General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE32H4510 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
With such manifestations, in some cases, the BN44-00696A power module is faulty. Then we recommend that you measure its output voltages and, if they are absent, you should check the health of the power switches and rectifier diodes of the converters for possible short-circuit.
In the event of breakdowns in the secondary circuits of the converter, it can usually fail in short circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most often breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) S3330 (FAN6755), in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- 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.
As a rule, in such cases there is no display backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
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.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights up constantly or blinks.
Repair or diagnostics of the BN41-02156A 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). In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - CPU: SEMS31; SPI Flash: 25Q40CL; EEPROM: S24C512; SOUND: NTP7414 to new or obviously working. In cases where BGA technologies are used, defects are usually localized by the heating method.
Before replacing the tuner BN40-00288A, 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 UE32H4510 TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

The appearance of the power supply
Main features of the SAMSUNG UE32H4510 device:
The matrix (LED panel) HH032AGH-R3 BN96-31086F is installed.
The matrix control uses the Timing Controller (T-CON) CSOT.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE32H4510 TV is carried out by the BN44-00696A power module, or its analogs using S3330 chips (FAN6755).
MainBoard - the main board (motherboard) is a BN41-02156A module, using CPU chips: SEMS31; SPI Flash: 25Q40CL; EEPROM: S24C512; SOUND: NTP7414 and others.
The tuner BN40-00288A provides the reception of television programs and tuning to channels.
