General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 32PHT4100 does not turn on at all. The control lights do not light or flash. On the remote control and the buttons on the control panel does not respond.
Often in such cases, the 715G6550-P03-000-002H power module is faulty. It is necessary to measure its output voltages and, if they are absent, check the power switches (TK6A65D) and rectifier diodes for the probability of short circuit in the converters.
In case of breakdowns in the secondary circuits, the converter can emergencyly operate in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may be PWM PF6003. It is checked only by replacement with a known good one.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the motherboard 715G6947-M01-000-004Y should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: NT72453; NAND Flash: MX30LF1G08AA-T1 1Gb; SOUND: AUDIO AD87588-LG48NAY and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
The malfunction of the ST42CS-2-E 394GNPALALL32L tuner is established after checking the software and all the supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
TV users and owners need to remember that attempts to self-repair a PHILIPS 32PHT4100 TV without the appropriate qualifications and the necessary experience can lead to serious negative consequences!

The appearance of the power supply
Key Features of the PHILIPS 32PHT4100:
Installed matrix (LED panel) TPT315B5-0TU3A.Q code: 003.
The matrix control uses the PANDA315 Timing Controller (T-CON).
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the PF7708AS PWM controller. As the power elements of the LED driver, keys of the type SM1A23NSUC-TRG are used.
The necessary supply voltages for all nodes of the PHILIPS 32PHT4100 TV are generated by the power module 715G6550-P03-000-002H, or its analogs using PF6003 microcircuits and TK6A65D type power switches.
MainBoard - the main board (motherboard) is a module 715G6947-M01-000-004Y, using CPU chips: NT72453; NAND Flash: MX30LF1G08AA-T1 1Gb; SOUND: AUDIO AD87588-LG48NAY and others.
The ST42CS-2-E 394GNPALALL32L tuner provides TV reception and channel tuning.
