General repair guidelines for TV LCD LED
Possible malfunctions
- The SAMSUNG UE32K5100 TV does not turn on and does not show signs of operability at all. There is no reaction to the remote control and the control buttons from the front panel.
In some of these cases, a malfunction is detected in the power source.
The external adapter 19V power supply is not always subject to repair, especially since the owner can purchase it independently. But, in some cases, it makes sense to open it and eliminate the simple typical defects inherent in converters in pulsed sources. It is necessary to measure its output voltages and, if they are absent, to check the serviceability of power switches and rectifier diodes in the converters for possible breakdown.
In case of breakdowns of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And during short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, elements supplying a PWM controller, frequency-setting, damper, and also elements of the Negative Stabilization Feedback. PWM circuits are usually checked by replacement with new ones, or those that are known to be working.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
As a rule, in such cases there is no display backlight. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
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 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 BN41-02527A 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).
Owners and users of the SAMSUNG UE32K5100 TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
The appearance of the MainBoard BN41-02527A is shown in the figure below:BN41-02527A
Main features of the SAMSUNG UE32K5100 device:
Installed matrix (LED-panel) 1080p Full HD.
To power the backlight LEDs, a converter is used, combined with the main board BN41-02527A, controlled by the BD9413F PWM controller. As power elements of the LED driver, keys of the AO6405 type are used.
To power all internal components of the SAMSUNG UE32K5100 TV, an external adapter 19V type source is used using PWM chips.
MainBoard - the main board (motherboard) is a BN41-02527A module, using CPU chips: SENK 17, EEPROM: 24C256, NAND Flash: F59L1G81MA-25TI, SPI Flash: 25Q40CLSIP and others.
The tuner BN40-00323B provides the reception of television programs and tuning to channels.
