General recommendations for LCD LED TV repair
Possible defects
- SAMSUNG UE50J5500AU TV does not turn on at all. Control lights do not light or blink. TV on the remote control and the control panel buttons do not respond.
With this kind of manifestation the fault is most likely in the power supply module BN44-00704E. Then you should measure its output voltages and in case of their full or partial absence you need to check the serviceability of the power switches (TO-220, TO252) and the inverter rectifier diodes for possible short circuit.
If there is a breakdown in the secondary circuits of the inverter, it can usually fail in the short-circuit mode, and if there is a short circuit in the power elements of the primary circuit, the mains fuse or the current sensor in the source of the key most often breaks down.
Mos-Fet power switches used in switching power supplies sometimes fail due to the failure of some other element that can take it out of key mode, or cause the switch to exceed its maximum allowable parameters. These can be the elements that feed the PWM controller, the frequency or damping circuits, or the negative feedback elements in the stabilization circuit. PFC, PWM FA6A01 PWM controllers, if there is no visible damage or obvious short circuit between the pins are checked by replacing with the new ones or known good ones.
- No picture, sound is present, the remote control responds, the channels are switched. In some cases the picture appears when you switch on and immediately disappears.
Usually in such cases the fault is detected in the nodes of LED panel backlighting. Often the cause of failure is the lack of current in the circuit of LEDs, such as their breakage or short circuit, or violation of contact connections of connectors 2014SVS50_3228 slats.
It should be remembered that it is not possible to determine the breakage in the LED lines without disassembling the panel, using a tester or multimeter without an additional device, such as a current source. To open all the PN-junctions connected in series at once a voltage of several tens of volts may be required. Then you have to open the panel and check each LED separately with a multimeter. If the capabilities of your multimeter do not allow to open the LED in the forward direction or twin LEd's are used, then the PN junction of the faulty stabilizer can indirectly serve as an indication of serviceability. If the LED is faulty, the PN junction of the stabilizer will either be open or shorted.
If the SAMSUNG UE50J5500AU has no picture but has sound, often the CY-GJ050BGNV1V display backlight simply does not work. Moreover, in LED TVs usually fail LEDs inside the panel, less often the LED-driver.
In such cases you can see faintly visible image when external light hits the screen.
To replace the LEDs requires disassembly of the LCD panel CY-GJ050BGNV1V - a process which requires a master of experience and expertise. We do not recommend to perform such works by yourself to owners of TV sets and craftsmen who have no experience in LCD panel repair.
READ HOW TO REPAIR THE TV LED BACKLIGHT --------------> HERE.
If there is no image, but backlighting works - the screen becomes slightly lighter when the TV is switched on, and in the open TV you can see the light through the holes in the body of the panel.
In this case the panel may be defective - damage to the strips, cables, for example, as a consequence of moisture after an unsuccessful washing of the screen, the T-CON board (Timing Controller) may be defective. But quite often the MainBoard BN41-02353B is defective and so is the software.
Then first it is necessary to check the panel power supply voltage, fuses on the T-CON board, as well as the supply and reference voltages of the column and line drivers - VGH, VGL, Vcom.
If these measurements are within normal limits, it is necessary to trace by oscilloscope the LVDS signals from MainBoard BN41-02353B, as well as synchronizing signals to driver stubs.
Filled or unsuccessfully washed LED TV screens can be restored in about half of the cases, usually, if there is no significant damage in the cables and panel bars.

- The TV set does not turn on, the remote control does not respond. LED blinks or indicates standby mode.
Repair or diagnostic of the motherboard BN41-02353B should begin with checking the stabilizers and power converters necessary to power the microchips and matrix. If necessary, the software (software) should be updated or replaced. Often the MB board (SSB) needs to be replaced if it has complex faults, which are difficult to detect. If you're trying to repair it, check its elements - CPU: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and replace faulty chips with new ones. Some failures may be associated with the use of modern Main Board BGA soldering technology. Usually such defects are detected by local heating of the chip.
Before replacing the tuner BN40-00318B, if there is no tuning to the channels, you must first check the software and the power supply voltages on its pins. Also make sure that the tuner and the processor can exchange data via the I2C bus
Remember! Attempts to repair TV SAMSUNG UE50J5500AU by yourself, in the absence of the necessary skills and experience, strongly not recommended and are fraught with negative consequences, up to the complete unrepairable device!

Driver current limitation. BN44-00704E. General information.
To reduce the backlight current in televisions with the BN44-00704E power supply you can use the standard trimmer resistor to change the adjustment range. To do this you must lower the resistance of the resistor R9007 in series with the trimmer, for example by soldering another 10-15kOhm resistor in parallel from above.
