General repair guidelines for TV LCD LED
Sometimes the SAMSUNG UE32EH5047K TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the common power module BN44-00493B (PD32AVF_CHS Rev1.3). If it is working properly, you must check the standby batteries on the Main Board. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is checked by replacing it with a known good one.
If the SAMSUNG UE32EH5047K does not have an image, but there is sound, there may be a malfunction of the backlight LEDs of the DE320BGA-B1 panel 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 detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
If the motherboard BN41-01795A BN94-05951W 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.
In cases of attempts to repair the MB (SSB) board, it is necessary to check the serviceability of its elements - SOUND: NTP-7412S which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
If there is no reception of television channels, but the TV is working properly from external devices, first of all, check the voltage of the tuner BN40-00231A and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
Attention to the owners! Attempts to repair the TV SAMSUNG UE32EH5047K on its own are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE32EH5047K device:
The matrix (LED panel) DE320BGA-B1 is installed.
The matrix control uses the Timing Controller (T-CON) 32T26-C00.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the PLC controller SLC1012C (FAN7340). As power elements of the LED driver, keys of the MDD3752 type are used.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE32EH5047K TV is carried out by the BN44-00493B power module or its analogs using 2S110 microcircuits and power switches of the MDF11N65B type.
MainBoard - the main board (motherboard) is a BN41-01795A module, using microchips WT61P805, 25Q40BVSIP, NTP-7412S and others.
The tuner BN40-00231A provides the reception of television programs and tuning to channels.
