General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the PHILIPS 24PFL3507T / 60 TV, as well as the external elements of the housing. Often, based on certain external signs, it may be possible to draw certain conclusions about the reasons for the failure of certain elements of the circuit even before the necessary measurements are made, which will determine the further algorithm for troubleshooting and localizing the defect. In most cases, the repairman can guess the causes of the defect and possible consequences by 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.
Faults in the 715G5309-P01-W21-002S 996590000204 power supply module can be expressed in different ways, for example, the PHILIPS 24PFL3507T does not turn on at all and the control lights on its front panel do not light up and do not blink, and there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
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 controller chip are subject to verification, which it is desirable to verify by replacement.
Sometimes the PHILIPS 24PFL3507T TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the converter for the backlight LEDs of the panel 996590000202 code 161, or a break in the LED circuit is possible. In such cases, first of all, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the LED driver itself, including in the power supply unit (power supply unit).
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.
When trying to detect a break in the LED lines, it should be taken into account that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
When repairing an MB board, it is necessary to check its components K4B1G1646G-BCH9, S1084-33, AZ1117D-AD. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
Before replacing the tuner ENV57U04D8F, if there is no tuning to the channels, you must first check the supply voltage at its terminals, including the power supply of varicaps (30-33V).
Owners of the 24PFL3507T TV are recommended for repairing contact only qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!
