General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE46H6203AK 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.
With such manifestations, a malfunction is most likely to be detected in the BN44-00766A power supply module. It is necessary to measure its output voltages and, if they are absent, to check for short-circuit probabilities in the converters, power switches and rectifier diodes.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse 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), in the absence of external damage and 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, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
The most likely in these cases is a malfunction of the LED backlight. 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 is impossible to check the LED line for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source. Having disassembled the panel, it is necessary to check each LED separately. Chinese multimeters, as a rule, light up a single 3-volt LED in the forward direction. In the case of using dual 6-volt LEDs, the PN junction of its protective zener diode can serve as a health indicator. In faulty LEDs, the zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-02241A 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 - SPI Flash: 25Q40CL, EEPROM: ATMLH 416 2EC, SOUND: TAS5747PHPR. Defective components should be replaced.
If the TV works normally from external devices, but does not tune into television channels, the tuner BN41-02241A 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.
Attention! For users and owners of UE46H6203AK TVs who do not have the appropriate qualifications, knowledge and experience, we categorically do not recommend attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

The appearance of the power supply
Main features of the SAMSUNG UE46H6203AK device:
Installed matrix (LED panel) CY-DF460CSLV1V.
The matrix control uses the Timing Controller (T-CON) BN96-24429A.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the SEM4011 PWM controller.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE46H6203AK TV is carried out by the power module BN44-00766A, or its analogues.
MainBoard - the main board (motherboard) is a BN41-02241A module using SPI Flash chips: 25Q40CL, EEPROM: ATMLH 416 2EC, SOUND: TAS5747PHPR and others.
The tuner BN41-02241A provides the reception of television programs and tuning to channels.
