PHILIPS 32PFL9613
General recommendations for repairing TV LCD
TV PHILIPS 32PFL9613, like other electronic devices, it is advisable to start repairing from inspection of external and internal elements. Specific external damage to the elements can sometimes prompt further actions to determine the malfunction of the TV and localize the defect before starting the necessary measurements and taking waveforms. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
Power Module Repair
In the case when the 32PFL9613 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink bulbs and does not show any signs of operability, most likely in this case the DPS-182CP power supply module is faulty. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power switch and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
The reasons for the breakdown of the power switch of the flyback converter of the power module can be different, for example, a malfunction of semiconductor elements or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or breakage of the resistors in its bundle.
When using the Active Power Factor Correction (CMC) circuitry in the power module, the search for faulty elements is somewhat more complicated.
Inverter Repair
If there is no image when you turn on the PHILIPS 32PFL9613, or it appears for a second and disappears completely, but there is sound, most likely either the backlight or the power converter (inverter) are malfunctioning. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
In most cases, the diagnosis and repair of the U84PA-E0006673C inverter is difficult due to the organization of protection, which turns it off in emergency cases to avoid fires during short circuits or breaks in high-voltage circuits and during depressurization of lamps. Often, repairmen block the protection circuits in order to make the necessary measurements at the control points of the inverter to identify the causes of the defect.
In these cases, special care must be taken in view of the risk of failure of the power elements. After completing all repair work, it is imperative to restore the protection circuits for full and safe further operation of the TV by the user.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the DPS-182CP module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the NCP1606 PWM controller. The reactance of an electrolytic capacitor of a line filter at a frequency of 50-60 Hz is usually not more than 20-30 ohms and its charge directly from the network through open diodes could reach tens of amperes per pulse if no filtering was applied.
As a result of the PFC conversion, an increased voltage on the capacitor (about 380V) cannot directly open the rectifier diodes, on the anode of which the voltage will always be slightly less (about 300V) and then its charging current will always be limited by the elements of the PWM controller. As a result, the envelope of the high-frequency pulses of the consumed current will repeat the shape and phase of the input sinusoidal voltage. The presence of an increased voltage (+ 380V) on the network capacitor indicates the serviceability of the PFC node.
