PHILIPS 47PFL9732D
General recommendations for repairing TV LCD
It is advisable to start repairing all electronic devices, including the PHILIPS TV, based on the Q528.1E LA chassis, with an external examination of its external and internal elements. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. If ring cracks are detected in the soldered terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the PHILIPS 47PFL9732D does not turn on, no control lights on the front panel will light or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
It should be remembered that the keys used in switching power supplies (SMPS) rarely fail without themselves, without any reasons that must be sought by checking other elements of the circuit. 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, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but there is sound and other functions work, there is a high probability of a malfunction of the inverter (power converter for the backlight). In such cases, the lamps, the inverter and the common power module are subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the inverter should be checked. When disabling the inverter protection (to enable diagnostics), special care must be taken in view of the risk of failure of the power elements. After completing all repair work, it is imperative to restore the protection circuits for full and safe further operation of the TV by the user.
Remember! Attempts to self-repair by users of the PHILIPS 47PFL9732D TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!
