Hello community,
I am writing since I am out of ideas after having tried a few things.
My problem is the following:
My laptop (Aspire v5-591G-50BA aka V15) does not recognize the screen most of the time. In more detail, when I turn on the laptop the screen just remains black and does not seem to get any power. When I connect an external display everything works fine. However, when I check the connected displays the system only recognizes the external one.
Additionally, when I turn on and force shutdown (pressing the power button for a few seconds) the laptop around 10 to 20 times the screens lights up eventually and everything works fine. Once the screen went on, I can shake it, move it, close the lid, basically do whatever I like and the screen will stay on. I can even restart the system after it once worked and everything's ok. However, when I leave the laptop turned off for a short while the display won't come on again.
What I tried up to now:
- Upgrading the BIOS
- Draining any static potential, by taking out the battery and pressing the power button for up to 2 minutes
- Checking the connection of the diplay to the motherboard (seems ok)
- Checking if the problem is related to a faulty backlight using a strong light source and lighting on the screen. (nope, not the case)
- Checking the RAM (although since everything works fine on the external display, I didn't expect much)
- Update any related drivers (although since the screen doesn't even show me the POST, I didnt expect much)
- Trying to turn on the laptop in any screen position you can imagine (even upside down with the lid open for a few degress only 
)
- Turning off any sleep mode, hibernation, fast boot etc. in windows.
Unfortunately, I am out of ideas now and I'm about to order a new screen, unless you have an idea about what could be another source for this issue.
Thank you very much in advance and I really look forward to any ideas from your side!
PS: Although it might not be relavant, but I am using a dual boot configuration using the grub bootloader.
