General repair guidelines for TV LCD LED
PHILIPS 47PFL3188T / 60, like other televisions, it is advisable to start repairing with a careful examination of the external and internal elements and modules. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
If the power supply module 715G6163-P0F-000-0020 996590008025 fails, the external manifestations may be different, for example, PHILIPS 47PFL3188T does not turn on at all and there is no indication of the indicator lights on the front panel. With the same symptoms, the stabilizer (converter) of the power supply to the control processor may be faulty. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin 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.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for 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.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when turned on, but the sound has other functions that work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the panel 99650008033 code 011). In such cases, the general power module is also subject to verification, in which the electrolytic capacitors of the rectifier filter supplying the LED driver should be checked.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
A break in the line of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
If the motherboard 715G6094-M0D-000-004K is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
If there is no reception of television channels, but the TV is working properly from external devices, first of all it is necessary to check the supply voltage of the tuner ST03CS-2-E 996590008033, which is usually within 30-33V, as well as other supply voltages on the tuner terminals.
Attention to users! Self-repair of a PHILIPS 47PFL3188T TV without the appropriate qualifications and experience can lead to its complete non-repairability!

Main features of the PHILIPS 47PFL3188T device:
Installed matrix (LED panel) TPT470H1-DUJFFE code 011 p / n: 99650008033.
The matrix control uses the Timing Controller (T-CON) 6870C-0444A.
The LED driver 715G6163-P0F-000-0020 is used to power the backlight LEDs, it is controlled by the PF7903BS PWM controller. As power elements of the LED driver, keys of the AOTF4126 type are used.
The necessary supply voltages for all nodes of the PHILIPS 47PFL3188T TV are generated by the 715G6163-P0F-000-0020 power module, or its analogs using SSC1S311 (PWM), LD7591T microcircuits and TK15A60U, STF24NM65N type power switches.
MainBoard - the main board (motherboard) is a module 715G6094-M0D-000-004K, using chips NT72567BG, K9F1G08U0D, 24C128, STA381BWTR and others.
