Finlux 32h7072-no backlight

[Bizzy80]

I have a Finlux 3d model 32h7072-dt and last night when i was watching a tv program the screen went off.
The tv starts,has sound and picture(when i look very close i can see it) but no light on the screen....everything else works...if i press menu i can (barely) see it
When i start the tv sometimes it has backlight light for a second or so....sometimes i can see it's connected to hdmi1....I have minimum to medium knowledge about electronics...someone can help me...where to start from?
Any help will be appreciated.

I will post some pics when i'll get back home as i'm away right now.
As an update when i was trying all the options on the menu( with a flashlight to see it properly) ...on power save mode when i was choosing eco mode the screen sometimes was getting on...like for a 1/2 second

I have atached the pictures:full back and each board...sorry about landscape/portrait mode...i was trying to get a closer and clear picture.
I've looked at the psu board and there is nothing showing damaged...no blowed caps or some other signs
I did make a test on the led output...when i power up the tv is somewhere around 90v then drops and fluctuates between 27.1-27.3v
