General repair guidelines for TV LCD LED
Repair of all electronic devices, including the PHILIPS 40PFL7007T / 12 TV, it is advisable to start with an external examination of its external and internal elements. 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. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In cases when the PHILIPS 40PFL7007T TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the power supply module FSP163-4FS01 SK 227.5 is most likely faulty 015.D or there is no processor power on the motherboard (a typical defect of some PHILIPS TVs). It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, PWM controller B127H (8), which can be checked only by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the PHILIPS 40PFL7007T 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 LTA400HL15 003. 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.
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.
A break in the line of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
Repair of the motherboard 310432869191 UC 230.3 AI1.C must 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.
Attention to the owners! Attempts at self-repair of the PHILIPS 40PFL7007T TV are not recommended by the manufacturer and can lead to serious negative consequences!

PSU Advanced
The model 40PFL7007T / 12 uses the FSP163-4FS01 power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a boost converter based on the FAN7930C PWM controller, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.

Installed matrix (LED panel) LTA400HL15 code 003.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by a PWM controller 0Z9909TN x 2, LM358G.
The necessary supply voltages for all nodes of the PHILIPS 40PFL7007T TV are generated by the FSP163-4FS01 power supply module or its analogs using the FSB127H microcircuits (3.3V Standby. 0V in slave mode), FAN7930C (PFC), SSC9522S (PWM resonant).
