In the device manager there is no built-in display located. The Intel UHD Graphics are displayed and only the external display is visible. The AiO turns on and works but is only showing a black screen on the monitor.
I checked the voltage on the backlight connector and it reads ~20V. I tried reseating the LVDS and Backlight connector, yet the image still does not show.
Does anyone have ideas whether or not this is a BIOS related issue? The only visible log in the BIOS logs is that the firmware was updated around a month ago.
We already tried to fix it by resetting the BIOS (Taking out the 2032 battery and putting it back in) but it did not succeed.
Any help or advice is appreciated, thank you.

I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
