General repair guidelines for TV LCD LED
Repair of all electronic devices, including the PHILIPS 32PFL6605H / 60 TV, it is advisable to start with an external examination of its 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. 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.
If the power supply module DPS-93BP 3.3 V.12V fails. 24V, external manifestations may be different, for example, PHILIPS 32PFL6605H does not turn on at all and there is no indication of indicator lights on the front panel. With the same symptoms, the stabilizer (converter) of the power supply to the control processor 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 1A31CP.1A35CN in the primary circuit.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the FSQ510 (7), FAN7621B (16) PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If the PHILIPS 32PFL6605H does not have an image but there is sound, the backlight LEDs of the LC320EUH (SC) (A6) panel code 298 (code 286), or their power converter may be malfunctioning. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
It is impossible to check the LED line for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source.
If the motherboard 3104 328 64493 is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - LG TL2429MC. TPA312302 Ounch, DC-DC RT8250 (8). Max 17113E (10x10), 4952 (8), 4778 (8), ST1S10PH ST1S10B (8) for new or obviously working. In cases where BGA technologies are used, defects are usually localized by the heating method.
If the TV works normally from external devices, but does not tune to television channels, the tuner may have a failure 3104 328 64493. In such cases, you should first make sure that there are power supply voltages on its respective terminals, as well as power supply to varicaps (30-33V).
Remember! Attempts to self-repair by users of the PHILIPS 32PFL6605H TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!
