General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 32PFL6007T / 12, it is advisable to start with a careful external examination of internal and external elements. Often by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
In the case when the 32PFL6007T does not turn on, does not respond to the remote control and buttons on the front panel, does not blink light bulbs and does not show any signs of operability, the PLDD-P109A HR-PSL3237 3 power supply module is probably defective in this case. it is necessary to check the power supply stabilizer (converter) of the processor on the motherboard 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 secondary rectifiers atelier. 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.
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 the PHILIPS 32PFL6007T has no image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the LC320EUF FEP1 code 423, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
To check the health of the LEDs, as well as contact connections in the ruler circuit, it is necessary to disassemble the panel.
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.
Repair of the motherboard UC 223.4 AI1.3 310432868323 must 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.
Attention to the owners! Attempts at self-repair of the PHILIPS 32PFL6007T TV are not recommended by the manufacturer and can lead to serious negative consequences!
