General repair guidelines for TV LCD LED
Possible manifestations of defects
- The PHILIPS 32PHT4509 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.
In such cases, the fault should be sought first in the 715G6197-P01-003-002H power supply module. It is necessary to measure its output voltages, and if they are absent, check the operability of the power switches (STD432S, 2SK3569) of the converters and rectifier diodes for a short circuit probability.
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. In the case of PF6200S, FAN7530 (PFC), ICE3BR1765J, FSFR1800US PWM controllers, in the absence of visible damage or open faults between the terminals, they are checked by replacing them with new ones, or those that are obviously working.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
In some of these cases, the malfunction is caused by a lack of backlighting on the display. 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.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source. By opening the panel, each LED can be checked separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect probes in the forward direction to it. In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the 715G6165-M01-000-005X motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). If it is not possible to replace the MB (SSB) card, you must check the health of its elements - CPU: MT5580PUEI; DRAM: K4B4G1646B-HCK0; NAND Flash: TC58NVG2S3ETAI0; SPI Flash: CAT24C128WI. Defective components should be replaced.
If the TV works normally from external devices, but does not tune into television channels, the TDSY-G720D 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.
Once again, remind users! Attempts to self-repair a PHILIPS 32PHT4509 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

715G6165-M01-000-005X can be used in TVs:
PHILIPS 42PFT6309/60 (Panel LC420DUN (PG)(P1) CODE 106), PHILIPS 40PFT4509/60 (Panel TPT400LA-J6PE1 REV:C1A), PHILIPS 42PFT6569/60 (Panel LC420DUN (PG)(A1)), PHILIPS 32PHT4509/60 (Panel TPT315B5-DXJSFE Rev-S1Z code 112).
The appearance of the power supply
Main features of the PHILIPS 32PHT4509 device:
Installed matrix (LED-panel) TPT315B5-DXJSFE Rev-S1Z code 112.
The matrix control uses the Timing Controller (T-CON) 32-37.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the PF7903BS PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 32PHT4509 television are generated by the 715G6197-P01-003-002H power supply module or its analogs using PF6200S, FAN7530 (PFC), ICE3BR1765J, FSFR1800US microchips and power switches of the STD432S, 2SK3569 type.
MainBoard - the main board (motherboard) is a 715G6165-M01-000-005X module, using CPU chips: MT5580PUEI; DRAM: K4B4G1646B-HCK0; NAND Flash: TC58NVG2S3ETAI0; SPI Flash: CAT24C128WI and others.
The TDSY-G720D tuner allows you to receive television programs and tune to channels.
