General recommendations for repairing TV LCD
TV PHILIPS 32PFL3606H / 60, like other electronic devices, it is advisable to start repairing from inspection of external and internal elements. 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. Experienced repairmen are often aware of the causes of the defect and the possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
Power Module Repair
In the absence of any signs of operability, when the PHILIPS 32PFL3606H / 60 does not turn on and does not signal anything with the control lights on the panel, the power supply module 715G4801-P1A-H20-002U is most likely faulty. 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 the power switch of the P10NK60ZFP, 3N80 ,, converter, which are often found in such a breakdown state in such situations.
It should be remembered that the N-FET keys used in flyback converters rarely fail without their own sake without any reasons that must be sought by checking other elements of the circuit. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip TNY277PN (7), 1271A (8), AN6961 (8) can also cause a breakdown of the power switch of the converter.
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.
Inverter Repair
If the PHILIPS 32PFL3606H / 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.
The diagnosis of the 715G4801-P1A-H20-002U 996510042073 inverter can be difficult due to the protection being triggered by the designers to prevent negative consequences or fires in emergency cases, for example, during short circuits or open circuits in the lamp power supply circuit, as well as their possible leakage. To make the necessary measurements at control points or to take the necessary waveforms, repairmen have to block the protection circuits in order to be able to diagnose.
When diagnosing with disabled protection, special precautions must be observed, because there is a risk of failure of the power elements of the inverter. After the diagnosis, it is imperative to restore the protection circuits for the inverter to operate normally.
Repair Main Board
On the motherboard 715G46009-000-005B 996510042075, in the event of a malfunction, you should first check the operation of all the stabilizers or power converters of the microcircuits and, if necessary, update the software (software). In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - STA339BW, TMDS251, 17113E, 17119E, 9668E, tuner TDTK-G731D with new or obviously working ones.
Owners of the 32PFL3606H / 60 TV are recommended for repair only contact qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

PSU Advanced
The 32PFL3606H / 60 model uses a 715G4801-P1A-H20-002U power supply unit using the PFC (Power Factor Correction) node - an active filter of higher harmonics of the current consumption. In fact, this is a step-up converter based on the AN6961 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.
