General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE32D6510WS 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.
Typically, with such manifestations, the defect is caused by faulty elements in the main power module BN44-00458B. It is necessary to measure its output voltages and, if they are absent, to check the operability of power switches (MDF10N60G (PFC)) and rectifier diodes in the converters for possible breakdown.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet power switches used in switching power supplies sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode or create an excess of the maximum permissible key parameters. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers STR-A6052M, SPC7011F, FSFR1800XSL, in the absence of visible damage or obvious short-circuit between the terminals, are checked by replacing with new, or obviously working.
- There is no image, there is sound, there is a reaction to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
In some of these cases, a malfunction is caused by a lack of display backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
When trying to identify a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
- 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 BN41-01587E 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 elements SDP1001, SDP1005, SDP94, SIL9489ACTU, K4B2G1646C-HCH9, EPM240T100C4N. BGA chip malfunctions are usually easy to detect by warming up.
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltage at the terminals of the tuner BN40-00217A. It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.
Attention! For users and owners of UE32D6510WS 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 UE32D6510WS 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 a power supply unit, controlled by the SLC3011M PWM controller. As power elements of the LED driver, keys of the MDF12N50 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32D6510WS 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 provides the reception of television programs and tuning to channels.
