General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 47PFL4007T / 60, it is advisable to start with a careful external examination of internal and external elements. Many visible changes in the state of the elements make it possible to determine the further direction of troubleshooting and localization of the defect. 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.
If PHILIPS 47PFL4007T does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a failure of the 715G5246-P01-00-002H 996510051156 power supply module. In some cases, only the processor power regulator may be faulty. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as a large electrolytic capacitor of the filter of the rectifier network.
The reasons for the breakdown of the power switch in pulsed power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or broken resistors in its bundle.
If the PHILIPS 47PFL4007T does not have an image, but there is sound, the backlight LEDs of the LC470EUE SEM2 code 349 932228892682 or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
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.
When trying to detect a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
Repair of the motherboard YU 239.7 AI1.C 313929713444 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.
If there is no reception of television channels, but the TV works properly from external devices, first of all it is necessary to check the voltage of the varicaps of the tuner BUT-RE214AN, which is usually within 30-33V, as well as other supply voltages at the terminals of the tuner.
Remember! Attempts to self-repair by users of the PHILIPS 47PFL4007T TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

PSU Advanced
The 47PFL4007T / 60 model uses a 715G5246-P01-00-002H power supply unit using the PFC (Power Factor Correction) node - an active filter of higher harmonics of the current consumption. In fact, it is a boost converter based on the R2A20113 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.
