internal black screen - hdmi works fine

i’m hackintoshing my old laptop which is a toshiba satellite pro A50-A-10V with these specs:

  • i5-3230m
  • 6gb 1333mhz ddr3 ram
  • hd 4000

My problem is that i couldn’t see anything from the integrated display, by the way it gets recognized by the system and i can change its brightness… i could only see the os when i connect it through an hdmi cable which put the signal on the tv…

Thanks in advance… any suggest is welcome
