General repair guidelines for TV LCD LED
Repair of the PHILIPS 32PFL3018T / 60 TV should begin with a careful external examination of all its components and modules. Using visible changes in the state of components, it is usually possible to determine the further direction of troubleshooting and localization of the defect before the necessary measurements are taken. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
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 turned on, there is a certain chance that the 715G5793-P02-000-002H DSPJ08001 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.
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 chip are subject to verification, which it is desirable to verify by replacement.
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 (power converter for the backlight LEDs of the DUNTK5004ZZ panel, RUNTK5003 code 196). 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.
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
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.
Repair of the 715G5675-M01-000-005K VerA motherboard should begin with the diagnosis and verification of all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
Before changing the TDSY-G230D 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.
It should be remembered! Attempts to repair the PHILIPS 32PFL3018T 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!

Main features of the PHILIPS 32PFL3018T device:
Installed matrix (LED-panel) DUNTK5004ZZ RUNTK5003 code 196.
To power the backlight LEDs, a converter is used, combined with the power supply, it is controlled by the PF7900S, PF7700A PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 32PFL3018T TV are generated by the 715G5793-P02-000-002H power supply module or its analogs using PF6200 microcircuits (PWM flyback).
MainBoard - the main board (motherboard) is a module 715G5675-M01-000-005K, using microchips MTK5580CPOI, TC58NVG1S3ETAI0, CAT24C128WI, STA381BWTR and others.
The TDSY-G230D tuner provides TV reception and channel tuning.
