When I boot up my computer & turn monitor on the indicator light on the monitor turns from inital green colour to amber and I only get an on screen message of "power saving mode". There is no image of the computer booting up or XP starting, just black screen. It was working fine one minute and then after shuting down and then re-booting not long after I encountered the problem.
Sometimes an old driver for this monitor will mistakenly believe it can
display a higher resolution - and so it goes out of range when things
Step one - if you can, connect to another monitor, or your tv, with both old and new hardware installed and simply download and install the new driver.
If that doesn't work, boot into safe mode (it naturally sets a lower resolution).
And when all else fails.... Best trick I've found is to clear your CMOS (reset your BIOS)
and, oddly, plug in a different keyboard to a different port and hold
delete when you boot. If you need to repeat, change keyboards again.
(make sure you hold the delete key down before you even plug the
computer back in and it should work fine.) Also, for those unfamiliar
with resetting their BIOS, write down your settings first, or ask a
G'luck! Took me some research but I eventually made mine behave. :)

Hello Chelleydiao, hi, its either you have a CPU problem or the monitor itself. Check or use another monitor to see if the problem is fix. you see an blank monitor can also be caused by the CPU if it fails to boot. the aid the checking, do you see any orange light on the monitor? or any indication.... the led light on the screen in summary: green or blue means there is power and the CPU boots up.
if orange the CPU fails to boot, if there are no lights on the Monitor panels, there are problems on the monitor. check these first....I need a much detail description.
I will assume that you have checked out the power cables and external cables. If this is the case you will usually notice an indicator light from your monitor. Universally it is yellow or orange when it has power, then turns green when it detects input from your computer. If the Led light doesn't turn green even when your laptop is already booted, your culprits would be your iMac's video controller or your monitor's input cables.
correodemie, Your ACER AL2016 will need to have it's "switch-mode-power-supply/CCFL inverter supply" trouble shooted and repaired. DIY repair cost less than $30. Out of warranty service $35 to $75, more if circuit board replaced. Read my and other techs FIXYA profiles to discover all the options you have for your BLACK screen symptom. Follow the links to other web sites for even more useful info. DO THAT before you do anything else. 12fixlouie
no signal indicates a couple things... i suspect your computer isn't even booting up. reboot the computer while tapping the F8 key.... you should see writing on the screen... boot to safe mode. after it sucessfully boots up... reboot again... should be fine.
