Yoga2 Pro power on but no image

[ytsoc]

Hello all, i have this laptop , board is nm-a074 rev1.

I tried flashing main bios , no succes, same behaviour.

I would like to try to also flash the EC, problem is that i only have RT809F programmer. I'm unsure if supports this version of the EC.
However, i need the pinout to at least attempt to try and read it. i found a document for SVOD programmer, but it only describes the pinout of the kb connector, it does not specify what pin is clk, cs etc

Does anyone have this info? or any suggestions to fix this board?

did you test it using external monitor? before you reflash the bios.. did you replace the memory with known good memory..

if by memory you mean ram memory, i can't do that because it only has soldered ram.
