General repair guidelines for TV LCD LED
Possible manifestations of defects
- PHILIPS 40PFT5300 does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
In some of these cases, the main switching power supply - module 715G6353-P01-001-002H is found to be faulty. Then it is necessary to measure its output voltages and, in case of their complete or partial absence, it is necessary to check the serviceability of power switches (TK15A60U (PFC), TK13A65U) and rectifier diodes of converters for possible short circuit.
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.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM circuits (PWM) SSC1S311, LD7591T (PFC) are usually checked by replacing with new, or obviously working.
- 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.
Often in such cases, there is no LED backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to check the LED line for breaks 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, as a rule, light up a single 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 a health indicator. In faulty LEDs, the zener diode will either be cut off or broken into short-circuit.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the 715G6165-M02-000-005N motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: MT5580, EEPROM: 24128E, eMMC: P95L-4KA1-JW963 requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
Before replacing the TDSY-G720D tuner, if there is no tuning to the channels, you must first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Attention TV owners! Attempts at self-repair of PHILIPS 40PFT5300 are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the PHILIPS 40PFT5300 device:
Installed matrix (LED-panel) TPT400LA-J6PE1 rev: SC1M.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the LD7890GS PWM controller. As power elements of the LED driver, keys of the type EMD60N10F are used.
The necessary supply voltages for all nodes of the PHILIPS 40PFT5300 TV are generated by the 715G6353-P01-001-002H power supply module or its analogs using SSC1S311, LD7591T (PFC) microcircuits and TK15A60U (PFC), TK13A65U power switches.
MainBoard - the main board (motherboard) is a 715G6165-M02-000-005N module, using CPU chips: MT5580, EEPROM: 24128E, eMMC: P95L-4KA1-JW963 and others.
The TDSY-G720D tuner allows you to receive television programs and tune to channels.
