General repair guidelines for TV LCD LED
PHILIPS 40PFL3107H / 60, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Using visible changes in the state of components, it is usually possible to determine the further direction of troubleshooting and localization of the defect before the necessary measurements are taken. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
If the power supply module 715G5246-P03-000-002H malfunctions, the external manifestations may be different, for example, PHILIPS 40PFL3107H 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 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 elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the A6069H PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
In cases where the PHILIPS 40PFL3107H TV has lost an image, and the sound is there and all the other functions are functional, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the LTA400HM23 panel). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It is necessary to disassemble the panel and check the LEDs themselves, the soldering of their conclusions, as well as the reliability of the connections in the connectors and the soldering of the conclusions of the connectors.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
Repair of the 715G5155-M02-002-005K VerA motherboard should begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
If the TV works normally from external devices, but does not tune into television channels, the tuner ENV57U09D5F may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals, as well as the power supply of varicaps (30-33V).
We recommend the owners of the 40PFL3107H TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!
Typical problems associated with the lack of a PHILIPS 40PFL3107H / 60 image occur due to Samsung's problematic LTA400HM23 LED panel.
External manifestations: no image, sometimes appears, but disappears again.
In most of these cases, panel repair is possible and widely practiced by repairmen. Faulty LEDs must be replaced and duplicated contacts duplicated by conductors. For prevention purposes, it is advisable to duplicate all contact connections between the LED strips.

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the 715G5246-P03-000-002H module provides for the use of the Power Factor Correction unit. The PFC circuit is a flyback converter based on the R2A20113 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.
