General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE48J6500AU TV does not turn on, does not respond to the remote control and control panel buttons, indicators do not light up and do not blink.
With such manifestations, the BN44-00803A power supply module usually fails. It is then necessary to measure its output voltages and, if they are absent, you should check the power switches (TO-252) and the rectifier diodes of the converters for the probability of a short circuit.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the mains fuse and, less often, the current sensor at the source of the key are most often cut off.
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, PWM, PWM microchips are usually checked by replacing with new ones, or obviously working.
- There is no image, there is sound, all other functions of the TV work. When turned on, the image may sometimes appear for a second.
As a rule, in such cases there is no display backlight. Often the cause is a malfunction of the LEDs (open circuit, short circuit ...), or the connectors of the strips (strings), less often the LED driver is malfunctioning.
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, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-02353B 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). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
If the TV works normally from external devices, but does not tune into television channels, the tuner BN40-00318B 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.
We recommend the owners of the UE48J6500AU 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 UE48J6500AU device:
Installed matrix (LED panel) CY-WJ048CGLV1V.
The matrix control uses the Timing Controller (T-CON) BN41-02229A.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the SAMSUNG UE48J6500AU TV are generated by the BN44-00803A power module or its analogs using PFC, PWM microcircuits, and TO-252 type power switches.
MainBoard - the main board (motherboard) is a BN41-02353B module, using CPU chips: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and others.
The tuner BN40-00318B provides the reception of television programs and tuning to channels.
