General recommendations for repairing TV LCD
Diagnostics of malfunctions and repairs PHILIPS 32PFL5522D / 12, as well as other electronic devices, it is recommended to start with an external examination of the external and internal elements. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
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 DPS-182BP B power module is defective and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of standby power. 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. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors P20NM60FP, F3NK80Z, which are often found in such a state of breakdown.
A breakdown of the power switch of the pulse converter is often triggered by other elements, for example, in the stabilization or control circuits of this switch, as well as by the damper elements in its drain and TPI winding.
If the PHILIPS 32PFL5522D does not have an image, but there is sound, there is a possibility of a malfunction of the backlight or power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working. 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.
Repair or diagnostics of the 313912362611 WK647.3 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, you should update the software (software). Board repair and chip replacement PNX8314HS / 102; K4S281632I; M29W320ET; M30300AGP are produced with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
Before changing the TD1316AF / IHP-2 tuner, if it is not possible to tune to television channels, make sure that there are supply voltages that must be measured at the corresponding tuner pins and check the software for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
It should be remembered! Attempts to repair the PHILIPS 32PFL5522D TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

PSU Advanced
The 32PFL5522D / 12 model uses the DPS-182BP 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.

Main features of the PHILIPS 32PFL5522D device:
Installed matrix (LCD panel) LK315T3LZ53.
The matrix control uses the Timing Controller (T-CON) X3593TP.
To power the backlight, an inverter RDENC2287TPZ is used, it is controlled by the BD9777 PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 32PFL5522D TV are generated by the DPS-182BP power supply module or its analogs using L6598 (PWM Resonant 16pin), L6562D (PFC), NCP1207AD microcircuits and power switches of the type P10NK60ZFP, P20NM60FP (PFC80, F3).
