General repair guidelines for TV LCD LED
In the absence of any signs of operability, when the SAMSUNG UE22ES5030W does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the 23A0Q power supply module of the TV. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and 9967GH transistors, which are often found in such a state of breakdown in such situations.
The breakdown of the power switch of the pulse converter is often triggered by other elements, for example, in the stabilization or control circuits of this switch, as well as by the damper elements in its drain and TPI winding.
Sometimes the SAMSUNG UE22ES5030W TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a possibility of a malfunction of the LED driver - the power converter of the backlight LEDs of the M215HW03 V.1 panel, or an open circuit in the LED circuit is possible. In such cases, first of all, it is necessary to verify the operability of the electrolytic capacitors of the filter by supplying the backlight unit.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as the contact connections in the connectors and soldering.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source. By opening the panel, each LED can be checked separately. Usually, Chinese multimeters light up a single 3-volt LED, if you connect probes in the forward direction to it. 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.
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, update the software (software).
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: SEMS23; DRAM: K4B1G1646G; NAND Flash: K9F1G08U0D; EEPROM: 24C256; SOUND: NTP-7412S requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
The malfunction of the tuner BN40-00231A is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
Once again, remind users! Attempts to self-repair a SAMSUNG UE22ES5030W TV without the appropriate qualifications and experience can lead to its complete non-repairability!

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 UE22ES5030W device:
Installed matrix (LED-panel) M215HW03 V.1.
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 AP9997GH are used.
The necessary supply voltages for all nodes of the SAMSUNG UE22ES5030W TV are generated by the BN44-00505B power module or its analogs using 3BR1065JF microcircuits and 9967GH type power switches.
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.
