General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE32ES6540 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.
Failure in such cases should begin to be looked for in the power source circuits BN44-00517C. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary to check the power switches (D4189, MDD175) and rectifier diodes for a possible partial or complete breakdown.
In case of any breakdown of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And during short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
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) SSC2S110 x2, A358F, (PWM SOT23-6), 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. Or the image may appear for a second when turned on and immediately disappears.
As a rule, in such cases there is no display backlight. 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. Typically, 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 BN41-01807A 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 cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its chips WT61P805, KLM2G1HE3F-B001, K4B2G1646C-HCK0, NTP7412S and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
Before changing the tuner BN40-00236A, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding terminals of the tuner and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Attention! For users and owners of UE32ES6540 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 UE32ES6540 device:
Installed matrix (LED-panel) LE320CSM-C1.
The matrix control uses the Timing Controller (T-CON) V400HK5-CPS1.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SLC5012M PWM controller. As power elements of the LED driver, keys of the type D5N40, D3N40 are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32ES6540 TV are generated by the BN44-00517C power module or its analogs using SSC2S110 x2, A358F, (PWM SOT23-6) microcircuits and power switches of the D4189, MDD1752 type.
MainBoard - the main board (motherboard) is a BN41-01807A module, using microchips WT61P805, KLM2G1HE3F-B001, K4B2G1646C-HCK0, NTP7412S and others.
The tuner BN40-00236A provides the reception of television programs and tuning to channels.
