Laptop Lenovo N585 Brightness Does't Work

[crdz66]

Hi Friends.

I need you value opinion on this problem.

Laptop Lenovo N585
Windows 8.1
AMD VIDEO CARD.

This laptop come to home with non brightness or video.
I hook the laptop use a external monitor and was working good (on external monitor)
So, I proceeded to replace the led screen and as soon I get it installed the backlight works good for a sec and continue super low brightness and good video.

I can't manipulate the adjust brightness button because doesn't respond.

Now I'm working updating the video driver and after this going to play with safe mode.


Any another ideas what is happened??
Thanks
