General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE46D5000PW 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.
In some of these cases, the main switching power supply, the BN44-00422A module, is faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the operability of the power switches of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often 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 circuits (PWM) SPC7011F = FA5695N (PFC), D2011K (Standby), FSFR1700XS (PWM) are usually checked by replacing with new, or obviously working.
- There is no image, there is sound, there is a reaction to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
In such cases, the most likely malfunction of the backlight elements 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 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 BN41-01661B 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). In cases of attempts to repair the MB board (SSB), it is necessary to check the serviceability of its elements - K4B1G1646G-BCH9, WT61P805, NTP-7411S which may require replacement with new ones. If the 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).
Before replacing the tuner BN40-00196A DT0S40FVH082, 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
It should be remembered! Attempts to self-repair a TV SAMSUNG UE46D5000PW, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-serviceability of the device!

The appearance of the power supply
Main features of the SAMSUNG UE46D5000PW device:
Installed matrix (LED-panel) LTG460HN01-V.
The matrix control uses the Timing Controller (T-CON) S100FAPC2LV0.3.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the SEM5025 PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE46D5000PW television are generated by the BN44-00422A power supply module or its analogs using microchips SPC7011F = FA5695N (PFC), D2011K (Standby), FSFR1700XS (PWM).
MainBoard - the main board (motherboard) is a BN41-01661B module, using K4B1G1646G-BCH9, WT61P805, NTP-7411S and others.
The tuner BN40-00196A DT0S40FVH082 provides the reception of television programs and tuning to channels.
