General repair guidelines for TV LCD LED
Possible malfunctions
- The SAMSUNG UE32J4100 TV does not turn on and does not show any signs of turning on, it does not respond to the control buttons or the remote control.
Often in such cases, the BN44-00700A power module is faulty. It is necessary to measure its output voltages and, if they are absent, to check for short-circuit probabilities in the converters, power switches (K10A60W, MBRF10150CTL) and rectifier diodes.
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.
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) 3S111, 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 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 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 BN41-02098B 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). When repairing an MB board, it is necessary to check its components F59L1G81A, 25Q40CLSIP, S24C256, K4B2G1646Q-BCKO, NTP7414. 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.
Before replacing the tuner BN40-00294A, 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 to users! Self-repair of a SAMSUNG UE32J4100 TV without the appropriate qualifications and necessary experience can lead to its complete non-repairability!

The appearance of the power supply
Main features of the SAMSUNG UE32J4100 device:
Installed matrix (LED-panel) HH032AGS-R1.
The matrix control uses the Timing Controller (T-CON) RUNTK.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the SAMSUNG UE32J4100 TV are generated by the BN44-00700A power module or its analogs using 3S111 microcircuits and power switches of the K10A60W, MBRF10150CTL type.
MainBoard - the main board (motherboard) is a BN41-02098B module, using chips F59L1G81A, 25Q40CLSIP, S24C256, K4B2G1646Q-BCKO, NTP7414 and others.
The tuner BN40-00294A provides the reception of television programs and tuning to channels.
