General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE46F6200AK 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.
Often in such cases, the BN44-00616A power module is faulty. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches and rectifier diodes in the converters for possible breakdown.
In case of breakdowns of semiconductors in the secondary circuits, the converter can emergencyly operate in the short circuit mode, and during short circuit in the power elements of the primary circuit, the main fuse often breaks.
The breakdown of Mos-Fet keys used in pulsed sources is sometimes caused by malfunctions of other elements, for example, elements supplying a PWM controller, frequency-setting, damper, as well as elements of the Negative Stabilization Feedback.
PWM Chips (PWM) SPS1013P is usually checked by replacement.
- 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.
To check the LED strips, to open all the transitions of the LEDs, several tens of volts or more are needed, it is best to use a current source for such purposes. The breakage of several PN junctions connected in series cannot be detected with a multimeter or tester. In such cases, it is necessary to open the panel and check each LED. If your multimeter cannot open the LED transitions in forward bias, you can sometimes detect the presence of a PN junction of the protective zener diode by connecting the probes in the opposite direction. If the zener diode is broken or broken in short-circuit, then the LED is faulty and needs to be replaced.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the BN41-01958A 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). If it is not possible to replace the MB board (SSB), you need to check the health of its elements - SEMS30, SPI FLASH: W25Q40, SDRAM: K4B2G1646E. Defective components should be replaced.
If the TV works normally from external devices, but does not tune into television channels, the tuner BN40-00262A may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
Owners and users of the SAMSUNG UE46F6200AK TV should remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The appearance of the power supply
Main features of the SAMSUNG UE46F6200AK device:
Installed matrix (LED panel) CY-HF460BGLV2V.
The matrix control uses the Timing Controller (T-CON) LSF460HN02.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by a PWM controller SLC5012M, SMS1013.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE46F6200AK TV is carried out by the BN44-00616A power module, or its analogs using SPS1013P microcircuits.
MainBoard - the main board (motherboard) is a BN41-01958A module, using SEMS30, SPI FLASH: W25Q40, SDRAM: K4B2G1646E and others.
The tuner BN40-00262A provides the reception of television programs and tuning to channels.
