General repair guidelines for TV LCD LED
Repair of the PHILIPS 32PFL6606H / 60 TV should begin with a careful external examination of all its components and modules. 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. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
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 it is turned on, there is a certain chance that the DSP-93BP 2722 171 171 90337 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. 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.
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 regulator chip FSQ510 (7), FAN7621B (16), which it is desirable to check by replacement, are subject to verification.
If the PHILIPS 32PFL6606H TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the LK315D3LA63 code 327 panel 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 (power supply unit) for excessive ESR.
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 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.
Diagnostics and repair of the motherboard PL5.6 3139 297 11911 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.
Owners and users of the PHILIPS 32PFL6606H TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
