Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Check Acer's website for a BIOS update. I've seen a LOT of laptop's screen issues been related to the power saving settings in the BIOS. Sometimes screens going black very fast and not working properly can be caused by that.
The Power Inverter could also be the problem which you wouldn't be able to repair yourself. If you purchased it at Best Buy you can take it to them and they could get that fixed for you (at a charge if there is no warranty with that).

Change the settings from the display settings panel. (Right click on the desktop and go to display settings)
You should see 2 monitors graphically represented there.
You can make the monitor that is greyed out active by right clicking on the monitor, and selecting active.

Hopefully it is this easy. The Fn and left arrow combination should dim the screen. To brighten the sceen, try Fn and right arrow.
If this does not work, then try other combinations using your Fn key to make sure the Fn key is working.

See http://macles.blogspot.com/ . I had similar symptoms and shipped it off to Acer for repair and it was returned with new level of BIOS as only repair. The macles blog has directions/links for upgrading the bios on an apparently dead machine, if you'd like to try it yourself.
