General repair guidelines for TV LCD LED
Repair of the SONY KDL-32EX600 TV should begin with a fault diagnosis, which involves a careful examination of the external and internal elements of the device. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Electrolytic capacitors of filters with a swollen case, as well as ring cracks or a layer of coal on burned-out resistors formed in the soldered terminals of the heating elements, sometimes tell the repairman the causes of the malfunction and possible consequences.
In the case when the KDL-32EX600 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink bulbs and does not show any signs of operability, the GE3 APS-272 / CM power supply module is probably faulty in this case. If it is serviceable with such manifestations, it is necessary to check the power supply stabilizer (converter) of the processor on the motherboard. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors K15A500, ATP212 0C4, ATP201 0C2, which are often found in such a state of breakdown.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller chip MIP2H2 (7), A3809AM (24), A109F (8) 2904, LV5768, A109I (8) 2904, which it is desirable to check by replacement, are subject to verification.
If there is no image when you turn on the SONY KDL-32EX600, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the V315H3-LE1 Rev.C1 LED 181127611 // LTY320HM02 12v, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
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.
Repair of the BEN A1798646A motherboard must begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing elements TPA3110D2 (28), PS54225 (14), 393 (8), LVC541A (20), LVC245A (20), TDA19997HL / C1, PNX85433EH1 requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
The malfunction of the ENGS7401D5F tuner is established after checking the software and all the supply voltages at its terminals, including the varicap supply voltage (30-33V).
Remember! Attempts to self-repair by users of the SONY KDL-32EX600 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

1-881-019-13 can be used in TVs:
SONY KDL-32EX401 (Panel LTY320HM03), SONY KDL-32EX600 (Panel V315H3-LE1), SONY KDL-37EX402 (Panel T370HW03 V.8 181107411).
PSU Advanced
The APS-272 power module is made using the Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced into the power supply by the device. The PFC node is a Step-Up Converter based on a A3809AM 24pin PWM controller that evenly distributes high-frequency pulses of the charging current of the electrolytic capacitor of the rectifier filter of the mains voltage over a period of 50 Hz. The current of its charge in this case will already be determined not by its reactance (usually 10-30 ohms for the network frequency), but by the elements of the converter. As a result, a change in the amplitude of the pulses (envelope) of the consumed current of the converter will repeat the shape and phase of the input sinusoidal voltage. The availability of an increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.
The appearance of the power supply
Main features of the device SONY KDL-32EX600:
Installed matrix (LED-panel) V315H3-LE1 or LTY320HM02 12v.
The matrix control uses the Timing Controller (T-CON) V315H3-CE1.
The LED driver APS-272 is used to power the backlight LEDs, it is controlled by the PWM controller A3809AM (24) ,. The transformer 1-445-849-11 is installed in the converter of the LED driver. As power elements of the LED driver, keys of the type K4096, K4096 are used.
The necessary supply voltages for all nodes of the SONY KDL-32EX600 TV are generated by the APS-272 power module, or its analogs using microchips MIP2H2 (7), CXA3809M (PFC & PWM resonant), A109F (8), 2904, LV5768 and power switches of the type K15A500, ATP212 0C4, ATP201 0C2,.
