General repair guidelines for TV LCD LED
TV PHILIPS 47PFL7008S / 60, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Often, based on certain external signs, it may be possible to draw certain conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing the defect. Experienced repairmen are often aware of the causes of the defect and the possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
If the 47PFL7008S TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, only the regulator or power converter of the control processor may be faulty, which is typical for some PHILIPS models. 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.
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 B117H (8), FAN7930C (8), SSC9522C (18) 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 47PFL7008S 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 PFF1 panel code 430 932230114682. 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, connecting obviously known good diagnostics.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
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.
Repair or diagnostics of the YU 310.1 motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
In cases where there is no tuning to the local television channels, you should make sure that the varicaps supply voltage (30-33V) and other supply voltages are available at the terminals of the SUT-RE214AN 310432882021 tuner.
Attention! Users and owners of 47PFL7008S TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting self-repair in order to avoid negative consequences that could lead to complete non-serviceability of the device.

The appearance of MainBoard 310431366185 is shown in the figure below:310431366185
The weak point in the PHILIPS TV models assembled on the QFU1.2E LA chassis is the main board SSB (MainBoard), which usually refuses to work after two years of operation. Replacement required.
The cost of the board is quite high, which sometimes raises the question of the feasibility of repairs.
Despite the efforts of designers to complicate or exclude the possibility of repairing the board, there are still options for its restoration.
Attention to the masters !!! You should pay attention to the drop of compound from the bottom of the board. When trying to heat the board or reball of BGA chips, the compound must be completely removed. Otherwise, the paths will be closed, which will significantly complicate the further repair of the board.

PSU Advanced
According to the conditions of compliance with modern world standards for household switching power supplies, the FSP140-4FS01 module provides for the use of a Power Factor Correction unit. The PFC circuit is a flyback converter based on the FAN7930C 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.
