Asus x55vd Black Screen!!!

[stefano81]

Hello to All,

The issue for my asus x55vd rev 3.1 with windows 8 is that you turn the laptop on, and the power lights come on, but nothing on the screen.. no post, nothing.. I can hear the hdd, and fan start but the screen stays black.
I have tried removing the battery and the bios battery, and discharging the power by holding power key for 30 seconds, and starting on mains, but no luck. I did reflow also the vga video replacing the old thermal paste with no luck.

I have read of some forums that it could be a corrupt bios so I downloaded the file bios.bin Asus X55VD Rev-3.1 but I hope somebody could help me how to flash the bios from usb booting up with a black screen.

Does anyone have any suggestions for a fix please?

Thanks

Stefano
