Acer AL2216W's green light goes off completely when the computer is turned on. When I turn on the computer and monitor, there is green light on on/off button while an irritating Acer logo is showing up. Suddenly green light goes off and screen becomes blank. I do not even see an orange light. I have already tested my computer system and cables. They both work fine when plugged into another monitor (HP 2009m). Please tell me what the problem is and how it can be fixed.

well you can test the monitor an any PC made, to see if the problem is the monitor .
easy no? just one simple test. I guess a VGA cable.
That old monitor uses CCFL back lamps. that most at dead now.
after 10 years of service they are DEAD. most are. now.
Green means not sleeping.
when PC goes offline the Monitor tells you ,
lost signal, going to sleep, no sync, or out of range.
all monitors made 2000 to now do that. every one.
the OSD dead. test.
so when you turn the monitor on , and push menu button
in under 5 seconds, does the monitor show the OSD screen.?
it will do that even if PC is turned off.

The OSD is the tiny brain in the monitor. on screen display.
if you test the monitor with a flash light when it goes black with
PC on.
and you see data, that means the CCLF are dead.
the do that, all do this now. dead, intermittent, stobes, or yellow for white screens. all do that at 20,000 hours. used.

value if the monitor is $20 working , or $5 not.
so repairs are not all that econ101 giving this fact.

If the power light does not come on and it makes a screeching noise, most likely its broken. I would contact the manufacturor, in case some warranty left.

It will go into sleep mode if it does not detect the signal from the PC. Try is with other PC first, also make sure the cable is seated properly.Basic LCD monitor and TV troubleshooting guide:

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Here is the inside of your monitor:

Go to Control Panel, (top right View Small Icons). Then look for Power Options. On this page, you'll have the option to leave the monitor on. You should also check "Advanced Power Options". Don't be afraid of the word, "Advanced." It only means "customizeable"

If your mouse isn't waking your monitor, try the keyboard's space bar. I found it works better than the mouse at waking a sleeping computer

Does it do the same whan attached to another PC? Cables are good?
If it is monitor, you will need to check the caps and DC voltages first.

Hi there reinstall the display driver & then give a look. If you face same problem then its may problem with your display driver or in the monitor.

Look for bad caps first, worst case will be bad IC/MOSFET in the inverter circuits which will need in-depth component level troubleshooting.

Please post back what you find.

The screen is bad, verticle lines, red or pink hue etc. is indicative of a bad screen or there maybe a problem with the data cable you are using to attach to the computer. Try another cable first, if the problem persists, the lcd panel is failing.

Replace the following capacitors:

3 pcs. - 220 microFarad - 25v
2 pcs. - 1000 microFarad - 25v
1 pc. - 2200 microFarad - 25v

Resolder the 2 inverter transformer's legs.

LOOKS LIKE A BURN SOLDER !! , open the monitor , check the PC BOARD around the transformer area , look for burn spot or cold solder , RE solder it , try again , hope this helps please rate solution and thanks AJ
