General recommendations for repairing TV LCD
Diagnostics of the malfunction of the TV SONY KDL-32D3000, like all others, it is advisable to start with an external examination of possible changes, both external and internal elements. 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.
Sometimes the SONY KDL-32D3000 TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is the failure of the APS-229 (CH) 1-873-216-12 common power supply module. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and, in the event of a break, the cause should be sought in the power semiconductor elements of the pulsed flyback converter of the main PSU. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch of the K3683, FSF05A60, K3561 converter, which can be installed separately on the radiator, or integrated with a PWM controller.
As a rule, the keys of flyback converters, which use an N-Fet field effect transistor on a separate radiator, or integrated with a FA5501A, CXD9841P, MIP2H2 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 checked by replacing it with a known good one.
When using an active Power Factor Correction (CMC) circuit in the power module, the search for faulty elements is somewhat more complicated.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but there is sound and other functions work, there is a high probability of a malfunction of the inverter (power converter for the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter feeding the inverter should be checked.
In most cases, the diagnosis and repair of the LT320W3S16 Rev.02 inverter is difficult due to the organization of protection, which turns it off in emergency cases to avoid fires during short circuits or breaks in high-voltage circuits and during depressurization of lamps. Often, repairmen block the protection circuits in order to make the necessary measurements at the control points of the inverter to identify the causes of the defect.
It should be remembered that when the protection is turned off, there is always a risk of failure of the power elements of the inverter during diagnosis. After repair, it is necessary to restore all standard converter protection circuits.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software). In cases of attempts to repair the MB (SSB) board, it is necessary to check the health of its elements - XD9890AQ, MSP3417G B8 V3, TMDS341A, TPA31000D2, HY27US08281A, MB91305, 24C256BWP, S29AL016D70TFI01 which may require replacement with new ones.
If the TV works normally from external devices, but does not tune to television channels, the BTD-HF401Z8-597-613-00 tuner may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals, as well as the power supply of varicaps (30-33V).
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.

PSU Advanced
The APS-229 power module is installed in the KDL-32D3000 TV using the PFC (Power Factor Correction) scheme acting as an active filter to eliminate the higher harmonic components of the current consumption. The step-up converter based on the FA5501A PWM controller does not allow the input rectifier filter's electrolytic capacitor to be connected to the network directly through open diodes, when the value of the charge current determines its reactance (about 15-30 ohms at a frequency of 50 Hz). As a result of the conversion, the charging current of the capacitor will be determined in such a way that the envelope of the high-frequency pulses of the input current will repeat the phase and shape of the sine wave of the input voltage. The health check of the PFC unit is carried out by measuring the DC voltage on the capacitor of the rectifier network. In operating mode, it should be around 380V, in standby approximately 300V.
The appearance of the power supply
Main features of the device SONY KDL-32D3000:
Installed matrix (LCD panel) LTZ320WH-LH2 100.
The matrix control uses the Timing Controller (T-CON) 324046WHC6LV2.2.
To power the backlight, an inverter LT320W3S16 is used, it is controlled by the PWM controller OZ9928SN, BA2901F. As power elements of the inverter, keys of the STM4470 type are used.
The necessary supply voltages for all nodes of the SONY KDL-32D3000 TV are generated by the APS-229 power module, or its analogs, using the FA5501A (PFC), CXD9841P, MIP2H2 microchips and power switches of the K3683, FSF05A60, K3561 type.
MainBoard - the main board (motherboard) is a module 1-873-000-11, using microcircuits XD9890AQ, MSP3417G B8 V3, TMDS341A, TPA31000D2, HY27US08281A, MB91305, 24C256BWP, S29AL016D70TFI01 and others.
The BTD-HF401Z 8-597-613-00 tuner provides TV reception and channel tuning.
