NUC8i7beh Very strange screen with no bios boot, is it dead?

Hello guys,

Hopefully someone has a good suggestion.

So a couple of days ago i was making some changes in my bios , I switched of the function of sending sound over the hdmi as and audio output. When rebooting i only get this distorted screen, the same after switching to a usb-c dongle with video out.

Tested on multiple screens with multiple cables, but really seems to be the nuc.

Tried to clear the bios with the jumpers, the self recovery bios via a bio file.

It seems to be responding as it used the usb stick and restarted after a couple of minutes but after that the same.

Sometimes some text is visible in the 2 black lines but it never seems to respond to any keys/input.

Removing the optane SSD does not help, and the trouble shoot led just stays on and does not blink.

Since i use the nucs in custom casing i know there is no chance for an easy warranty case, so i hope some-one here has a good suggestion to try.

1. The problem what you see was probably caused by changing the value of IDG Aperture Size.
2. Try to enter bios settings from the Power Button Menu:
3. Press and hold the Power Button for about 3 seconds - count 1001, 1002, 1003, 1004. Release the Power Button, the NUC should boot into Power Button Menu.
4. If you see the power Button Menu, press F2 to enter into Bios.
5. Press F9, followed by "Y" (to set bios default settings) , and then press F10 confirmed by "Y", to save the default setting and exit to Windows.
6. If you can't see the Power Button Menu, try the following:
7. Power ON your NUC and repeatedly depress F2 in order to enter bios.
8. Repeat paragraphs 5, giving a few seconds between each click on keyboard. In this way you may try to set default setting without seeing the display.

Wow, thank you very much dear sir.

You are my digital hero, really thought i could throw this one in the trash.

The back light on my keyboards did not turn on so i really doubted if it would receive any input at all.

But following you're guide everything was quickly resolved.

Not often i feel like a digital noob, but in this case im very happy.

Thanks again!
