General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE32J5000AK 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.
In such cases, the adapter power supply is usually faulty.
The external adapter 19V 3.17A - BN44-00838A A5919_FSM 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 then necessary to measure its output voltages and, if they are absent, you should check the power switches and rectifier diodes of the converters for the probability of a 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.
The breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback (OOS) stabilization circuits. PWM controllers (PWM), if they do not have visible damage to the chassis and open short circuit between the terminals, are usually checked by replacement.
- 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.
In some of these cases, a malfunction is caused by a lack of display backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
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.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-02358A motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, you should update or replace the software (software). When repairing an MB board, you must check its components NAND: F59L1G81A-25TI, DDR: K4B2G1646Q-BCK0, FLASH: W25Q40CLSIP, EPRROM: S24C256. Defective items should be replaced. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
Malfunction of the tuner BN40-00316A DNTS403H5A is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
Attention TV owners! Attempts to self-repair SAMSUNG UE32J5000AK are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the SAMSUNG UE32J5000AK device:
Installed matrix (LED panel) CY-JJ032BGLV1V.
The matrix control uses the Timing Controller (T-CON) BN41-02111A.
To power the backlight LEDs, a converter is used, combined with a power supply.
An external source of the type A5919_FSM Adapter 19V 3.17A - BN44-00838A A5919_FSM is used to power all internal nodes of the SAMSUNG UE32J5000AK TV.
MainBoard - the main board (motherboard) is a BN41-02358A module, using NAND chips: F59L1G81A-25TI, DDR: K4B2G1646Q-BCK0, FLASH: W25Q40CLSIP, EPRROM: S24C256 and others.
The tuner BN40-00316A DNTS403H5A provides the reception of television programs and tuning to channels.
