Solved! Black Screen on HP 17-e117dx

[CowboyDon]

I have a 6 month old refurbished laptop which recognizes any external monitor, vga or hdmi, but not the built-in screen. I have:

-reinstalled windows 10
-reinstalled the amd drivers for the radeon built-in 7640g video adapter
-did hard reset
-doublechecked the (2) 4gb simms
-tested for slight image with bright light on screen

and nothing worked, yet.

Please help!!!

Oh, and doing the hard reset worked a few times but now won't work.

If all that isn't resolving the problem, then it is either the ribbon cable that connects the display or the display itself that is the problem.

In this case, you would need to replace the part(s). First check the ribbon cable that connects the display. Is it bent, torn, pinched, loose, etc.? If so, replace that. If not, then the display would need replacing.
