PHILIPS 65PFL9708S General recommendations for TV LCD LED repair
If PHILIPS 65PFL9708S has no picture, but there is sound, often the backlight of the T650QVD01.1 display simply does not work. Moreover, in LED TVs, the LEDs inside the panel usually fail, less often the LED driver.
In such cases, you can see a barely noticeable image with a successful hit of external light on the screen.

Replacing the LEDs requires disassembling the T650QVD01.1 LCD panel - a process that requires experience and qualifications from the master. We do not recommend doing such work on your own to the owners of TVs and craftsmen who do not have experience in repairing LCD panels

If there is no image, and the backlight is on, the screen becomes slightly lighter when turned on, and in an open TV you can see the light through the holes in the panel case.

In this case, the panel may also be faulty - damage to strips, loops, for example, as a result of moisture ingress after unsuccessful washing of the screen, the T-CON (Timing Controller) board may be faulty. But often the main board MainBoard 310430354946 also turns out to be faulty, a software failure is also possible.
Then, first of all, you need to check the panel supply voltage, the fuses on the T-CON board, as well as the supply and reference voltages of the column and line drivers - VGH, VGL, Vcom.

If these measurements are within the normal range, it is necessary to trace the passage of LVDS signals from MainBoard 310430354946 with an oscilloscope, as well as synchronizing signals to the loops with drivers.
Flooded or unsuccessfully washed screens of LED TVs can be restored, in about half of the cases, usually if significant damage has not formed in the loops and panel strips.

The main features of the PHILIPS 65PFL9708S device:
The matrix (LED-panel) T650QVD01.1 is installed.
Matrix control uses Timing Controller (T-CON) 715G5898-T0E-000-005K.
The LED driver 4H V3526.001 is used to power the backlight LEDs.
The formation of the necessary supply voltages for all nodes of the PHILIPS 65PFL9708S TV is carried out by the FSP377-5F01 power module, or its analogs.

 

Attention to TV owners! Attempts to repair PHILIPS 65PFL9708S yourself are not recommended by the manufacturer and can lead to serious negative consequences!

Attention! Panel T650QVD01.1 LED TV PHILIPS 65PFL9708S 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.
