General recommendations for TV LCD LED repair
Possible malfunctions
- PHILIPS 43PUS6503 does not turn on and does not show any signs of operability at all. Does not blink indicators and does not respond to control buttons.
With similar manifestations, a malfunction is most likely found in the 715G9324-P01-001-003H power module. It is necessary to measure the output voltages in its secondary circuits, and if they are completely absent, the serviceability of the power switches (TK13A60D, IPA50R800CE) and rectifier diodes should be checked for possible breakdown (short circuit).
In case of breakdowns in the secondary circuits, the converter can operate in short-circuit mode, and in case of short-circuit in the elements of the primary circuit, the mains fuse usually breaks off.
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) LD7592, SSC3S927 are usually checked by replacing them with new ones, or knowingly working.
- There is no picture, but there is sound and all other functions work. Sometimes when you turn it on, the image appears and disappears for a second.
In such cases, the most likely malfunction of the LED panel backlighting elements. Usually the cause of the malfunction is in the breakage of the LEDs, or in the connectors of the LED strips, but sometimes the LED driver is also faulty.
To check the LED lines for breakage without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter; a voltage of the order of several tens of volts is required.
- The indicator blinks or is on constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the 715G8709-M0B-B01-005K 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). In cases of complex MB (SSB) repairs and with the necessary skills and equipment, it may sometimes be necessary to replace its MT5802VGEJ, M24128-BRMN6TP, THGBMDG5D1LBAIT chips and other possible faulty components. Malfunctions associated with the use of BGA soldering technologies are usually easily diagnosed by the warm-up method.
If the TV operates normally from external devices, but does not tune to TV channels, the TDSY-G480D & TDQS-A701F tuner may malfunction. In such cases, first of all, you should make sure that the supply voltage is present at its corresponding terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the reason for the inoperability of the tuner may be a software failure.
We remind users again! Attempts to repair the PHILIPS 43PUS6503 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

Attention! The TPT430U3-QVN03.U panel of the PHILIPS 43PUS6503 LED TV is an expensive and unreliable element.
Do not allow any impact 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.
