General repair guidelines for TV LCD LED
TV PHILIPS 42PFL6008S / 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. In some cases, faulty elements can be seen with the naked eye, for example, charred resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
In the case when the 42PFL6008S does not turn on, does not respond to the remote control and the front panel buttons, does not blink light bulbs and does not show any signs of operability, the power supply module FSP140-4FS01 272217190775 is probably faulty in this case. If it is working properly under such conditions, it is necessary to check the stabilizer processor converter on the motherboard In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it breaks, it is necessary to first It’s your turn to check all the power semiconductor elements of the primary circuit — diodes and transistors — for the possibility of an avalanche or 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 the semiconductor elements of the strapping of the BCYAO B117H PWM controller microcircuit are subject to verification, which it is desirable to verify by replacement.
Sometimes the PHILIPS 42PFL6008S TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the LC420EUF PF F1 panel backlight LED converter, or an open circuit in the LED circuit is possible. In such cases, first of all, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the LED driver itself, including in the power supply unit (power supply unit).
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
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.
We recommend the owners of the 42PFL6008S TV for repair only to qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

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
The FSP140-4FS01 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 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 an increased voltage (about + 380V) in the operating mode on the capacitor of the line filter indicates the serviceability of the PFC node.
The appearance of the power supply
Key Features of PHILIPS 42PFL6008S:
Installed matrix (LED-panel) LC420EUF (PF) (F1).
The matrix control uses the Timing Controller (T-CON) 6870C-0450A.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a BD9479FV PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 42PFL6008S TV are generated by the FSP140-4FS01 power supply module or its analogs using SSC9522S (PWM 18pin), FAN7930C (PFC), FSB117HNY (B117H-Standby) microcircuits.
MainBoard - the main board (motherboard) is a module 310431366185, using chips FUSION120, H5TQ2G63BFR, H5TQ2G83BFR and others.
The SUT-RE214AN tuner provides TV reception and channel tuning.
