General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE55J6200AU TV 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, in some cases, the BN44-00704E power module is faulty. Then we recommend that you measure its output voltages and, if they are absent, you should check the health of the power switches and rectifier diodes of the converters for a probable short circuit.
In the event of a breakdown in the secondary circuits of the converter, it can usually fail in short circuit mode, and in case of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most 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 microchips (PWM) FA6A01 are usually checked by replacing with new, or obviously working.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
The most likely in these cases is a malfunction of the LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
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 failure, 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 BN41-02353B 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). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the CPU elements: SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA. BGA chip malfunctions are usually easy to detect by warming up.
The malfunction of the tuner BN40-00318B is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
TV users and owners need to remember that attempts to self-repair a SAMSUNG UE55J6200AU TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

The appearance of the power supply
Main features of the SAMSUNG UE55J6200AU device:
Installed matrix (LED panel) T550HVF02.1 or CY-GH055CSLVGV.
The matrix control uses the Timing Controller (T-CON) T650HVN05.7.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE55J6200AU TV is carried out by the BN44-00704E power module, or its analogs using FA6A01 microcircuits.
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.
