Leonovo Ideapad 720S-13ARR display flickering

So I have a Lenovo Ideapad 720S-13ARR and the display is flickering. See the video here: https://streamable.com/14qji6

The first few seconds of flickering in the video is actually the display getting very dark. When I change the display brightness again it actually starts flickering.

So I have googled around and there are some threads that say that a driver update of the AMD Vega 8 graphics unit is responsible for this. Therefore I tried to get rid of that driver by uninstalling it entirely, however, to no avail. Without any AMD graphics driver (i.e. with the basic windows display driver) I still have the same issue. Even when entering only the BIOS, the display is very dark and/or flickers.

I still don't want to believe that this is a hardware issue. Any other ideas?

A flickering and darkening display as described is a hardware issue. The same flickering and darkening occurs in BIOS and in the Operating system. BIOS is very basic and so a display hardware here that is the same as in the OS is a hardware problem.

Problems: Backlight gone bad, cable seating or issue, and possibly the display as well.

Solution: Get the laptop serviced and have the defective parts replaced.
