Hello to all,

I received for repair Asus notebook X55U Main Board, REV. 1.4

On the motherboard there is only AMD C60 CPU and AMD FCH 218-0755113.

When the notebook is powered on, there is only light on the notebook panel, no image at all.
When I connect the external monitor, I have picture.

Someone already reballed FCH and tried the other LCD panel, but the result is the same.

What I should do?

Thank you!

refer to the voltage on the matrix. stir to LVDS, just check the trail to start.
