General recommendations for repairing TV LCD
Repair of the PHILIPS 32PFL5604H / 12 TV is advisable to start with a careful external examination. In this case, both external and internal components of the device should be inspected. Visible damage to elements can sometimes suggest directions for troubleshooting even before the necessary measurements are taken. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
Power Module Repair
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain chance that the PLHL T808A (LIPS32 FHD) supply 2722 171 00749 power supply module is defective and needs repair. Sometimes with similar manifestations a problem can only occur in the absence of processor power, which is typical for certain PHILIPS models and happens much less often. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module - rectifier diodes or power switch KHB 5DON50F.
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 cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the FSQ510 PWM controller microcircuit or broken resistors in its wiring.
In cases using a power module with an active KKM, troubleshooting is sometimes somewhat more complicated.
Inverter Repair
Sometimes the PHILIPS 32PFL5604H / 12 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).
In most cases, the diagnosis and repair of the PLHL T808A (LIPS32 FHD) 12lamp inverter is difficult due to the organization of protection, which turns it off in emergency cases to avoid fires during short circuits or open circuits 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.
When diagnosing with the protection off, special precautions must be taken, because there is a risk of failure of the power elements of the inverter. After the diagnosis, it is imperative to restore the protection circuits for the inverter to operate normally.
Repair Main Board
Diagnostics and repair of the motherboard SSB 3139 268 64854 is carried out by checking the performance of the stabilizers or power converters of the module chips. In some cases, a software update is required.
One of the most common typical defects on the TPM3.1E LA chassis motherboard is caused by the use of the G973-120 linear stabilizer (G973-120ADJF11U) to power the processor in standby mode (3.3 V). Perhaps the problem is caused by poorly selected thermal conditions, or poor quality microcircuit.
External manifestations: the TV does not turn on and no indicators light up, although the power supply is working. At the output of the G973-120, the voltage is 3.3V underestimated or missing. It is advisable to replace it with a more powerful 78R33 using heat sink.
Owners and users of the PHILIPS 32PFL5604H / 12 TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

The appearance of the power supply
Main features of the PHILIPS 32PFL5604 device:
Installed matrix (LCD panel) LC320WUE (SA) (A1).
The matrix control uses the Timing Controller (T-CON) LC320WUN.
To power the backlight, an inverter 715G3214-2 is used, it is controlled by the PWM controller UBA2071AT.
The necessary supply voltages for all nodes of the PHILIPS 32PFL5604 TV are generated by the 715G3214-2 power module, or its analogs using 1271A, S66961S, TNY277PN microcircuits.
MainBoard - the main board (motherboard) is a 715G3380-3 module, using MT8222TMMU chips and others.
The TAFT-S710D tuner provides TV reception and channel tuning.
