Acer Aspire 3 A315-41-R9NM black screen (after update?)

Lurching

Hi,
The computer has this issue that suddenly the screen doesn't work anymore. When trying to access the BIOS or to duplicate the screen view (using an external screen), whatever is done, the screen remains black. Tried to update the screen drivers from AMD as it is Radeon VEGA graphics. Nothing helps so far. Also I've tried to install the Acer Care Center app but there's no diagnostics for the screen in that app. 

Tried to update the BIOS and the screen seems to ligthly flicker at boot time, but displays nothing apparent.

Any recommendation? Thanks in advance!

In the end it's the screen. It has been swapped for a new one.
