General repair guidelines for TV LCD LED
Possible malfunctions
- The SAMSUNG UE46C6000 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.
With such manifestations, the BN44-00357B power module usually fails. It is necessary to measure its output voltages, and if they are absent, check the operability of power switches (FCPF11N60T, FQPF9N50CT) of converters and rectifier diodes for a short circuit probability.
In case of breakdowns of diodes 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.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM microchips (PWM) FA5591N, ICE3BR0665J, ICE1HS01G are usually checked by replacing with new ones, or obviously working.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
Usually in such cases, a malfunction is detected in the backlight nodes of the LED panel. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
It should be remembered that it is not possible to determine the open circuit in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required. Then it is necessary to open the panel and check each LED separately with a multimeter. If the capabilities of your multimeter do not allow you to open the LED in the forward direction or dual LEd are used, then the PN junction of the emergency zener diode can indirectly serve as a health indicator. In case of LED-a malfunction, the zener diode PN junction will either be cut off or broken into short-circuit.
- The TV does not turn on, the indicator signals standby or working mode, or blinks.
Repair or diagnostics of the BN41-01444B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, you should update or replace the software (software). When repairing an MB board, you need to check its components SDP92, WT61P802, 24C02, 24C256, KFG8GH6U4M. Defective items should be replaced. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
Before replacing the DT0S40CVL081A BN40-00173A tuner, if there is no tuning for the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Attention to users! Self-repair of a SAMSUNG UE46C6000 TV without the appropriate qualifications and necessary experience can lead to its complete non-repairability!

The appearance of the MainBoard BN41-01444B is shown in the figure below:BN41-01444B
BN41-01444B can be used in TVs:
SAMSUNG UE32C6000RW UE32C6000 (Panel LTF320HF02), SAMSUNG UE32C6700 UE32C6700US (Panel LTF320HF02 (BN07-00858A)), SAMSUNG UE37C6000 UE37C6000RW (Panel T370FBE2-DA), SAMSUNG UE46C6000 UE46C6000RW (Panel LTF460HJ03).
Main features of the SAMSUNG UE46C6000 device:
Installed matrix (LED-panel) LTF460HJ03.
The matrix control uses the Timing Controller (T-CON) V460H1-CH7.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the MAP3201 PWM controller. As the power elements of the LED driver, keys of the FQU5N40TU type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE46C6000 TV are generated by the BN44-00357B power supply module or its analogs using FA5591N, ICE3BR0665J, ICE1HS01G microcircuits and power switches of the FCPF11N60T, FQPF9N50CT type.
MainBoard - the main board (motherboard) is a module BN41-01444B, using microchips SDP92, WT61P802, 24C02, 24C256, KFG8GH6U4M and others.
Tuner DT0S40CVL081A BN40-00173A provides the reception of television programs and tuning to channels.
