General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE32M5000 TV does not turn on, does not respond to the remote control and control panel buttons, indicators do not light up and do not blink.
With such manifestations, in some cases, the Adapter power module is 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 necessary to measure its secondary output voltages, and if they are absent, check the power switches and rectifier diodes in the converters for a short circuit.
In case of any breakdown 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, 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, 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.
The most likely in these cases is a malfunction of the LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as a health indicator. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, the indicator signals standby or working mode, or blinks.
Repair or diagnostics of the BN41-02582B motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, you should update or replace the software (software). When repairing an MB board, you must check its CPU components: SENK20-MS. 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.
If a tuner BN37-00013A is suspected of malfunction, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary voltage levels and impulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
TV users and owners must remember that attempts to self-repair a SAMSUNG UE32M5000 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

Main features of the SAMSUNG UE32M5000 device:
Installed matrix (LED panel) CY-JM032BGER2V.
The matrix control uses the Timing Controller (T-CON) HV320FHB-N10.
To power the backlight LEDs, a converter is used, combined with the main board BN41-02582B, controlled by the BD9413F PWM controller.
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 UE32M5000 TV.
MainBoard - the main board (motherboard) is a BN41-02582B module using CPU chips: SENK20-MS, NAND ESTM NT17L 2M and others.
The tuner BN37-00013A provides the reception of television programs and tuning to channels.
