General recommendations for repairing TV LCD
Possible malfunctions
- The PHILIPS 47PFL3198T TV does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
Often in such cases, the 715G6163-P0F-000-0020 power module is faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of power switches (STF24NM65N, TK15A60U) of converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of diode breakdowns in the secondary circuits, the converter can operate in emergency short-circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually breaks.
Mos-Fet power switches, used in switching power supplies, sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode, or create an excess of the maximum permissible parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM controllers LD7591T (PFC), SSC1S311 (PWM), in the absence of visible damage or explicit short-circuit between the terminals, are checked by replacing with new, or obviously working.
- There is no image, there is sound, it responds to the remote control. Or the image may appear for a second when turned on and immediately disappears.
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or inverter. If all the electrolytic capacitors of the filter according to the power supply of the inverter are working, make sure that the lamps are working, then you need to check the converter keys and the secondary windings of the transformers.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the 715G6094-M0D-000-004K motherboard should be started by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software).
If the TV works normally from external devices, but does not tune into television channels, the ST03CS-2-E tuner may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
TV users and owners should remember that attempts to independently repair a PHILIPS 47PFL3198T TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

Main features of the PHILIPS 47PFL3198T device:
Installed matrix (LCD panel) TPT470H1-DUJFFE REV: S1A.
The matrix control uses the Timing Controller (T-CON) LC470DUE-SFR1.
To power the backlight, a converter is used, combined with a power supply, controlled by the F7903BS PWM controller. As power elements of the inverter, keys of the AOTF4126 type are used.
The necessary supply voltages for all nodes of the PHILIPS 47PFL3198T TV are generated by the 715G6163-P0F-000-0020 power supply module or its analogs using LD7591T (PFC), SSC1S311 (PWM) microcircuits and power switches of the STF24NM65N, TK15A60U type.
MainBoard - the main board (motherboard) is a module 715G6094-M0D-000-004K, using chips NT72567BG, K9F1G08U0D, 24C128, STA381BWTR and others.
The ST03CS-2-E tuner provides television reception and channel tuning.
