General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 32PFL3517 / 60, 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. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
If the 32PFL3517 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, only the regulator or power converter of the control processor may be faulty, which is typical for some PHILIPS models. 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 in the primary circuit.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip can also cause a breakdown of the power switch of the converter.
If the PHILIPS 32PFL3517 does not have an image but has sound, the backlight LEDs of the LC320EUE (SE) (M1) code 156 932228889682 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.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
Diagnostics and repair of the motherboard 715G5155-M01-002-005X (verA) 996590001036 is carried out by checking the performance of the stabilizers or power converters of the module chips. In some cases, a software update is required.
Once again, remind users! Attempts to self-repair a PHILIPS 32PFL3517 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
