General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE65MU6300U TV does not turn on. There are no signs of operability. The indicators on the front panel do not light or flash, the TV does not respond to the remote control and control buttons.
Most often, with such manifestations, the main power module BN44-00808D is found to be faulty. 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 any breakdown of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And with a short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback circuits (OOS) of stabilization. PWM controllers (PWM), if they do not have visible damage to the chassis and open short circuit between the terminals, are usually checked by replacement.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason can be both in the power of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
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). Board repair and chip replacement SDP1601 ver.05, KLM461FEPD, K4F8E30 4HBMGCH, 24512FD, 25Q40CLSIP, 25Q80DVSIG, TAS5749M are carried out with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
The malfunction of the tuner BN40-00329B is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
We recommend the owners of the UE65MU6300U TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE65MU6300U device:
Installed matrix (LED-panel) CY-WK066HGLV1V.
The matrix control uses the Timing Controller (T-CON) integrated.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE65MU6300U TV is carried out by the power module BN44-00808D, or its analogues.
MainBoard - the main board (motherboard) is a BN41-02568B module, using microchips SDP1601 ver.05, KLM4G1FEPD, K4F8E30 4HBMGCH, 24512FD, 25Q40CLSIP, 25Q80DVSIG, TAS5749M and others.
The tuner BN40-00329B provides the reception of television programs and tuning to channels.
