My old acer aspire v3 571 g laptop showing no bootable device in a blue box screen

When my laptop boots up it usually blinks an orange light of hdd near the sd card reader but when i turns on it shows blue light for a second and goes and no light later.Please help when i connected the laptop with a monitor nothing is showing and my screen i broken im stuck pls help I love this laptop and has been using it for over 7 years its performance is still butter smooth in windows 10 pls help

The first issue, the intermittent HDD boot error suggests either its connection to the mainboard needs to be re-seated a few times to clean its contacts OR it is starting to fail.

The second issue, the broken screen and no external monitor signal, suggests that the mainboard has been damaged. Did the screen break from a fall onto a hard surface?
