General advice about LCD LED TV repair
Possible problems
-
PHILIPS 43PUS6401 TV does not turn on. There is no indication of any
functionality. No LEDs on the front panel are not blinking or on, the TV
does not respond.
In cases like this, the problem should start
with the power supply circuits 715G7350-P01-000-002S. It is necessary to
measure in its secondary circuits output voltages, and in case of their
complete absence, you should check the serviceability of the power
switches (TK20A60W) and the rectifier diodes for possible breakdown
(short circuit).
If there is a breakdown in the secondary circuits,
the inverter may be short-circuited, and if there is a short in the
primary circuit elements, the mains fuse usually blows.
Breakdown of
power switches (MosFet) in pulsed sources, sometimes caused by faults in
other circuit elements, for example, in the circuits that feed the PWM
controller, frequency-retaining or damping circuits, as well as in the
negative feedback (negative feedback) stabilization circuits. PWM
regulators (PWM) LD7591T, SSC3S121A, if do not have visible damage to
the housing and outright short circuit between the pins, usually checked
by replacing.
- No picture, but there is sound and the remote responds. Or the image appears at power on and immediately disappears.
Often
in such cases there is no backlight of the LED panel. The reason can be
found in the malfunction LEDs, in violation of the contact connections
of the LED strips GJ-2K16-430-D512-V4, or in their power supply
(LED-driver).
It is impossible to check the LED strips for breakage
without disassembling the panel with a multimeter or a tester. For this
purpose, you need to open all the series-connected PN-junctions and will
need a voltage of about tens of volts, and ideally - a current source.
Having disassembled the panel, it is necessary to check each LED
separately. Chinese multimeters tend to light up a single 3 volt LED
slightly in the forward direction. In the case of twin 6 volt LEDs, the
PN junction of its safety regulator may be a good indicator. In faulty
LEDs, the regulator will either be broken or broken in short circuit.
If
PHILIPS 43PUS6401 has no picture, but there is sound, often the
backlight of the display TPT430U3-EQYSHM.G. Moreover, in LED-TVs usually
fail LEDs inside the panel, less often the LED-driver.
In such cases you can see a faintly visible image when external light hits the screen.
To
replace the LEDs requires disassembly of the LCD-panel
TPT430U3-EQYSHM.G - the process requiring a master of experience and
expertise. We do not recommend to perform such works by yourself to
owners of TV sets and craftsmen who have no experience in LCD panel
repair.
READ HOW TO REPAIR THE TV LED BACKLIGHT --------------> HERE.
If
there is no image, but backlighting works - the screen becomes slightly
lighter when the TV is switched on, and in the open TV you can see the
light through the holes in the body of the panel.
In this case the
panel may be defective - damage to the strips, cables, for example, as a
consequence of moisture after an unsuccessful washing of the screen,
the T-CON board (Timing Controller) may be defective. But often the
MainBoard 715G7776-M0F-B01-005K is also faulty, and software failure is
also possible.
Then first it is necessary to check the panel power
supply voltage, fuses on the T-CON board, as well as the supply and
reference voltages of the column and line drivers - VGH, VGL, Vcom.
If
these measurements are within normal limits, you need to trace by
oscilloscope the LVDS signals from MainBoard 715G7776-M0F-B01-005K, as
well as synchronizing signals to driver stubs.
Filled or badly
washed LED TV screens can be restored in about half of the cases,
usually, if there are not significant damages in the hinges and slats of
the panel.
- The TV does not turn on, the remote control does not respond. Indicator is blinking or in standby mode.
Repair
or diagnostic of the motherboard 715G7776-M0F-B01-005K should begin
with checking the stabilizers and power converters needed to power the
chips and matrix. If necessary, update or replace the software
(firmware).
To owners of TV set 43PUS6401 we recommend to
apply only to qualified specialists with necessary experience for
repair! Attempting to repair it yourself without proper knowledge and
skills can lead to irreversible negative consequences!

Reduce
backlight current from 190 mA to 140 mA - removed resistors R8625,
R8633 in the LED driver current sensors on the 715G7350-P01-000-002S
board.

General information.
To reduce the backlight current in TVs with the 715G7350-P01-000-002S power supply, the board has two assemblies of resistors (current sensors) for the two channels, R8624, R8625, R8626, R8627 and R8631, R8632, R8633, R8634. You can remove one or two resistors in each assembly for both channels equally.

715G7776-M0F-B01-005K
The main features of the PHILIPS 43PUS6401 device:
A matrix (LED panel) TPT430U3-EQYSHM.G is installed.
Timing Controller (T-CON) 6870C-0552A is used to control the matrix.
The converter combined with a power supply is used to power the LED backlight and is controlled by a PWM controller PF6002AS. As the power elements of LED-driver are used switches type TK11A65D.
Required supply voltages for all PHILIPS 43PUS6401 TV assemblies are generated by power supply module 715G7350-P01-000-002S or its analogues using LD7591T, SSC3S121A chips and TK20A60W type power keys.
MainBoard - the main board (motherboard) is a module 715G7776-M0F-B01-005K, with the use of chips CPU, eMMC, DRAM, AUDIO, DC/DC and others.
The TDSY-G430D tuner provides TV program reception and channel tuning.

Warning. The panel TPT430U3-EQYSHM.G LED-TV PHILIPS 43PUS6401 is an expensive and unreliable part of the TV.
Do not allow any impacts on the glass and pressure on the surface of the screen to avoid damage to the LED-panel!
Also it is not safe to get liquid on the screen. Sometimes one drop is enough if it drips down the glass onto the cables and the TV becomes unrepairable.
