General repair guidelines for TV LCD LED
Diagnostics of malfunctions and repairs PHILIPS 42PFL6097T / 60, as well as other electronic devices, it is recommended to start with an external examination of the external and internal 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. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the 42PFL6097T does not turn on, does not respond to the remote control and buttons on the front panel, does not blink light bulbs and does not show any signs of operability, the power supply module DPS-119CP 272217190582 is probably faulty in this case. If it is working properly under such conditions, it is necessary to check the stabilizer (converter) of the processor power supply on the motherboard First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip can also cause a breakdown of the power switch of the converter.
If, when you turn on the TV, the image appears and immediately disappears, or is missing initially when you turn on, but the sound has other functions that work, there is a high probability of a malfunction of the LED driver (LC420EUF FEP1 panel LED backlight power converter code 322 932228895682). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
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 check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
Repair or diagnostics of the motherboard VU233.6 QFU2.1E LA 310432868342 should begin by checking the stabilizers or power converters of its chips. If necessary, you should update the software (software).
It should be remembered! Attempts to repair the PHILIPS 42PFL6097T TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

PSU Advanced
The 42PFL6097T / 60 TV is equipped with a DPS-119CP power supply 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 NCP1608B PWM controller does not allow the input rectifier filter's electrolytic capacitor to be connected to the network directly through open diodes when the charge current determines its reactance (about 15-30 ohms at a frequency of 50 Hz). 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.
