General recommendations for repairing TV LCD
Repair of TVs, as well as other devices, it is advisable to start with an external examination. In some cases, visible external damage to the elements can indicate the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of electronic circuit nodes. Electrolytic capacitors of filters with a swollen casing, as well as ring cracks formed in the soldered leads of heating elements, or a layer of coal on burnt resistors 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 PLCD170PS09 - 3122 423 32396, 3122 427 24851 power supply module is defective and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of standby power. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse is broken, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
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 TEA1601T PWM controller microcircuit (16) are subject to verification, which it is desirable to verify by replacement.
In cases where the PHILIPS 32PFL5403D TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of an inverter (converter for powering the backlight) malfunction. 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. It is necessary to take into account that in cases of inverter protection shutdown (in order to be able to diagnose) there is a risk of failure of the inverter power elements and take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
Motherboard 313912364161 v3 W815.5 - 313912364171 v3 (313926861291) must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or lights up constantly. In such cases, if the converters or power regulators of the microcircuit are working, a software update may be necessary. If it is not possible to replace the MB board (SSB), you need to check the health of its elements - PNX8541E1 / M1 / 2414, NAND512W3A2CN6, SOUND: TDA8932BTW. Defective components should be replaced.
If the TV works normally from external devices, but does not tune into television channels, the TD1716F tuner may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
Attention to the owners! Attempts at self-repair of the PHILIPS 32PFL5403D TV are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the power supply
Key Features of PHILIPS 32PFL5403D:
Installed matrix (LCD panel) LK315T3LZ93Q.
The matrix management uses the Timing Controller (T-CON) CPWBX.
To power the backlight used inverter RDENC2540TPZF.
The necessary supply voltages for all nodes of the PHILIPS 32PFL5403D TV are generated by the PLCD170PS09 power module or its analogs using TEA1601T microcircuits (16).
MainBoard - the main board (motherboard) is a module 313912364161, using chips PNX8541E1 / M1 / 2414, NAND512W3A2CN6, SOUND: TDA8932BTW and others.
The TD1716F tuner provides television reception and channel tuning.
