General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the PHILIPS 47PFL6097T / 60 TV, as well as the external elements of the case. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
If the power supply module DPS-130QP A 2722 171 90584 malfunctions, the external manifestations may be different, for example, PHILIPS 47PFL6097T does not turn on at all and there is no indication of the indicator lights on the front panel. With the same symptoms, the stabilizer (converter) of the power supply to the control processor may be faulty. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM DDA010 (8) from the manufacturer.
If the PHILIPS 47PFL6097T does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the backlight circuits of the LC470EUF panel is likely. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the LED driver, and check the LEDs, connecting obviously known good diagnostics.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
In cases of attempts to repair the motherboard UC 222.1 AI1.C, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
Remember! Attempts to self-repair by users of the PHILIPS 47PFL6097T TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the DPS-130QP module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the NCP1608B 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 were 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.

Main features of the PHILIPS 47PFL6097T device:
Installed matrix (LED-panel) LC470EUF (FE) (P1).
The matrix control uses the Timing Controller (T-CON) 6870C-0402C.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the DDA009 PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 47PFL6097T TV are generated by the DPS-130QP power module or its analogs using NCP1608B (PFC), 2QS02G, S101 (6pin), DDA010 (Standby) microcircuits.
