So for the past couple of months my monitor Acer AL2216W has been repeatedly turning off and on, until I would unplug and plug it back in enough that it would work (this took about 10 minutes). If I turned off the monitor for long periods of time, and turned it back on, it would keep turning off and on and off and on. Now it won't even turn on, what happens is that the light on it turns off and on, but not the screen, like it usually does. I REALLY need some help with this, since I don't want to throw that monitor away. My graphics card is a Nvidia Geforce 9600 GT, but I am not sure that has a lot to do with it, I feel like it might be something wrong the the power supply, but I have changed the power cord multiple times. Thank you.

Hi, Simple tests

Take to monitor and hook it up to another computer and see if it works.
Hook up a different monitor and see if it works.

My guess is a hardware failure in the monitor. The only way to tell which one is the problem is doing the simple tests above.

You say you changed the power cord multiple times. Does the power cord have the AC Adapter in it or is it just a straight wire?

Normally I would expect the problem you are describing to be bad capacitors inside of the power supply inside of the monitor.

Good Luck
