General repair guidelines for TV LCD LED
Possible malfunctions
- The SAMSUNG UE55MU6100U TV does not turn on, does not respond to the remote control and buttons on the control panel, does not light up or blink indicators.
Failure in such cases should begin to be sought in the power supply circuits BN44-00807A. It is then necessary to measure its output voltages and, if they are absent, you should check the power switches and rectifier diodes of the converters for the probability of a short circuit.
In case of diode breakdowns in the secondary circuits, the converter can operate in emergency short-circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) SPC7011F, FA6A20, in the absence of external damage and a short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, there is sound, it responds to the remote control. Or the image may appear for a second when turned on and immediately disappears.
In some of these cases, the malfunction is caused by a lack of backlighting on the display. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it does not respond to the remote control.
Repair or diagnostics of the BN41-02568B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - SDP1601, KLM4G1FEPD, K4F8E30 4HBMGCH, 24512FD, 25Q40CLSIP, 25Q80DVSIG, TAS5749M which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltages at the terminals of the tuner BN40-00329B. It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.

Main features of the SAMSUNG UE55MU6100U device:
Installed matrix (LED-panel) CY-GK055HGLV5V.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SLC3011N PWM controller.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE55MU6100U TV is carried out by the BN44-00807A power module, or its analogs using SPC7011F, FA6A20 microcircuits.
MainBoard - the main board (motherboard) is a BN41-02568B module, using microchips SDP1601, KLM4G1FEPD, K4F8E30 4HBMGCH, 24512FD, 25Q40CLSIP, 25Q80DVSIG, TAS5749M and others.
The tuner BN40-00329B provides the reception of television programs and tuning to channels.
