General Recommendations for Repair TV LCD LED
Possible malfunctions
- SAMSUNG UE49N5510AU does not turn on, does not respond to the remote and the control panel buttons, does not shine and does not flash indicators.
Usually with similar manifestations, the defect is caused by faulty elements in the main power module BN44-00957A. It is necessary to measure its output voltages and, if there is no absence, check the health of power keys (TO-252) and rectifiable diodes in converters for a probable breakdown.
In the breakdowns of diodes in secondary circuits, the converter can operate in the emergency short circuit mode without output voltages, and when the PRT in the power elements of the primary circuit, a network fuse and / or current sensor in the key of the key is usually broken.
Power key breakdown (MOSFET) in pulse sources is sometimes caused by the faults of other schema elements, for example, in chains that feed the PWM controller, frequency and damping, as well as in the negative feedback (EOS) stabilization circuits. PFC (SO-8), PWM (SO-16) PWM (SO-8), PWM (SO-16), if you do not have visible damage to the body and a frank KZ between outputs, are usually checked by replacement.
- No images, the sound, is, the remote control reacts. Either immediately after switching on for a second, the image may appear and immediately the abyss.
Usually in such cases there is no illumination of the LED panel (matrix). Often the cause of the malfunction is the lack of current in the circuit of the LEDs, for example, their breakdown or closure, or the disruption of contact connections of the LM41-00630A operating connections.

To identify a break in the LED line without disassembling the panel, simply multimeter is impossible. The LEDs are connected in series and to open their transitions, a voltage of several dozen volts will be required. Ideally, for such purposes, the current source will fit. You can open the panel and check each LED separately. Usually, Chinese multimeters are slightly flashing one 3-volt LED if you connect the probe to it in the forward direction (red dipstick - to the anode, black to the cathode). At dual 6-volt indicators, the operation of LED-A can serve as a PN-transition of its emergency stabilion. In the event of a malfunction, LED-and its stabilion will either be broken, either breaks through to / s.
- The TV does not go to the operating mode, does not respond to the remote control. The indicator on the front panel shines constantly, or blinks.
Repair or diagnostics of the BN41-02575B motherboard should be started with checking stabilizers and power converters required for nutrition chip and matrix. If necessary, you should update or replace software (software). If there is no possibility of replacing the MB board (SSB), it is necessary to check the help of its elements - CPU: SDP1604, EMMC: THGBMDG5D1LBAIT, SPI Flash: 25Q40, EEPROM: 25C512. Faulty components should be replaced.
If you suspect a malfunction of the BN40-00331B tuner, it is first necessary to make sure that the software corrects are correct, as well as in the presence of the desired levels of supply voltages and data exchange pulses with the processor over the I2C bus on the appropriate tuner outputs.
The owners and users of the Samsung UE49N5510AU TV should be remembered that independent repairs without special knowledge, skills and qualifications may be fraught with negative consequences that can lead to complete irreparability of the device!
Driver current limit. BN44-00957A, BD94062F. general information
PWM-control driver chip - BD94062F, current sensor - Resistor R9873 1.4 OHM.
To reduce the backlight current, you can increase the value of the R9873 current sensor, for example, from 1.4 to 2 OHM.

Appearance Power Supply
The main features of the Samsung UE49N5510AU device:
The matrix (LED panel) is installed CY-NN049BGLV3H.
To power the backlight LEDs, a transducer combined with a power supply is applied, controlled by the BD94062F SO-16 PWM controller. The keys of the T-252 type are used as the LED-driver strengths.
The formation of the required feed voltages for all SAMSUNG UE49N5510AU TV nodes is carried out by the BN44-00957A power supply module, or its analogues using PFC microcircuits (SO-8), PWM (SO-16) and T-252 strength keys.
Mainboard is the main board (motherboard) is the BN41-02575B module, using CPU chip: SDP1604, EMMC: THGBMDG5D1LBAIT, SPI Flash: 25Q40, EEPROM: 25C512 and others.
The BN40-00331B tuner provides reception of television programs and settings to the channels.
