General repair guidelines for TV LCD LED
TV PHILIPS 32PFL3008T / 60, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal 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. 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.
In the absence of any signs of operability, when the PHILIPS 32PFL3008T 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 power supply module 996590004021 of the TV. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. When diagnosing and repairing the power supply, after replacing the swollen capacitors of the secondary rectifier filters (if any), you must first check the mains fuse. When it is broken, the power elements of transistors and rectifier bridge diodes should be checked for avalanche (thermal) breakdown.
Power switches in pulsed power supplies (SMPS) fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The cause may be a malfunction of the PWM controller chip, which can only be checked by replacing it with a new or obviously working one.
If the PHILIPS 32PFL3008T TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of panel 996590004018 code 196 is likely. It is also necessary to check the operability of the electrolytic capacitors of the filter of the secondary rectifiers of the power supply unit (PSU) for excessive ESR.
To check the health of the LEDs, as well as contact connections in the ruler circuit, the panel must be disassembled.
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.
Diagnosis and repair of the motherboard 996590004044 is carried out by checking the operability of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repair only to professionals with sufficient experience in the field of electronic equipment repair.
