General repair guidelines for TV LCD LED
PHILIPS 47PFL6057T / 60, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and determine the direction of further troubleshooting even before the necessary measurements are taken. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
If PHILIPS 47PFL6057T does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a malfunction of the DPS-130QP A B 272217190584 power supply module (DPS-119CP A). In some cases, only the processor power regulator may be faulty. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
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 DDA010 (8), 1608B (8), 2QS02Q Q1211 (8) 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 47PFL6057T TV does not have an image, but there is sound, it is likely that there is a malfunction in the LED backlight circuits of the TFT-LCD LC470EUF-FEP1 (LGPH) B 932228896682 code 323. It is also necessary to check the operability of the electrolytic capacitors of the BP secondary filter (power supply) for the subject overstated ESR.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
Repair of the motherboard AS 2K12 FU EU6 EX T2 2D-3D AL RF 310432868341, 310432868342 should 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.
Once again, remind users! Attempts to self-repair a PHILIPS 47PFL6057T TV without the appropriate qualifications and experience can lead to its complete non-repairability!

PSU Advanced
The 47PFL6057T / 60 TV is equipped with a DPS-130QP power module using the PFC (Power Factor Correction) scheme acting as an active filter to eliminate the higher harmonic components of the current consumption. The boost converter based on the 1608B PWM controller does not allow the input rectifier filter's electrolytic capacitor to be connected to the network directly through open diodes when the reactance (about 15-30 ohms at a frequency of 50 Hz) determines the charge current. As a result of the conversion, the charging current of the capacitor will be determined in such a way that the envelope of the high-frequency pulses of the input current will repeat the phase and shape of the sine wave of the input voltage. The health check of the PFC unit is carried out by measuring the DC voltage on the capacitor of the rectifier network. In operating mode, it should be around 380V, in standby approximately 300V.
