General repair guidelines for TV LCD LED
In the absence of any signs of operability, when the PHILIPS 32PFL5606H does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the TV power supply module 715G4738-P1B-H20-002U. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off 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.
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 SSC9512S (18pin), TNY274PN (7), CAP004D6 (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 32PFL5606H TV does not have an image, but there is sound, a malfunction in the backlight circuits of the LED panel LC320EUG (SD) (N6) is likely.
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the rations of their terminals, as well as the reliability of the connections in the connectors and rations of the terminals.
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.
On the motherboard 715G4722-M1C-000-005B, in the event of a malfunction, you should first check the performance of all the stabilizers and power converters of the microcircuits, and also, if necessary, update the software (software).
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its chips SI5403DC-T1-GE3, H5PS1G63EFR-G7C, AT24C02C, MT5135AE / A, STA339BWTR and other possible faulty components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
If you suspect a malfunction of the ENV57U03D5F tuner, first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
Attention to the owners! Attempts at self-repair of the PHILIPS 32PFL5606H TV are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the power supply
Main features of the PHILIPS 32PFL5606H device:
Installed matrix (LED-panel) LC320EUG (SD) (N6).
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the OZ9908AGN PWM controller (28pin). The transformer 80GL32P-73-H HI-POT is installed in the LED driver converter. As the power elements of the LED driver, keys of the type K7A50D, 2907A are used.
The necessary supply voltages for all nodes of the PHILIPS 32PFL5606H TV are generated by the 715G4738-P1B-H20-002U power module, or its analogs using SSC9512S (18pin), TNY274PN (7), CAP004DG (X-Capacitor Discharge IC) microcircuits.
