General recommendations for repairing TV LCD
TV PHILIPS 32PFL9632, like other electronic devices, it is advisable to start repairing from inspection of external and internal elements. It often happens that some damage to elements or connections helps determine the direction of the troubleshooting. In some cases, faulty elements can be seen with the naked eye, for example, charred resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldered terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
Power Module Repair
If the PHILIPS 32PFL9632 does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a power module malfunction. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the N-FET converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
As a rule, the keys of flyback converters, which use an N-Fet field effect transistor on a separate radiator, or integrated with a PWM controller in a single chip, are reliable enough and rarely fail for no reason. The reasons for the breakdown of the key should be sought by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
In cases where the Power Factor Corrector (PFC) is used in the power supply, troubleshooting can be a bit more complicated.
Inverter Repair
If the PHILIPS 32PFL9632 does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the display backlight nodes is likely. The lamps or the power converter - inverter may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the inverter, and check the LCD lamps by connecting external and obviously serviceable for diagnosis to the connectors.
In most cases, the diagnosis and repair of the inverter is difficult due to the organization of protection, which turns it off in emergency cases to avoid fires during short circuits or breaks in high-voltage circuits and during depressurization of lamps. Often, repairmen block the protection circuits in order to make the necessary measurements at the control points of the inverter to identify the causes of the defect.
In such cases, special care should be taken during diagnostics, and after completion of all repair work it is necessary to restore the circuit and the inverter protection for further safe operation of the TV.
Once again, remind users! Attempts to independently repair the PHILIPS 32PFL9632 TV without the appropriate qualifications and experience can lead to its complete non-repairability!
