I have been given an Acer laptop by a friend screen keeps blinking off every few seconds, Cant see any boot up screens, bios, windows bootup etc.
heres what I have tried
Running battery only - still does it
Running Mains & Battery - still does it
Mains only battery removed - still does it
Laptop display not affected by screen angle
Connect and external monitor via DVI - still does it
Install different versions of Nvidia Drivers still happening, tried latest from Nvidia site & drivers direct from Acer website.
If it was a screen inverter board, I would think it wouldnt do iton the external monitor.
As it doesnt display anything on bootup I think it is hardware.
