General repair guidelines for TV LCD
Possible malfunctions
- The SAMSUNG UE32ES6550 TV does not turn on, does not respond to the remote control and the control panel buttons, does not light up or blink indicators.
In some of these cases, a fault is detected in the BN44-00517C power module. It is then necessary to measure its output voltages and, if they are absent, you should check the power switches (D4189, MDD1752) and rectifier diodes of the converters for a short circuit probability.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often 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 SSC2S110 x2, A358F, (PWM SOT23-6 9012M D47DJ), in the absence of visible damage or frank 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.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or the inverter.After checking all the electrolytic capacitors of the filters that are involved in the power supply of the inverter, you must ring in its converter power keys for breakdown and secondary windings of transformers for an open.
Sometimes, for diagnostic purposes, it is necessary to disable the inverter protection. In such cases, special care must be taken during work, and the protection circuits should be restored immediately after the repair is completed.
- 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). 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 - WT61P805, KLM2G1HE3F-B001, K4B2G1646C-HCK0, NTP7412S and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board. Typically, such defects are detected by local heating of the chip.
Before replacing the tuner BN40-00236A, if there is no tuning to the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
It should be remembered! Attempts to self-repair a SAMSUNG UE32ES6550 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-serviceability of the device!

The appearance of the power supply
Main features of the SAMSUNG UE32ES6550 device:
Installed matrix (LCD panel) LE320CSM-C1.
The matrix control uses the Timing Controller (T-CON) V400HK5-CPS1.
To power the backlight, a converter is used, combined with a power supply, controlled by the PLC controller SLC5012M. As power elements of the inverter, keys of the type D5N40, D3N40 are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32ES6550 TV are generated by the BN44-00517C power module or its analogs using SSC2S110 x2, A358F microcircuits (PWM SOT23-6 9012M D47DJ) 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.
