General recommendations for repairing TV LCD
Repair of a SONY KDL-40P3000 TV is advisable to start with an external examination of all its constituent elements, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. Any external damage can sometimes prompt the repairman to take further steps to determine the malfunction of the TV and localize the defect. 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.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain chance that the power module 1-874-220-11, A-1276-474-A is faulty and needs repair . Sometimes with similar manifestations a problem can only occur in the absence of processor power, but this happens much less often. In this case, the diagnosis and repair of the common power supply should always be started by checking the mains fuse. When it is broken, it is advisable to check for a breakdown, first of all, all power semiconductor elements of the converter and the rectifier diode bridge of the network, as well as the large electrolytic capacitor of the filter of the network rectifier and the key transistor 2SK3797, 2SK3561, FSF05A60.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors of the N-FET type 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, either dried electrolytic capacitors or dangling resistors of the primary circuit of the PSU, involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller microcircuit CXD9841P, MIP2H2, FA5501A, TDA8932BT, which it is desirable to check by replacement, are subject to verification.
When using a power factor correction unit (PFC) in the power modules, troubleshooting becomes somewhat more complicated and requires additional experience and knowledge of their operation.
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 supplying the inverter should be checked.
Repair of the inverter DARFON 4H.V2358.101 / B, 4H.V2358.111 / A 1-874-224-11, A-1276-478-A can often be somewhat complicated by the use of special protection circuits that are designed to disconnect it in emergency cases for fire safety during depressurization of lamps, or short circuits or breaks in high-voltage circuits and connections. Sometimes it becomes necessary for diagnostic purposes to block the protection circuits in order to be able to make the necessary measurements at the control points of the circuit.
It should be remembered that in such cases there is a risk of failure of the power elements of the inverter and to take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
Repair of the motherboard 1-874-223-12, A-1276-477-A 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. If it is not possible to replace the MB board (SSB), you need to check the health of its elements - CXD9922R, TDA9973AHL / 8/12, 24C32W1, CXD1968R, HY825DC256160CE-6, TPC8109 x2. Defective components should be replaced.
Before changing the tuner 8-597-585-10, BTP-HC401 (10), if it is not possible to tune to television channels, make sure that there are supply voltages, including varicap supply (30-33V), which must be measured with
corresponding tuner conclusions.
We recommend the owners of the KDL-40P3000 TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

PSU Advanced
The KDL-40P3000 model uses a 1-874-220-11 power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, this is a boost converter based on the FA5501A PWM controller, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes, when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.
The appearance of the power supply
Main features of the device SONY KDL-40P3000:
Installed matrix (LCD-panel) T400XW01 V0.
The matrix control uses the Timing Controller (T-CON) T400XW01.
To power the backlight, a DARFON inverter is used, it is controlled by the PWM controller BA10339F, LX1692BIDW. As power elements of the inverter, keys of the 2SK3569 type are used.
The necessary supply voltages for all nodes of the SONY KDL-40P3000 TV are generated by the power module 1-874-220-11, or its analogs using microcircuits CXD9841P, MIP2H2, FA5501A (PFC), TDA8932BT and power switches of the type 2SK3797, 2SK3561, FSF05A60.
