Try resetting the power settings.

In Windows, go to Device Manager.
Scroll to the Mouse section and select your device.
Right-Click > Properties > Power Management tab.
Check "Allow this device to wake the computer".

Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your Monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Hello there, first thing you should do is to check the power cable.You can do that by changing it with PC power supply cable .It is the same. If it turns to be OK then disconnect the VGA cable from monitor and then try to power monitor on.There should be an activity on front power LED. If the power LED is not showing any light at all, then do not go further the unit is not working .Else the power led should blink a couple of times then a window pop up scrolling on the lcd saying :" no video signal" so the unit is OK ..Hope this helps. Cheers.

Hello,

This is a very common problem with this model after a few years of use. This problem is caused by a failure of the capacitors in the power supply board hat powers up the back lights in the monitor. When the back lights don't power up you get no display on the screen. Here is a link to a repair guide for that model that shows how to open the unit and what to look for and replace to repair the monitor.

Here is part one of the three part video repair guide posted at the above link:

Your monitor has a self-test feature. Have you tried using it? The link below will give you directions on how to do this. It will also give you information on common problems.

Same problem as above. Had mine for 2.5 years and worked fine until I tried to turn it on this morning - won't come on at all. I have tried another power cable and verified that another monitor works on the old one.

Try this settings:

Click on Start | Control Panel | Power Options.

In the Power Option properties window, click on the Power Schemes Tab

Set the Turn off Monitor/ Turn off Hard Disks option when on Power (and also Battery for laptop users) to Never.

Now click on the Save as... button and assign a name to this power scheme... Let us call it 'Presentation' and then click on OK.

That's it congrats!

Do a reset: Turn the computer and monitor off. Unplug the monitor video cable from the computer and unplug the monitor power cord from the wall outlet. Let it sit for 5 or 10 minutes. Plug everything back in, turn on the monitor, then start the computer. Sometimes that will work.
If you still have the same problem, try to borrow a known to be good monitor from somebody. If it works, then you know your monitor is bad.
It's also possible that your video circuitry is bad. If the monitor plugs straight into the motherboard (onboard video), then you'll need to purchase a video card and install it. Disable the onboard video first.

Does it occassionally turn on or does not turn on at all? I advise that you try a hard-reset(disconnect completely from power supply for about 2 hours). If it doesn't work then you will have to get a replacement inverter board.Let me know how it turns up so that i can assist you further. Thanks for using Fixya.
