General Recommendations for Repair TV LCD LED
Possible malfunctions
- Samsung UE49MU6103U TV does not turn on, does not respond to the remote control and the control panel buttons, the indicators are not lit and not blink.
Often, in such cases, the BN44-00807F power supply module is faulty. It is necessary to measure its output voltages, and in the case of their absence (complete or partial), it is necessary to check the serviceability of the power keys (TO-220F) of transducers and rectifier diodes for the presence of a possible KZ.
With any breakdowns of semiconductors in secondary circuits, the converter usually can normally work in a short circuit emergency mode. There are no output voltages. And when CZ in the power elements of the primary chain, as a rule, a network fuse is broken and the current sensor in the source of the key.
The mos-fet key breaks used in pulse sources is often caused by the faults of other elements, for example, in the power supply circuit of the PWM regulator, in frequency and damping chains, as well as in the negative feedback of stabilization. PWM (PWM) PFC chips, PWM is usually checked by replacing new or obviously good.
- The image is absent, but there is sound and reaction to the remote control. Either for a second, the image may appear immediately after switching on.
As a rule, in this case, the LED panel light is faulty. Often the reason for the malfunction is the lack of current in the chain of the LEDs, for example, their breakdown or closure, or a violation of the contact connections of the LM41-00334A plank connections, LM41-00335A, BN96-40782A.
It should be remembered that to determine the opening in the LED rules, without disassembling the panel, using the tester or the multimeter is not possible without an additional device, for example, the current source. To open all PN transitions immediately, connected in series may require a voltage of several dozen volts. Then it is necessary to open the panel and check each LED multimeter separately. If the capabilities of your multimeter do not allow you to open LED in the forward direction or dual LEDs are used, then the PN-transition of emergency stabilion can serve as an indicator of health. In the event of a malfunction, the LED-A PN-transition of Stabilon will either be broken or breaking through in k / s.
If Samsung UE49MU6103U has no image, but there is sound, often the CY-GM049HGLV1V display illumination does not work. Moreover, the LEDs usually fail within the panel, less often a LED driver.
In such cases, you can see the barely noticeable image with successful appearance of external lighting on the screen.
To replace LEDs, the CY-GM049HGLV1V LCD panel disassembly is required - a process requiring experience and qualifications from the Wizard. We do not recommend producing such works on your own owners of televisions and masters that do not have the experience of repairing LCD panels,
READ HOW TO REPAIR THE TV LED BACKLIGHT --------------> HERE.
If there is no image, and the backlight works - the screen when turned on it becomes a little lighter, and in the open TV it is visible light through the holes in the panel housing.
In this case, the panel may also be a faulty - damage to slats, loops, for example, as a consequence of moisture from hitting the screen after unsuccessful screening of the screen, the T-CON board (timing controller) may be faulty. But it is often faulty and the main board of MainBoard BN41-02568B is also possible, and the software failure is also possible.
Then, first of all, it is necessary to check the supply voltage of the panel, the fuses on the T-CON board, as well as the supply and reference voltages of column and lowercase drivers - VGH, VGL, VCOM.
If these measurements within the normal range, the oscilloscope is necessary to track the passage of LVDS signals from Mainboard BN41-02568B, as well as synchronizing signals to the strober with drivers.
Spilled or unsuccessfully floated screens of LED-TVs have the opportunity to restore, about half of the cases, usually, if there are no significant damage in loops and panel strobes.
- The indicator on the front panel blinks, the TV is not turned on in the operating mode, the remote control does not respond.
Repair or diagnostics of the BN41-02568B motherboard should be started with checking stabilizers and power converters needed to power the chip and matrix. If necessary, you should update or replace software (software). Repair of board and replacing the SDP1601 chip, KLM4G1Fepd, 25Q40CLSIP, 25Q80DVSIG, TAS5749M are made in the presence of the necessary equipment, and the corresponding element base. Malfunctions associated with the use of BGA processor soldering technologies can be localized by the warm-up method.
Before replacing the BN40-00331A tuner, if there is no setting to the channels, before you need to check the software and supply voltage at its outputs. It is also necessary to make sure that the data exchange of the tuner and the processor over the I2C bus
Attention to the owners of televisions! SAMSUNG UE49MU6103U independent repair attempts are not recommended by the manufacturer and can lead to serious negative consequences!

Appearance Power Supply
The main features of the Samsung UE49MU6103U device:
The matrix (LED panel) is installed CY-GM049HGLV1V.
To power the backlight LEDs, a transducer combined with a power supply is applied, controlled by the SLC3011M SO-14 STEPUP switch controller. The keys of the T-220F type are used as the LED driver power elements.
The formation of the required supply voltages for all SAMSUNG UE49MU6103U TV nodes is performed by the BN44-00807F power supply module, or its analogues using PFC, PWM microcircuits and T-220F power keys.
Mainboard is the main board (motherboard) is the BN41-02568B module, using the SDP1601, KLM4G1FepD, 25Q40CLSIP, 25Q80DVSIG chip, 25Q80DVSIG, TAS5749M and others.
The BN40-00331A tuner provides receiving television programs and settings to the channels.
