Philips 43PUS6554 black screen

Hi !

Since few days, my 43PUS6554 Philips TV (3 years old) got a black screen, audio is still working. Backlight is still working. Tried to light up the screen to see if i could see anything, but without success sadly.

Here is pictures of every boards of the tv.

Do you see anything unusual ?

I tried to find a service manual but with no success sadly :/

Thanks in advance !
