General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE32H4500AK does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
Often in such cases, the BN44-00696A power module is faulty. It is necessary to verify the presence of its output voltages and, if they are completely absent, check the power switches and rectifier diodes for a probable short circuit.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the main fuse and, less often, the current sensor at the source of the key are most often cut off.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM chipsets S3330 (FAN6755) are usually checked by replacing with new, or obviously working.
- There is no image, there is sound, there is a reaction to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
Often in such cases, there is no LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
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.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
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 DHTQ403IH286A, if there is no tuning for 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
We recommend the owners of the UE32H4500AK TV for repair only to qualified specialists with the necessary work experience! Attempts to repair it yourself without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE32H4500AK device:
Installed matrix (LED-panel) CY-HH032AGLV2V.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE32H4500AK TV are generated 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.
Tuner BN40-00288A DHTQ403IH286A provides the reception of television programs and tuning to channels.
