATIC -----------> Chassis: U85B, U85C. Models: UE**F5000A*, UE32F4800AW, UE**F5005AK, UE**F5020AK, UE**F5070SS, UE32F40**AW

Main features of the SAMSUNG UE32F5020AK device:
Installed matrix (LED-panel) T320HVF03.0 or HF320BGA - B1.
The matrix control uses the Timing Controller (T-CON) V320HVN03.0.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SEM5027A PWM controller. As power elements of the LED driver, keys of the D9N40, 3N40K type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32F5020AK TV are generated by the BN44-00605A power supply module or its analogs using S3310 microcircuits (NCP1200D60) and 10NM60N power switches.
MainBoard - the main board (motherboard) is a BN41-01955A module, using microchips SEMS29, 25040CLSIP, F59L1G81A-25TIG, K4B1G1646G-BCKO, S24C256C, 24C02, DRV612, NTP-7412S and others.
Tuner DNTS403EH105A BN40-00262A provides the reception of television programs and tuning to channels.
