monitor won't turn on, light flashes

Help! My flat screen monitor won't turn on now. It started last night. The power light flashes every couple of seconds and every once in a while you get a quick glimps of the main screen but then it goes black. We have tried turning it off, unplugging it, all the stuff and nothing works. Wondering if anyone can help?

I don't know the model of the computer. I am at work so I can't look it up. It is a flat screen monitor. We can hear the computer running, the speaker work and we can see the lights on all parts. I have unplugged, replugged, and restarted everything I can think of. We completely disconnected it from everyhting and reconnected it back up with no luck. the power light on the monitor keeps flashing on and off and if we try to hit another button, like to adjust monitor settings, nothing happens.

You should mention your computer model and operating system and whether or not you can hear the computer running. Sounds like your computer could be sleeping or hibernating. Press the hardware button on the computer (not the monitor) briefly and see if it wakes up. If not, hold down the button until the computer turns off and wait 30 seconds and restart. If that doesn't work, you might have a video card or other failure. Of course you have rechecked all your cable connectors and diagnostic lights on the computer. Attaching another monitor would be a good test.

Most Dell flat panels provide a self-test feature that allows you to check whether your monitor is functioning properly. This is accomplished without connecting your monitor to the computer. The steps involved vary by model. Go to the link to find your documentation. http://support.ap.dell.com/support/systemsinfo/documentation.aspx?c=hk&l=en&s=gen&~cat=3

First thing you need to do is test if the monitor is faulty, or if it's an issue with your PC.

It might be hard, but you have to try the monitor out on another machine. Preferably with a different VGA cable to ensure the cable is not at fault.

If it works fine, it rules out the possibility of the monitor being faulty, and you can go from there.

Basically it could be 4 main things:

1. Your monitor is faulty

2. Your cable is faulty

3. Your machine/graphics card is faulty

4. It's a software issue

Let us know what happens if you test it out on another machine.
