General recommendations for repairing TV LCD
Repair of the PHILIPS 23PFL5322 / 58 TV is advisable to start with a careful external examination. In this case, both external and internal components of the device should be inspected. Specific external damage to the elements can sometimes prompt further actions to determine the malfunction of the TV and localize the defect before the necessary measurements and waveforms are taken. Electrolytic capacitors of filters with a swollen casing, as well as ring cracks formed in the soldered leads of heating elements, or a layer of coal on burnt resistors sometimes tell the repairman the causes of the malfunction and possible consequences.
In the absence of any signs of operability, when the PHILIPS 23PFL5322 / 58 does not turn on and does not signal anything with the control lights on the panel, the power supply module DAC-12M058 BF, PLCD190P3 is most likely to be faulty. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all power semiconductor elements of the converter and the rectifier diode bridge of the network, as well as the large electrolytic capacitor of the filter of the network rectifier and the key transistor 2761I P10NK60.
The reasons for the breakdown of the power switch of the flyback converter of the power module can be different, for example, a malfunction of semiconductor elements or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip L6562D (8n) SG5841JSZ (8) or breakage of resistors in its bundle .
If the power module uses an active KKM circuit (power factor control), troubleshooting is somewhat more complicated.
Sometimes the PHILIPS 23PFL5322 / 58 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 electrolytic capacitors of the filter according to the power supply of the inverter itself, including the power supply unit (power supply unit).
The operation of the power circuits of the inverter and the backlight in the normal mode are controlled by special protection, which is organized for fire safety, for example, to disconnect during short circuits or breaks in high-voltage connections or when the lamps are depressurized. This protection makes it difficult to diagnose and repair the inverter.
In such cases, the risk of failure of the power elements of the inverter is most likely, and special care is required during work, and after their completion, it is necessary to restore the protection circuit for further safe operation of the TV by the owner in normal mode.
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). If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - TDA9886T, SVP CX32 7332 LF, TDA8932T. Defective components should be replaced.
Attention to the owners! Attempts at self-repair of the PHILIPS 23PFL5322 / 58 TV are not recommended by the manufacturer and can lead to serious negative consequences!

PSU Advanced
The 23PFL5322 / 58 model uses a PLCD190P3 power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a boost converter based on the L6562D PWM controller, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.
