Well, suddenly it worked again. But I waited the whole day >.>

I had one with the same problem. All the capacitors in the power supply were fried. If you're good with electronics, you can pull it apart and replace them (about 8 bucks in parts) or take it to someone who is.

Hi..there,
You've got a busted backlight inverter... Need to replaced a new one...
SOURCE: ACER AL1914 LCD Monitor goes black but green light stays on
The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the
inverter(power plug). Parts that go are the backlight ccfl's, behind
the plate, and parts of the inverter, ie capacitors, all three take a
bit of power from the inverter. The self test check that all the lights
are ok and the inverter is ok, else it switchs off, ie if 3/4 light
work it will switch off(my own case), hence the on chech error then
off, However sometime there are stages of on/off ie on/ but no screen
display, if that is the case the following may be of help...if you put
bright light at an angle close to lcd can you see a windows shadow,
text icons etc, ie still logic power passing,then .... (from a.n.
other) after two weeks searching I finally find doctor living stone

the takening the case bit off is like opening your wallet a second time
after buying a new LCD, but you must! smallest two screw driver's flat
headed, practice using two pennies stuck together()with your fingers
after, one little () move and inch and {} again, with the case , it
does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip
inside!] also note the bright light test to do first to see if can see
a windows screen , and that capacitors are one for a number of things
that a make a inverter work! there a transistors as well, given that
however, to replace all the capacitors on my inverter, was 11
capacitors, cost me $11 (uk ebay) and already had the iron and solder.
So only cost me me $11 to try and see but no luck , still fun and I
still can see the screen for 2 sec' at a time plus I have a spare set
of caps now in the event that the new one do go burst! you have to
laugh really, what next , a new on/off button, as you work though the
whole inverter mmmMMMMmmmMMMMmmmMMMMTim
Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not
wellMMMMMMMMMMnnnnnnweek later land sight
mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the
inverter. If it went out over a slow period of time (flickering etc..)
I would bet it is the lamp.replaceing the lamp should be pretty
challenging. as that requires complete breakdown of your LCD,
extraction of your dead lamp, and soldering in your new lamp... but I
would like to say that I it did this after realizing it's 2 x kitchen
strips inside [========] with wires that can connect back to the
inverter with out any desoldering(ie kit assembly/dis) with the outter
case remove (glass plate safe away) I could reconnect and see that 3/4
were working (i!i hardcard ) cause the inverter to switch off after a
secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a
1/3 of the price ! the market as drop out there, hope the inverter does
not miss the length, or the screen out
put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR
MONITOR
SOURCE: acer v193w monitor screen is black, and an amber
The blinking Amber light can mean two things, one is that the monitor is not getting the video signal from your PC, or it can be problem in the monitor power supply due to bad caps. Please try it on another PC first before opening up the monitor. If is it the monitor then read below so you can make up your mind if you want to DIY or not.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

A solid green light means the computer is operating normally.
A solid yellow light indicates the power supply is operating normally but the computer is not processing data.
This could mean there is a problem with the CPu or another component on the motherboard.
((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))
A blinking green light means the computer is in standby mode.
You should consider visiting Dell Support and downloading the manual for your
your Dell computer. So use the LED power light codes if your Dell computer has them.
hope this helps
