General repair guidelines for TV LCD LED
Malfunctions of the PLDK-P107B 272217190604 GL-PSL55-3-3D-Full power supply module can be expressed in different ways, for example, the PHILIPS 55PFL6007T does not turn on at all and the control lights on its front panel do not light up and do not blink, there are no signs of operability. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the filters of the secondary rectifiers (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller microcircuit SCY99102BDR2G, L6599, FSL106MR, which it is desirable to check by replacement, are subject to verification.
If the PHILIPS 55PFL6007T does not have an image, but there is sound, the C550EUF (FE) (P1) panel backlight LEDs or their power converter may malfunction - the LED driver.
In case of breaks in the LED circuit, a complete disassembly of the panel is required, the LEDs are checked for an open circuit, as well as the reliability of the connections in the connectors and rations of the terminals.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
In cases of attempts to repair the motherboard 310431365664 310432868322, it is necessary to check the operability of the linear stabilizers and power converters of its microcircuits and, if possible, update the software (software). BGA chips can sometimes be diagnosed with local heating.
Board repair and replacement of FUSION120, H5TQ2G83BFR, H26M21001ECR, TAS5731P1 microcircuits are carried out 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 SUT-RE214AN 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
Attention to the owners! Attempts at self-repair of the PHILIPS 55PFL6007T TV are not recommended by the manufacturer and can lead to serious negative consequences!

PSU Advanced
The PLDK-P107B power supply module is made using the Power Factor Correction (PFC) scheme to eliminate multiple AC harmonics introduced into the power supply by the device. The PFC node is a Step-Up Converter based on the SCY99102BDR2G PWM controller, which evenly distributes high-frequency impulses of the charging current of the electrolytic capacitor of the rectifier filter of the mains voltage over a period of 50 Hz. The current of its charge in this case will already be determined not by its reactance (usually 10-30 ohms for the network frequency), but by the elements of the converter. As a result, a change in the amplitude of the pulses (envelope) of the consumed current of the converter will repeat the shape and phase of the input sinusoidal voltage. The availability of the increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.

To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the OZ9909TN PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 55PFL6007T TV are generated by the PLDK-P107B power module or its analogs using SCY99102BDR2G (PFC), L6599, FSL106MR microcircuits and MDF11N60 power switches.
