Asus G53SX Boots with black Screen

[passete]

Asus G53SX-SX116V
Motherboard : G53SX MAIN BOARD REV 2
It Boots, external Mouse and Keyboard are recognised, i also have sound.
But on internal or external (VGA & HDMI) display stays dark.
I have replaced : CPU, RAM, BIOS and made a light Reflow, still the same result.

Any tips my friends ?

Solved with a real reflow, using scotle ir360 v3
Sometimes i forget that nothing replaces a pro tool.

Ok, i just installed a brand new Graphic card, guess what ?
System is booting, but the display (internal/external) stays OFF.
What the hell, i also tried the Lid trick, same result.

reball previous gpu

Why should i reball the old graphic card, if i bought a brand new identical card ?

Just found the culprit, it's the PCH SLJP4.
I'm going to replace it, reflow seems to work a few times
