General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE32N5300AU TV does not turn on at all. The control lights do not light or flash. The TV on the remote control and the control panel buttons do not respond.
With such manifestations, a malfunction is most likely to be detected in the Adapter power module.
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. 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 any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often 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), in the absence of external damage and a short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
In some of these cases, a malfunction is caused by a lack of 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.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series, you may need a voltage of several tens of volts. Then it is necessary to open the panel and check each LED separately with a multimeter. If the capabilities of your multimeter do not allow you to open the LED in the forward direction or dual LEd are used, then the PN junction of the emergency zener diode can indirectly serve as a health indicator. In case of LED-a malfunction, the zener diode PN junction will either be cut off or broken into short-circuit.
- 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 BN41-02663A 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).
If you suspect a malfunction of the tuner BN40-00331B, first of all, you need 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.
Attention to users! Self-repair of a SAMSUNG UE32N5300AU TV without the appropriate qualifications and necessary experience can lead to its complete non-repairability!

Main features of the SAMSUNG UE32N5300AU device:
Installed matrix (LED panel) CY-JN032BGER1V.
The matrix control uses the Timing Controller (T-CON) 47-6021043.
To power the backlight LEDs, a converter is used, combined with the main board BN41-02663A.
To power all internal nodes of the SAMSUNG UE32N5300AU TV, an external adapter 19V type source is used.
MainBoard - the main board (motherboard) is a BN41-02663A module, using SPI Flash chips: 25Q40, EEPROM: 24C512 and others.
The tuner BN40-00331B provides the reception of television programs and tuning to channels.
