General repair guidelines for TV LCD LED
Repair of the PHILIPS 32PFL4007T / 60 TV should begin with a careful external inspection of all its components and modules. 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.
Faults in the 715G5194-P02-W20-002H power module for AUO + LED DRIVE can be expressed in different ways, for example, the PHILIPS 32PFL4007T does not turn on at all and the control lights on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, PF7700S PWM controller (8), PF7900S, LD7523GS, A6069H, which can only be checked by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the PHILIPS 32PFL4007T TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the T320HVN01.5 AUO code 408, LC320EUE SEM1 code 391 932228889682 is likely to occur. It is also necessary to check the operability of the electrolytic capacitors of the filter of the secondary rectifiers of the power supply unit (power supply unit) for excessive ESR
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.
It should be remembered that it is not possible to determine the open circuit in the LED lines without disassembling the panels with a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
Before changing the SUT-RE214AN tuner, if it is not possible to tune to television channels, make sure that there are supply voltages, including varicap power (30-33V), which must be measured on the corresponding tuner pins.
Once again, remind users! Attempts to self-repair a PHILIPS 32PFL4007T TV without the appropriate qualifications and experience can lead to its complete non-repairability!
