General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE22ES5000W does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
Sometimes, in such cases, the BN44-00505B power module is faulty. It is necessary to measure its output voltages, and in case of their absence, it is necessary to check the serviceability of the power switches of the converters and rectifier diodes for the probability of a short circuit.
In case of breakdowns in breakdowns of diodes 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 usually breaks.
PWM (PWM) 3BR1065JF, if there is no open fault between the terminals, it is checked by replacing with a known-good one.
- 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 most 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 open circuit 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 at once, a voltage of several tens of volts may be required. 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 blinks or glows constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the BN41-01798A 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). Board repair and replacement of CPU chips: SEMS23; DRAM: K4B1G1646G; NAND Flash: K9F1G08U0D; EEPROM: 24C256; SOUND: NTP-7412S are manufactured with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
If a tuner BN40-00231A 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 supply voltage levels and data exchange pulses with the processor via the I2C bus at the corresponding tuner pins.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair to professionals with sufficient experience in the repair of electronic equipment.

BN41-01798A can be used in TVs:
SAMSUNG UE22ES5030W (Panel M215HW03 V.1), SAMSUNG UE22ES5000W (Panel M215HW03 V.1), SAMSUNG UE19ES4000W UE19ES4000 (Panel HT185WX-300).
The appearance of the power supply
Main features of the SAMSUNG UE22ES5000W device:
Installed matrix (LED-panel) M215HW03 V.1.
The matrix control uses the Timing Controller (T-CON) M215HW03.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the MAP3204C PWM controller. As power elements of the LED driver, keys of the type 9997GH are used.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE22ES5000W TV is carried out by the BN44-00505B power module, or its analogs using 3BR1065JF microcircuits.
MainBoard - the main board (motherboard) is a BN41-01798A module, using CPU chips: SEMS23; DRAM: K4B1G1646G; NAND Flash: K9F1G08U0D; EEPROM: 24C256; SOUND: NTP-7412S and others.
The tuner BN40-00231A provides the reception of television programs and tuning to channels.
