General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular PHILIPS 32PFL3517T / 60, it is advisable to start with a careful external examination of internal and external elements. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. In most cases, the repairman can guess the causes of the defect and possible consequences from the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of the element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
If the 32PFL3517T 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.
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 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 32PFL3517T does not have an image, but there is sound, the backlight LEDs on the T320HVN01.5 XXXXG 996590001218 code 163 or their power converter may malfunction. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the lines and connectors.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
Repair or diagnostics of the motherboard 715G5155-M01-002-005K VerA 996590001306 should begin by checking the stabilizers or power converters of its microcircuits. If necessary, you should update the software (software).
Before changing the tuner ENV57U04D8F, if it is not possible to tune to television channels, make sure that there are supply voltages, including varicap power (30-33V), which must be measured on the corresponding tuner pins.
Remember! Attempts to self-repair by users of the PHILIPS 32PFL3517T TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!
