SAMSUNG LED  
Model:  UE22H5000 UE22H5000AK

Panel:  M215HTN01.1 // HT215F01-100

LED driver (backlight):  with integrated PSU

PWM LED driver:  BD93941FP

Power Supply (PSU):  BN44-00692A

MainBoard:  BN41-02105A (BN94-07144K)

IC MainBoard:  CPU: NT14L, SPI Flash: 25Q40, NAND: F59L1G81A

The Indicators on the front panel do not shine or blink, the TV on the remote and the control buttons do not respond. The The SAMSUNG UE22H5000 does not turn on.  There are no signs of working capacity  .

In some of these cases, the main switching power supply is faulty - module BN44-00692A.  It is necessary to measure its secondary output voltages, and in case of their absence, check the power switches and rectifier diodes in the converters for a short circuit .
the in Case of the any breakdowns in The Secondary Circuits, The Converter CAN Operate in Emergency Short Circuit MODE, and in Case of Short Circuit in The Power Elements of The Primary Circuit, The MAINS FUSE or The Current Sensor in The Source of The Key IS Often cut off.
Mos-Fet power switches used in switching power supplies sometimes fail because of the malfunction of any other elements capable of removing it from work in the key mode, or to create an excess of the maximum permissible key parameters. These may be elements feeding the PWM regulator, frequency-setting or damping circuits, or elements of negative feedback in the stabilization circuit.  PWM controllers SSC1S311, in the absence of visible damage or open fault between the terminals, are checked by replacement with new ones Or known to be in good order.

- There is no picture, there is sound, it responds to the remote.  Either the image may appear for a second when turned on and immediately disappears.

In some of these cases, the malfunction is caused by the lack of display backlighting.  The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in breaking the contact connections of the LED Bars.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panel using a tester or multimeter without an additional device, for example, a current source.  To open all PN transitions 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 individually with a multimeter. If the capabilities of your multimeter do not allow you to open the LED in the forward direction or apply dual LEd-s, then an indication of serviceability may indirectly be the PN-transition of the emergency stabilitron.  In the case of LED-a failure , the Zener diode junction will either be torn or broken in the R / 3.

- The TV does not turn on, the indicator indicates a standby or operating mode, or blinks.

The BN41-02105A or Diagnostics of Repair Motherboard Should the begin with A The Check of stabilizers needed to Power and Power Converters and The Matrix Microcircuit.  The If Necessary, Should you or Replace The Software Update (Software).  Board Repair and Replacement the CPU Chip: NT14L , SPI Flash: 25Q40, NAND: F59L1G81A are manufactured with the necessary equipment, and the corresponding element base.  Malfunctions associated with the application of BGA processor soldering techniques can be localized by warm-up.

The BN40-00281A tuner malfunction is established after checking the software and all supply voltages on its outputs.  Data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.

Attention!  Users and owners of TVs UE22H5000, who do not have the proper qualifications, knowledge and experience, very discourage attempts at self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

The matrix (LED panel) M215HTN01.1 or HT215F01-100 is installed.  
To power the backlight LEDs, a converter is used, combined with the power supply, is controlled by the PWM controller BD93941FP.  
The necessary supply voltages for all TV sets of The SAMSUNG UE22H5000 are formed by the power module BN44-00692A or its analogs using the SSC1S311 chips.  
MainBoard - mainboard (motherboard) is a module BN41-02105A, using CPU chips: NT14L, SPI Flash: 25Q40, NAND: F59L1G81A and others.  
Tuner BN40-00281A provides reception of television programs and tuning to channels.
