Acer Aspire 5650 screen blinking on and off

March 28, 2011 at 03:53:38
Specs: Windows XP MCE, Intel Centrino T2300/512mb
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.

Any ideas?

Sounds like you have either a bad graphics card or motherboard. If you have a graphics card that you are able to reseat the connection on, it couldnt hurt to try that first before buying new parts.

If builders built buildings like programmers wrote programs, then the first woodpecker that came along would destroy civilization.
