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 47PFL6907T / 12 TV, as well as the external elements of the case. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. Ring cracks in the soldering of the leads of the heating elements, swollen electrolytic capacitors, a charred paint layer on the resistors - all this for the repairman can be a significant clue in the assumptions about the causes and consequences of the malfunction.
If the PHILIPS 47PFL6907T does not turn on, no control lights on the front panel are on or blinking, therefore, there is a very high probability of a failure of the FSP145-4F501 power module. In some cases, only the processor power regulator may be faulty. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
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 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.
If the PHILIPS 47PFL6907T does not have an image, but there is sound and the TV is controlled by the remote control, there may be a malfunction in the backlight circuits of the LC470EUF PEF1 code 414. The LEDs or the power converter - LED driver may be malfunctioning. 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 using a current source.
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.
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.
Repair or diagnostics of the SSB motherboard should begin by checking the stabilizers or power converters of its chips. If necessary, you should update the software (software).
We recommend the owners of the 47PFL6907T TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

PSU Advanced
The power module FSP145-4FS01 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 FAN7930C PWM controller, which evenly distributes high-frequency pulses 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.

Main features of the PHILIPS 47PFL6907T device:
Installed matrix (LED-panel) LC470EUF PEF1 code 414.
The matrix control uses the Timing Controller (T-CON) T-CON.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the BD9479FV PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 47PFL6907T TV are generated by the FSP145-4FS01 power supply module or its analogs using the FSB117H (Standby 8pin), FAN7930C (PFC), SSC9522S (PWM resonant) microcircuits.
