Re: asus k55a no display

Hi all
I've got similar problem, I've got picture but no backlit. HDMI and CRT work fine. Because I cannot find motherboard schematic it makes it even more difficult. I've checked all lcd pins and I've got 19V, 3.5V, 1.3V, 1V and 0.3V. Can anyone help please?
P.S. I've tried 3 different LCD screens.
Thank you
