PHILIPS 32PFL5322S
General recommendations for repairing TV LCD
Repair of the PHILIPS 32PFL5322S / 60 TV should begin with a careful external examination of all its components and modules. Also subject to inspection are body elements, functional control buttons, screen, cords and connectors. Often, by visible changes, it is possible to determine the further direction of troubleshooting and localization of the defect before the start of the acquisition of oscillograms and the necessary measurements. 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.
Power Module Repair
In the event of a power supply module malfunction, external manifestations may be different, for example, PHILIPS 32PFL5322S / 60 does not turn on at all and there is no indication of control lights on the front panel. 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. In the event that the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and the power switch of the converter, which are often found in breakdown conditions in such situations.
If a breakdown of the power switch of the flyback converter of the power supply unit is detected, it should be remembered that it does not fail by itself for no reason, which should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked by replacement, and also other semiconductor elements (diodes, transistors, zener diodes).
Diagnostics of power modules with a Power Factor Corrector (CMC) is somewhat more complicated and requires a more detailed approach.
Inverter Repair
If the PHILIPS 32PFL5322S / 60 TV does not have an image, but there is sound, the malfunction should be sought in the backlight power converter (inverter). It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overstated ESR.
Diagnostics and repair of the inverter are often complicated by the organization of special protection circuits, which is necessary for fire safety and turns off the inverter in any emergency situation, for example, when the lamps are worn or depressurized. Often, to block a defect, it needs to be locked.
In such cases, special care should be taken during diagnostics, and after completion of all repair work, it is necessary to restore the circuit and the inverter protection for further safe operation of the TV.
Remember! Attempts by the users of the PHILIPS 32PFL5322S / 60 TV to be self-repaired by users without the appropriate qualifications and necessary experience can lead to serious negative consequences!

PSU Advanced
The 32PFL5322S / 60 model uses a PLCD300P3 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 L6562D PWM controller, which eliminates the charge current of the rectifier filter's electrolytic capacitor 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.
