General repair guidelines for TV LCD LED
PHILIPS 42PFL6057T / 60, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. 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.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when it is turned on, there is a certain chance that the DPS-119CP 272217190605 power supply module is defective and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of processor power, which is typical for certain PHILIPS models. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options *.
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 DDA010, SCY99102BDR2G, L6599, FSL106MR can also cause a breakdown of the power switch of the converter.
If the PHILIPS 42PFL6057T does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the backlight circuits of the LC420EUF FC P1 panel is likely. The LEDs or the power converter - LED driver may be faulty. 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.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips with new ones or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
In cases where there is no tuning to the local television channels, you should make sure that there is a varicap supply voltage (30-33V) and other supply voltages at the terminals of the SUT-RE214AN tuner.
Attention to users! Self-repair of a PHILIPS 42PFL6057T TV without the appropriate qualifications and experience can lead to its complete non-repairability!

PSU Advanced
The 42PFL6057T / 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 SCY99102BDR2G 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.
