Monitor Turning Off and on

[Meepugh]

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.

Have you checked whether the cable came lose when it turned off and on?

I think its cause by bad capacitors.

Have you tried the monitor on a different system yet? If you can't find someone to help you then im sure your local computer repairs shop will test it for free, at least I know the ones near me would.

Ps, I you do find out that it's just the monitor, be sure to replace the PSU anyway, there may be a slim chance that it could have caused the problem if it were faulty, better to be safe then sorry.
