General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE32J5205AK 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.
In such cases, the A6619_FSM power supply is usually faulty.
The owner of a TV can purchase an external power supply unit such as A6619_FSM and repairing it is not always advisable. In any case, the simplest typical defects characteristic of most IIP schemes can be easily detected and eliminated after opening. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary to check the power switches and rectifier diodes for a possible partial or complete breakdown.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the elements of the primary circuit, the mains fuse usually breaks.
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 circuits are usually checked by replacement with new ones, or known to be working.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
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.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, you can sometimes detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The indicator blinks or glows constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the BN41-02360B 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 cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its K4B2G1646Q, TAS5747 chips and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before changing the tuner BN40-00316A, if it is not possible to tune to television channels, you should make sure that there are supply voltages that must be measured at the corresponding terminals of the tuner and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
We recommend the owners of the UE32J5205AK 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!

Main features of the SAMSUNG UE32J5205AK device:
Installed matrix (LED-panel) CY-JJ032BGLV6V or JJ032BGE-R3.
The matrix control uses the Timing Controller (T-CON) N41-02292A.
To power the backlight LEDs, a converter is used, combined with the main board BN41-02360B.
An external source of the type A6619_FSM BN44-00837A Adapter 19.5V 3.474A is used to power all internal nodes of the SAMSUNG UE32J5205AK TV.
MainBoard - the main board (motherboard) is a BN41-02360B module, using K4B2G1646Q, TAS5747 and others.
The tuner BN40-00316A provides the reception of television programs and tuning to channels.
