The first thing to rule out is overheating (CPU, motherboard, hard drive or power supply)
then I would check for bad memory (if you have two modules - swap them out for testing)
then I would test with another power supply
only after I have checked ALL of these would I think it was the Motherboard.

My HP laptop was working fine, and then suddenly the screen went blank. When I reboot, the power light stays on and you can hear the hard drive spinning, but the screen stays blank.


Hi,

unhook all usb cables and power cable, take out battery. Hold down Power button for 60 seconds, which will get rid of all static electricity. Plug in all cables again and check.

If still facing problem there will be some connection issue inside the lap.
Please let me know whether this works or not.

Ny acer aspire one only shows blank screen


The backlight have went out on your screen. I had this happen on an old laptop2_bing.gif I was messing with. Check the link below for some tips.

DARK SCREEN If you shine a light on the screen, can you somewhat see the screen? Does the laptop power up properly? (can you hear it running?) Hook up an external monitor to your laptop, does the external display properly?

When the filter caps went bad, the power supply output will be AC and feeding the circuits which can damaged the parts on the board. Check to see if you have the 12 or 18v feeding the back light invereter board. There are surface mounted fuses on the inverter board also. Send me good pictures of the whole back where all the boards are and close up picture of the inverter board, may be I walk you through. budmrtn@aol.com

ACER PICTURE PROBLEM – MY SOLUTION

I had a similar problem, but I got a picture before it broke up and went off. The screen was backlit, but no video (screen was receiving some power).
The LCD needs a very stable voltage to work, this is provided through the LCD connector ribbon. In my case the ribbon was damaged and replaced it.
I have had no problem since.

I discovered this through trial and error; I first changed my transformer power supply and then the video inverter card.

You may find the link below helpful as it contains articles that photographically show you how to open the laptop for repairs.
