General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG 32D6510 TV does not turn on. There is no reaction to the remote control and to the control buttons from the front panel. Indicator lights do not light or flash.
In such cases, the BN44-00458B power supply is usually faulty. It is necessary to measure the secondary output voltage, and in case of their absence, check the health of the power switches (MDF10N60G (PFC)) of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during a short circuit in the 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. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may also be PWM (PWM) STR-A6052M, SPC7011F, FSFR1800XSL. It is checked only by replacement with a known good one.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Usually, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as a health indicator. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The indicator blinks or glows constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the BN41-01587E 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 some cases, to repair the MB board (SSB), it may be necessary to replace the chips - SDP1001, SDP1005, SDP94, SIL9489ACTU, K4B2G1646C-HCH9, EPM240T100C4N with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
If the tuner BN40-00217A DNSS243VH142A is suspected of malfunction, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
For 32D6510 TV owners, we recommend that you contact qualified specialists with the necessary work experience for repairs! Attempts to repair it yourself without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of the power supply
Main features of the SAMSUNG 32D6510 device:
Installed matrix (LED panel) LD320CSC-C2.
The matrix control uses the Timing Controller (T-CON) V460HK1-C01.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the PLC controller SLC3011M. As power elements of the LED driver, keys of the MDF12N50 type are used.
The necessary supply voltages for all nodes of the SAMSUNG 32D6510 TV are generated by the BN44-00458B power supply module or its analogs using the STR-A6052M, SPC7011F, FSFR1800XSL microcircuits and MDF10N60G (PFC) type power switches.
MainBoard - the main board (motherboard) is a module BN41-01587E, using microchips SDP1001, SDP1005, SDP94, SIL9489ACTU, K4B2G1646C-HCH9, EPM240T100C4N and others.
The tuner BN40-00217A DNSS243VH142A provides the reception of television programs and tuning to channels.
