this is my first post here, so please be patient if I'm wrong with some description.
A laptop Asus X53S-SX607V has a LCD panel problem. When the laptop is powered on, the backlight is on as well (can see the white light in the bottom background). There is no picture nor Asus Logo at boo time, I can see only a gray static texture very light, and normal LED activities.
The external monitor output is perfect, the boot is perfect and the OS loads without a problem.
By forcing the switch between LCD panel/ext monitor with the F-key, the LCD panel get the backlight ON all the times , but is still without any image.
What could be the reason?
nVidia chip? Inverter? LCD panel ?
Thanks for any help here
