General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 32PFL5507T / 60, it is advisable to start with a careful external examination of internal and external elements. Often, based on certain external signs, it may be possible to draw certain conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing the defect. 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 the PHILIPS 32PFL5507T does not turn on, no control lights on the front panel light up and do not blink, therefore, there is a very high probability of a malfunction of the DPS-98EP A 2722 171 90579 power supply module. In some cases, only the processor power regulator may be faulty. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the strapping of the PWM controller microcircuit DDA010 H1208L2B (8), 2QS02G H1203 (8), which it is desirable to check by replacement, are subject to verification.
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 (LTA320HW02 panel power LED backlight converter code 395 932229091682). 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 detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
Repair or diagnostics of the motherboard 313929713562 UC 219.6 AL1.C should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
Attention to the owners! Attempts at self-repair of the PHILIPS 32PFL5507T 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 32PFL5507T device:
Installed matrix (LED-panel) LTA320HW02 code 395 p / n: 932229091682.
The matrix control uses the Timing Controller (T-CON) PH_120PSQBC4LV1.0.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the DDA015 PWM controller. As the power elements of the LED driver, keys of the D4NK60Z type are used.
The necessary supply voltages for all nodes of the PHILIPS 32PFL5507T TV are generated by the DPS-98EP power supply module or its analogs using DDA010 (Standby), ST9S101, ICE2QS02G (PWM) microcircuits.
MainBoard - the main board (motherboard) is a module 313929716961, using chips TAS5731, SPARTAN-6, RT8293AH (8) and others.
The SUT-RE214AN tuner provides TV reception and channel tuning.
