General recommendations for repairing TV LCD
Repair of the SONY KDL-32S3000 K TV is advisable to start with an external inspection of all its components, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. Many visible signs make it possible to determine the future direction of troubleshooting and localization of the defect. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a hint in the assumptions about the causes and consequences of the malfunction.
In cases where the SONY KDL-32S3000 K TV does not turn on, does not respond to the remote control and buttons, any indicators on the front panel do not light up or blink, and there are no sounds and no signs of operability when turning on, the A- power supply module is most likely faulty 1257-921-A G1 BOARD, COMPLETE or, which is much less common, there is no processor power on the motherboard. When diagnosing and repairing the A-1257-921-A G1 BOARD, COMPLETE power supply, it is first necessary to check the fuse, and if it breaks, the 2SK3469-01MR-F111 power switch and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
As a rule, the keys of flyback converters, which are used as an N-Fet field effect transistor on a separate radiator, or integrated with the MCZ3001DB, MIP2H2, MM1530ATT, PQ1CG2032FZ PWM controller in a single chip, are quite reliable and rarely fail for no reason. The reasons for the breakdown of the key should be sought by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
If the power module uses an active KKM circuit (power factor control), troubleshooting is somewhat more complicated.
In cases where the SONY KDL-32S3000 K TV has lost an image, and the sound is there and all the other functions are functional, there is a possibility of a malfunction of the inverter (converter for powering the backlight). When you turn on the TV, the image may appear briefly and immediately disappear. It must be borne in mind that with such manifestations, the lamps themselves also fail, the malfunction of which can be detected by replacement, by connecting to the connectors for diagnostics that are known to be serviceable and suitable in power.
The operation of the power circuits of the inverter and the backlight in the normal mode are controlled by special protection, which is organized for fire safety, for example, to disconnect during short circuits or breaks in high-voltage connections or when the lamps are depressurized. This protection makes it difficult to diagnose and repair the inverter.
It should be remembered that when the protection is turned off, there is always a risk of failure of the inverter power elements during diagnosis. After repair, it is necessary to restore all standard converter protection circuits.
Repair or diagnostics of the A-1309-278-A D2 BOARD COMPLETE motherboard should be started by checking the power conditioners. If necessary, you should update the software (software).
Owners and users of the SONY KDL-32S3000 K TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The appearance of MainBoard 1-873-891-13 is shown in the figure below:1-873-891-13
1-873-891-13 can be used in TVs:
SONY KDL-32S3000 K (Panel T315XW02 V.E), SONY KDL-40S3000 (Panel LTZ400WT-LH3 001).
The appearance of the power supply
Main features of the device SONY KDL-32S3000:
Installed matrix (LCD panel) T315XW02 V.E.
The matrix control uses the Timing Controller (T-CON) FS-HBC2L.
To power the backlight, a DARFON inverter is used, it is controlled by the OZ9966SN PWM controller (24). A transformer 8801A95EA05 (HF) is installed in the inverter converter. As power elements of the inverter, keys of the AOD4184 type (3) are used.
The necessary supply voltages for all nodes of the SONY KDL-32S3000 TV are generated by the power module 1-872-334-13, or its analogs using microchips MCZ3001DB, MIP2H2, MM1530ATT, PQ1CG2032FZ and power switches of the type 2SK3469-01MR-F111.
MainBoard - the main board (motherboard) is a module 1-873-891-13, using microcircuits D61123F1-100, PLQFP208, MC74LVX138DTR2, TDA9973A and others.
The BTD-HF401Z (01) tuner allows you to receive television programs and tune to channels.
