Acer Nitro 5 AN515-44 Black Screen of death

Hi guys!!

I have an Acer Nitro AN515-44, bought it 2 year agor (brand new).

For the past months, sometimes the display don't turn on (don't even show the Acer logo at startup), so I turn off holding the power button and then turn on again and the display work fine.

But now the display don't turn on. I work with another screend plugged in (HDMI), notebook work just fine, only the display don't work.

I search on the internet about it and tried a lot of things and no success

There all the things I did:

Disconnect all cables, turn off and hold power button for 1 minute for battery reset;
Restart and press F2 on startup to enter on the bios configuration, but the display don't work, so there nothing I can do.
Let the battery drain, wait a few hours, plug the power cable and turn on
Disconnect the battery plug from motherboard and tried to turn on with the power cable plugged.
Remove and clean the memomy stick
Remove display drivers
Reinstall display driver

Some symptoms for the problem

Looks like the notebook don't know the display, only detect the display on HDMI
Display don't flick and not show anything, just keep black like when its turned off;
Don't show Acer logo at startup
Notebook work just fine (power indicador, keyboards leds, speaker, battery, all ports (hdmi, usb, usb-c),

I was wondering if anyone here has any more tips before I change the screen.

Did you try to boot to BIOS with F2, is the primary screen working, reset BIOS with F9 and save on exit. Boot in Safe Mode and see if the primary screen works with Windows Base Video adapter only, select Internal Display only (see picture).

@Puraw like I said, the main display is not working, even on startup.

But i did what you said and restart in safe mode, and them began my nightmare. In safemode, windows only use the main display.

So I blindly exit from safe mode using these steps: https://www.reddit.com/r/techsupport/comments/14ojq8v/comment/k0wesci/

5: Then... press and hold "WINdows Key", then press, "R" then let go of both.
6: Type: "msconfig" and hit Enter.
7: Wait 10 seconds to let this new thing open.

8: Now press: Up Arrow, Up Arrow, Enter, Tab, Enter. And pray that you did everything correct. If you did, the computer will restart and the second monitor (TV in my case) will come online and you may give this post an upvote.

If in Safe Mode, the Internal Display is working you don't have a hardware problem so no need to "change your screen" as suggested in your first post. What you need to do is disconnect your external devices (monitors, USB consoles/mouse) and carefully follow these directions: https://www.intel.com/content/www/us/en/support/articles/000091878/graphics.html
You only have AMD and Nvidia display drivers so ignore the Intel reference in the above link, DDU can also handle AMD, Nvidia and Realtek, uninstall everything related to display drivers, graphic consoles, anything that DDU finds for both AMD and Nvidia.

Don't install any drivers, don't connect your external display, make sure internet is working and reboot, Windows will reinstall the correct GPU drivers.
