General recommendations for repairing TV LCD
Repair of the PHILIPS 32PFL9603D / 10 TV should begin with a careful external inspection of all its components and modules. Also subject to inspection are body elements, functional control buttons, screen, cords and connectors. Specific external damage to the elements can sometimes prompt further actions to determine the malfunction of the TV and localize the defect before starting the necessary measurements and taking waveforms. 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.
Power Module Repair
In the case when the 32PFL9603D / 10 does not turn on, does not respond to the remote control and the front panel buttons, does not blink bulbs and does not show any signs of operability, most likely the DPS-230MPA power supply module is faulty in this case. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken in the power supply, in most cases a breakdown of the power switch 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 remembered that in the practice of repair, usually the power keys of N-Fet converters 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 power module uses an active KKM circuit (power factor control), troubleshooting is somewhat more complicated.
Inverter Repair
Sometimes the PHILIPS 32PFL9603D / 10 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 backlight converter, or of the lamps themselves, which can be checked by replacement. In such cases, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the inverter itself, including the power supply unit (power supply unit).
Often, attempts to repair the RUNTKA332WJZZ inverter (75) are hampered by the fact that the diagnosis of the malfunction is complicated by the operation of its protection, which is designed to turn off the inverter in emergency conditions - when the lamps are depressurized, breaks or short circuits in high-voltage connections and other emergency situations. Lock protection to localize the defect is popular among repairmen.
All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
Attention to the owners! Attempts at self-repair of the PHILIPS 32PFL9603D / 10 TV are not recommended by the manufacturer and can lead to serious negative consequences!
