Question about Acer AL2021M (Silver) 20" LCD Monitor
Hook up to external monitor .. Does the pre boot screen pop up (black and white writing at start ) ? If display runs on external monitor then your screen needs replacing usually or if you see a vague image on laptop screen then inverter or backlight is gone .. if no display on external and no pre boot screen probably the graphics chip on laptop has malfunctioned.
