PHILIPS 32PHS4032
General recommendations for TV LCD LED repair
Possible manifestations of defects
- TV PHILIPS 32PHS4032 does not turn on and does not show any signs of turning on, does not respond to control buttons and to the remote control.
In such cases, you should start looking for a fault in the 715G7734-P02-005-002H power supply circuits. Its output voltages should be measured and, in their absence, the serviceability of the power switches (TK6A65D) and rectifier diodes in the converters should be checked for possible breakdown.
In case of breakdowns of semiconductors in the secondary circuits, the converter can usually operate in an emergency in the short-circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse often breaks.
Breakdown of Mos-Fet switches used in switching power supplies is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency setting or damper circuits, as well as in negative feedback stabilization. PWM microcircuits (PWM) PF6005A (PWM SOT23-6) are usually checked by replacing them with new ones, or known to be working properly.
- There is no picture, but there is sound and all other TV functions are working. The image sometimes appears for a second immediately after switching on and disappears.
Often, in such cases, there is no backlighting of the LED panel. The reason for this may be an open circuit in the LED circuit, or a problem in stabilizing their power supply.
READ HOW TO REPAIR THE TV LED BACKLIGHT --------------> HERE.
It is impossible to check the LED bars for a break without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally a current source. Having disassembled the panel, it is necessary to check each LED separately. Chinese multimeters tend to light one 3-volt LED in the forward direction. In the case of using dual 6-volt LEDs, the PN junction of its protective zener diode can serve as an indicator of serviceability. In faulty LEDs, the zener diode will either be cut off, or pierced in the K / Z.
- The indicator on the front panel blinks, the TV does not turn on in operating mode, does not respond to the remote control.
Repair or diagnostics of the 715G8659-M01-000-004Y motherboard should begin with checking the stabilizers and power converters required to power the microcircuits and matrix. If necessary, you should update or replace the software (software). If it is not possible to replace the MB (SSB) board, you need to check the health of its elements - CPU: NT72461, NAND: W29N01HVSINF, AUDIO: TAS5753MD. Defective components must be replaced.
If you suspect a malfunction of the TDSY-G430D tuner, first of all, you need to make sure the software is correct, as well as the presence of the required supply voltage levels and pulses of data exchange with the processor via the I2C bus on the corresponding tuner pins.
Attention to users! Self-repair of the PHILIPS 32PHS4032 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

External view of the power supply
The main features of the PHILIPS 32PHS4032 device:
Installed matrix (LED panel) TPT315B5-AN10.S.
A converter combined with a power supply is used to power the backlight LEDs and is controlled by a PF7708BS PWM controller. The keys of the MTBA5N10J3 type are used as power elements of the LED driver.
The formation of the necessary supply voltages for all nodes of the PHILIPS 32PHS4032 TV is carried out by the 715G7734-P02-005-002H power module, or its analogs using PF6005A (PWM SOT23-6) microcircuits and TK6A65D power switches.
MainBoard - the main board (motherboard) is a 715G8659-M01-000-004Y module, using CPU chips: NT72461, NAND: W29N01HVSINF, AUDIO: TAS5753MD and others.
The TDSY-G430D tuner provides reception of television programs and tuning to channels.
PWM SMPS in SOT-23-6, SOT-26, TSOP-6 packages
In
the circuitry of modern switching power supplies (SMPS), PWM
controllers made in small-sized planar packages with six terminals have
gained wide popularity. The enclosure type designation can be SOT-23-6,
SOT-23-6L, SOT-26, TSOP-6, SSOT-6. The appearance and arrangement of the
pins are shown in the figure below. In this case, the code marking
LD7530A is shown on the left fragment of the picture.
Pin assignment:
1 - GND. (Common wire).
2
- FB. (FeedBack - Feedback). Input for controlling the duration of
pulses with a signal from the output voltage. Sometimes it can be
labeled COMP (input comparator).
3 - RI / RT / CT / COMP / NC -
Depending on the type of microcircuit, it can be used for a
frequency-setting RC circuit (RI / RT / CT), or for organizing
protection, as an input of a PWM trip comparator at a threshold value at
its input, specified in the document. In some types of microcircuits,
this input may not be used in any way (NC - No Connect).
4 - SENSE, otherwise CS (Current Sense) - Input from the current sensor at the source of the key.
5 - VCC - Input voltage supply and start of the microcircuit.
6 - OUT (GATE) - Output for controlling the gate (Gate) of the key.
Functionally,
these regulators work on the principle of the previously popular xx384x
PWM microcircuits, which have proven themselves well in terms of
reliability and stability.
Some difficulties often arise when
replacing or choosing an analog for such PWM regulators due to the use
of code markings in the designation of the type of microcircuits. The
situation is complicated by a large number of component manufacturers
who do not always provide documentation to the mass access, just as not
all manufacturers of finished devices supply repair service centers with
diagrams, so repairmen often have to study real circuit solutions by
installed components and wiring connections directly on the board.
In
practice, PWM microcircuits and the marking code EAxxx and Eaxxx are
often found. Official documentation for them was not found in the public
domain, but discussions on the forums and pieces of pictures from PDF
from System General, which publishes them as SG6848T and SG6848T2, have
survived. The drawing is here placed left .
For the attention of the masters, here below are PDF datasheet tables
compiled from information available on the Internet and PDF documents
for the selection of analogues types when replacing the most common
six-legged planar PWM with pinout pins: pin1 - GND, pin2 - FB (COMP),
pin4 - Sense, pin5 - Vcc, pin6 - OUT ...
Their main difference is the application and purpose of pin 3.

PWM controllers that use pin 3 differently.
When
using the following PWM (PWM controllers), you should pay attention to
pin 3, which can be used to organize protection - thermal or from
overvoltage of the input voltage.
The frequency can be fixed at 65kHz, or set by the value of the capacitor at pin 3.
When replacing any microcircuits with analogs, carefully study the documentation. PDF files are packed in a RAR archive.

Attention! The panel TPT315B5-AN10.S of the PHILIPS 32PHS4032 LED TV is an expensive and unreliable element.
Avoid any impacts on the glass and pressure on the screen surface to avoid damage to the LED panel!
It is also unsafe for liquid to spill onto the screen. Sometimes one drop is enough if it drips down the glass onto the cables to make the TV unrepairable.
